bottleneckMon
The credit recovery configuration command has been enhanced with a new option to perform a link
reset.
SYNTAX bottleneckmon --linkreset slot/port
DESCRIPTION The description of the Credit recovery on backend ports section has been modified to remove
references to "partial credit loss".
Use the --cfgcredittools commands to enable or disable credit recovery of external backend ports and
to display the configuration. When this feature is enabled, credit is recovered on external backend ports
(ports connected to the core blade or core blade backend ports) when credit loss has been detected on
these ports. If complete loss of credit on a Condor2 backend port causes frame timeouts, a link reset will
be performed on that port regardless of the configured setting, even if that setting is -recover off.
[...]
If you suspect complete credit loss on a particular virtual channel (VC) on a particular backend port, use
the -check option to examine that particular backend port and VC for credit loss. If the command detects
complete credit loss, it reports the information. If, in addition, you have enabled link resets on backend
ports, this command will perform a link reset on the link in an attempt to recover from the problem.
