I have a 3750x stack running 15.0(2)SE6.
Today I started seeing some weird problems in the logs
" %ADJ-3-RESOLVE_REQ : Adj resolve request: Failed to resolve <IP Address> <vlan ID>..
To my knowledge no changes have been made except updating the NTP and Timezone settings of the switch.
The problems is that before I rebooted a vmWare - Host all communication with said host worked like a champ. After reboot of said host, the only communications that work are from the host outward. Anyone have any ideas? I would love to reboot, but as this is production hours that is not an option.
I'm also using the 3750x in a stack config wtih 15.0(2)SE6. My switches didn't seem to respond to the command "no ip cef"
Instead, I removed this log message by entering the command: "no ip route-cache cef"
Following instructions at this link: http://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/ios-software-releases-120-mainline/47205-cef-whichpath.html
This is a known bug on this IOS:
We were able to recognize software problem with 15.0(2)SE6 software. The bug is already raised with our developers and bug ID is CSCuo89272 "%ADJ-3-RESOLVE_REQ displayed continuously after upgrade to 15.0(2)SE6". The fix is not yet available, however there is workaround which can be applied.
execute "no ip cef optimize neighbor resolution"
