lsLayer1AISAll
Module: CTRON-LINE-STATISTICS-MIB
OID (symbolic): CTRON-LINE-STATISTICS-MIB::lsLayer1AISAll
OID (numeric): 1.3.6.1.4.1.52.4497.21.1.11
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The number of times Layer 1 has detected an Alarm Indication Signal. This includes both qualified and unqualified Alarm Indication Signals.
What is lsLayer1AISAll?
This counter reports the total number of times Layer 1 has detected an Alarm Indication Signal on this line, including both qualified and unqualified occurrences. It gives visibility into brief upstream Blue-alarm conditions that self-cleared before qualifying, which can be an early warning sign of intermittent trouble further up the carrier network. A pattern of lsLayer1AISAll incrementing without lsLayer1AIS moving would suggest short-lived upstream signal interruptions rather than a sustained carrier outage.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4497.21.1.11 snmpwalk -v2c -c public <target> CTRON-LINE-STATISTICS-MIB::lsLayer1AISAll
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4497.21.1.11.1 snmpget -v2c -c public <target> CTRON-LINE-STATISTICS-MIB::lsLayer1AISAll.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> lsLayer1AISAll.1
