Application Example

The following diagram illustrates a simple

802.1Q

application:

Simple 802.1Q Application

In the above diagram, the PC devices (endstations) need to be segmented into different

802.1Q VLANs

. The switch port to which each device attaches is assigned to an

802.1Q

group

(Group 2 for endstations A, B, E, and F, and Group 3 for endstations C, D, G, and H).

The ports connecting Switch X and Switch Y are also added to 802.1Q groups 2 and 3. All of

the switch ports that handle 802.1Q traffic are now capable of passing 802.1Q information.

Only Mammoth ASIC-based Ethernet and Fast Ethernet ports can be part of an

802.1Q

group.

Existing policies for a mobile group will not be affected by the group’s support for

802.1Q

By matching switch ports with

802.1Q

groups, you are statically assigning the port to the

group. Once assigned, an

802.1Q

port cannot be dynamically assigned to another group.

However, the same switch port can be statically assigned to more than one

802.1Q

group.
