More about Cisco 10GbE Optics Modules

October 16 2014 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Modules - Cisco Cables - Cisco Memory

There have been numerous different form factors and optics types introduced over the past years. The oldest, XENPAKs, remain very popular as the install base is large, while the newest SFP+ offer a much smaller form factor and the ability to offer 1G/10G combo ports on hardware for the first time. Like the move from GBIC to SFP the move from XENPAK to SFP+ seems inevitable, but currently there are several types of standard modules/form-factors available. In the following part there is a guide to these main module types and optical standards currently available.

XENPAK-the original 10GbE pluggable optics. Presents SC connectors

X2-the successor to the XENPAK. Presents SC connectors

XFP-the first of the small form factor 10GbE optics. Presents LC connectors

GBIC-the hot-swappable Gigabit Interface optical module with SC connector

SFP-also called mini-GBIC, is upgraded version of GBIC transceiver

SFP+-a 10GbE optics using the same physical form factor as a gigabit SFP. Because of this, many of the small SFP+ based 10GbE switches use 1G/10G ports, giving an added degree of flexibility. Presents LC connectors

Within these form factors are many different types of optical and electrical specifications; the only requirement is that the optics type match. It is perfectly acceptable to connect an X2 to an SFP, or a XENPAK to an SFP+, or any other combination.


Optical Standards


CX4 modules use Infiniband 4X cabling, and have a maximum distance of 15 meters. CX4 is an early copper standard, and due to the physical size of the connector, is not available in SFP+ form, or in XFP form from Cisco (Dell Networking, though, offers a CX4 XFP). CX4 was designed as a drop-in replacement for legacy Infiniband switching hardware – the existing Infiniband cable plant can be reused in a CX4 based network.

10GBase-CX1 is the SFP+ copper standard. The standard has a maximum distance of 10 meters, though Cisco currently only offers lengths up to 5m. This is actually a cable with SFP+ ends, not a module with a separate cable.

Here is a picture


Notice that the cable is permanently integrated into the SFP+ ends. Because of this, both devices must present SFP+ ports. While the cables are somewhat inconvenient to work with due to the integration, CX1 modules are used due to a very low cost, extremely low power consumption (0.25W per cable), and a negligible latency penalty.


Multimode Fiber

10GBase-SR is the original multimode optics specification, and is still by far the most commonly used. As it uses a single, low cost solid state laser assembly, it is also the least expensive of the optical modules available for a 10GbE platform. However, 10GBase-SR is very sensitive to fiber type. Below is a list of cable specs and maximum distance with SR optics.

Core Size

Modal Bandwidth






This is standard multimode fiber.
















AKA: OM3 or 10GbE-optimized fiber


Because of this, it is highly recommended that any new deployment of multimode fiber be done with OM3 fiber. This will ensure an easier transition to 10GbE for future needs.

To overcome the distance limitations of SR optics, the 10GBase-LX4 standard was developed. LX4 uses 4 lasers, each operating at a different wavelength, at a 2.5Gbps data rate. This results in a range of 240-300 meters, depending on cable grade. However, due to the complex laser assembly, it is not possible to get LX4 optics in XFP or SFP+ versions. With the ready availability of OM3 fiber and newer standards that provide long reach over multimode with a single laser, LX4 is rapidly becoming obsolete.

The replacement to LX4, 10GBase-LRM will reach up to 220m over standard multimode fiber, but without the complexity of the LX4 optics. Instead, a single laser operating at 1310nm is used. This allows LRM optics to be packaged in XFP and SFP+ form factors.


Singlemode Fiber

10GBase-LR can reach up to 10km over singlemode fiber. There is no minimum distance for LR, either, so it is suitable for short connections over singlemode fiber as well.

10GBase-ER can reach up to 40km over singlemode fiber. Due to the laser power, attenuation is required for links less than 20km long.

ZR optics can reach up to 80km over singlemode fiber. Due to the very high transmit power, significant attenuation is needed for shorter links. Use of ZR optics should be preceded with an optical power test of the fiber span in question to ensure a problem-free deployment. Interestingly, 10GBase-ZR is actually not an IEEE standard, though most vendors offer a ZR option.

