Task Flow for Migrating Interfaces from Shared Mode to Dedicated Mode

The 48-Port, 24-Port, and 4/44-Port 8-Gbps Fibre Channel switching modules support the following features:

1-Gbps, 2-Gbps, 4-Gbps, and 8-Gbps speed traffic

Shared and dedicated rate mode

ISL and Fx port modes

Extended BB_credits

The 48-port and 24-port 4-Gbps Fibre Channel switching modules support the following features:

1-Gbps, 2-Gbps, and 4-Gbps speed traffic

Shared and dedicated rate mode

ISL (E or TE) and Fx (F or FL) port modes

Extended BB_credits

Note If you change the port bandwidth reservation parameters on a 48-port or 24-port 4-Gbps module, the change affects only the changed port. No other ports in the port group are affected.

To configure the 4-Gbps and 8-Gbps Fibre Channel switching modules when starting with the default configuration or when migrating from shared rate mode to dedicated rate mode, follow these steps:

Take unused interfaces out of service to release resources for other interfaces, if necessary.

See the "Taking Interfaces Out of Service" topic.

Configure the traffic speed to use (1 Gbps, 2 Gbps, 4 Gbps, 8 Gbps, or autosensing with a maximum of 2 Gbps or 4 Gbps).

See the "Configuring Port Speed" topic.

Configure the rate mode (dedicated or shared).

See the "Configuring Rate Mode" topic.

Configure the port mode.

See the "Configuring Interface Modes" topic.

Note ISL ports cannot operate in shared rate mode.

Configure the BB_credits and extended BB_credits, as necessary.

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