priority2
Syntax priority2 priority
no priority2
Context config>system>ptp
Description This command configures the priority2 value of the local clock. This parameter is only used when the
profile is set to ieee1588-2008 or g8275dot1-2014. The parameter is ignored when any other profile is
selected.
This value is used by the Best Master Clock algorithm to determine which clock should provide timing
for the network.
Note: This value is used for the value to advertise in the Announce messages and for local clock value
in data set comparisons.
The no form of the command reverts to the default configuration.
Default 128
Parameters priority — Specifies the value of the priority2 field.
Values 0 to 255
profile
Syntax profile {g8265dot1-2010 | ieee1588-2008 | g8275dot1-2014}
Context config>system>ptp
Description This command configures the profile to be used for the internal PTP clock. It defines the Best Master
Clock Algorithm (BMCA) behavior.
The profile cannot be changed unless PTP is shutdown.
When you change the profile, the domain changes to the default value for the new profile. The clock-
type is restricted based on the profile. If the profile is ieee1588-2008 then the clock-type is not
restricted. If the profile is g8265dot1-2010 then the clock type may only be ordinary slave or ordinary
master; boundary clock is not allowed. If the profile is g8275dot1-2014 then the clock type may only
be boundary clock; ordinary slave and ordinary master is not allowed.
When you change the profile, if any of the command parameters are set to default for the original
profile, then the parameter will be changed to the default for the new profile. This applies to the
following:
• log-anno-interval set for the clock
• log-sync-interval set for a peer or a port
• log-delay-interval set for a port
