Note : Make sure that the routers and switches have been erased and have no startup configurations. Refer to the Router Interface Summary T able at the end of the lab for the correct interface identifiers. Depending on the model and Cisco IOS version, the commands available and the output produced might vary from what is shown in th e labs. Other routers, switches, and Cisco IOS versions can be used. The switch used in the lab is a Cisco Catalyst 2960 with Cisco IOS Release 1 5.2(2) (lanbasek9 image). Note : The router s used with CCNP hands-on lab s are Cisco 4221 with Cisco IOS XE Release 1 6.9.4 (universalk9 image). Note : This lab is an exercise in configuring CoPP policies and does not necessarily reflect network best practices. The focus of this lab is using the Cisco IOS Modular QoS CLI (MQC) to implement CoPP. Other types of traffic directed to the control plane include routing updates, ( OSPF, EIGRP and BGP ) as well as management traffic, i ncluding Telnet, SNMP, SSH, NTP, and HTTP etc. The CoPP policy is applied to a dedicated control-plane interface which protects the CPU from unexpected extreme rates of traffic that could impact the stability of the router.ĬoPP handles all process-switched traffic, such as packets logged by an ACL or IP packets with header (TTL) opt i ons.
CoPP can granularly permit, drop, or rate-limit traffic to or from the CPU using a Modular QoS CLI (MQC) policy. Part 5 : (Challenge) Further Classify Default Traffic Background / ScenarioĬontrol Plane Policing (CoPP) is a protection feature for the router’s control plane CPU. Part 1: Build the Network and Configure Basic Device Settings
