Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands police police Use the police policy-map class configuration command to define a policer for classified traffic. A policer defines a maximum permissible rate of transmission, a maximum burst size for transmissions, and an action to take if either maximum is exceeded. Use the no form of this command to remove an existing policer. police rate-bps burst-byte [exceed-action {drop | policed-dscp-transmit}] no police rate-bps burst-byte [exceed-action {drop | policed-dscp-transmit}] Syntax Description rate-bps burst-byte exceed-action drop exceed-action policed-dscp-transmit Specify the average traffic rate in bits per second (bps). The range is 1000000 to 1000000000. Specify the normal burst size in bytes. The range is 8000 to 1000000. (Optional) When the specified rate is exceeded, specify that the switch drop the packet. (Optional) When the specified rate is exceeded, specify that the switch changes the Differentiated Services Code Point (DSCP) of the packet to that specified in the policed-DSCP map and then sends the packet. Defaults No policers are defined. Command Modes Policy-map class configuration Command History Release 12.2(25)SEF Modification This command was introduced. Usage Guidelines When configuring hierarchical policy maps, you can only use the police policy-map command in a secondary interface-level policy map. The port ASIC device, which controls more than one physical port, supports 512 policers (512 user-configurable policers plus 1 policer reserved for internal use). The maximum number of user-configurable policers supported per port is 63. Policers are allocated on demand by the software and are constrained by the hardware and ASIC boundaries. You cannot reserve policers per port. There is no guarantee that a port will be assigned to any policer. To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode, use the end command. OL-8916-01 Cisco Catalyst Blade Switch 3020 for HP Command Reference 2-233
