It has to do with how NX-OS handles features that aren't enabled (and/or aren't available on that hardware platform).

In 3.1, I went into the nxrancid script and changed the return value for invalid commands since I have some devices that can use some of the stock commands and some cannot and I didn't want to create a slew of new device types.

diff -u nxrancid.orig nxrancid

In 3.2, that has moved to the nxos module.

I'm sure there's probably a better way to handle it, but I was feeling pretty lazy at the time and haven't had a chance to revisit it.

Hi all,

I have some Cisco MDS 9148 switches running NX-OS 5.2(2) (m9100-s3ek9-kickstart-mz.5.2.2.bin) and rancid is v3.1. Unfortunately I am not getting good retrievals from them. Below is the results of nxrancid –d. Can someone assist in understanding the problem and suggesting a solution?