10GBase-LW optics use the same laser, and have the same specifications as the 10GBase-LR optics. However, the LW optics present SONET/SDH physical signaling, allowing LW-equipped devices to interface directly with an existing OC192 transport infrastructure. LW optics are only available in XENPAK and X2 form factors. XFP-based cards move this functionality from the transceiver to the card itself, so make sure that if this functionality is needed, that the card itself has this support. The primary example is the as in the SPA-1X10GE-L-V2 vs the SPA-1X10GE-LW-V2.

10G over DWDM
With 10GbE, it is possible to get optics modules that output at DWDM wavelengths, allowing for much simpler DWDM deployments, and with these optics no additional transponder hardware is required. Current innovations in 10GbE/DWDM optics include full C-band tunability for ease of sparing, ordering, and provisioning of DWDM channels, as well as features like forward error correction (FEC) and OTN/G.709 support integrated directly onto the optic.


More about Cisco SFP, SFP+ Purchasing

Being used and interchanged on a wide variety of Cisco products, the hot Cisco SFPs can meet Cisco users’ different needs, for example, GLC-SX-MM, The 1000BASE-SX SFP, can support up to 1km over laser-optimized 50 μm multimode fiber cable; GLC-LH-SM, Cisco 1000BASE-LX/LH SFP transceiver module, operates on standard single-mode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers; GLC-T over unshielded twisted pair (UTP) Category 5 Cable, etc. And module numbers, such as SFP-10G-SR, GLC-ZX-SM, SFP-GE-T, GLC-BX-D and so on. Cisco SFP+, the 10G fiber optical module, can connect with other type of 10G modules.  The popular SFP+ modules, for instance, SFP-10G-SR, used for high-speed data transmission applications, supports 300m by MMF; SFP-10G-LRM supports 220m on standard FDDI grade multimode fiber (MMF) and 300m on standard single-mode fiber (SMF, G.652); SFP-10G-LR, supports 10 km on standard single-mode fiber (SMF, G.652).

Cisco ACI Mode

October 8 2014 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Switches - Cisco Firewall

The Nexus 9000 family of switches will operate in one of two modes:

NXOS Mode–If you’ve worked with Cisco’s DC switches like the Nexus 7K or 5K, this should be very familiar to you. In this mode, you essentially have a 10GbE or 40GbE switch, with the features that are baked into that

In NXOS Mode, all of the additional custom ASICs that are present on the switch fabric are used primarily for enhancing the functionality of the merchant silicon platform, such as increasing buffer space, etc.

ACI Mode–This is a completely different mode of operation for the Nexus 9000 switch. In this mode, the switch participates in a leaf-spine based architecture that is purely driven by application policy. It is in this mode that we are able to define application relationships, and imprint them onto the fabric.


ACI is meant to provide that translation service between apps and the network.


As mentioned before, also pointed out in the article Cisco Nexus 9000 Series Switches Overview, the second mode that the Nexus 9000 series operates in, is ACI mode. This mode allows for enhanced programmability across a complete fabric of Nexus 9000 switches. With ACI as the SDN solution on top, the fabric acts like one big switch–forwarding traffic using a myriad of policies that you can configure.

  • 1/10G Access & 10/40G Aggregation (ACI)

48 1/10G-T & 4 40G QSFP+ (non blocking)–meant to replace end-of-rack 6500’s

36 40G QSFP+ (1.5:1 oversubscribed)–used as a leaf switch, think end of rack

  • 40G Fabric Spine (ACI)

36 40G QSFP+ for Spine deployments (non blocking, ACI only)

1,152 10G ports per switch

  • 36 spine ports x 8 line cards=288 leaf switches per spine
  • Leaf switches require 40G links to the spine


The line cards that support ACI will not be released until next year.

Spine line cards

  • 36x 40G ports per line card and no blocking

Supervisor Modules

  • Redundant half-width supervisor engine
  • Common for 4, 8 and 16 slot chassis (9504, 9508, and 9516)
  • Sandy bridge quad core 1.8 GHz
  • 16GB RAM
  • 64GB SSD

System controllers

  • Offloads supervisor from switch device management tasks
  • Increased system resilience & scale
  • Dual core ARM 1.3GHz
  • EoBC switch between Sups and line cards
  • Power supplies via SMB (system management bus)

Fabric Extenders

  • Supports 2248TP, 2248TP-E, 2232PP-10G, 2232TM-10G , B22-HP, B22-Dell

Cisco IP Phone: Exit Softkey does not Terminate Visual Voicemail Midlet

September 23 2014 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco IP Phones

In this document it describes the current design and the problems with Visual Voicemail (when the phone is subscribed with Voicemail and Visual Voicemail) and offers a solution.



