address
Syntax address {01:1b:19:00:00:00|01:80:c2:00:00:0e}
no address
Context config>port>ethernet>ptp>port
Description This command allows for the specification of the mac-address to be used for the destination MAC
address of the transmitted ptp messages.
IEEE Std 1588-2008 Annex F defines two reserved addresses for 1588 messages. These are:
• 01-1B-19-00-00-00 — All except the peer delay mechanism messages.
• 01-80-C2-00-00-0E — Peer delay mechanism messages.
Both addresses are supported for reception independent of the address configured by this command.
The no form of this command sets the address to the default address.
Default address 01-1B-19-00-00-00
log-delay-interval
Syntax log-delay-interval log-interval
Context configure>system>ptp>port
Description This command configures the minimum interval used for multicast Delay_Req messages. This
parameter is applied on a per port basis. For ports in a slave state, it shall be the interval used, unless
the parent port indicates a longer interval. For a port in master state, it shall be the interval advertised
to external slave ports as the minimum acceptable interval for Delay_Req messages from those slave
ports.
It is a requirement of the 1588 standard that a port in Slave state shall check the logMessageInterval
field of received multicast Delay_Resp messages. If the value of the logMessageInterval field of those
messages is greater than the value programmed locally for the generation of Delay_Req messages, then
the Slave must change to use the greater value (i.e. longer interval) for the generation of Delay_Req
messages. This requirement is supported in the router.
The parameter is only applicable to ports and not to peers.
Default -6 for ieee1588-2008
-6 for g8265dot1-2010
-4 for g8275dot1-2014
Parameters log-interval — Specifies the Delay_Req message interval, in log form.
Values [-6 to 0]
