Configuring VSAN Trunking
Guidelines and Limitations
When configuring VSAN trunking, note the following guidelines:
•
We recommend that both ends of a VSAN trunking ISL belong to the same port VSAN. On platforms
or fabric switches where the port VSANs are different, one end returns an error, and the other is not
connected.
•
To avoid inconsistent configurations, disable all E ports with a shutdown command before enabling or
disabling the VSAN trunking protocol.
Enabling or Disabling the VSAN Trunking Protocol
You can enable or disable the VSAN trunking protocol.
Procedure
PurposeCommand or Action
Enters global configuration mode.configure terminal
Example:
switch# configure terminal
switch(config)#
Step 1
Disables the trunking protocol.no trunk protocol enable
Example:
switch(config)# no trunk protocol enable
Step 2
Enables trunking protocol (default).trunk protocol enable
Example:
switch(config)# trunk protocol enable
Step 3
Trunk Mode
By default, trunk mode is enabled in all Fibre Channel interfaces. However, trunk mode configuration takes
effect only in E-port mode. You can configure trunk mode as on (enabled), off (disabled), or auto (automatic).
The default trunk mode is on. The trunk mode configurations at the two ends of the link determine the trunking
state of the link and the port modes at both ends (see the following table).
