<minpdelayreqintv>: [-7..5] Log2 of min delay req interval in sec.
<delayasymmetry>: path delay asymmetry measured in ns
<ingresslatency>: ingress latency measured in ns
<egresslatency>: egress latency measured in ns
PTP LocalClock
Description:
Update or show PTP current time, or set master clock ratio.
Syntax:
PTP LocalClock <clockinst> [update|show|ratio] [<clockratio>]
Parameters:
<clockinst>: clock instance number [0..3]
update|show|ratio: PTP local clock
update: The local clock is synchronized to the eCos system clock
show: The local clock current time is shown
ratio: Set the local master clock frequency ratio in units of 0,1 PPB
(ratio > 0 => faster clock, ratio < 0 => slower clock)
<clockratio>: [-10.000.000..+10.000.000] Clock frequency ratio in 0,1 PPB.
PTP Filter
Description:
Set or show PTP clock filter data.
Syntax:
PTP Filter <clockinst> [<def_delay_filt>] [<period>] [<dist>]
Parameters:
<clockinst>: clock instance number [0..3]
<def_delay_filt>: [1..6] Log2 of timeconstant in delay filter.
<period>: [1..1000] Measurement period in number of sync events.
Note: In configurations with Timestamp enabled PHYs, the period is autom atically increased, if (period*dist
< SyncPackets pr sec/4), i.e. max 4 adjustments are made pr sec.
<dist>: [1..10] Distance between servo update n number of measurement periods, if Distance is 1 the offset is averaged over
the 'period', if Distance is >1 the offset is calculated using 'min' offset.
