What is sonetPortLineSESS15Min?

This sets the 15-minute threshold for SONET line-layer severely errored seconds. An admin monitors this in conjunction with the section-layer equivalent to see whether serious errors are isolated to the immediate segment or extend further along the line layer. Severely errored seconds are generally treated as a higher-priority alarm category than ordinary errored seconds.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5812.3.5.1.21
snmpwalk -v2c -c public <target> PORT-MIB::sonetPortLineSESS15Min

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5812.3.5.1.21.1
snmpget -v2c -c public <target> PORT-MIB::sonetPortLineSESS15Min.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.5812.3.5.1.21.1 i <value>
