I recently upgraded a 6509 from cat6000sup.6-1-1b.bin to cat6000supk8.8-2-1.bin and encountered an unusual issue.
This 6509 has redundant supervisor 1A and msfc2's with the msfc2's running c6msfc2-ds-mz.121-2.E.bin.
After upgrading the supervisors i found that several vlan interfaces on the msfc on the redundant supervisor either totally failed to respond to pings are would respond to only one ping and then time out despite a sh ip int br showing all interfaces up and sh standby showing that this msfc had some interfaces that were the active router for certain vlans and were forwarding traffic for that vlan.
A ping to a vlan interface from a pc in that vlan always produced a response.
The msfc on the active supervisor performed as normal.
I have rolled back the upgrade and everything seems to performing fine now.
Unfortunately we do not have smartnet - not my decision - i cannot open a tac case directly with cisco although my supplier is working with me on this but has not come across this scenario before.
This post is more for information than anything but if anybody else has experienced this before i would be pleased to hear your solution.
I will go over this again to make sure but the configs were the same on the msfcs before the upgrade and were working ok.
I am running hsrp for redundancy, downgrading to 6.4(7) is not an option as i have new hardware to support which recommends 7.x (cannot remember exactly) but my supplier says these images are not for sale any more.
This is not the first time somebody has recommended using 6.4(7) instead of 8.x - is there something funny about these images?
No there is nothing wrong with 8.x. It sounds like you are not using the MSFC config-sync feature. So perhaps the guidelines specified in the document provided earlier were not followed. I mentioned 6.4(7) because the MSFC config-sync bug is not present in that code.
