Configuration Guidelines for 48-Port and 24-Port 4-Gbps Fibre Channel
Switching Modules
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
Migrating from Shared Mode to Dedicated Mode
To configure 48-port and 24-port 4-Gbps Fibre Channel switching modules when starting with the
default configuration or when migrating from shared rate mode to dedicated rate mode, follow these
guidelines:
1. Take unused interfaces out of service to release resources for other interfaces, if necessary.
See the “Taking Interfaces Out of Service” section on page 22-40.
2. Configure the traffic speed to use (1 Gbps, 2 Gbps, 4 Gbps, or autosensing with a maximum of
2 Gbps or 4 Gbps).
See the “Configuring Port Speed” section on page 22-32.
3. Configure the rate mode (dedicated or shared) to use.
See the “Configuring Rate Mode” section on page 22-33.
4. Configure the port mode.
See the “About Interface Modes” section on page 20-3.
Note ISL ports cannot operate in shared rate mode.
5. Configure the BB_credits and extended BB_credits, as necessary.
See the “Extended BB_Credits” section on page 22-23.
Migrating from Dedicated Mode to Shared Mode
To configure 48-port and 24-port 4-Gbps Fibre Channel switching modules migrating from dedicated
rate mode to shared rate mode, follow these guidelines:
1. Take unused interfaces out of service to release resources for other interfaces, if necessary.
See the “Taking Interfaces Out of Service” section on page 22-40.
2. Configure the BB_credits and extended BB_credits, as necessary.
See the “BB_Credit Buffers for Switching Modules” section on page 22-13, “BB_Credit Buffers for
Fabric Switches” section on page 22-22, and the “Extended BB_Credits” section on page 22-23.
3. Configure the port mode.
