Example
The following example maps priority 2 and 3 to TCG 0 for port 5.
Console(config)#interface ethernet 1/5
Console(config-if)#traffic-class map 2 1
Console(config-if)#traffic-class map 3 1
Console(config-if)#
traffic-class weight Use this command to configure the bandwidth allocation for all TCGs on an
interface. Use the no form to restore the default settings.
Syntax
traffic-class weight weight1 weight2 weight3
no traffic-class weight
weight1~3 - The percentage of bandwidth assigned to each TCG.
(Range: 0-100)
Default Setting
0
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
â—† The cumulative weight for all three TCGs must be 100.
â—† The weight assigned by the traffic-class weight command must be 0 for any
TCG set to strict mode with the traffic-class algo command.
â—† The weight for up to three TCGs may be defined. The bandwidth available to
the TCGs is the maximum percentage of available link bandwidth after all of the
packets with priorities configured for strict mode have been serviced. Once
these have been processed, a TCG may only use available bandwidth up to the
maximum percentage allocated by the traffic-class weight command.
However, the unused bandwidth of any TCG may be shared by other TCGs.
Example
The following example sets the maximum bandwidth for TCGs 0-3 on port 5 to 25,
35, and 40 percent, respectively.
Console(config)#interface ethernet 1/5
Console(config-if)#traffic-class weight 25 35 40
Console(config-if)#
