Asunto: Port channel keep going down

Hello,

Going through IEWB Configuring L2 etherchannel with PagP for dynamic
negotiation.
SW1 should initiate negotiation and SW2 should respond.

The port-channel comes up and stay up for a minute or two, then go down.
The ports on SW1 will go into err-disable mode.

Please help.
