> All,
> 	As I progress with our new install of Rancid version 2.3.6 I am taking a close look at how the xrrancid script handles CRS-1 routers running IOS-XR. We have single and multi-chassis CSR-1 systems currently running IOS-XR 3.9. What I am seeing is that some of the commands syntax are not supported on the device at all and others are not pulling all the information that they might. In the hopes that it might help improve this script, I have listed my observations below:

That is intentional; sort of an artifact of rancid's day 1 behavior.  it is
a CRS 16 router and that is the model of the cpu.  the memory should follow
those lines, such as an ASR:

!Memory: main 4194304K
!Memory: nvram 219k
!Memory: pcmcia disk0 1605616k
!Memory: pcmcia disk1 1605616k

perhaps this isn't happening for the CRS?  I dont have access to any; the ASR
is bad enough :)

I think this was blindly assumed from IOS-rancid.  Does the ASR 1k have this
command?  the 9k doesnt support it.

Looks like RSP LED info (perhaps) and PS capacity are the only interesting
bits on the ASR.  on the CRS?

nor on the 9k.  on the 1k?  Perhaps show diag summary is interesting; but it
seems mostly a duplicate of show inventory.

also likely a remnant of IOS.  on the 1k?

again, probably a remnant of IOS switches.  the 9k doesnt have show vlan.
do those show anything interesting that isnt in the config?

> 7) We should also have the command "admin show running-config" added. The reason for this is that on multi-chassis systems each chassis has it S/N entered and is assigned a rack number. In addition, fabric chassis information is recorded here.
