Hello,
We have two Catalyst 4006 as core switchs in our network. Other access layer and server layer switchs (also Catalyst 4006) connect to the two core switchs; two Gigabit Ethernet links between one layer switch and one core switch form a port channel.
Now I add one Catalyst 4507 switch in the backbone, Il connects to each core switch by two GE links formed a port channel. The show spanning-tree command presente different port-channel type for the older(P2P Peer STP and the new port-channel (PO31, only P2P, not peer STP).

What does the type Peer STP means? I made the same configuration for PO31 like the other port-channel, why it is not in Peer STP type?
Thank you.
