Three Steps to Ignite Your Enterprise Digital Journey

July 7 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco & Cisco Network, #Cisco News, #Cisco Technology - IT News

What’s new? The network is an informational highway of intelligence, but today’s static infrastructure can’t see the intelligence. The first step in addressing this issue is increasing visibility into the network with insights and analytics. Next is automating network services to make it easy to deploy, manage and maintain.

Cisco’s new network innovations address both challenges, and include:

Insights and Experiences:

  • Cisco Connected Mobile Experience (CMX) 10.2.2 – a software update with new features and enhancements for better customer engagement, operations and streamlined guest experiences
  • Cisco Aironet 1560 Series Outdoor Access Point – Cisco’s first outdoor Access Point that extends 802.11ac Wave 2 Wi-Fi to high-density environments, the foundation to enable CMX for your outdoor environments.
  • Cisco Catalyst 3650 Multigigabit Switch – a new Catalyst Multigigabit technology (based on NBASE-T standards) switch with up to 48 ports (12 MGig) and UPOE up to 60w for voice, video, and data performance assurance

Automation and Assurance:

  • ASR 1001-HX and ASR 1002-HX– new fixed –HX chassis that offer WAN edge high availability and resiliency with Service Level Agreement (SLA) assurance in a small form factor.
  • Cisco Unified Compute Services (UCS) E-Series – new 6-core single-wide compute blade for ISR 4000 with enhanced processing, memory and storage for 2x more app hosting.
  • 3rd Party App Hosting on ISR 4000 & ASR 1000 Cisco now supports KVM-based application hosted as container on Cisco Enterprise Routers, providing more choices and openness support for 3rd party or custom application.

What are the challenges Cisco is helping you overcome?

The roadmap to a digital network may seem simple, but there are significant challenges that must be overcome. With these new network innovations customers can tackle:

  • WAN Edge Challenges–The WAN is the fabric that connects users to apps and things. It also is the central point between the enterprise core and its edges—from the core to campus/HQ, branches, cloud and fog or among enterprise private data centers. The WAN edge must balance between performance, visibility, and security to ensure the best user experience (i.e. quality of voice, video, and data).
  • Branch Challenges–The branch is the first node of connection for users and guests to apps and things, as well as the first line of defense to nullify a threat. Given its small IT footprint and often remote locations, the branch challenges include application experience, connectivity, management and automation, threat detection and defense.
  • Customer Experience Challenges–To deliver a personalized customer experience, two integral steps must happen in tandem: (i) ubiquitous and robust connection, indoors and outdoors, and (ii) user, app, and device intelligence.

How will the new innovations help customers?

This is always a question we ask ourselves when rolling out any new technology. Focusing on real business outcomes for your enterprise, Cisco and our DNA approach is built on three design principles.

  • Services-centric to give enterprises the freedom to run services and applications when, where, and how they want it across the WAN and branch. Outcome: Faster service delivery.
  • Software-driven by virtualizing and optimizing applications and network functions for effective deployment on any platform: physic, virtual, or a mix of both. Outcome: Freedom of choice.
  • Automation of devices, apps and services for greater agility. Outcome: Less human errors.

Cisco DNA is the future of the network. These innovations allow you to reach greater network agility and achieve real business outcomes.

Antennas for Cisco Aironet Wi-Fi Access Points

In this article we will talk about the Antennas for Cisco Aironet Wi-Fi Access Points.

We know that Cisco Aironet 802.11n access points include the Cisco Aironet 1260 Series, 1600e Series, 2600e, 3500e Series, 3600e Series, and 1550 Series. These access points require the use of external antennas to make them fully functioning units. Cisco has developed antennas specifically designed for use with 802.11n access points to optimize performance.

Options for Every RF Environment

You can order Cisco Aironet 802.11n and 802.11ac access points with built-in antennas or with RF ports for connecting to external antennas. External antennas can improve your wireless coverage and data rates in certain situations. For example, building materials, floor layouts, distances, and usage patterns sometimes require concentrating radio signals in particular directions or at certain angles to get the fastest data throughput.

An extensive family of single-and dual-band antennas and mounting options for use with Cisco Aironet 802.11n and 802.11ac access points helps you optimize wireless performance in each unique situation (Table: Types of Available Wi-Fi AP Antennas* and Typical Uses). Indoors. Outdoors. Around corners. In open areas. Down hallways and mine shafts. And in places where aesthetics are important.

