Port Traffic Controls
Rate-Limiting
To match the port’s external slot/number to the internal port number, use the
walkmib ifDescr command, as shown in the following figure:
ProCurve# walkmib ifDescr
ifDescr.1 = A1
ifDescr.2 = A2
ifDescr.3 = A3
.
.
.
ifDescr.23 = A23
ifDescr.24 = A24
ifDescr.27 = B1
ifDescr.28 = B2
ifDescr.29 = B3
.
.
.
ifDescr.48 = B22
ifDescr.49 = B23
ifDescr.50 = B24
.
.
.

Configuring Inbound Rate-Limiting for Broadcast
and Multicast Traffic
Rate-limiting (throttling) of inbound broadcast and multicast traffic on the
switch can be configured, which helps prevent the switch from being dis-
rupted by traffic storms if they occur on the rate-limited port. The rate-limiting
is implemented as a percentage of the total available bandwidth on the port.
The rate-limit command can be executed 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
