Description
This command limits the rate at which ICMP messages are sent on a IPv6 network. To protect
against TCP SYN attacks, you can configure the Brocade device to drop TCP SYN packets when
excessive numbers are encountered. You can set threshold values for TCP SYN packets that are
targeted at the router itself or passing through an interface, and drop them when the thresholds
are exceeded.
This command supports Joint Interoperability Test Command (JITC).
Usage Guidelines
The configuration is persistent across switch reload.
Once enabled, all outbound ICMP message types are rate limited.
