What is sonetPathPLMs?

Counts the number of seconds during which this port's path had a Payload Label Mismatch defect, detected when the STS signal label (C2 byte) doesn't match any expected value (0x00, 0x01, 0x13, 0xFC, or 0xFF). An admin treats this as a sign the path is carrying, or is expected to carry, an unrecognized or misconfigured payload type.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.4.2.3.1.10
snmpwalk -v2c -c public <target> Fore-SONET-MIB::sonetPathPLMs

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.4.2.3.1.10.1
snmpget -v2c -c public <target> Fore-SONET-MIB::sonetPathPLMs.1
