c3gServiceChangedNotifEnabled

Module: CISCO-WAN-3G-MIB

OID (symbolic): CISCO-WAN-3G-MIB::c3gServiceChangedNotifEnabled

OID (numeric): 1.3.6.1.4.1.9.9.661.1.1.1.22

Description: This object is used to enable/disable the generation of service changed notification c3gServiceChangedNotif.

What is c3gServiceChangedNotifEnabled?

This read-write TruthValue enables or disables the c3gServiceChangedNotif notification, which fires when the modem's service type changes (as tracked by c3gCurrentServiceType). An admin enables this to catch service downgrades or upgrades, such as an LTE connection falling back to 3G, as they happen rather than discovering them only when reviewing logs later. For example, with this enabled, the NOC would receive a trap the moment a normally LTE-connected router's service type flips to 3G during a tower outage.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.661.1.1.1.22
snmpwalk -v2c -c public <target> CISCO-WAN-3G-MIB::c3gServiceChangedNotifEnabled

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.661.1.1.1.22.1
snmpget -v2c -c public <target> CISCO-WAN-3G-MIB::c3gServiceChangedNotifEnabled.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.661.1.1.1.22.1 s <value>
