Workgroup Conﬁguration

Workgroups explained; adding and deleting workgroups from this window

The virtual workgroups feature of the ATX allows you to restrict multicast or broadcast trafﬁc from being propagated through every bridge port on your device. This optimizes bandwidth by limiting the subnet broadcast trafﬁc — such as IP ARPs, or IPX Get Nearest Server Requests and Service Advertisement Protocol packets — to only those ports that require the trafﬁc. You deﬁne a virtual workgroup by specifying a subset of device ports, the network protocols in effect at the ports (IP, IPX, or All — any other frame type), and any IP or IPX network identiﬁer for the “broadcast domain” that you want to restrict. Each port can belong to more than one workgroup (e.g., if both IP and IPX trafﬁc are broadcast over the same network segment). In all, you can create up to 100 virtual workgroups per switch.

NOTE

The ATX does not support workgroups in ﬁrmware versions earlier than 3.2.

The following provides a brief overview of how the virtual workgroups feature works:

•When a Spanning Tree Forwarding port on an ATX receives a broadcast packet, the ATX ﬁrst determines the frame type of the packet: IP, IPX or ALL (any other frame type). (Refer to the Tools Guide for more information on bridging and Spanning Tree.)

•If no workgroups are deﬁned on the ATX, the packet will be sent out all other ports on the bridge that are in a Spanning Tree forwarding state.

•If the receiving port is part of at least one deﬁned workgroup, the ATX determines whether the workgroups to which the port belongs are conﬁgured for the packet’s frame type (i.e., IP, IPX, or ALL).
