Usage Scenario
To query information about users who send a large number of DHCP/DHCPv6/ICMP/ICMPv6/LDP-HELLO/RSVP/OSPF/RIP/PIM/ISIS/VRRP packets to the CPU or trigger a Layer 2 loop, run the display cp-rate-limit port command.
The display cp-rate-limit command displays statistics about attack packets on a specific board. The display cp-rate-limit interface command displays statistics about attack packets on a specific interface. The display cp-rate-limit interface pe-vid command displays statistics about attack packets on a QinQ interface.
The actual command output varies according to the device. The command output here is only an example.