The application remains in the memory of the phone when you press the Exit softkey in Visual Voicemail. Therefore, when you press the Messages button, the phone displays the Visual Voicemail quickly. You can see the Visual Voicemail icon on the top left side of the screen.

See Additional User Information section in the Installation and Configuration Guide for Visual Voicemail


Complete these steps to reproduce the issue when the phone is subscribed with Voicemail and Visual Voicemail:

  1. Press the Messages button.
  2. Choose Visual Voicemail service between Voicemail (Standard TUI interface) and Visual Voicemail service.
  3. From the Sign In screen, press the Exit softkey before you sign in.
  4. Press the Messages button.
  5. The Sign In Screen is displayed instead of the Service Selection screen.


This particular issue is also seen when you log in to Visual Voicemail Service and use the Exit softkey.


This issue is seen on Skinny Call Control Protocol (SCCP) phones. Ideally the Exit softkey should teminate the application. The Visual Voicemail service will be terminated if the Messages button is used instead of the Exit SoftKey and both the options are presented when the Messages button is pressed again.


In the case of 99xx series phones, it shows both options even when the Exit softkey is used.



Complete these steps in order to resolve this issue:

  1. Add a new parameter in the Visual Voicemail service configured on Cisco Unified Communications Manager (CUCM).
  2. Name it as unload_midlet_on_exit and set it to 1.
  3. Resubscribe the phones to this service.
  4. Reset the phones.

Note: This might take a few minutes to load the service.

How to Activate Demo License on a Cisco 880 Router?

September 18 2014 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco License

If you have a Cisco router 880 series with an advsecurity license but you find out your unable to use some protocols which you like to use. How to do that? In the following example that a Cisco 880 user shared here, and it told you how to activate Demo License on a Cisco 880 router?

I found out that the Cisco router 881w had an demo license of the advipsecurty license.

router#sh license feature

Feature name      Enforcement  Evaluation  Clear Allowed  Enabled

advipservices         yes         yes           yes         no

advsecurity           no          no            yes         yes


Which wasn’t actived. But your able to activate this license due the following command.

router#license boot module c880-data level ?

advipservices     advipservices level

advsecurity       advsecurity level


If you select the advipservices you will need to reboot the router. after the reboot the advipservices is activate now you have time to buy the correct license SL-880-AIS (upgrade option) [ Cisco 880 Advanced IP Services Image Feature License ]

You can download either also a demo license via the following linkhttp://www.cisco.com/web/go/license/index.html you need a CCO account to get the demo license.


If you have the correct license activated than you will see the following output

router#sh license feature

Feature name      Enforcement  Evaluation  Clear Allowed  Enabled

advipservices         yes         yes          yes          yes

advsecurity           no          no           yes          no


Now you have to restart the router and your new license should be activated.

Cisco Catalyst 6500 Series VSS 1440

September 9 2014 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco & Cisco Network

VSS is network system virtualization technology that pools multiple Cisco Catalyst 6500 Series Switches into one virtual switch, increasing operational efficiency, boosting nonstop communications, and scaling system bandwidth capacity to 1.4 Tbps. Switches would operate as a single logical virtual switch called a virtual switching system 1440 (VSS1440). VSS formed by two Cisco Catalyst 6500 Series Switches with the Virtual Switching Supervisor 720-10GE

In a VSS, the data plane and switch fabric with capacity of 720 Gbps of supervisor engine in each chassis are active at the same time on both chassis, combining for an active 1400-Gbps switching capacity per VSS. Only one of the virtual switch members has the active control plane. Both chassis are kept in sync with the inter-chassis Stateful Switchover (SSO) mechanism along with Nonstop Forwarding (NSF) to provide nonstop communication even in the event of failure of one of the member supervisor engines or chassis. 


The Cisco Catalyst 6500 Series Virtual Switching System (VSS) 1440 allows for the merging of two physical Cisco Catalyst 6500 Series Switches together into a single, logically managed entity. The following figure graphically represents this concept where you can manage two Cisco Catalyst 6509 chassis as a single, 18-slot chassis after enabling Cisco Virtual Switching System.


