CheetahSwitch Workgroup-4508

Forwarding Traffic with Unknown VLAN Tags

Up to 2048 VLANs are supported by the IEEE 802.1Q protocol, but this switch only supports 16 VLANs. Therefore, if this switch is attached to any device that forwards frames with unknown VLAN tags, or to endstations which issue VLAN registration requests for unknown VLANs, this traffic will be dropped.

Class-of-Service (CoS) Support

The CheetahSwitch Workgroup-4508 provides two transmit queues on each port, with a weighted round-robin scheme. This function can be used to provide independent priorities for various types of data such as real-time video or voice, and best-effort data.

Priority assignment to a packet in the CheetahSwitch is accomplished through explicit assignment by end stations which have applications that require a higher priority than best-effort. This switch utilizes the IEEE 802.1p and 802.1Q tag structure to decide priority assignments for the received packets.

IGMP Snooping and IP Multicast Filtering

The Internet Group Management Protocol (IGMP) runs between hosts and their immediately neighboring multicast router/switch. The protocol’s mechanisms allow a host to inform its local router/switch that it wants to receive transmissions addressed to a specific multicast group.

A router, or multicast-enabled switch, can periodically ask their hosts is they want to receive multicast traffic. If there is more than one router/switch on the LAN performing IP multicasting, one of these devices is elected “querier” and assumes the responsibility of querying the LAN for group members.

Based on the group membership information learned from IGMP, a router/switch can determine which (if any) multicast traffic needs to be forwarded to each of its ports. At Layer-3, multicast routers use this information, along with a multicast routing protocol, to support IP multicasting across the Internet.

IGMP provides the final step in an IP multicast packet delivery service since it is only concerned with forwarding multicast traffic from the local router/switch to group members on directly attached subnetwork or LAN segment.

This switch supports IP Multicast Filtering by:

•Passively snooping on the IGMP Query and IGMP Report packets transferred between IP multicast routers and IP multicast host groups to learn IP Multicast group members, and

•Actively sending IGMP Query messages to solicit IP Multicast group members (see page 2-23 or 3-25).
