Description:

What is nbsEusmPortSmartLoopbackAction?

Configures the Smart Loopback test mode for this port: off disables it, all loops back every frame, onDA/onVid/onBoth loop back only frames matching a specific destination MAC/VLAN/both, and mac is a special mode available only on User-Ports; the source DESCRIPTION is empty, so this reading is inferred from the object name, its enumeration, and the inline comment on the mac(7) value.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.629.202.2.1.1.2
snmpwalk -v2c -c public <target> NBS-EUSM-MIB::nbsEusmPortSmartLoopbackAction

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.629.202.2.1.1.2.1
snmpget -v2c -c public <target> NBS-EUSM-MIB::nbsEusmPortSmartLoopbackAction.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.629.202.2.1.1.2.1 i <value>
