Catalyst 6500 Supervisor 2 firmware

I recently had a Catalyst 6500 Supervisor 2 fail and needed a complete replacement. It was one of a redundant pair and when the replacement unit arrived it had different firmware on it. Redundant pairs should have matched firmware, so I had to update it. Just in case this ever happens again, I wanted to record this information somewhere because it’s quite a tricky process.

How to upgrade ROMMON bootrom:

upgrade rom-monitor slot 2 rp file tftp://x.x.x.x/c6msfc2-rm2.srec.122-17r.S5

Apart from the ROMMON flash regions, there are two flash filesystems on a Supervisor Engine 2 with MSFC and PFC (WS-X6K-SUP2-2GE)

  • bootflash:
  • sup-bootflash:

and if the second unit is present

  • slavebootflash:
  • slavesup-bootflash:

The route processor (rp) bootimage (e.g. c6msfc2-boot-mz.121-19.E1a.bin) should be on bootflash:

The full image (e.g. c6k222-pk9s-mz.122-17d.SXB4.bin) should be on sup-bootflash:

You can run limited commands on the standby supervisor using:

remote login module 2

You can query the ROMMON boot rom status like so:

show rom-monitor slot 1 rp

Gold means the version in ROM, F1 and F2 are the two flash regions. rp is the route processor, sp is the switch processor.

slot 1 (as route processor boots)
