FC-NO-CREDITS

Default Severity: Major (MJ), Service-Affecting (SA)
Logical Objects: Client port
The Fibre Channel Distance Extension Credit Starvation alarm occurs on storage access networking (SAN)
Fibre Channel/Fiber Connectivity (FICON) cards when the congestion prevents the GFP transmitter from
sending frames to the card port. For example, the alarm can be raised when an operator configures a card to
autodetect framing credits but the card is not connected to an interoperable FC-SW-standards-based Fibre
Channel/FICON port.
FC-NO-CREDITS is raised only if transmission is completely prevented. (If traffic is slowed but still passing,
this alarm is not raised.)
