the port. This is the
default. The options
are equivalent.
mcastrate Specifies the maximum number of ingress multicast
packets a switch port accepts each second. The
range is 0 to 262,143 packets. The default is
262,143 packets.
unkucastratelimiting Enables or disables rate limit for unknown ingress
unicast packets. The options are:

Description
This command sets the maximum number of ingress packets a port
accepts each second. Packets exceeding the threshold are discarded.
You can enable the rate limiting threshold independently for broadcast,
multicast and unknown unicast packets.
Examples
The following command activates rate limiting for ingress broadcast and
multicast packets on port 6. It sets a threshold of 20,000 packets per
second for broadcast packets and 100,000 for multicast packets:
set switch port=6 bcastratelimiting=yes bcastrate=20000
mcastratelimiting=yes mcastrate=100000
The following command sets a threshold of 150,000 packets per second
for unknown ingress unicast packets on ports 15 and 17:
