it is very helpful, Mark.  i will check them out after i make sure the physical is up.    i think i might figure out why the ports showed dead. Now I remeber we did have spanning-tree bpdugard enable in global. I think the peer ports could be err-disabled as soon as I connected them. Even though i disable bpdugard, but the interfaces were  disabled, i think...    thanks,     ... View more

During my change on Saturday, i tried to use g5/5 (WS-X4548-GB-RJ45V)  on both switches, but could not bring them up, i tried to change cables and another port g7/20, nothing worked. Both ports were shown down and down.  So  I changed to T4/1 which was one of the sup ports, than it worked. The currect state is good with port T4/1s as trunk ports on both side.  HSRP configuration is not issue.    I was wandering why the HSRP peers could not be brought up using non sup ports.     Do you have a live network with HSRP configured using non-sup ports?   thanks, ...
