Release K.13.04 Enhancements
Operating Notes
• If the configured BOOTP gateway address becomes invalid, DHCP relay agent returns
to the default behavior (assigning the lowest-numbered IP address).
• If you try to configure an IP address that is not assigned to that interface, the configu-
ration will fail and the previously configured address (if there is one) or the default
address is used.
■ Enhancement (PR_ 0000000086) — This enhancement allows rate-limiting of inbound
broadcast and multicast traffic on the switch.
Inbound Rate-Limiting for Broadcast and Multicast Traffic
This enhancement allows rate-limiting (throttling) of inbound broadcast and multicast traffic on the
switch. The rate-limiting is implemented as a percentage of the total available bandwidth on the port.
Rate-limiting inbound broadcast or multicast traffic helps prevent the switch from being disrupted
by traffic storms if they occur on the rate-limited port.
You can execute the rate-limit command from the global or interface context, for example:
ProCurve(config)# interface 3 rate-limit bcast in percent 10
or
ProCurve(config)# interface 3
ProCurve(eth-3)# rate-limit bcast in percent 10
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 1. Only 50 percent of the inbound broadcast traffic will be forwarded.
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
