Configuring Switch Acceleration

Configuring Switch Acceleration
By default, switch acceleration is disabled on the Supervisor Engine II.
Before you enable switch acceleration, you need to disable the two front-panel Gigabit Ethernet uplink
ports on Supervisor Engine II.
To enable switch acceleration, perform this task in privileged mode:
Task
Step 1
Disable front-panel Gigabit
Ethernet ports.
Step 2 Enable switch acceleration.
This example shows how to enable switch acceleration on the switch:
Console> (enable) set port disable 1/1-2
Port(s) 1/1-2 disabled.
Console> (enable)
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 current status of switch acceleration.
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. A Backplane Channel module also allows you to retain the
Gigabit Ethernet uplinks on the supervisor engine.
