Port Shutdown With Broadcast Storm; Viewing Broadcast Storm - HP Aruba JL253A Management And Configuration Manual

Port shutdown with broadcast storm

A LAN broadcast storm arises when an excessively high rate of broadcast packets flood the LAN. Occurrence of
LAN broadcast storm disrupts traffic and degrades network performance. To prevent LAN traffic from being
disrupted, an enhancement of fault-finder commands adds new options, and the corresponding MIBs, that trigger
a port disablement when a broadcast storm is detected on that port.
Under this enhancement, the CLI commands given only supports broadcast traffic and not multicast and unicast
types of traffic.
The waiting period range for re-enabling ports is 0 to 604800 seconds. The default waiting period to re-enable a
port is zero which prevents the port from automatic re-enabling.
NOTE: Avoid port flapping when choosing the waiting period by considering the time to re-enable
carefully.
Use the following commands to configure the broadcast-storm on a port.
Syntax:
[no] fault-finder broadcast-storm [ethernet] <port-list> action [warn|warn-and-disable <seconds>] [percent <percent>|pps <rate>]
To remove the current configuration of broadcast-storm on a port, use:
Syntax:
no fault-finder broadcast-storm [ethernet] <port-list>
broadcast-storm
Configure broadcast storm control.
pps
Rising threshold level in number of broadcast packets per second.
percent
Rising threshold level as a percentage of bandwidth of the port. The percentage is calculated on 64 byte
packet size.
warn
Log the event only.
warn-and-disable
Log the event and disable the port.
seconds
Re-enable the port after waiting for the specified number of seconds. Default is not to re-enable.
Configuration examples:
switch(config)# fault-finder broadcast-storm [ethernet] <A1> action [warn-and-disable <65535>]< percent 10>
switch(config)# fault-finder broadcast-storm [ethernet] <A2> action [warn-and-disable <pps 100>
switch(config)# fault-finder broadcast-storm [ethernet] <A22> action [warn] <pps 100>
