This command configures the switch's default-set parameters, specifically its grandmaster clock priority values that are used to elect the grandmaster clock in the network.
| priority1_value | The switch's grandmaster clock priority1 value. This is the most significant parameter used to select the grandmaster clock in the network. Lower values indicate higher priority, and 255 prevents the switch from becoming the grandmaster clock. |
| priority2_value | The switch‘s grandmaster clock priority2 value. This is one of the least significant parameters used to select the grandmaster clock in the network. Lower values indicate higher priority. |
Use this command to configure the switch's default-set parameters, specifically its grandmaster clock priority values that are used to elect the grandmaster clock in the network. The Best Master Clock Algorithm uses six parameters from each time-aware system in the network to select the grandmaster clock in the network. Priority1 is the highest precedence value; it allows users to preemptively configure which systems they prefer to be the grandmaster clock. Priority2 is a lower precedence value; it allows users to configure tiebreaker priorities.
The default priority1 values defined by IEEE 802.1AS-2011 clause 8.6.2.1 give preference to network infrastructure systems such as Extreme switches.
