3 Congure the exponential weight value for the WRED prole in the WRED CONFIGURATION mode.
OS10(config-wred)# random-detect weight 4
4 Enable ECN.
OS10(config-wred)# random-detect ecn
5 Enable WRED/ECN on a queue.
OS10(config)# class-map type queuing c1
OS10(config-cmap-queuing)# match queue 2
OS10(config-cmap-queuing)# exit
OS10(config)# policy-map type queuing p1
OS10(config-pmap-queuing)# class c1
OS10(config-pmap-c-que)# random-detect wred_prof_1
6 Enable WRED/ECN on a port.
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# random-detect wred_prof_1
7 Enable WRED/ECN on a service-pool.
OS10(config)# system qos
OS10(config-sys-qos)# random-detect pool 0 wred_prof_1
Storm control
Trac storms created by packet ooding or other reasons may degrade the performance of the network.
The storm control feature allows you to control unknown unicast, multicast, and broadcast trac on Layer 2 and Layer 3 physical
interfaces.
OS10 device monitors the current level of trac rate at xed intervals, compares the trac rate with congured levels, and drops excess
trac.
By default, storm control is disabled on all interfaces. You can enable storm control using the storm-control { broadcast |
multicast | unknown-unicast } rate-in-pps command in the INTERFACE mode.
Congure storm control
• The following example enables broadcast storm control with a rate of 1000 packets per second (pps) on Ethernet 1/1/1.
OS10(conf-if-eth1/1/1)# storm-control broadcast 1000
QoS commands
bandwidth
Assigns a percentage of weight to the queue.
Syntax
bandwidth percent value
Parameters percent value — Enter the percentage assignment of bandwidth to the queue (1 to 100).
Default Not congured
Command Mode POLICY-MAP QUEUE
Usage Information If you congure this command, you cannot use the priority command for the class.
Example
OS10(conf-pmap-que)# bandwidth percent 70
