Etherchannel or Aggregated ports between switch and AIX server

[amaitre]

I have a problem with the configuration of an etherchannel or port aggregation between an 4507 Catalyst switch and a server running AIX 5.2 maintenance level 4. The two ports on the switch are on the same blade.

I tried configuring etherchannel with the command

config-if# channel-group XX mode on

and I tried configuring 802.3ad with the command

config-if# channel-group XX mode activ

but in both cases, as soon as I configured the second port, connection went down (I monitored with pings).

On the AIX, I tried configuring modes "round-robin" and "802.3ad" with both switch configurations, but the result was the same.

Does anyone has experience with this kind of configuration?

thanks,

Antoine

I thought channel-groups were for switch to switch connectivity?

Hi amaitre

Could you setting  the etherchannel with the AIX Server?

I configured in my switch 4510 with a AIX, but the 2 ports with channel-group keep in suspend. This is the configuration

interface Port-channel2

description ## LACP AIX ##

switchport

switchport access vlan 100

load-interval 30

interface GigabitEthernet4/20

description  ## LACP AIX ##

switchport access vlan 100

channel-protocol lacp

channel-group 2 mode active

spanning-tree portfast

!

interface GigabitEthernet4/21

description ## LACP AIX ##

switchport access vlan 100

channel-protocol lacp

channel-group 2 mode active

spanning-tree portfast

This configuration works with a server Dell with windows 2008.

The schema is 1 switch 4510 with etherchannel to AIX.

Thanks!
