Chapter 3 COMMANDS FOR DEBUGGING AND DIAGNOSIS

FOR PACKETS RECEIVED AND SENT BY CPU

3.1 clear cpu-rx-stat protocol

 Command: clear cpu-rx-stat protocol[ <protocol-type> ]

 Function: Clear the statistics of the CPU received packets of the protocol type.

 Parameter: <protocol-type> is the type of the protocol of the packet, including dot1x,

stp, snmp, arp, telnet, http, dhcp, igmp, ssh, bgp, bgp4plus, rip, ripng, ospf, ospfv3, pim,

pimv6, unknown-mcast, unknow-mcast6, mld

 Command Mode: Global Mode

 Usage Guide: This command clear the statistics of the CPU received packets of the

protocol type, it is supposed to be used with the help of the technical support.

 Example: Clear the statistics of the CPU receives ARP packets.

 Switch(config)#clear cpu-rx-stat protocol arp

3.2 cpu-rx-ratelimit channel

 This command is not supported by the switch.

3.3 cpu-rx-ratelimit enhanced

 This command is not supported by the switch.

3.4 cpu-rx-ratelimit protocol

 Command: cpu-rx-ratelimit protocol <protocol-type> <packets>

 no cpu-rx-ratelimit protocol <protocol-type>

 Function: Set the max rate of the CPU receiving packets of the protocol type, the no

command set the max rate to default.

 Parameter: <protocol-type> is the type of the protocol, including dot1x, stp, snmp, arp,

telnet, http, dhcp, igmp, ssh, bgp, bgp4plus, rip, ripng, ospf, ospfv3, pim, pimv6,

unknown-mcast, unknow-mcast6, mld; <packets> is the max rate of CPU receiving

packets of the protocol type, its range is 1-2000 pps.

 Command Mode: Global Mode

 Default: A different default rate is set for the different type of protocol.

 Usage Guide: The rate limit set by this command have an effect on CPU receiving

packets, so it is supposed to be used with the help of the technical support.

 Example: Set the rate of the ARP packets to 500pps.

 Switch(config)#cpu-rx-ratelimit protocol arp 500

3.5 cpu-rx-ratelimit queue-length

 This command is not supported by the switch.
