Buffer credit recovery support
This Fabric OS feature is supported on 8 Gbps and 16 Gbps platforms in the following configurations:
•
Between AG switch F_Port and Brocade HBA port using Adapter v3.2 or greater firmware or any
device supporting credit recovery, This feature only works at the maximum supported speed of
the HBA port (8 Gbps or 16 Gbps).
•
Between AG switch N_Port and Brocade fabric switch or cascaded AG switch F_Port.
It is highly recommended that you disable this feature on the AG switch before connecting to a switch
running Fabric OS earlier than 7.1. Enable and disable credit recovery using the
portcfgcreditrecovery command. Refer to the Fabric OS Command Reference for more information
on this command.
Specific switch platforms support this feature either in R_RDY or VC_RDY mode. In VC_RDY mode,
the buffer credit recovery is supported with fabric assigned PWWN (FA-PWWN), FEC, QoS, and
trunking Fabric OS features. In R_RDY mode, this feature is supported without FA-PWWN and QoS
Fabric OS features.
Forward error correction support
Forward error correction (FEC) is a Fabric OS feature supported in the following configurations:
•
Between the AG switch F_Port and a Brocade 16 Gbps HBA port running version 3.2 or greater
firmware.
•
Between the AG switch N_Port and F_Port on Brocade 16 Gbps fabric switch or cascaded AG
switch.
Following are limitations and considerations for FEC:
•
Supported on Brocade 16 Gbps platforms only.
•
Supported by Fabric OS 7.1.0 and later.
•
Enabled by default.
•
A Fabric OS downgrade requires FEC to be disabled.
•
Specific switch platforms support this feature either in R_RDY or VC_RDY mode.
