I am unable to get separate 350 bridges to do etherchannel since upgrading CatOS on 5509. Upgraded software on 5509 from 4.2 to 5.5.
5509 connected to 3512 running 12.0 IOS.
3512 config
Fa0/3 port group 1 distribution destination
Fa0/7 port group 1 distribution destination
Fa0/11 port group 1 distribution destination
5509 config
set port channel 7/17-20 1 (admin group)
set port channel 7/17-20 on
Once STP starts forwarding I get STP loop and the 5509 ports go errdisable.
Any ideas?
It was working before the upgrade.

Did you check the bug tool kit for any known bugs in 5.5 for etherchannel support??
