Just found this site, I think I will be here quite often!

I think my problem is pretty close to this one as well. thread558-1164967

So here it goes: I cannot post the config of my switch because it is on a class network and cannot move data from the class to the unclass.

Hopefully I can provide as much information as is required.

Anyway I am trying to setup 2 separate 6 port aggregations using LACP. I have the first one tied to gi2/1 - 6 on vlan 100. I have the second tied to gi2/7 - 12 on vlan 100. It is using the base load balancing (I believe it is src-dest-ip.

On the port config I have:
switchport
switchport mode active
switchport access vlan 100
spanning-tree portfast
channel-group 1 (or 2 for the second agg)
channel-protocol lacp

Something to that effect.

I have po1 and po2 configed with:
switchport
switchport mode access
switchport access vlan 100

Now on my servers they are saying the agg's are green, and on the switch they are telling me they are in use and bundled correctly. So everything looks good right? wrong.

Traffic will not pass. I cannot even ping the server from the switch itself.

I hope you cisco guru's can help out, I am a server guy, so fairly new to the game. Not that I didnt read the 800 pages on it before attempting. :)

Oh and btw, the server is configured through a web interface, so I can only enable to disable the agg. Though it did work on an old switch we decommissioned.
 
Finally got it... the eth ports were in VLAN100, which is right. problem lies in the po1 channel group was in VLAN100. When i moved it to VLAN1 everything started talking. I hadn't enabled intra vlan routing. But didnt need to either because it is a flat network.
 
And every now and then, Brian pops in to say "hey"...lol

What up?
