ip_icmp_err_interval and ip_icmp_err_burst

Description

Control the rate of IP in generating IPv4 or IPv6 ICMP error messages. IP generates only up to ip_icmp_err_burst IPv4 or IPv6 ICMP error messages in any ip_icmp_err_interval. This parameter protects IP from denial of service attacks. Set ip_icmp_err_interval to 0 to disable IP to generate IPv4 or IPv6 ICMP error messages.

Default

100 milliseconds for ip_icmp_err_interval

10 for ip_icmp_err_burst

Range

1 - 99,999 for ip_icmp_err_burst

Dynamic?
