What is zhoneOltConfigLoopback?

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5504.5.12.1.2.1.21
snmpwalk -v2c -c public <target> ZhoneAPON-MIB::zhoneOltConfigLoopback

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5504.5.12.1.2.1.21.1
snmpget -v2c -c public <target> ZhoneAPON-MIB::zhoneOltConfigLoopback.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.5504.5.12.1.2.1.21.1 i <value>
