fmConfig

This command has been reclassified as an Advanced Performance Monitor (APM) command. It is no

longer displayed with the fwHelp command; it is now displayed under perfHelp.

Permissions for the operator role have changed.

Users with the operator role do not have permission to execute following commands:

• fmConfig --create

• fmconfig --change

• fmconfig --addmonitor

• fmconfig --delmonitor

• fmconfig --delete

• fmconfig --save

• fmconfig --clear

Users with the operator role are allowed to execute following commands:

• fmconfig --show

• fmconfig --help

serDesTuneMode

This command has been enhanced with new operands to support an automated tuning process to fix

CRC errors. The man page has been updated as follows; only the additions are shown below.

NAME Configures and displays SerDes tuning parameters.

SYNOPSIS serdestunemode --autoenable

serdestunemode --autodisable

serdestunemode --autoreset

serdestunemode --autoshow

DESCRIPTION Use this command to configure and display SerDes values on the Brocade FC8-16 and to control tuning

optimization of backend links for all Brocade FC8-xx blades.

When used with the --autoset, --autodisable, --autoreset and --autoshow options, this command

configures tuning optimization for backend SerDes errors. SerDes tuning optimization is indicated when

you receive RASLog errors of type C2-5825 indicating a CRC error with a good EOF. Brocade highly

recommends that you contact your service provider if you encounter such errors. If the error appears to

be an isolated incident, you may enable auto SerDes tuning for a short period of time (24-48 hours) to

see if this resolves the problem. Then disable the function to reduce the risk of resetting register values

unnecessarily if single occurrence errors are encountered. If the errors persist contact your service

provider.

OPERANDS --autoset Enables SerDes tuning optimization on all backend ports.

--autodisable Disables further tuning optimization but retains all current tuning values identified

by the algorithm.

--autoreset Disables further tuning optimization and resets all tuning values back to their

default values. If SerDes tune mode or was set, the co figuration is restored.

--autoshow Displays whether SerDes tuning optimization is enabled or disabled.
