[c-nsp] problems with etherchannel between router (3725) and switch(3550)

[Danny Vernals]

sorry pasted the wrong interface in, it should have been:

interface FastEthernet0/25
switchport access vlan 3
switchport mode access
speed 100
duplex full
channel-group 1 mode on
end

port channel int is:

interface Port-channel1
switchport access vlan 3
switchport mode access
end
