Cisco 1900s, fru, AS5300s and AS5400s...

[Andre van der Merwe]

Hi

NOTE:
This is for -test- purpose only please don't patch your
live systems...

We have added the following to the version RANCID (2.3.1) we run.

 - fru / product code support
 - 1900 improved support, (I hope :) )
 - Cisco AS5300, AS5400 basic "Slot" support

FRU/product code.

The additional field within the "Slot" field has been added and called
"fru" for now, this is the product "fru" code. The ability for 
RANCID to pick this up is based on the IOS you run and the age 
of the PA/NM cards. As usual Cisco does not have a standard way of 
doing this, so there a bit of kludging to make it work. 

Here is the "fru" field as shown in the sample below.

Here is the basic mod to "rancid" to get it all in.

--------

The other thing we have done is hopefully improve the Cat 1900 support by adding
some pager handling stuff to clogin, we are now able to use RANCID collect       
configs from our group of 1900's they don't support "term length 0" as far as I can
see.

Here is the basic mod to "clogin".

>               #
--------         

Hope this helps.
