HP Switch(config) # int a3-a5 rate-limit icmp 1

HP Switch(eth-A3-A5) # rate-limit icmp 1

Viewing the current ICMP rate-limit configuration

The show rate-limit icmp command displays the per-interface ICMP rate-limit configuration

in the running-config file.

Syntax

show rate-limit icmp <port-list>

Without [port-list], this command lists the ICMP rate-limit configuration for all ports on the

switch.

With [port-list], this command lists the rate-limit configuration for the specified interfaces. This

command operates the same way in any CLI context

Example

If you want to view the rate-limiting configuration on the first six ports in the module in slot "B":

Figure 74 Listing the rate-limit configuration

The show running command displays the currently applied setting for any interfaces in the switch

configured for all traffic rate-limiting and ICMP rate-limiting.

The show config command displays this information for the configuration currently stored in the

startup-config file. Note that configuration changes performed with the CLI, but not followed

by a write mem command, do not appear in the startup-config file.

Resetting the ICMP trap function of the port

The port ICMP trap function can be reset through SNMP from a network management station or

through the CLI with the setmib command.

Syntax

setmib hpIcmpRatelimitPortAlarmflag.internal-port-# -i 1

On a port configured with ICMP rate-limiting, this command resets the ICMP trap function, which

allows the switch to generate a new SNMP trap and an Event Log message if ICMP traffic in excess

of the configured limit is detected on the port.

Example

An operator noticing an ICMP rate-limiting trap or Event Log message originating with port A1 on

a switch would use the following setmib command to reset the port to send a new message if

the condition occurs again:

(HP_Switch_name#) setmib hpicmpratelimitportalarmflag.1 -i 1
