Trunk-Allowed Vsan Lists - Cisco Nexus 5500 Series NX-OS Configuration Manual

Configuring VSAN Trunking
Step 5
Step 6
EXAMPLES
This example shows how to configure a vFC interface in trunk mode:
switch# configure terminal
switch#(config)# vfc 200
switch(config-if)# switchport trunk mode on
This example shows the output for the vFC interface 200 in trunk mode:
switch(config-if)# show interface vfc200
vfc200 is trunking (Not all VSANs UP on the trunk)
Bound interface is Ethernet1/3
Hardware is Virtual Fibre Channel
Port WWN is 20:c7:00:0d:ec:f2:08:ff
Peer port WWN is 00:00:00:00:00:00:00:00
Admin port mode is E, trunk mode is on
snmp link state traps are enabled
Port mode is TE
Port vsan is 1
Trunk vsans (admin allowed and active) (1-6,10,22)
Trunk vsans (up)
Trunk vsans (isolated)
Trunk vsans (initializing)
5 minute input rate 0 bits/sec, 0 bytes/sec, 0 frames/sec
5 minute output rate 0 bits/sec, 0 bytes/sec, 0 frames/sec
last clearing of "show interface" counters never
Interface last changed at Mon Jan 18 10:01:27 2010

Trunk-Allowed VSAN Lists

Each Fibre Channel interface has an associated trunk-allowed VSAN list. In TE-port mode, frames are
transmitted and received in one or more VSANs specified in this list. By default, the complete VSAN range
(1 through 4093) is included in the trunk-allowed list.
The common set of VSANs that are configured and active in the switch are included in the trunk-allowed
VSAN list for an interface, and they are called allowed-active VSANs. The trunking protocol uses the list of
allowed-active VSANs at the two ends of an ISL to determine the list of operational VSANs in which traffic
is allowed.

Configuring VSAN Trunking
Purpose
Disables the trunk mode for the specified interface.
Trunk mode cannot be turned off for
Note
virtual Fibre Channel interfaces.
Configures the trunk mode to auto mode, which
provides automatic sensing for the interface.
