What is ifConnectorPresent?

This read-only TruthValue reports whether the interface's sub-layer has an actual physical connector, true(1), or does not, false(2). Admins use it to distinguish real, cabled ports from purely logical or internal interfaces when building an inventory or wiring diagram from SNMP data. For example, a physical copper Ethernet port reports ifConnectorPresent as true(1), while a loopback or VLAN interface on the same device reports false(2).

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.31.1.1.1.17
snmpwalk -v2c -c public <target> IF-MIB::ifConnectorPresent

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.31.1.1.1.17.1
snmpget -v2c -c public <target> IF-MIB::ifConnectorPresent.1

SNMPv3 example:

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