What is atmSuSystemHistoryAlrIfIndex?

This OID indicates which physical port or interface experienced the alarm, with port index 0 reserved for system and configuration alarms. A network engineer uses this to pinpoint whether an alarm is port-specific or system-wide, narrowing down troubleshooting scope. For example, port index 3 means the alarm occurred on physical interface 3, while 0 indicates a system-level issue like a configuration error.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.164.12.4.1.3.1.2
snmpwalk -v2c -c public <target> ACE20-MIB::atmSuSystemHistoryAlrIfIndex

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.164.12.4.1.3.1.2.1
snmpget -v2c -c public <target> ACE20-MIB::atmSuSystemHistoryAlrIfIndex.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> atmSuSystemHistoryAlrIfIndex.1
