Announce Receipt Timeout – Sets the transmit timeout for PTP
◆
announcement messages. This parameter indicates the number of PTP
announce message intervals which have to expire without the receipt of
a announce message before the session times out. (Range: 2-10;
Default: 3)
Log Min Pdelay Req Interval – Sets the peer delay request message
◆
transmit interval. This parameter indicates the minimum interval
between peer delay request messages used to measure the link delay
between two clock ports implementing the peer-to-peer delay
mechanism. (Range: 0-5 in log base 2; Default: 0)
The log base 2 settings equate to the following values:
0 – 1 packet every second
■
1 – 1 packet every 2 seconds
■
2 – 1 packet every 4 seconds
■
3 – 1 packet every 8 seconds
■
4 – 1 packet every 16 seconds
■
5 – 1 packet every 32 seconds
■
This parameter is only applicable for interfaces which are set to use the
peer-to-peer delay mechanism.
◆ Log Min Delay Req Interval – Sets the delay request message
transmit interval. This parameter indicates the minimum interval
between delay request messages sent by a slave clock to a specific port
on the master clock. (Range: 0-5 in log base 2)
The log base 2 settings equate to the following values:
0 – 1 packet every second
■
1 – 1 packet every 2 seconds
■
2 – 1 packet every 4 seconds
■
3 – 1 packet every 8 seconds
■
4 – 1 packet every 16 seconds
■
5 – 1 packet every 32 seconds
■
This value is determined and advertised by a master clock based on its
ability to process delay request message traffic.
◆ Port Release – Returns a port to PTP enabled state after having been
disabled by a PTP management message.
Check the "Port State" field displayed by the Show PTP Information –
Port Data page to see if a port has been disabled by a PTP management
message.