The Cisco Catalyst 6500 Virtual Switching System (VSS) 1440 takes the flagship Catalyst 6500 platform to the next level with network system virtualization.

Virtual Switching System 1440 Redundancy State


Creating a VSS 1440

The key enabler of a VSS 1440 is the Virtual Switching Supervisor 720-10G. Any two Cisco Catalyst 6500 Series Switches with this supervisor engine can be pooled together into a VSS 1440*. The two switches are connected with 10 GbE links called Virtual Switch Links (VSLs). Once a VSS 1440 is created it acts as a single virtual Catalyst switch delivering the following benefits:

Operational Manageability

  • Two Catalyst 6500s share a single point of management, single gateway IP address, and single routing instance
  • Eliminates the dependence on First Hop Redundancy Protocols (FHRP) and Spanning Tree Protocol


Non-Stop Communications

  • Delivers deterministic, sub-200 millisecond layer 2 link recovery through inter-chassis stateful failovers and the predictable resilience of Etherchannel


Scales to 1.4 Tbps

  • Scales system bandwidth capacity to 1.4 Tbps by activating all available bandwidth across redundant Catalyst 6500 switches
  • Up to 132 ports of 10 GbE per system


What are the benefits of using VSS?

VSS offers superior benefits compared to traditional Layer 2/Layer 3 network design. VSS increases operational efficiency by simplifying the network, reducing switch management overhead by at least 50 percent. Single point of management, IP address, and routing instance,Single configuration file and node to manage and you won’t have to configure two switches with identical policies and other config. It eliminates the requirement for HSRP, VRRP or GLBP and you have to use just one IP address instead of three used with any FHRP.

Multi chassis Ether Channel (MEC) is a Layer 2 multipathing technology that creates simplified loop-free topologies, eliminating the dependency on Spanning Tree Protocol, which can still be activated to protect strictly against any user misconfiguration and with X2-10GB-ER 10 Gigabit Ethernet optics, the switches can be located up to 40 km apart.

Inter-chassis stateful failover results in no disruption to applications that rely on network state information (for example, forwarding table info, NetFlow, Network Address Translation [NAT], authentication, and authorization). VSS eliminates L2/L3 protocol reconvergence if a virtual switch member fails, resulting in deterministic subsecond virtual switch recovery.

By activating all available Layer 2 bandwidth across redundant Cisco Catalyst 6500 Series Switches with automatic, even load sharing. Link load sharing is optimized because it is based on more granular information, such as L2/L3/L4 parameters, unlike virtual LAN (VLAN)-based load balancing in Spanning Tree Protocol configuration.

Cisco Catalyst 4500-X 10GE Modular Switch Review

September 2 2014 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Switches - Cisco Firewall

Cisco Catalyst 4500-X Series Switches, the fixed 10GE aggregation switch, help you easily meet business growth objectives.

The Catalyst 4500-X series looks similar to the Cisco Nexus 5000 series switches, but actually it is definitely more of a campus LAN switch, rather than the Nexus data center line. There are two base configurations-a 16-port and a 32-port 10GE models. Each model has an expansion slot that currently supports an 8-port 10GE uplink model (Cisco datasheets suggest that a 40GE uplink module is on the roadmap).



Similar to the Nexus 5000s, the 4500-X ports support SFP+ 10GE optics along with 1GE SFP modules.The 4500-X supports both IPv4 and IPv6 routing in hardware, along with support for VRF-Lite and “Easy Virtual Network” (EVN) features. (The Nexus 5000s require an additional expansion module for layer 3 support).


VSS on Cisco 4500-X Series

The most intriguing feature in the 4500-X may be built-in VSS (“Virtual Switch System”) support. Two 4500-X switches can be linked by 10GE ports and configured as a single logical switch. This simplifies configuration while providing a higher level of availability. It also allows ether-channels to be be built across two switches (for link redundancy and performance while eliminating the need to build spanning-tree triangles). The VSS feature has previously been reserved for the 6500 chassis with Supervisor 720s. The 4500-X therefore offers a much more cost effective way to provide a highly available distribution layer (or even a core for smaller environments that want a 10GE backbone).



