Enable Flooding Port - Extreme Networks ExtremeWare XOS Command Reference Manual

enable flooding port

enable flooding [all_cast | broadcast | multicast | unicast] port
[<port_list> | all]
Description
Enables egress flooding on one or more ports. With the BlackDiamond 8800 family of switches (formerly
known as Aspen) and the Summit X450 switch, you can further identify the type of packets to flood on
the specified ports. With the BlackDiamond 10K switch, you can only flood all packets or no packets.
Syntax Description
all_cast
broadcast
multicast
unicast
port_list
all
Default
Enabled for all packets.
Usage Guidelines
Use this command to enhance security and privacy and to improve network performance by disabling
Layer 2, or egress, flooding on some packets. This is particularly useful when you are working on an
edge device in the network. Limiting flooded egress packets to selected interfaces is also known as
upstream forwarding
NOTE
Disabling egress flooding with static MAC addresses can affect many protocols, such as IP and ARP among others.
The following guidelines apply to enabling and disabling egress flooding:
Disabling multicasting egress flooding does not affect those packets within an IGMP membership

group at all; those packets are still forwarded out. If IGMP snooping is disabled, multicast packets
are not flooded.
