Port Traffic Controls
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-limit command, 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

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.
