Description The config traffic control command configures broadcast,
multicast and unknown unicast storm control.
Parameters <portlist> - A port or range of ports to be configured.
all − Specifies all ports on the Switch are to be configured.
storm_type – The type of broadcast storm for which to configure the
traffic control. The options are:
broadcast – Enables broadcast storm control only.
multicast_broadcast – Enables broadcast and multicast
storm control.
dlf_ multicast_broadcast - Enables broadcast, multicast and
unknown unicast storm control.
<int 3500-1000000> − The upper threshold at which the specified
traffic control is switched on. The value is the number of
broadcast/multicast/dlf packets, in Kbps, received by the Switch that
will trigger the storm traffic control measures. The value ranges in
size from 3500 to 1000000 Kbps.
Action:
Drop – If threshold is reached, drop packet.
Shutdown – If packets are dropped for the time interval specified,
the port is shut down..
time_interval <int 5-30> - time interval after packets are dropped
until the port is shut down.
