Putty is an extremely useful tool for telent and SSH access to Cisco routers.

Cisco License Keys

2009-08-20T10:06:00.002+01:00

This could be useful if you require in a hurry license keys for Cisco.

Select the following url

www.cisco.com/go/license

and enter you CCO login as far as I know if you have the correct privileges you will be able to aquire the necessary license keys. They will be emailed to your CCO email account. This is all part of the PAK process

Have not tried this in anger yet so would be interested to know how and if it works.

Cisco phones controlled by SIP

2009-08-18T13:31:00.008+01:00

Cisco IP phones registered with CUCM (Cisco Unified Communications Manager) are usually controlled using SCCP (Skinny Call Control Protocol).

Since CallManager v5.0 (now Communications Manager) it has also been possible to use SIP (Session Initiation Protocol) for IP phone control.

We are often asked when it would be desirable to use SIP instead of SCCP. This useful "Cisco Subnet" article explains when and why SIP could be the better option.

Read it here: Why would I use a Cisco 7900 phone on CUCM using SIP?

Enabling IPv6 on a Catalyst 3560

2009-07-17T09:00:00.003+01:00

The Catalyst 3560 Switch supports IPv6. but if you enter the normal ipv6 unicast-routing command nothing happens.
This is because you have to enable the Switch Database Management (SDM) template on the Catalyst 3560 to support both ipv4 and ipv6. so the commands are

sdm prefer dual-ipv4-and-ipv6 default
reload <---- don't forget to reload
ipv6 unicast routing.

Now everything is just the same as any other ipv6 router

The Dude

2009-07-16T23:58:00.001+01:00

I was looking for a cheap SNMP network monitoring tool and came across "The Dude" network monitor. Its a new application by MikroTik It will automatically scan all devices within specified subnets, draw and layout a map of your networks, monitor services of your devices and alert you in case some service has problems and best of all it's free. Check it out at http://www.mikrotik.com/thedude.php

Cisco ASA NetFlow Support

2009-07-16T20:23:00.005+01:00

Only Cisco IOS Routers supported NetFlow in the past. NetFlow was only supported on Cisco ASA 5580 with software version 8.1. With the introduction of Cisco ASA software version 8.2, NetFlow is now supported on ALL ASA Models. This new feature on ASA is called NetFlow Security Event Logging (NSEL).

Get some BGP regex practice

2009-07-16T19:24:00.003+01:00

If you want to test your regular expression skills you can use the show ip bgp regex command .

But you dont have a router with a big enough bgp table. then use one of the number of route servers out on the internet like this one telnet://route-server.ip.tiscali.net/

Try this command show ip bgp regexp _174_ to see all the routes that have traversed AS 174 for example.

Testing IP connectivity with a switch macro command

2009-07-16T19:13:00.004+01:00

Use the Cisco switch IOS macro command to create a IP connectivity tester.
Create a macro like the one below the name "ctest" is just an example, call it what you like

macro name ctest
do ping 172.16.56.1
do ping 172.16.43.1
do ping 172.16.34.1
do ping 172.16.13.1
@

Then all you need to do is run the macro in global configuration mode, easy

macro global apply ctest

Verify using the | extension

2009-07-16T10:40:00.004+01:00

Verify your configuration using show commands with the "" extension

Try these on a router

Show frame-relay pvc include STAT
show run begin ^ro
Sh run section interface fastethernet 0/0

Or on a switch

Show interface status exclude _1_

Try them and see what they do and think of your own
Its also a good way for you to practice your regular expressions
Remember anything after the is case sensitive
