LACP with host - Automatic or manual?

[danielashleysmith]

Hi,

I've got a HP server, which has two NIC's, which I've managed to team together to form one logical network device with a single IP address. I've done this for redundancy and increased throughput. The two physical connections are split across two switches, which are stacked.

My question was, I read in a CCENT book that switches often detect channel-groups from other switches and auto-aggregate the ports that are connected. Does the same thing occur with a host that has two or more NIC's teamed?

And if so, does this work on a stacked pair of switches, or do I need to setup some kind of multi-chassis link aggregation channel-group for the teamed host?

If anybody could let me know how they would do this I'd appreciate it.

Thanks

Hi,

For a CROSS stack channel group something like this should use LACP to talk with load balancing to your server
Let us say for example - channel group 10 and the ports are to be in vlan 10

!
interface port-channel 10
switchport mode access
switchport access vlan 10
desc *** LACP CHANNEL 10 TO SERVER TEAM ***
!
!
interface g1/0/1
channel-group 10 mode active
!
interface g2/0/1
channel-group 10 mode active
!
