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

.

Figure 13-5. Matching Internal Port Numbers to External Slot/Port NumbersConfiguring 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-limitcommand 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
