cncNotificationOnChange

Module: CISCO-ATM-NETWORK-CLOCK-MIB

OID (symbolic): CISCO-ATM-NETWORK-CLOCK-MIB::cncNotificationOnChange

OID (numeric): 1.3.6.1.4.1.9.9.121.1.1.2

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: The value of this object determines whether a notification should be generated due to a change in the device's root clock source (given by the value of cncRootClockSource). A value of 'true' enables the generation of notifications; 'false' disables notification generation.

What is cncNotificationOnChange?

This read-write flag controls whether the device sends a notification (trap) when its root clock source changes, allowing administrators to be alerted to timing source failovers.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.121.1.1.2
snmpwalk -v2c -c public <target> CISCO-ATM-NETWORK-CLOCK-MIB::cncNotificationOnChange

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.121.1.1.2.1
snmpget -v2c -c public <target> CISCO-ATM-NETWORK-CLOCK-MIB::cncNotificationOnChange.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.121.1.1.2.1 s <value>
