70 ExtremeWare XOS 10.1 Concepts Guide
Virtual LANs (VLANs)
VLAN Names
Each VLAN is given a name that can be up to 32 characters. VLAN names can use standard
alphanumeric characters. The following characters are not permitted in a VLAN name:
• Space
•
Comma
• Quotation mark
VLAN names must begin with an alphabetical letter. The names can be no longer than 32 characters and
must begin with an alphabetic character. The remainder of the name can be alphanumeric or contain
underscore (_) characters. VLAN names cannot be keywords.
VLAN names can be specified using the tab key for command completion.
VLAN names are locally significant. That is, VLAN names used on one switch are only meaningful to
that switch. If another switch is connected to it, the VLAN names have no significance to the other
switch.
NOTE
You should use VLAN names consistently across your entire network.
Default VLAN
The switch ships with one default VLAN that has the following properties:
•
The VLAN name is default.
• It contains all the ports on a new or initialized switch.
• The default VLAN is untagged on all ports. It has an internal VLANid of 1.
Renaming a VLAN
To rename an existing VLAN, use the following command:
configure vlan <vlan_name> name <new_name>
The following rules apply to renaming VLANs:
• After you change the name of the default VLAN, it cannot be changed back to default.
• You cannot create a new VLAN named default.
• You cannot change the VLAN name MacVlanDiscover. Although the switch accepts a name change,
after it is rebooted, the original name is recreated.
