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.