Types of Available Wi-Fi AP Antennas* and Typical Uses (See the Top Figure)

Benefits

• Improve wireless data throughput

• Match radio signal strength to desired coverage patterns and building layouts

• Manage performance of dualband implementations (5 GHz and 2.4 GHz) with full MIMO support

• Get the most out of your 802.11n and 802.11ac access point investments

Why Choose Cisco for your Wi-Fi AP antenna needs?

There are many good reasons for turning to Cisco for your Wi-Fi AP antenna needs:

• Cisco antennas go through complete electrical, mechanical, and environmental testing.

• All Cisco wireless network features are tested with Cisco antennas to help ensure consistent, repeatable performance. Examples of these wireless features are the Cisco radio resource management (RRM), Cisco CleanAir, rogue access point detection, and location services.

• Cisco antenna patterns are integrated with Cisco management and location systems.

May 17 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Switches - Cisco Firewall, #Cisco & Cisco Network

Cisco Catalyst 2960-X/XR switches, the greenest Cisco Catalyst access switches

Cisco Catalyst 2960-X/XR switches, the greenest Cisco Catalyst access switches

Why Select Cisco Catalyst 2960-X? What Benefits will you get from migrating to Cisco Catalyst 2960-X/XR series? We talked about the Cisco Catalyst 2960-X a lot before, such as the added features of Catalyst 2960-X Series, stacking of the Cisco Catalyst 2960-X and 2960-XR, Comparison of Cisco Catalyst 2960 Switches, etc. As the greenest Cisco Catalyst access switches, Cisco Catalyst 2960-X/XR switches are the best replacement for the 2960-S series.

The Cisco Catalyst 2960-X models provide Layer 2 switching and have one fixed power supply with an external redundant power supply. They provide 24 or 48 Gigabit Ethernet wire rate ports, PoE/PoE+ support, and four 1G Small Form-Factor Pluggable (SFP) or two 10G SFP+ uplinks.

With FlexStack-Plus technology, the Cisco Catalyst 2960-X switches can be stacked up to 8 members with up to 80 Gbps stacking capacity for high scalability.

In this article we will continue to talk about the architecture, Energy Efficiency of the Cisco Catalyst 2960-X and 2960-XR Series Switches.

Energy Efficiency

Catalyst 2960-X Series introduced new innovative energy saving modes for the switch.

● The Switch Hibernation Mode puts the switch to sleep when the switch is not in use. This feature enables the switch to save up to 90% of power during non-business hours.

● Downlink Hibernation Mode powers down the PHY and the optics of the downlink port when not in use.

● Energy Efficient Ethernet (EEE) enables dynamic power savings on all switch ports; saves about 15W for a 48port-switch and 8W for a 24 port-switch.

● EnergyWise Puts IP End Points in Energy Saver mode, saving 60%+ power with non-active IP devices.

The collective power savings with different energy efficient technologies will reduce the power consumption by up to 80%.

Downlink Hibernation Mode (DHM) feature enables all 2960-X switches to save power on the downlink ports. The switch supports static downlink port power-down where only the PHY and Optics are powered down when not in use.

When the switch is not in use, switch hibernation mode can be scheduled to save power. When the switch is in hibernation mode, it powers off application-specific integrated circuits (ASICs), and connected PoE devices. Power to most of the components is off. The DRAM is in refresh mode, keeping data intact. The switch hibernation mode is integrated with EnergyWise.

Q. Is a Cisco Catalyst 2960-X Series Switch usable while in hibernation mode?

A. No. All hardware components on the data path are switched off on Cisco Catalyst 2960-X Series Switches during hibernation mode.

The Cisco Catalyst 2960-X Series provides the following wake-up triggers from switch hibernation mode:

● Wake on scheduled real-time clock alarm/trigger

● Wake on mode button trigger

Q. Can Cisco Catalyst 2960-X Series Switches be scheduled to switch hibernation mode using the Cisco EnergyWise management tool?

A. Yes, the switch hibernation mode is integrated with Cisco EnergyWise. Cisco Catalyst 2960-X Series Switches can be put to switch hibernation mode using a Cisco EnergyWise management tool like any other IP devices.

