show network-clock gptp

show network-clock gptp {default-set | current-set | parent-set | time-properties-set}

Description

Displays global gPTP configuration and data.

Syntax Description

default-set Displays this switch‘s native time capabilities.
current-set Displays this switch‘s state relative to the grandmaster system.
parent-set Displays the upstream (i.e., toward the grandmaster) system‘s parameters.
time-properties-set Displays the grandmaster‘s parameters.

Default

N/A.

Usage Guidelines

Use this command to display whether gPTP is enabled in the switch and the ports on which gPTP is enabled.

Example

# show network-clock gptp   
gPTP status         : Enabled
BMCA                : Off
Static slave port   : None 
gPTP enabled ports  : *1m     *21d    *22d    *47d    
 
Flags:        (*) Active,  (!) Administratively disabled,
              (d) Disabled gPTP port role, (m) Master gPTP port role,
              (p) Passive gPTP port role,  (s) Slave gPTP port role
