TitleVLAN Internal Names
Question
What are the VLAN internal names?
Environment
EXOS
Answer
Low level EXOS uses different names or numbers for VLANs.
For example in the kernel a name is created when a VLAN is created that starts with the VLAN name partly and ends with a number.
Also a vlanInstance number is used that sometimes is referred to in some debug logs if you enable them.

To find this name and number a debug show command is available which can be used.
debug vlan show vlans <vlan> (Omitting the optional vlan name it will list all vlans)

 Slot-1 Stack.1 # debug vlan show vlan
