Default
A VLAN named Default exists on all new or initialized Extreme switches:
• It initially contains all ports on a new or initialized switch, except for the management port(s), if

• It has an 802.1Q tag of 1.
• The default VLAN is untagged on all ports.

An untagged VLAN named MacVlanDiscover exists on all new or initialized Extreme switches:
• It initially contains no ports.
• It does not initially use an 802.1Q tag, and is assigned the next available internal VLANid starting
with 4095.
A VLAN named Mgmt exists on switches that have management modules or management ports.
• It initially contains the management port(s) the switch.
• It is assigned the next available internal VLANid as an 802.1Q tag.
Usage Guidelines
A newly-created VLAN has no member ports, is untagged, and uses protocol filter any until you
configure it otherwise. Use the various
configure vlan commands to configure the VLAN to your
needs.
Internal VLANids are assigned automatically using the next available VLANid starting from the high
end (4095) of the range.
Each VLAN name can be up to 32 standard alphanumeric characters, but must begin with an
alphabetical letter. Quotation marks can be used to enclose a VLAN name that does not begin with an
alphabetical character, or that contains a space, comma, or other special character.
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.
vlan_name Specifies a VLAN name (up to 32 characters).