The Cisco 4500-X is an intriguing new solution as an aggregation switch for campus LANs that want to bring in 10GE uplinks without the cost or complexity of a chassis based switch. VSS capabilities in particularly allow for a dual switch redundant solution that logically functions as a single switch—a solution that up until now has required a much more expensive chassis based switch.

Cisco UCS 6324 Fabric Interconnect Review

August 11 2014 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco & Cisco Network

At the end of July, Cisco has quietly announced a new addition to the UCS family–a mini Fabric Interconnect, called the UCS 6324 Fabric Interconnect, which unlike the ones before it plugs directly into the UCS 5108 chassis. With connectivity for up to 15 servers (8 blade servers and up to 7 direct-connect rack servers), the Cisco 6324 is geared toward small environments.

“The 6324 FI is out! What amazing hardware! This is a whole UCS in a 5108 Chassis. Now what I wonder is if this is just code? Being able to take a single chassis and install proper code and have a stand-alone UCS would be GREAT. This will be “Cool” if it is a special chassis, but a GAME CHANGER if any chassis will do with code only (and maybe certain models of IOM’s that might be on hand anyhow).” Some Cisco fans said like that.

Appear’s a new IOM is needed to make this work in a 5108 Chassis.


Cisco introduces Cisco UCS 6324 Fabric Interconnect like that.

The Cisco UCS 6324 Fabric Interconnect is a 10 Gigabit Ethernet, FCoE, and Fibre Channel switch offering up to 500-Gbps throughput and up to four unified ports and one scalability port.

The Cisco UCS 6324 Fabric Interconnect extends the Cisco UCS architecture into environments with requirements for smaller domains. Providing the same unified server and networking capabilities as in the full-scale Cisco UCS solution, the Cisco UCS 6324 Fabric Interconnect embeds the connectivity within the Cisco UCS 5108 Blade Server Chassis to provide a smaller domain of up to 15 servers (8 blade servers and up to 7 direct-connect rack servers).


CISCO 6324 FI Overview


Each 6324 FI module contains:

  • 16 x 10GbE internal ports (2 per 1/2 width slot)
  • 4 x 10Gb SFP+ external uplink ports
  • 1 x 40Gb QSFP+ scalability port
  • 1 x 10/100/1000 Mbps Management port for out-of-band management

The 4 external uplink ports can be configured as 1/10 Gigabit Ethernet or 2/4/8-Gbps Fibre Channel ports.  The scalability port is designed to allow for connectivity to up to 4 x UCS rack servers with a post-release feature of also allowing a 2nd UCS 5108 chassis to interconnect.

The 6324 FI provides Layer 2 forwarding with support for:

  • VLAN trunks
  • IEEE 802.1Q VLAN encapsulation
  • Support for up to 512 VLANs and 32 virtual SANs (VSANs) per interconnect
  • Jumbo frames on all ports (up to 9216 bytes)
  • Link Aggregation Control Protocol (LACP): IEEE 802.3ad
  • Internet Group Management Protocol (IGMP) Versions 1, 2, and 3 snooping
  • Advanced EtherChannel hashing based on Layer 2, 3, and 4 information
  • Pause frames (IEEE 802.3x)
  • Layer 2 IEEE 802.1p (class of service [CoS])


It is also rumored that UPDATED–based on the information from UCSGuru (below) a new an updated UCS 5108 blade chassis will be coming out soon which will allow for heartbeat and cluster connectivity between the UCS 6324 FI modules inside a chassis as well as support for “dual voltage” power supplies. Is that real? We are looking forward to it.

Cisco UCS Fabric Interconnect Port Licensing

August 7 2014 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco License

When you are designing a Cisco UCS Unified Computing environment you will use several components which will work together. One key object in the whole chain is the Fabric Interconnect which connects the chassis, used storage and uplinks to Datacenter Switches like the Nexus 5000 series. Especially when designing a FlexPod Certified Design.


All chassis, blades and rack servers that are attached to the Fabric Interconnects are part of a single, highly available management domain. By supporting Unified Fabric, the Cisco UCS 6200 Series provides the flexibility to support LAN and SAN connectivity for all blades within its domain.

Typically deployed in redundant pairs, the Cisco UCS 6200 Series provides uniform access to both networks and storage. Which is great when building in our case a fully virtualized VMware environment.


