3.6 cpu-rx-ratelimit total

 Command: cpu-rx-ratelimit total <packets>

 no cpu-rx-ratelimit total

 Function: Set the total rate of the CPU receiving packets, the no command sets the

total rate of the CPU receiving packets to default.

 Parameter: <packets> is the max number of CPU receiving packets per second.

 Command Mode: Global Mode

 Default: 1200pps.

 Usage Guide: The total rate set by the 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 total rate of the CPU receive packets to 1500pps.

 Switch(config)#cpu-rx-ratelimit total 1500

3.7 debug driver

 Command: debug driver {receive | send} [interface {<interface-name> | all}] [protocol

{<protocol-type> | discard | all}] [detail]

o no debug driver {receive | send}

 Function: Turn on the on-off of showing the information of the CPU receiving or

sending packets, the “no debug driver {receive | send}” command turns off the on-off.

 Parameter: receive | send show the information of receiving or sending packets;

 interface {<interface-list>| all}: interface-list is the Ethernet port number, all indicate

all the Ethernet ports.

 protocol {<protocol-type> | discard | all}: protocol-type is the type of the protocol of

the packet, including snmp, telnet, http, dhcp, igmp, hsrp, arp, bgp, rip, ospf, pim, ssh,

vrrp, ripng, ospfv3, pimv6, icmpv6, bgp4plus, unknown-mcast, unknown-mcast6, ttl0-

2cpu, isis, dot1x, gvrp, stp, lacp, cluster, mld, vrrpv3, ra, uldp, lldp, eapou all means all

of the protocol types, discard means all the discarded packets. Detail show detail

information.

 Command Mode: Admin Mode

 Usage Guide: This command is used to debug, it is supposed to be used with the help of

the technical support.

 Example: Turn on the on-off for showing the receiving packets.

 Switch#debug driver receive

3.8 show cpu-rx protocol

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

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

 Parameter: <protocol- type> is the protocol type of the packets, if do not input

parameters, show all statistic packets.

 Command Mode: Admin and configuration mode

 Default: None.
