How traffic flows when more than one uplink port channel per FI came into picture

Hello Experts,

I need your help in clarifying one doubt related to ethernet uplink port channel.

as a standard design, I have 2 ethernet uplink port channels, one on each FI with 2 ports in there.
All the vlans trunk on the northbound switch with LACP configured. all traffic will use these Port channels.As there is only uplink port channel so no issues for servers to choose them. No issues till here.


In another case, i have 6 ethernet uplink port channels, 3 on each FI with 2 ports in there and diff vlan assign to them. same configured on northbound switch N7K with vdc enabled.
Po 10 with vlan 101 and 102
PO 11 with vlan 111 and 112
PO 12 with vlan 211 and 212

i didn't see any server profile and vnic mapping with uplink port channels. then how my server will came to know which uplink have to use for communicating.

it might sound you a silly question but i am bad at networks. please help.


Cheers
Andy!!

Hi Andy

On your service profile, you define vnic's and specify the vlans which are assigned to it ! And there is a MAC table per vlan.
