Verifying Trunking Configuration
Verifying Trunking Configuration
To display trunking configuration information, perform one of the following tasks:
For detailed information about the fields in the output from these commands, refer to the Cisco MDS
NX-OS Command Reference.
The show interface command is invoked from the EXEC mode and displays trunking configurations for
a TE port. Without any arguments, this command displays the information for all of the configured
interfaces in the switch. See Examples
5-1 to 5-3.
Example 5-1 Displays a Trunked Fibre Channel Interface
switch# show interface fc1/13
fc1/13 is trunking
Hardware is Fibre Channel
Port WWN is 20:0d:00:05:30:00:58:1e
Peer port WWN is 20:0d:00:05:30:00:59:1e
Admin port mode is auto, trunk mode is on
Port mode is TE
Port vsan is 1
Speed is 2 Gbps
Receive B2B Credit is 255
Beacon is turned off
Trunk vsans (admin allowed and active) (1)
Trunk vsans (up) (1)
Trunk vsans (isolated) ()
Trunk vsans (initializing) ()
5 minutes input rate 0 bits/sec, 0 bytes/sec, 0 frames/sec
5 minutes output rate 0 bits/sec, 0 bytes/sec, 0 frames/sec
233996 frames input, 14154208 bytes, 0 discards
0 CRC, 0 unknown class
0 too long, 0 too short
236 frames output, 13818044 bytes, 0 discards
11 input OLS, 12 LRR, 10 NOS, 28 loop inits
Step 3
switch(config-if)# switchport trunk allowed vsan 2-4
Changes the allowed list for the
specified VSANs.
switch(config-if)# switchport trunk allowed vsan add 5
updated trunking membership
Expands the specified VSAN (5) to
the new allowed list.
switch(config-if)# no switchport trunk allowed vsan 2-4
Deletes VSANs 2, 3, and 4.
switch(config-if)# no switchport trunk allowed vsan add 5
Deletes the expanded allowed list.
Command Purpose
Command Purpose
show interface fc slot/port Displays the interface configuration information
that includes trunking, trunk mode, allowed
VSANs, and status.
show trunk protocol Displays whether the trunk protocol is enabled.
show interface trunk vsan numbers Displays whether the interface is trunking, and the
allowed VSAN list for each trunking interface.
