Instructions
How to create a port channel on a Cisco switch.
Step 1: On switch1:
- Create the Port-Channel.
switch1# config terminal
Enter configuration commands, one per line, ending with CNTL/Z.
switch1(config)# interface fc1/1, fc2/1
switch1(config-if)# channel-group 2
fc1/1 fc2/1 added to port channel 2 and disabled.
Do the same operation on the switch at the other end of the port channel, then do "no shutdown" at both ends to bring them up.switch1(config-if)# switchport description "To switch2 PortChannel2"
- Enable trunking (TE) and set the VSAN allowed list on switch1.
switch1# config terminal
switch1(config)# int port-channel 2
switch1(config-if)# switchport trunk mode on
switch1(config-if)# switchport trunk allowed vsan 1
switch1(config-if)# switchport trunk allowed vsan add 10
Step 2: On switch2:
- Create the port channel on switch2, including setting the description.
switch2# config terminal
Enter configuration commands, one per line, ending with CNTL/Z.
switch2(config)# interface fc1/1, fc2/1
switch2(config-if)# channel-group 2
fc1/1 fc2/1 added to port channel 2 and disabled.
Do the same operation on the switch at the other end of the port channel, then do "no shutdown" at both ends to bring them up.switch2(config-if) # switchport description "To switch1 PortChannel2"
- Enable trunking (TE) and set the VSAN allowed list on switch1.
switch2# config terminal
switch2(config)# int port-channel 2
switch2(config-if)# switchport trunk mode on
switch2(config-if)# switchport trunk allowed vsan 1
switch2(config-if)# switchport trunk allowed vsan add 10
Step 3: Enable the interfaces to bring up the port channel:
- Switch1:
switch1# config terminal
Enter configuration commands, one per line, ending with CNTL/Z.
switch1(config)# interface fc1/1, fc2/1
switch1(config-if)# no shut - Switch2:
switch2# config terminal
Enter configuration commands, one per line, ending with CNTL/Z.
switch2(config)# interface fc1/1, fc2/1
switch2(config-if)# no shut
Step 4: Verify the port channel has come up:
switch1# show interface port-channel 2
port-channel 2 is trunking
Port description is To switch2 PortChannel2
Hardware is Fibre Channel
Port WWN is 24:02:00:0c:85:e9:d2:c0
Admin port mode is E, trunk mode is on
Port mode is TE
Port vsan is 1
Speed is 4 Gbps

Additional Information
Port-Channels allow for the aggregation of multiple FC or FCIP links into a single, higher speed, fault tolerant FC or FCIP ISL. It has the same configuration options as a single link FC or FCIP ISL as far as configuration is done.
