What is acTrunkISDNNfasInterfaceId?

This unsigned 8-bit value uniquely identifies a trunk within an NFAS group for coordinated signaling. Operators assign unique IDs when bundling multiple T1/E1 lines for shared D-channel control. For example, setting sequential values (0, 1, 2) identifies three trunks in one NFAS group.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5003.9.10.9.1.1.3.2.1.1.2
snmpwalk -v2c -c public <target> AC-PSTN-MIB::acTrunkISDNNfasInterfaceId

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5003.9.10.9.1.1.3.2.1.1.2.1
snmpget -v2c -c public <target> AC-PSTN-MIB::acTrunkISDNNfasInterfaceId.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.5003.9.10.9.1.1.3.2.1.1.2.1 i <value>
