Command Mode
Interface configuration (Ethernet, port-channel)
User Guidelines
• An internal usage VLAN is required when an IP interface is defined on Ethernet port or Port-
channel.
• Using this command the user can define the internal usage VLAN of a port.
• If an internal-usage is not defined for a Port, and the user wants to define an IP interface, the
software chooses one of the unused VLANs.
• If a VLAN ID was chosen by the software for internal usage, and the user wants to use that
VLAN ID for static or dynamic VLAN, he should either remove the IP interface, creates the
VLAN, and recreate the IP interface, or use this command to define explicit internal usage
VLAN.
