Configuring Port-Channel and VLAN in Cisco Nexus

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 8
  name Server-Farm
interface Vlan8
  description Server Farm Vlan
  no shutdown
  ip address 192.168.8.1/24
 
2. Configure port-channel
 interface port-channel10
   description Port-channel to Server-Switch
   switchport access vlan 8
3. Configure physical members
 interface eth1/1
 description Connection to Server-Switch fa0/1
 switchport access vlan 8
 channel-group 10 mode active
 no shutdown
interface eth1/2
 description Connection to Server-Switch fa2/0
 switchport access vlan 8
 channel-group 10 mode active
 no shutdown
Verification and sample output:
Server1 = 192.168.8.20
Server2 = 192.16 8.8.21
ARP:
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

192.168.8.21 00:15:47  0011.abcd.ef01  Vlan8
Ping:
Cisco-NXOS# ping 192.168.8.20 source 192.168.8.1

5 packets transmitted, 5 packets received, 0.00% packet loss
round-trip min/avg/max = 0.394/0.489/0.62 ms
Check Port-channel:
Cisco-NXOS# show int port-channel 10 | i Members
  Members in this channel: Eth1/1, Eth1/2
Check Vlan:
Cisco-NXOS# show vlan
8  Server-Farm                    active    Po10
Verify the traffic:
show int port-channel1
show int vlan8
show int eth1/1
show int eth1/2