Currently there are two types of Cisco UCS Fabric Interconnect switches, namely:
Cisco UCS 6248UP 48-Port 10 Gigabit Ethernet, FCoE and native Fibre Channel switch offering up to 960-Gbps throughput and up to 48 ports.
Cisco UCS 6296UP 96-Port 10 Gigabit Ethernet, FCoE and native Fibre Channel switch offering up to 1920-Gbps throughput and up to 96 ports.


The ports on a Fabric Interconnect needs to be licensed to be used. Any of the 32 fixed ports or expansion module ports can be used for 1G/10G Ethernet, FCoE or FC. To use a port you must have the correct SFP and configure the port as you like to use it via the Unified Ports tool.

  • On the 6248UP there are 12 ports pre-licensed and up to 20 additional ports can be licensed using an UCS-LIC-10GE license per port.
  • On the 6296UP there are 18 ports pre-licensed and up to 30 additional ports can be licensed using an UCS-LIC-10GE license per port.
  • The former Cisco Fabric Interconnect models UCS 6120XP has 8 ports pre-installed licenses and the UCS 6140XP has 16 pre-installed licenses.


More Tips: Some Users’ Real Problem like this: UCS 6248UP Licensing

How will the 6248UP Fabric Interconnect ports be licensed? Will ports configured as Fiber Channel also consume a port license? Will the Expansion Module be fully licensed or will it share license with fixed ports?

The UCS 6248UP (with NO expansion module) has 32 physical ports. Of these–12 ports are pre-licensed; Up to 20 additional ports can be licensed using UCS-LIC-10GE per port

The UCS-FI-E16UP (16 port Unified Expansion Module) has 16 physical ports. Of these–

  • 8 ports are pre-licensed
  • Up to 8 additional ports can be licensed using UCS-LIC-10GE per port

Can the UCS-FI-E16UP ports be used for chassis connections or are they for uplinks only (like the 6120/6140 GEM modules were)? Is a port license required for every use of a physical port? E.g.

  • 10GE chassis connection
  • 1/10GE uplink
  • 1/2/4/8 Gbps FibreChannel uplink
  • 10GE FCoE direct attach
  • 1/10GE appliance port
  • 1/10GE SPAN/monitor port

All physical port need to be licesned on the fabric interconnect. The 6200 license structure is listed above. The 6100s the fixed ports needed license however the expansion cards do not.

Expansion Module
The UCS-FI-E16UP (16 port Unified Expansion Module) has 16 physical ports. Of these 8 ports are pre-licensed and up to 8 additional ports can be licensed using UCS-LIC-10GE per port?

The eight default licenses that come with a 6200 series fabric interconnect expansion module can be used to enable ports on the base module, but will travel with the expansion module if it is removed. In the 6248Up there is room for 1 expansion module and in the 6296UP you can fit 3 expansion modules.

Important: All ports need to have licenses regardless if it is server/Ethernet/fiber channel ports!! You can manage licenses through UCS Manager.


Typical Questions from Users While Dealing with Cisco UCS Fabric Interconnect Port Licensing

Q: Can I export port licenses from the 6100 series to the 6200 series?

A: Licenses are not portable across product generations. Licenses purchased for 6100 series fabric interconnects cannot be used to enable ports on 6200 series fabric interconnects or vice-versa.


Q: Licenses brought to the Fabric Interconnect through an expansion module; do they keep the licenses when the expansion module is removed?

A: Upon removal of an expansion module, any default expansion module licenses being used by the base module are removed from the ports on the base module, resulting in unlicensed ports.


Q: If I use a license for a port and I disable the port later on is that license locked?

A: Port licenses are not bound to physical ports. When you disable a licensed port, that license is then retained for use with the next enabled port. If you want to use additional fixed ports, you must purchase and install licenses for those ports.


Q: If I need a new port quickly but I haven’t received the license file yet, what can I do?

A: If you attempt to use a port that does not have an installed license, Cisco UCS initiates a 120 day grace period. The grace period is measured from the first use of the port without a license and is paused when a valid license file is installed. The amount of time used in the grace period is retained by the system.


Q: When I use a port in Grace Period do I use it for all ports?

A: No, each physical port has its own grace period. Initiating the grace period on a single port does not initiate the grace period for all ports.
