Solved: Port channel

sightlay8 · ‎09-08-2009

We have about 20 servers with dual NICs, we want to run NIC teaming with port channel enable, so we need to create 20 port-channel interfaces. I want to know will this cause a performance issue in a 6509 switch with sup-720?

Hello Tak,

you should be fine:

>> With Release 12.2(18)SXE and later releases, the group_number can be 1 through 256, up to a maximum of 128 port-channel interfaces. With releases earlier than Release 12.2(18)SXE, the group_number can be 1 through 256, up to a maximum of 64 port-channel interfaces.

Hope to help

Are you planning on connecting your servers to 2 6509s?

We have our servers with NIC teaming connected to a pair of VSS switches running LACP. This way you get NIC redundency and switch redundency

I did not know about VSS until you mentioned. I think it is too much for us to implement that now. We will get the NIC redundancy only this time. But could answer my question, I have about 20 LACP in one 6500, is this no problem, or too many, I just what to get an idea?

thanks

Cisco IOS Release 12.2SX supports a maximum of 128 EtherChannels.
