Objective: To configure port-channel and associate it to vlan.
Servers will use Cisco-NXOS as their gateway and uplink to Internet. Server-switch have Layer 2 (access mode) connectivity to Cisco-NXOS router. (see Fig.1)
Fig.1
1. Configure the Vlan (interface vlan will be the server’s gateway)
Cisco-NXOS#
configure
vlan 8name Server-Farm
interface Vlan8description Server Farm Vlanno shutdownip address 192.168.8.1/24
2. Configure port-channel
interface port-channel10description Port-channel to Server-Switchswitchport access vlan 8
3. Configure physical members
interface eth1/1description Connection to Server-Switch fa0/1switchport access vlan 8channel-group 10 mode activeno shutdown
interface eth1/2description Connection to Server-Switch fa2/0switchport access vlan 8channel-group 10 mode activeno shutdown
Verification and sample output:
Server1 = 192.168.8.20
Server2 = 192.16 8.8.21
ARP:
show ip arp <vlan id>
Cisco-NXOS# show ip arp vlan8
Flags: * – Adjacencies learnt on non-active FHRP router
+ – Adjacencies synced via CFSoE
# – Adjacencies Throttled for Glean
CP – Added via L2RIB, Control plane Adjacencies
PS – Added via L2RIB, Peer Sync
RO – Re-Originated Peer Sync Entry
D – Static Adjacencies attached to down interface

Check Port-channel:
show interface port-channel <port-channel id>
Cisco-NXOS# show int port-channel 10 | i Members
Members in this channel: Eth1/1, Eth1/2
Check Vlan:
show vlan
Cisco-NXOS# show vlan

Verify the traffic:
show int port-channel1show int vlan8show int eth1/1show int eth1/2
