Displaying Credit Loss Counters - Cisco Nexus 5000 Series Configuration Manual

Fibre Channel Slow Drain Device Detection and Congestion Avoidance- An Overview
The no-credit timeout feature is disabled by default. We recommend that you retain the default configuration
for ISLs and configure a value that does not exceed 358 ms (200 to 300 ms) for fabric F ports.
You can disable this feature by entering the no system timeout no-credit-drop mode F command.
The no-credit timeout value and stuck frame timeout value are interlinked. The no-credit timeout value
Note
must always be greater than the stuck frame timeout value.