Q. Is it possible to wakeup a Cisco Catalyst 2960-X Series Switch in switch hibernation mode before the scheduled wake-up time?

A. Yes, the mode button trigger will get the Cisco Catalyst 2960-X Series Switch out of switch hibernation mode.

Q. Can we schedule switch hibernation mode for some members only in a stack of Cisco Catalyst 2960-X Series Switches?

A. No. The whole stack of Cisco Catalyst 2960-X Series Switches can only be scheduled to switch hibernation mode.

Q. How long does it take for a Cisco Catalyst 2960-X Series Switch to be operational when it wakes up from switch hibernation mode?

A. A Cisco Catalyst 2960-X Series Switch coming out of switch hibernation mode is similar to a switch booting from reload. If the switches are stacked, master reelection is triggered after wake-up.

Q. Is Energy-Efficient Ethernet (EEE) 802.3az supported on the Cisco Catalyst 2960-X Series?

A. Yes, Energy-Efficient Ethernet (EEE) is supported on all downlink ports of the Cisco Catalyst 2960-X Series.

Q. Do we need to enable EEE on the Cisco Catalyst 2960-X Series?

A. EEE is enabled by default on all the downlink ports of the Cisco Catalyst 2960-X Series. If needed, EEE can be disabled.

Q. How is power saved with EEE on the Cisco Catalyst 2960-X Series?

A. Cisco Catalyst 2960-X downlink ports switch to low-power idle (LPI) mode during gaps in the data stream, saving power.

Q. Do both sides of the Ethernet interface have to support EEE for it to work?

A. Yes. Both endpoints of the Ethernet link must support EEE to get the power-saving advantages.

Q. How do I check if EEE is working?

A. The show eee status interface Gigabit Ethernet xxx” command can be used to check if EEE is agreed between both the endpoints.

The Cisco Catalyst 2960-X Series provides two types of console ports and one out-of-band Ethernet port:

● USB Type B console port

● Standard RJ-45 serial port

● 10/100 Ethernet management port

Q. Can both USB Type B console and RJ-45 console ports be used simultaneously?

A. No. Only one can be used for input, but both can receive output. When the USB console is connected, “it is used for input (by default)”. This design allows the administrator to see when the USB console port is in use. This capability is useful for remote administrators.

Q. Does the switch support auto-baud on the console port?

A. No. This was a tradeoff between console speed sensing and the ability to use the USB console.

Switch Architecture

Q. What management ports are available?

A. The Cisco Catalyst 2960-X Series provides two types of console ports and one out-of-band Ethernet port:

● USB Type B console port

● Standard RJ-45 serial port

● 10/100 Ethernet management port

Q. Can both USB Type B console and RJ-45 console ports be used simultaneously?

A. No. Only one can be used for input, but both can receive output. When the USB console is connected, “it is used for input (by default)”. This design allows the administrator to see when the USB console port is in use. This capability is useful for remote administrators.

Q. Does the switch support auto-baud on the console port?

A. No. This was a tradeoff between console speed sensing and the ability to use the USB console.

Q. Which management port has priority?

A. The RJ-45 console port is always the default management port, but when a PC is connected to the USB console port, the USB console takes over. The RJ-45 port continues to receive the output (a copy) of everything that gets displayed on the USB console port. This capability allows remote administrators to continue monitoring or logging the output showing what is happening at the switch location, sending it to a storage device.

Q. When a PC is left unattended on the USB console port, would remote administrators get locked out from the RJ-45 management port?

A. The USB console port has a default activity timer that can also be programmed by the user. This activity timer will expire and return control to the RJ-45 management port to avoid locking the remote administrator out.

Q. What can I do with the USB Type A port of the Cisco Catalyst 2960-X Series?

A. It is used to connect to an external USB memory drive for additional storage. This USB port can be used to perform software upgrades, store configurations, and even write memory core dumps for troubleshooting purposes. All Cisco USB memory drives can be used. Currently up to 8-GB USB drives are supported.

Q. Can a third-party USB Flash drive be used with the Cisco Catalyst 2960-X Series?

A. Yes, a third-party USB Flash drive can be used with the Cisco Catalyst 2960-X Series. They will work, but are not officially supported.

