Layer 2 Features

Internet Group Membership Protocol (IGMP) Snooping examines IGMP

frame contents, when they are forwarded by the device from work stations to

an upstream Multicast router. From the frame, the device identifies work

stations configured for Multicast sessions, and which Multicast routers are

sending Multicast frames. The IGMP Querier simulates the behavior of a

Multicast router. This enables snooping of the Layer 2 Multicast domain even

if there is no Multicast router.

For more information, see "IGMP Snooping" on page 519.

Port mirroring monitors network traffic by forwarding copies of incoming and

outgoing packets from a monitored port to a monitoring port. Users specify

which target port receives copies of all traffic passing through a specified

source port.

For more information, see "Port Mirroring" on page 411.

Storm Control enables limiting the number of Multicast and Broadcast

frames accepted by and forwarded by the device.

When Layer 2 frames are forwarded, Broadcast and Multicast frames are

flooded to all ports on the relevant VLAN. This occupies bandwidth, and

loads all nodes connected on all ports.

For more information, see "Storm Control" on page 408.
