Default Configuration
The Prohibit Internal usage VLAN list is empty.
Command Mode
Global Configuration mode
User Guidelines
The switch requires an internal VLAN in the following cases:
•
One VLAN for each IP interface is defined directly on an Ethernet port or on
a Port channel.
•
One VLAN for each IPv6 tunnel.
•
One VLAN for 802.1x.
When a switch needs an internal VLAN it takes a free VLAN with the highest VLAN
ID.
Use the vlan prohibit-internal-usage command to define a list of VLANs that cannot
be used as internal VLANs after reload.
If a VLAN was chosen by the software for internal usage, but you want to use that
VLAN for a static or dynamic VLAN, do one of the following
•
Add the VLAN to the Prohibited User Reserved VLAN list.
•
Copy the Running Configuration file to the Startup Configuration file
•
Reload the switch
•
Create the VLAN
