Parameters ptp — configures the PTP clock to use PTP as the frequency source
ssu — configures the PTP clock to use the SSU as the frequency source
local-priority
Syntax local-priority priority
no local-priority
Context config>system>ptp>clock
config>system>ptp>clock>port
Description This command configures the local priority used to choose between PTP masters in the best
master clock algorithm (BMCA). If the PTP profile is set to ieee1588-2008 or itu-telecom-
freq, this parameter is ignored. The priority of the port or local clock can only be configured
if the PTP profile is set to g8275dot1-2014. The value of the highest priority is 1 and the value
of the lowest priority is 255.
The no form of this command returns the configuration to the default value.
Default 128
Parameters priority — specifies the local priority for choosing the PTP master for the BMCA; this
parameter is only relevant when the PTP profile is set to g8275dot1-2014
Values 1 to 255
log-anno-interval
Syntax log-anno-interval log-anno-interval
no log-anno-interval
Context config>system>ptp>clock
config>system>ptp>clock>ptp-port
Description This command configures the announce message interval used for unicast and multicast
messages.
For unicast messages, this command defines the announce message interval that is
requested during unicast negotiation to any peer. This controls the announce message rate
sent from remote peers to the local node. It does not affect the announce message rate that
may be sent from the local node to remote peers. Remote peers may request an announce
message rate anywhere within the acceptable grant range.
For multicast messages on PTP Ethernet ports, this command configures the message
interval used for announce messages transmitted by the local node.
