nbsEusmPortSmartLoopbackSwap

Module: NBS-EUSM-MIB

OID (symbolic): NBS-EUSM-MIB::nbsEusmPortSmartLoopbackSwap

OID (numeric): 1.3.6.1.4.1.629.202.2.1.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description:

What is nbsEusmPortSmartLoopbackSwap?

Controls whether the port swaps the source and destination MAC addresses (and likely IP addresses) on frames it loops back during a Smart Loopback test, so the reflected frame appears to come from the original sender rather than being a raw echo; the source DESCRIPTION is empty, so this reading is inferred from the object name and its on/off syntax.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.629.202.2.1.1.3
snmpwalk -v2c -c public <target> NBS-EUSM-MIB::nbsEusmPortSmartLoopbackSwap

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.629.202.2.1.1.3.1
snmpget -v2c -c public <target> NBS-EUSM-MIB::nbsEusmPortSmartLoopbackSwap.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.629.202.2.1.1.3.1 i <value>
