> # Task Flow for Configuring 4-Port 10-Gbps Module Interfaces

> The 4-port 10-Gbps switching modules support the following features:

> - Only 10-Gbps speed traffic
> - Only dedicated rate mode
> - ISL (E or TE) and F port modes
> - Extended BB_credits
> - Performance buffers

> To configure 4-port 10-Gbps switching modules when starting with the default configuration, follow these steps:

> 1. Configure the port mode.

> See the "Configuring Interface Modes" topic.

> 2. Configure the BB_credits, performance buffers, and extended BB_credits, as necessary.

> See the "Configuring Buffer-to-Buffer Credits" topic, and the "Configuring Extended BB_credits" topic.
