Rate-Limiting

Syntax: rate-limit < bcast mcast > in percent <0-100> no rate-limit <bcast mcast> in

Enables rate-limiting and sets limits for the specified inbound broadcast or multicast traffic. Only the amount of traffic specified by the percent is forwarded.

Default: Disabled

For example, if you want to set a limit of 50 percent on inbound broadcast traffic for port 3, you can first enter interface context for port 3 and then execute the rate-limitcommand, as shown in Figure 13-6. Only 50 percent of the inbound broadcast traffic will be forwarded.

ProCurve(config)# int 3

ProCurve(eth-3)# rate-limit bcast in percent 50

ProCurve(eth-3)# show rate-limit bcast

Broadcast-Traffic Rate		Limit Maximum %
Port	Inbound Limit	Mode	Radius Override
----- +	-------------	---------	---------------
1	Disabled	Disabled	No-override
2	Disabled	Disabled	No-override
3	50	%	No-override
4	Disabled	Disabled	No-override
5	Disabled	Disabled	No-override

Figure 13-6. Example of Inbound Broadcast Rate-limiting of 50% on Port 3

If you rate-limit multicast traffic on the same port, the multicast limit is also in effect for that port, as shown in Figure 13-7. Only 20 percent of the multicast traffic will be forwarded.
