Catalyst QoS Lab Tips

  • Enable QoS on a  switch with mls qos at global config.
  • mls qos vlan-based under physical interfaces will….

EEM Lab Tips

  • Check that no other EEM process is running before configuring using show event manager policy registered.
  • Create a process with event manager applet MY_PROCESS.
  • Applets are just IF and THEN statements. IF is a match and THEN is an action.
  • The IF Statement: event cli pattern “.*interface loopback.*” sync yes – Here we are looking for somebody typing on the CLI ‘interface loopback’. The [dot/period] means wildcard or anything and the [asterix] means zero or more occurrence of the [dot/period].
  • The THEN Statement: Perform the following commands to shutdown the interface
    • action 1.0 cli command “enable”
    • action 1.1 cli command “configure terminal”
    • action 1.2 cli command “$_cli_msg” (variable to get to the same interface)
    • action 1.3 cli command “shutdown”
  • Verify with debug event manager all

WCCP Lab Tips

  • Typically two lines of CLI. One to redirect and one to listen to WCCP members join requests etc.
  • redirect-list is the access-list corresponding to the subnets you wish to redirect.
  • group-list is the access-list corresponding to the WCCP member(s).
  • Configure at the global command and then configure at the interface to specify A) The Redirect [ip wccp 99 redirect in] and B) The listener [ip wccp group-listen].
  • show ip wccp to verify.

Local Authorisation Lab Tips

  • Must grant ‘confiiguration‘ access for relevant components to show up in the running-configuration.
  • As long as they do not have access to conf t then allowing configuration access to other components will not matter and therefore will show up in the show run without letting them access it.
  • Verify with show privilege.

(config)#enable secret level 2 CICSO ——-> (prompts for password CISCO)

(config)#privilege exec level 2 show run ——-> (allows level 2 to issue show run)

(config)#privilege configure level 2 hostname

  • (allows level 2 to configure hostname, however as there no conf t access, this will only show up in show run

EIGRP Lab Tips

  • Big Large Dogs eat Red Meat – Easy way to remember to EIGRP metrics; Bandwidth, Load, Delay, Reliability and MTU

Other People’s success and failures


  • – This guy passed his first attempt in 363 days and split his revision between core tasks and IP Services, using INE mock tests to mark his progress. He finished the exam with 2 hours to spare.

Core and Non-Core Lab Tasks

Original source of information can be found here:


Typical Core Tasks:

  • Basic VLAN configuration – without this working many of the later tasks will fail.
  • Basic trunk configuration – unless VLANs are transported between switches many later tasks will fail.
  • Basic serial/frame-relay configuration – many later tasks depend on this connectivity.
  • Basic IGP routing – BGP, MPLS, Multicast depend on this.
  • Authentication required to communicate with Back-Bone Router – if authentication is not correctly configured, you will not establish layer-2 and/or routing.
  • BGP/MPLS configuration where other tasks use the MPLS core for connectivity


Typical Non-Core Tasks:

  • Specific STP configuration – as long as basic trunking is working, later tasks can be configured – only points for the STP configuration will be lost.
  • Authentication between YOUR routers/switches – as long as you have connectivity later tasks can work – you would just lose the authentication points.
  • IP services tasks where no other task depends on the IP services to be configured.
  • Security/ACL/QoS tasks where no other task depends on these – be careful, because mis-configured security/QoS can cause other tasks to fail.
  • Multicast tasks where no other service depends on a working multicast network – other tasks such as NTP using a multicast group address could be affected if multicast is not configured or is mis-configured.
