What is nwAppnExtIfPortName?

This read-only string (1-8 characters) gives a user-friendly name for this router port, as opposed to a raw index number. Admins rely on this name in configuration and troubleshooting screens instead of memorizing numeric ifIndex values. A port might display as WAN1 here, which is far easier for an admin to reference in a trouble ticket than its numeric index.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.2.1.2
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnExtIfPortName

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.2.1.2.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnExtIfPortName.1
