What is swPTPFMAnnounceMsg?
A read-only counter of Announce messages received from this foreign (candidate but not currently selected) master on this port. Admins watch this to see how actively a competing PTP master is being heard, useful when investigating why the Best Master Clock algorithm might switch masters.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.94.1.6.1.1.3 snmpwalk -v2c -c public <target> PTP-MIB::swPTPFMAnnounceMsg
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.94.1.6.1.1.3.1 snmpget -v2c -c public <target> PTP-MIB::swPTPFMAnnounceMsg.1
