icmp (Error Message Rate Limit)

Syntax

Hierarchy Level

Description

Configure the rate at which ICMP messages are generated for IPv4 packet errors for non-ttl-expired packets. Although you configure the rate limit at the [edit chassis] hierarchy level, it is not a chassis-wide limit. Instead, the rate limit applies per interface family. This means, for example, that multiple physical interfaces configured with family inet can simultaneously generate the ICMP error messages at the configured rate.

Note:

This rate limit takes effect only for traffic that lasts 10 seconds or longer. The rate limit is not applied to traffic with a shorter duration, such as 5 seconds or 9 seconds.

Note:

This statement does not apply to ICMP messages for ttl-expired packets; for these errors, the rate is fixed at 500 pps.

Options

rate-limit rate-limit—Rate in packets per second (pps). Starting in Junos OS Release 18.4R1, the maximum rate is 1000 pps. In earlier releases, the maximum rate is 50 pps.

  • Range: 1 through 1000

  • Default: 1
