Chapter 5 Configuring Trunking

Configuration Example for F Port Trunking

34 output OLS, 19 LRR, 17 NOS, 12 loop inits

Example 5-2 Displays the Trunking Protocol

switch# show trunk protocol

Trunk protocol is enabled

Example 5-3 Displays Per VSAN Information on Trunk Ports

switch# show interface trunk vsan 1-1000 fc3/1 is not trunking

...

fc3/7 is trunking

Vsan 1000 is down (Isolation due to vsan not configured on peer)

...

fc3/10 is trunking

Vsan 1 is up, FCID is 0x760001 Vsan 2 is up, FCID is 0x6f0001

fc3/11 is trunking

Belongs to port-channel 6 Vsan 1 is up, FCID is 0xef0000 Vsan 2 is up, FCID is 0xef0000

...

port-channel 6 is trunking

Vsan 1 is up, FCID is 0xef0000 Vsan 2 is up, FCID is 0xef0000

Configuration Example for F Port Trunking

This example shows how to configure trunking and bring up the TF-TNP link between an F port in the NPIV core switch and an NP port in the NPV switch:

Step 1 Enable the F port trunking and channeling protocol on the MDS core switch:

switch(config)# feature fport-channel-trunk

Step 2 Enable NPIV on the MDS core switch:

switch(config)# feature npiv

Step 3 Configure the port mode to auto, F, or Fx on the MDS core switch:

switch(config)# interface fc1/2 switch(config-if)# switchport mode F

Step 4 Configure the trunk mode to ON on the MDS core switch:

switch(config-if)#switchport trunk mode on

Step 5 Configure the port mode to NP on the NPV switch:

switch(config)# interface fc1/2 switch(config-if)# switchport mode NP

Step 6 Configure the trunk mode to ON on the NPV switch:

switch(config-if)#switchport trunk mode on
