Hi tobias,
make sure that you only put the physical interfaces into portchannel, rest of the config is done on your portchannel. It get's replicated to the physical interfaces. If you change something directly on the gig he will bring down the etherchannel :/ (complain about different configuration between portchan and gig)

Hi there,
Maybe there are some Cisco specialists reading this List =)
On a WS-C3750X it tooks about 1 minute after connecting a port to change the status from LINK-3-UPDOWN "up" to LINEPROTO-5-UPDOWN "up"
Mar 27 16:25:37 192.168.1.144 788: *Mar 8 00:30:48.032: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to up Mar 27 16:26:38 192.168.1.144 790: *Mar 8 00:31:49.227: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/1, changed state to up
Mar 27 16:25:54 192.168.1.144 789: *Mar 8 00:31:05.086: %LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to up Mar 27 16:26:56 192.168.1.144 791: *Mar 8 00:32:06.583: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/0/1, changed state to up
The ports are configured like that:
interface GigabitEthernet1/0/1 switchport access vlan 27 switchport mode access spanning-tree portfast spanning-tree bpdufilter enable channel-group 1 mode active ! interface GigabitEthernet2/0/1 switchport access vlan 27 switchport mode access spanning-tree portfast spanning-tree bpdufilter enable channel-group 1 mode active ! interface Port-channel1 switchport access vlan 27 switchport mode access end
The server which is connected has nothing special configured... It should boot via DHCP/PXE (of course without Bonding) and then the installed Linux with Bonding configured. Does anyone have an idea why this takes so long?
Thanks!
Cheers, Tobias
