User Guidelines
•
An internal usage VLAN is required when an IP interface is configured on an Ethernet port or port-
channel.
•
This command enables the user to configure the internal usage VLAN of a port. If an internal usage
VLAN is not configured and the user configures an IP interface, an unused VLAN is selected by the
software.
•
If the software selected a VLAN for internal use and the user uses that VLAN as a static or dynamic
VLAN, the user should do one of the following:
–
Remove the IP interface.
–
Create the VLAN and recreate the IP interface.
–
Use this command to explicitly configure a different VLAN as the internal usage VLAN.
•
This command is not supported under the command interface range ethernet.
