Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
Configuring the Secondary-Level (Child) Policy Map
Follow these steps to create a child policy map for traffic shaping.
Step 1 Use the policy-map command to specify the policy map for which you want to configure shaping and
enter policy-map configuration mode.
Router(config)# policy-map output-policy
Step 2 Use the class command to specify the traffic class to which the policy map applies.
Router(config-pmap)# class class1
Router(config-pmap-c)#
Step 3 Use the bandwidth command to specify the bandwidth allocated to the policy map. You can specify the
bandwidth in kbps, a relative percentage of bandwidth, or an absolute amount of bandwidth.
Router(config-pmap-c)# bandwidth percent 50
Step 4 Exit configuration mode.
Router(config-pmap-c)# end
Router#
For more information about configuring shaping, see Regulating Packet Flow on a Per-Class
Basis---Using Class-Based Traffic Shaping.
Note The Cisco MWR 2941 does not support all of the commands described in the IOS Release 12.2SR
documentation.
Configuring Ethernet Trusted Mode
The Cisco MWR 2941 supports trusted and non-trusted mode for switch ports. Switch ports are set in
non-trusted mode by default; if you want to set the ethernet switch ports in trusted mode, use the global
command switch l2trust to set all ethernet ports to trusted mode.
Router(config)# switch l2trust
For more information about the switch l2trust command, see the Appendix B, “Cisco MWR 2941
Router Command Reference.”
Configuring Link Noise Monitor
Noise on T1 and E1 links that span between the BTS and central office can affect voice quality for
mobile users to the point where it becomes unacceptable. To monitor the quality of individual links in a
multilink bundle, you can configure the Link Noise Monitor (LNM) on your Cisco MWR 2941 router.
The LNM detects, alerts, and removes noisy links from a bundle based on user-defined thresholds and
durations. In addition, the LNM notifies the operator once the quality of the line has improved, and
restores the link service if the link has been removed.
