`copp user-def`

Syntax


copp user-def <copp-id> {ipv4 | ipv6}{any <protocol> <dest-port> | <dest-ipaddress> [<protocol> <dest-port>]}
     {limit <limit-val> | none | drop}
     [tcp | udp]}

no copp user-def <copp-id> {ipv4 | ipv6}{any <protocol> <dest-port> | <dest-ipaddress> [<protocol> <dest-port>]}
     {limit <limit-val> | none | drop}
     [tcp | udp]}

Description

Enables control plane policing for a user-defined traffic class. Matches on a particular ip address and layer 4 port for CoPP.

The no form of this command disables control plane policing.

Command context

config

Parameters

user-def <copp-id>: Specifies up to 8 user defined copp configurations.
{ipv4|ipv6}: Specifies control plane policing for IPv4 or IPv6.
any <protocol> <dest-port>: Specify the port number between 0-65535.
<dest-ipaddress>: Specifies the IP address of User Defined Control Plane Policing.
<protocol>: Specifies control plane policing for transport layer protocol (TCP, UDP), the destination port for the given TCP or UDP protocol .
limit <limit-val>: Specifies the rate limit value in packets per second.
none: Allows all traffic matching the user-defined traffic class with no limit.
drop: Blocks user-defined traffic from reaching the switch CPU.
tcp: Telnet protocol for user-defined control plane policing.
udp: Protocol for user-defined control plane policing.

Example

Enable control plane policing only for SNMP traffic reaching the switch at up to 80 packets per second on each slot:

switch(config)# copp user-def ipv4 any udp 161 limit 80

Example

Block all Telnet traffic from reaching the switch:

switch(config)# copp user-def 1 ipv4 any tcp 23 drop

switch(config)# show copp user-def config
