vlan-id — VLAN ID of the internal usage VLAN.(Range: Valid VLAN)

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.
Examples
The following example reserves a VLAN as the internal usage VLAN of an interface..
Console (config)# ip internal-usage-vlan 10
5.27.19 show vlan
The show vlan privileged EXEC command displays VLAN information.
Syntax
show vlan [tag vlan-id | name vlan-name]
vlan-id — A valid VLAN ID
vlan-name — A valid VLAN name string. (Range: 1 - 32 characters)
