What is sonetPathLOPs?

Counts the number of seconds during which this port experienced a path Loss Of Pointer, detected when no normal pointer value appears for eight consecutive frames and cleared after three consecutive normal frames. An admin treats a nonzero count here as a serious path-layer synchronization failure.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.4.2.3.1.6
snmpwalk -v2c -c public <target> Fore-SONET-MIB::sonetPathLOPs

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.4.2.3.1.6.1
snmpget -v2c -c public <target> Fore-SONET-MIB::sonetPathLOPs.1
