Supported Limiting Broadcast, Multicast, and Unknown Unicast
Traffic Features
Lists supported Limiting Broadcast, Multicast, and Unknown Unicast Traffic features supported on
FastIron devices.
The following table lists the individual BrocadeFastIron switches and the rate limiting and rate shaping
features they support. These features are supported in the Layer 2 and Layer 3 software images,
except where explicitly noted.

Configuration notes and feature limitations
Brocade devices can forward all flooded traffic at wire speed within a VLAN. However, some third-party
networking devices cannot handle high rates of broadcast, multicast, or unknown-unicast traffic. If high
rates of traffic are being received by the Brocade device on a given port of that VLAN, you can limit the
number of broadcast, multicast, or unknown-unicast packets or bytes received each second on that
port. This can help to control the number of such packets or bytes that are flooded on the VLAN to other
devices.
The following describes feature differences on FastIron devices:
• FastIron X Series devices with generation 3 line cards
‐ The control traffic is affected when broadcast, multicast and unknown unicast rate limit is
applied on an interface on FastIron X Series devices with generation 3 line cards (SX-
FI8XG, SX-FI-2XG, SX-FI-24HF, SX-FI- 24GPP, SX-FI-48GPP).
• FastIron X Series devices, except for the SX-FI48GPP interface module for all generation 2
line cards
