Task Flow for Migrating Interfaces from Shared Mode to Dedicated Mode

To configure the Fibre Channel switching modules when starting with the default configuration or when
migrating from shared rate mode to dedicated rate mode, perform these steps:
Step 1 Take unused interfaces out of service to release resources for other interfaces, if necessary.
See the Taking Interfaces out of Service, on page
Step 2
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 Dynamic Bandwidth Management, on page
Step 3 Configure the rate mode (dedicated or shared).
See the Configuring FEC, on page
Step 4
Configure the port mode.
See the Configuring an Interface Mode , on page
Note ISL ports cannot operate in shared rate mode.
Step 5 Configure the BB_credits and extended BB_credits, as necessary.
