What is adnFirstIfIndex?
This OID contains the interface index (ifIndex) of the first interface in the device's interface list. Network engineers use this to locate the starting point when iterating through the interface table or to group related interfaces in their monitoring dashboards. For example, a value of 1 indicates that the first interface in the system has ifIndex 1, which is typically the management port.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.637.3.1.5.19.1.1 snmpwalk -v2c -c public <target> ADN-MIB::adnFirstIfIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.637.3.1.5.19.1.1.1 snmpget -v2c -c public <target> ADN-MIB::adnFirstIfIndex.1
