3 Congure the exponential weight value for the WRED prole 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
Trac 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 trac on Layer 2 and Layer 3 physical
interfaces.
OS10 device monitors the current level of trac rate at xed intervals, compares the trac rate with congured levels, and drops excess
trac.
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.
Congure 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 congured
Command Mode POLICY-MAP QUEUE
Usage Information If you congure this command, you cannot use the priority command for the class.
Example
OS10(conf-pmap-que)# bandwidth percent 70
