I was asked to set up a port channel from my 4900M to a couple of NETAPP servers, can this be done. There are two gig ports on each servers. Port channels between switches is easy but can it be done to end items. I tried but I counldn't get my Port-Channels to come up? Maybe it's my configs? If it's just a question of failover, I have the two 4900M stacked and perfer to use HSRP.

If the server doesn't need access to more than a single vlan then no you would not need to trunk anything , just put the ports into the vlan you the server in for the port channel.

Yes it can be done if the server nics support it , you would set it up for either
an LACP etherchannel or a port channel that is forced on for both the switch and the nic depending on what the server will support , do it all the time.

I was told the servers were set up for LACP, but i keep getting a "LACP currently not enabled on the remote port" message. I assumed it was on the server end but there was no server techs available. Was i on the right path for my configs?
Port-channel 10
switchport mode trunk
switchport trunk allowed vlan 200
interface gigabit 1/2
switchport mode trunk
switchport trunk allowed vlan 200
channel-protocol lacp
channel-group 10 mode active
interface gigabit 1/3
switchport mode trunk
switchport trunk allowed vlan 200
channel-protocol lacp
channel-group 10 mode active

Yes that looks correct if the server is "supposedly" setup for lacp . Thats what we use . You are also trunking it too I see so verify things like the native vlan matches on both the switch and nics .

Thanks. I didn't consider a vlan setting on the NICs. Do i need to trunk? Am i making this harder than it needs to be? Should I just make my gig ports access ports? My goal is just to keep things at layer 2 for these customers. Already have HSRP, layer 3 and OSPF point-to-point routing running on the switch for other customers.
