Configuring Switch Acceleration
Enabling Switch Acceleration
To enable switch acceleration, perform this task in privileged mode:
Task
Step 1
Disable front-panel Gigabit Ethernet ports. set port disable mod_num/port_num
Step 2
Enable switch acceleration.
This example shows how to the enable switch acceleration on the switch:
Console> (enable) set port disable 1/1-2
Port(s) 1/1-2 disabled.
Console> (enable) set switchacceleration enable 1
Enabling or Disabling switch acceleration may impact performance for 1-2 seconds.
Do you want to continue (y/n) [n]? y
Switch Acceleration on module 1 enabled.
Console> (enable)
This example shows how to disable switch acceleration on the switch:
Console> (enable) set switchacceleration disable 1
Enabling or Disabling switch acceleration may impact performance for 1-2 seconds.
Do you want to continue (y/n) [n]? y
Switch Acceleration on module 1 disabled.
Console> (enable)
Displaying Switch Acceleration Information
To display switch acceleration status, perform this task in privileged mode:
Task
Display the current status of switch acceleration. show switchacceleration mod_num
This example shows how to display the current status of the switch acceleration feature:
Console> show switchacceleration 1
Module 1 has switch acceleration enabled.
Console>
Backplane Channel Module
The Backplane Channel Module extends the benefits of switch acceleration by providing multilink load
balancing between the switch engines. The Backplane Channel Module also allows you to retain the
Gigabit Ethernet uplinks on the supervisor engine.