Q. What is the performance of the Cisco Catalyst 2960-X Series Switches?

A. The Cisco Catalyst 2960-X Series have a nonblocking switching architecture capable of forwarding traffic for all 48 1 Gigabit ports plus 2 10 Gigabit ports at line rate. See the datasheet for the MPPS information for each model.

Q. Do the Cisco Catalyst 2960-X Series Switches consume less power than the Cisco Catalyst 2960-S Series Switches?

A. The Cisco Catalyst 2960-X Series are based on the same building blocks as the 2960-S-Series Switches for most components. However, these switches have a new thermal design, new highly efficient power supplies, and new efficient fans, which use less power.

The Digital Network Architecture (DNA) building blocks and their programmable interfaces.

Watch this video for an overview on Cisco Digital Network Architecture.

Raakhee Mistry (Marketing Manager, has been with Cisco for over 12 years, serving in product management, partner program and solutions marketing roles.) collected the different audiences’ responses to Cisco Digital Network Architecture. She pointed out: Analysts agree that Cisco DNA is a Game Changer. Yes. The New Cisco DNA is a Game Changer for the Digital Era.

Cisco DNA is short for Digital Network Architecture. The Cisco Digital Network Architecture is a platform that will give our customers both a roadmap to digitization and a path to recognize immediate benefits of network automation, assurance and security. Cisco released it at Cisco Partner Summit 2016.

Cisco DNA complements Cisco’s market leading, data center based Application Centric Infrastructure (ACI) technology by extending the policy driven approach and software strategy throughout the entire network: from campus to branch, wired to wireless, core to edge.

Cisco DNA is delivered within the Cisco ONE Software family, enabling simplified software-based licensing, and helping with investment protection and flexibility.

The IT networking industry continues to demand knowledgeable professionals to help manage, secure and optimize their network infrastructure. Networking jobs can be found worldwide in exciting industries such as fashion, sports, and entertainment. Research indicates that a certification is second only to a four year college degree as a way to qualify people for positions and certifications were rated to be the top criteria in being able to determine an applicant's qualifications.

Cisco Digital Network Architecture Benefits

  • Insights. The network touches all things digital – users, devices, applications, sensors and cloud – and networking professionals are in a unique position to help their organizations capture insights in real time that allows businesses to make better decisions instantly and deliver better experiences.
  • Automation. This area is centered on IT speed and simplicity. Today’s networking professionals are CLI jockeys, but that will offer less value as time goes on. The network is evolving to software with software-defined networking, open APIs, network function virtualization and more. These new technologies provide networking IT with unprecedented agility that helps IT deliver business requirements faster and can free up cycles to support more strategic projects for their organization.
  • Security. While digital technologies have opened up new opportunities, they have also introduced a level of risk. As we see the proliferation of mobile devices and cloud adoption, the network perimeter is evolving and the attack surface has the potential to grow significantly. To combat that risk, networking professionals will be able to offer the business a new approach to inject security pervasively through the network, which can be the sensor and enforcer of security threats.

About Cisco IP Phone Registration & Boot Up

April 1 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco IP Phones, #Cisco & Cisco Network

CISCO IP Phone Boot UP Process

CISCO IP Phone Boot UP Process

Do you know the Cisco IP Phone Registration, Boot UP Sequence and related issues? Someone shared the main issues of IP Phone, SCCP & SIP Phone Registration Process with CUCM before. In this article we will talk something about the IP PHONE REGISTRATION ISSUES.

Firstly, let’s understand what Cisco IP Phone Registration & Boot UP Sequence are.

Step 1: Phone Loads Software (Image) and Starts the Configuration Process

Step 2: a. Phone Sends DHCP Request

b. DHCP Server Sends DHCP Response

Step 3: a. Phone Sends TFTP Request for a Configuration File

b. TFTP Server Sends the Default Configuration File

Step 4: a. TFTP Server Sends the Specific Configuration File of the Phone

b. Phone Registration Finishes

FIRST UNDERSTAND THE BOOTUP PROCESS, START TROUBLESHOOTING ACCORDING:

General Troubleshooting Sequence:

  • Disable DHCP and DNS to Test a Phone
  • Check for the Incorrect MAC Address on the Phone Label
  • Cisco CallManager and TFTP Services Do Not Run
  • Delete and Recreate a Phone
  • Understand a Network Trace File
  • Use Performance Monitor to Analyze Phone Activity
  • Manually Configure the IP Parameters on a 12 SP+ or 30 VIP Phone
  • Add Phones to Cisco CallManager
  • Enable, Configure, and Disable Auto−Registration
  • Manual Registration (Add an IP Phone Manually) etc....

