Example:
CB9000@slot 5.1 [36L-E/FEN-TX-L2] (bridge): multicast
Menu options (CoreBuilder 9000-10AD6C):
igmp - Administer IGMP snooping
multicastLimit - Set the multicast packet rate limit
broadcastLimit - Set the broadcast packet rate limit
floodLimit - Set the flood packet rate limit
CB9000@slot 5.1 [36L-E/FEN-TX-L2] (bridge/multicast):
multicastlimit
Enter new value (0-16777216) [50000]: 100000
This example limits the total multicast traffic leaving participating
front-panel ports to 100,000 fps.
3
Activate (or deactivate) multicast limiting.
■
To activate multicast rate limiting (to turn limiting on), enter
McastBcast
■
To deactivate multicast rate limiting (to turn limiting off), enter
BcastOnly
4
From the
bridge port
menu, enter the particular packet type, to
configure each port to participate in either broadcast or flood module
rate limiting (in addition to multicast rate limiting, which you configured
in Step 3).
■
To activate broadcast or flood-rate limiting (to turn limiting on),
enter
enabled
■
To deactivate broadcast or flood-rate limiting (to turn limiting off),
enter
disabled
Example (broadcast rate limiting):
CB9000@slot 5.1 [36L-E/FEN-TX-L2] (bridge/port):
broadcastLimitMode
Select bridge ports (1-36|all|?) [1]: 1
Enter new value (disabled,enabled) [disabled]:
If you select
disabled
for a port, the port does not participate in the
module broadcast rate limiting.
The following example illustrates what happens when, for example, you
specify an egress threshold of 3,000 fps for the module’s multicast rate
limit. Ports 3 and 10 are configured to participate in module multicast
rate limiting.
