GNS 3 and Cisco 1700,2600,7200 IOS in one pack

[http://www.gns3.net]

GNS3 is a graphical network simulator that allows you to design complex network topologies and to launch simulations on them.

To allow complete simulations, GNS3 is strongly linked with :

  • Dynamips, an IOS emulator which allows users to run IOS binary images from Cisco Systems.
  • Dynagen, a text-based front-end for Dynamips.
  • Pemu, a PIX emulator.

GNS3 is a excellent complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA, CCNP, CCIP or CCIE certifications.

It can also be used to experiment features of Cisco IOS or to check configurations that need to be deployed later on real routers. This project is an open source product that may be used on multiple platforms, including Windows, Linux, and MacOS X.

Features overview

  • Designing high quality complex network topologies.
  • Emulating Cisco routers and PIX firewalls.
  • Simulating simple Ethernet, ATM and Frame Relay switches.
  • Load and save in Dynagen’s INI-like format.
  • Image export (JPEG, PNG, BMP and XPM).

Download Cisco Unified Communications Manager 6.0.1 – Install DVD

Cisco Unified Communications Manager (CUCM), formerly Cisco Unified CallManager and Cisco CallManager (CCM), is a software based IP call agent platform sold by Cisco Systems. Cisco renamed the product to Unified Communications Manager. Version 6 was supposed to merge all features of the Linux appliance (SIP support and licensing requirements) between the Linux platform and Windows version. The released version of Unified Communications Manager will not support the Windows platform.

This version added an intercom feature between endpoints, and integrated Mobility Manager (single number reach to multiple destinations, IP Phone, Cell Phone, etc).

Cisco Switch Err-Disable problem

Yesterday, I found 3 FastEthernet port disabled on My Catalyst Express 500 (Port 20,23 & 24): ce-500

And this is the screen shoot from the alert page:

alert

Result of running ’#show interface status’; 3 port status =’err-dissabled’ port-status

VLAN Configuration; Port 23-24 on Default VLAN, Port 20 on VLAN 3 vlan-info

Taken from Forum, port with ’ERR-DISABLED’ status can be resolved by running ’shutdown’ and ’no shutdown’ on that interface:

——————————————————–

#config t

(config)#interface fastethernet 20

(config-if)#shutdown

(config-if)#no shutdown

In order to turn on errdisable recovery and choose the errdisable conditions, issue this command: #errdisable recovery cause ?

Another command to troubleshoot:

  • show interfaces status err-disabled-Shows which local ports are involved in the errdisabled state.
  • show etherchannel summary-Shows the current status of the EtherChannel.
  • show errdisable recovery-Shows the time period after which the interfaces are enabled for errdisable conditions.
  • show errdisable detect-Shows the reason for the errdisable status

Because ’err-disable’ on my port caused by LOOPBACK, and when I see from ’#show errdisable recovery’ command the timer status is disabled, so I need to ’enable’ and give recovery timer for loopback.

(config)#errdisable recovery cause loopback

(Config)#errdisable recovery interval 400

————————————————-

Cause I am not Certified yet on Cisco, I don’t know is it a good decision or not give recovery timer for ’loopback’. I just won’t t to run ’shutdown’ & ’no shutdown’ if my port status ’err-dissable’ again. maybe u can give suggestion? I’ll apreciate it..
