Changing the hostnames on all switches on network with NCM

$

Hi Guys (and Gals),

 

Due to a recent change in our network we need to rename all of our cisco switches with a new naming convention.  Our current convention goes like this:

c12-001

c12-002

c12-003

...

c12-254

 

This is spread across the whole campus so new switches have more recent numbers, but can be located in ANY building.  So we have decided to change the naming convention so we know where a switch is based on the hostname.

So the new convention goes something like this:

BA45-001

BA45-002 - All for building A

BA45-003

----

BG150-001

BG150-002 - All for building G

BG150-003

 

The numbers represent the final two octets of the IP address of the switch, the first two are predefined. So for example BA45-001 has an IP of 10.15.45.1 and BG150-003 would have a IP of 10.15.150.3

 

At the moment I have to rename them manually and after about an hour change the IP address, this is because it takes a while for the hostname to update on the system.

Is there an easier way to do this?

 

Thank you,
