•
IEEE
802.3/Ethernet.
Force state
Whether the force state is configured:
•
Yes.
•
No.
Announce interval (log mean)
Announce message sending interval (in seconds) = 2
value
(this field displays
the value for the
value
exponent).
Announce receipt time out
Timeout value for receiving announce messages. If a member node does
not receive any announce message from the master node within the
specified value, it considers the master node invalid.
Sync interval (log mean)
Sync message sending interval (in seconds) = 2
value
(this field displays the
value for the
value
exponent).
Delay request interval (log
mean)
Minimum delay request message sending interval (in seconds) = 2
value
(this
field displays the value for the
value
exponent).
Peer delay request interval
(log mean)
Peer delay request message sending interval (in seconds) = 2
value
(this field
displays the value for the
value
exponent).
Mean path delay
Mean path delay, in nanoseconds.
