Switching Commands AT8404

AT8404 CLI Reference Manual Page 2 - 30

2.3.27 show vlan association subnet

This command displays the VLAN associated with a specific configured IP-Address and net mask. If no IP address

and net mask are specified, the VLAN associations of all the configured IP-subnets are displayed.

2.3.28 show vlan association mac

This command displays the VLAN associated with a specific configured MAC address. If no MAC address is

specified, the VLAN associations of all the configured MAC addresses are displayed.

2.4 Double VLAN Commands

This section describes the commands you use to configure double VLAN (DVLAN). Double VLAN tagging is a way

to pass VLAN traffic from one customer domain to another through a Metro Core in a simple and cost effective

manner. The additional tag on the traffic helps differentiate between customers in the MAN while preserving the

VLAN identification of the individual customers when they enter their own 802.1Q domain.

2.4.1 dvlan-tunnel ethertype

This command configures the ether-type for all interfaces. The ether-type may have the values of 802.1Q, vMAN,

or custom. If the ether-type has a value of custom, the optional value of the custom ether type must be set to a

value from 0 to 65535.

Ingress Filtering May be enabled or disabled. When enabled, the frame is discarded if this port is not a member

of the VLAN with which this frame is associated. In a tagged frame, the VLAN is identified by

the VLAN ID in the tag. In an untagged frame, the VLAN is the Port VLAN ID specified for the

port that received this frame. When disabled, all frames are forwarded in accordance with the

802.1Q VLAN bridge specification. The factory default is disabled.

GVRP May be enabled or disabled.

Default Priority The 802.1p priority assigned to tagged packets arriving on the port.