THESE ISSUES COULD BE THERE:

  1. IP Phone Registration Toggles between Primary and Secondary CallManagers.
  2. Registration Rejected
  3. Cisco IP Phones Not Registered But seems to be working fine.
  4. Cisco IP Phones Take Too Long to Register.
  5. Cisco IP Phone Always Get Registered to the Publisher Server.
  6. Get "version error" on the Cisco IP Phone screen When Try to Register.
  7. Cisco phones causing excessive DHCP requests.

See the Figure"CISCO IP Phone Boot UP Process" above

Step 1: Phone Loads Software (Image) and Starts the Configuration Process:

During this step, these issues could be there,

* Registration with a Cisco CallManager server is successful only when the server adds the phone or when the server has Auto−Registration enabled. (The default for Auto−Registration is disabled.)

* Note: If the phone LCD screen does not light up, you could have a faulty phone. The phone also could be faulty if the message the phone displays never changes after you plug in the phone. Contact Cisco Technical Support to request a replacement if your phone is under warranty.

* If your phones do not use DHCP, see the Step 3a: Phone Sends TFTP Request for a Configuration File section of this document.

Step 2:

a). Phone Sends DHCP Request:

During this step, these issues could be there,

For Cisco 7940 and 7960: (to manually enable the DHCP Parameter on the phone itself):

Complete these steps on the Cisco 7940 and 7960:

1. Choose Settings.

2. Choose 3 (Network).

Scroll down to the DHCP Enabled parameter.

The selection must be Yes.

__________

Complete these steps on the Cisco 7910:

1. Choose Settings.

2. Choose 6 (Network).

3. Scroll down to the DHCP Enabled parameter.

The selection must be Yes.

__________

Cisco 12 SP+ and 30 VIP

Complete these steps on the Cisco 12 SP+ and 30 VIP:

1. Enter **#.

2. Enter 1.

3. Set all parameters to zero (0).

Note: Cisco 7910G supports only 10 MB speed, but 7910G+SW supports 10/100. If you have a 7910G, be sure to set the switch port that connects to the phone to 10 MB or Auto.

Any IP parameters that you have hard coded on the phones override the parameters that the DHCP server provides. In particular, the Alternate TFTP Server option overrides the TFTP server IP address that the DHCP provides. For information on how to reset your phone configuration to the original factory defaults, refer to either of these documents:

¨ Resetting 7900 Series IP Phones to Factory Defaults

b). DHCP Server Sends DHCP Response:

The DHCP response contains the phone IP address and the IP address of the TFTP server (which is usually a Cisco CallManager server). The response can also contain any of or all these common options:

· IP address of the default router (gateway)

· IP address of the Domain Name System (DNS) server

· Domain name includes option 150 for the TFTP server.

Step 3:

a). Phone Sends TFTP Request for a Configuration File:

  • The phone requests a specific configuration file. The name for this file is SEPMAC−Address.cnf. For example, the file name for a phone with the MAC address 0030.94C2.D5CA is SEP003094C2D5CA.cnf. If the file exists on the Cisco CallManager server, see the Step 4a: TFTP Server Sends the Specific Configuration File of the Phone section of this document.
  • If the phone is not in the Cisco CallManager database, the request for the specific configuration file results in a TFTP File Not Found response from the TFTP server. The phone then requests the file with the name SEPDEFAULT.cnf. If you have configured the Cisco CallManager server for Auto−Registration, this file exists and the server sends it to the phone. See the Step 3b: TFTP Server Sends the Default Configuration File section of this document.

Otherwise, the TFTP server of the Cisco CallManager server sends another File Not Found TFTP response. At this point, the phone restarts the configuration process.

b). TFTP Server Sends the Default Configuration File:

Note: This step only occurs if you have enabled Auto−Registration and the phone has not already registered

with the Cisco CallManager server.

