NP based multicast, broadcast, and unknown-unicast rate limiting

BigIron RX(config)# ipv6 access-list sample
BigIron RX(config-ipv6-access-list sample)# permit ipv6 10:10::0:0/64 any
BigIron RX(config-ipv6-access-list sample)# deny ipv6 any any
The following configuration creates a rate limiting policy on port 1/1. The policy limits the rate of all
inbound IP traffic that matches the permit rules a rate of 100 Mbps with a maximum burst size of
200 Mbits. Traffic denied by sample is forwarded on the port.
BigIron RX(config)# interface ethernet 1/1
BigIron RX(config-if-e10000-1/1)# rate-limit in ipv6-named-access-group sample
100000000 200000000
Average rate is adjusted to 99515432 bits per second
Syntax: [no] rate-limit in ipv6-named-access-group <name> <requested-rate> <maximum-burst>
The in parameter applies the policy to traffic on inbound ports.
The ipv6-named-access-group <name> parameter identifies the IPv6 ACL used to permit or deny
traffic on a port. Permitted traffic is subject to rate limiting. Denied traffic is forwarded on the port.
For information on the other parameters, refer to “Configuring a port-based rate limiting policy” on
page 514.
NP based multicast, broadcast, and unknown-unicast
rate limiting
NOTE
Beginning with release 02.7.00, the multicast limit, broadcast limit, and the unknown-unicast limit
commands have been superseded with the multicast rate-limit, broadcast rate-limit, and the
unknown-unicast rate-limit commands. You must reconfigure the rate limiting when upgrading to
the 02.7.00 Multi-Service IronWare.
NP based Multicast, Broadcast, and Unknown-Unicast rate limiting is supported. This feature
allows hardware NP based Multicast, Broadcast, and Unknown-Unicast rate limiting for both CPU
based flooding and hardware based flooding.
To enable multicast rate-limiting on a specific port, enter a command such as the following.
BigIron RX (config)# multicast rate-limit 1000000 1 np 2/2
Syntax: [no] multicast rate-limit <avg-rate> <max-burst> np [<slot/port> | all]
To enable Broadcast rate-limiting on a specific port, enter a command such as the
following.
BigIron RX (config)# broadcast rate-limit 1000000 1 np 3/2
Syntax: [no] broadcast rate-limit <avg-rate> <max-burst> np [<slot/port> | all]
To enable unknown unicast rate-limiting on a specific port, enter a command such
as the following:
BigIron RX (config)# unknown-unicast rate-limit 1000000 1 np 4/2
Syntax: [no] unknown-unicast rate-limit <avg-rate> <max-burst> np [<slot/port> | all]
Use the no parameter to disable np rate limiting.
The <avg-rate> is entered in Kbits/sec. Possible values are from 1-429467295. The default value
is 4294967295.
