Increase the Egress Throughput on a TM Port

You can increase the egress throughput rate on a Traffic Management (TM) port on 10G and 100G line cards.

About this task

On a 10G card, you can increase the rate from 300 Mbps to 13 Gbps. On a 100G card, you can increase the rate from 300 Mbps to 130 Gbps. The maximum speed supported by an interface is 130% of the default interface speed.

If you configured a breakout connector on an Ethernet interface, you can also increase the egress throughput rate on a breakout port. For XGS-based platforms, supported drop precedence are 0, 1, and 2.

Note

This feature is supported only on devices based on Extreme 8820, SLX 9740, SLX 9640, and SLX 9540.

1. Enter global configuration mode.
   

   device# configure terminal

2. Enter interface configuration mode.
   

   device(config)# interface Ethernet 1/2

3. Increase the egress throughput rate on the port.
   

   device(conf-if-eth-1/2)# qos port-speed-up 300000

   In this example, the egress throughput rate on the port is increased by 300 Mbps.
4. Return to privileged EXEC mode.
   

   device(conf-if-eth-1/2)# end

5. Save the running-config file to the startup-config file.
   

   device# copy running-config startup-config

Example

The following example summarizes the commands in this procedure.

device# configure terminal
device(config)# interface ethernet 1/2
device(conf-if-eth-1/2)# qos port-speed-up 300000
device(conf-if-eth-1/2)# end
device# copy running-config startup-config
