configure vman ethertype

configure vman ethertype value [primary | secondary]


Changes the default ethertype for the VMAN header.

Syntax Description

value Specifies an ethertype value in the format of 0xffff.
primary Assigns the ethertype as the primary Ethernet value.
secondary Assigns the ethertype as the secondary Ethernet value.


Ethertype value of 0x88a8 and type primary.

Usage Guidelines

The software supports two VMAN ethertype values: a primary value and a secondary value. By default, the primary ethertype applies to all VMANs. To use the secondary ethertype, define the ethertype with this command, and then assign the secondary ethertype to ports with the following command:

configure port port_list ethertype {primary | secondary}

If your VMAN transits a third-party device (other than an Extreme Networks device), you must configure the ethertype for the VMAN tag as the ethertype that the third-party device uses. If you configure both primary and secondary ethertypes, you can connect to devices that use either of the two values assigned.

The system supports all VMAN ethertypes, including the standard ethertype of 0x8100.


The following command changes the VMAN ethertype value to 8100:

configure vman ethertype 0x8100


This command was first available in ExtremeXOS 11.0.

Support for a secondary ethertype was added in ExtremeXOS 12.1.
