swPTPBoundaryClockIdentity
Module: PTP-MIB
OID (symbolic): PTP-MIB::swPTPBoundaryClockIdentity
OID (numeric): 1.3.6.1.4.1.171.12.94.1.4.1.1.1
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: This indicates the PTP boundary clock identity.
8-octet array, The first 3 octets of the MAC address are assigned in order to the first 3 octets of the clockIdentity. Octets with index 3 and 4 are respectively assigned hex values FF and FE. The remaining 3 octets of the MAC address are assigned in order to the last 3 octets of the clockIdentity.
What is swPTPBoundaryClockIdentity?
A read-only 8-octet clock identity for this unit's PTP boundary clock, built from the port's MAC address with FF-FE inserted in the middle per IEEE 1588 (first 3 MAC octets, then FF, FE, then the remaining 3 MAC octets). Admins use this to uniquely recognize this switch's boundary clock when reviewing PTP topology or master/slave relationships across the network.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.94.1.4.1.1.1 snmpwalk -v2c -c public <target> PTP-MIB::swPTPBoundaryClockIdentity
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.94.1.4.1.1.1.1 snmpget -v2c -c public <target> PTP-MIB::swPTPBoundaryClockIdentity.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> swPTPBoundaryClockIdentity.1
