Module: IEEE8021-AS-MIB

Access: read-write
Description: Most-significant priority declaration in the execution of the best master clock algorithm. Lower values take precedence. The value of priority1 shall be 255 for a time-aware system that is not grandmaster-capable. The value of priority1 shall be less than 255 for a time-aware system that is grandmaster-capable. The value 0 shall be reserved for future management use, i.e., the valueof priority1 shall be set to 0 only via management action, and shall not be specified as a default value by a user of this standard. In the absence of a default value set by a user of this standard, the default value shall be set as below: a) system type of network infrastructure time-aware system to value 246; b) portable time-aware system, 250; c) other time-aware systems, 248.
What is ieee8021AsDefaultDSPriority1?
The most-significant tie-breaking priority a device advertises in the best master clock election; lower numbers win, and 255 marks a device that must never become grandmaster. Admins tune this (e.g. lower it on an authoritative clock) to force a specific switch to become the time master.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.20.1.1.6 snmpwalk -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsDefaultDSPriority1
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.20.1.1.6.1 snmpget -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsDefaultDSPriority1.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.111.2.802.1.1.20.1.1.6.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ieee8021AsDefaultDSPriority1.1
