hm2PtpAbsMaxOffset
Module: HM2-TIMESYNC-MIB
OID (symbolic): HM2-TIMESYNC-MIB::hm2PtpAbsMaxOffset
OID (numeric): 1.3.6.1.4.1.248.11.50.1.4.1.7
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This members value shall indicate the absolute value for the maximum offset between its parent and this node. The value is set to zero if the offset is the first time smaller than hm2PtpSyncLowerBound. Offsets bigger than +/-1 second are indicated by the maximum value.
What is hm2PtpAbsMaxOffset?
Tracks the largest absolute offset seen between this node and its PTP parent since it last dropped below hm2PtpSyncLowerBound; offsets beyond +/-1 second are reported as the maximum value, so a high reading flags a serious past sync excursion worth investigating.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.11.50.1.4.1.7 snmpwalk -v2c -c public <target> HM2-TIMESYNC-MIB::hm2PtpAbsMaxOffset
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.248.11.50.1.4.1.7.1 snmpget -v2c -c public <target> HM2-TIMESYNC-MIB::hm2PtpAbsMaxOffset.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> hm2PtpAbsMaxOffset.1