If you have configured the Cisco CallManager server for Auto−Registration, it sends the SEPDEFAULT.cnf

file in response to the phone request. After the Cisco CallManager server database adds a phone by Auto−Registration, the phone has a SEPMAC−Address.cnf file. It does not reference the SEPDEFAULT.cnf

again.

Step 4:

a). TFTP Server Sends the Specific Configuration File of the Phone:

Note: This step only takes place if the phone creation occurred on the Cisco CallManager server. The configuration file contains several parameters for the phone. These include the device pool, the Cisco CallManager servers to use, configured speed dials, and other parameters. In general, any time you make a change in Cisco CallManager that requires the phone (device) to be reset, you have made a change to the phone configuration file.

b). Phone Registration Finishes:

The Cisco CallManager server sends the phone additional configuration elements during the final phases of the registration process.

In general, the registration process must complete successfully if the process goes this far.

To learn what takes place at this point, you need to set up a network analyzer to capture the IP packets that the phone sends to and receives from the server.

FACTS:

7961G Phone does not Register until it is Configured as a 7961>

IP phones CP−7961 and CP−7961G are basically the same platform. The G stands for global use that supports all languages.

So when you add a 7961G phone, you should add it as a regular 7961 phone. CP−7961G−GE is another IP phone with two gigabit Ethernet ports (10/100/1000).

If IP phone 7961G is added as 7961G−GE, it does not register with Cisco CallManager.

TASKS TO PERFORM:

Disable DHCP and DNS to Test a Phone

Check for the Incorrect MAC Address on the Phone Label

Cisco CallManager and TFTP Services Do Not Run

Delete and Recreate a Phone

Understand a Network Trace File

Use Network Monitor to Analyze Phone Activity

By default, Cisco phones are DHCP−enabled. If you do not use DHCP, you need to disable DHCP on the phone and manually assign the phone an IP address. In order to disable DHCP on a phone, use the phone keypad to program the phone IP address and other network addresses.

Enable, Configure, and Disable Auto−Registration

Manual Registration (Add an IP Phone Manually)

Note: If you have your Cisco CallManager servers set up in a cluster, every server has the configuration files for every phone that is in the Publisher database. Therefore, any Cisco CallManager server can serve as a TFTP server for the phones. The device pools to which you have assigned the phones determine the server with which the phones register. A phone can obtain the configuration file from a different server than the server with which the phone registers.

Using DHCP and DHCP Option 82

March 30 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco & Cisco Network, #Cisco Technology - IT News

DHCP Option 82 Operation

DHCP Option 82 Operation

DHCP is short for Dynamic Host Configuration Protocol. We know that DHCP is used in LAN environments to dynamically assign host IP addresses from a centralized server, which reduces the overhead of administrating IP addresses.

I’ve read an article “DHCP Snooping and DHCP Snooping Configuration” that is about a CCIE’s experience. In that article it also shares the DHCP Option 82 concept.

In this article we will share some info of using the DHCP Option 82.

DHCP also helps conserve limited IP address space because IP addresses no longer need to be permanently assigned to client devices; only those client devices that are connected to the network require IP addresses. The DHCP relay agent information feature (option 82) enables the DHCP relay agent (Catalyst switch) to include information about itself and the attached client when forwarding

DHCP requests from a DHCP client to a DHCP server. This basically extends the standard DHCP process by tagging the request with the information regarding the location of the requestor. (See the Figure “DHCP Option 82 Operation”)

...

The following are key elements required to support the DHCP option 82 feature:

• Clients supporting DHCP

• Relay agents supporting option 82

• DHCP server supporting option 82

The relay agent information option is inserted by the DHCP relay agent when forwarding the client-initiated DHCP request packets to a DHCP server. The servers recognizing the relay agent information option may use the information to assign IP addresses and to implement policies such as restricting the number of IP addresses that can be assigned to a single circuit ID. The circuit ID in relay agent option 82 contains information identifying the port location on which the request is arriving.

Note:

1. The DHCP option 82 feature is supported only when DHCP snooping is globally enabled and on the VLANs to which subscriber devices using this feature are assigned.

2. DHCP and the DHCP option 82 feature have not been validated in the lab for EttF version 1.1. At this time, Cisco recommends considering only DHCP with option 82 for the application servers at level 3.
