SYNOPSIS
gfpOverhead sub-command options
DESCRIPTION
The gfpOverhead command is used to set several operation parameters.

enableSingleBitError
Correction true | false
Enables the use of single bit error correction. (default = true)
deltaSyncState
The number of cHEC matches (+1) needed to move the state machine from the hunt state to the sync state.

COMMANDS
The gfpOverhead command is invoked with the following sub-commands. If no sub-command is specified, returns a list of all sub-commands available.
gfpOverhead cget option
Returns the current value of the configuration option gfpOverhead by option. Option may have any of the values accepted by the gfpOverhead command, subject to the setting of the enableValidStats option.
gfpOverhead config option value
Modify the configuration options of the time server. If no option is specified, returns a list describing all of the available options (see STANDARD OPTIONS) for gfpOverhead.
gfpOverhead get chasID cardID portID [circuitID]
Gets the current preamble configuration of the circuit circuitID on port portID, on card cardID, on chassis chasID. Call this command before calling gfpOverhead cget option to get the value of the configuration option. If circuitID = 0, gets information for the port; if circuitID not 0, gets information for the circuit.
gfpOverhead set chasID cardID portID circuitID
Sets the preamble configuration of the circuit circuitID on port portID, on card cardID, on chassis chasID by reading the configuration option values set by the gfpOverhead config option value command. If circuitID = 0, gets information for the port; if circuitID not 0, gets information for the circuit.
gfpOverhead setDefault
Sets to IxTclHal default values for all configuration options.
