oc3TransmitClockSource

Module: ACMIB

OID (symbolic): ACMIB::oc3TransmitClockSource

OID (numeric): 1.3.6.1.4.1.1751.2.18.2.6.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The source of Tranmit Clock. 'loopTiming' indicates that the recovered re- ceive clock is used as the transmit clock.

'localTiming' indicates that a local clock source is used.

What is oc3TransmitClockSource?

This OID determines whether the OC3 port derives its outgoing clock signal from the incoming recovered clock (loop timing) or from its own local oscillator (local timing). Administrators adjust this to synchronize timing across networked devices and prevent clock drift that degrades bit error rates and link quality. Setting it to 'loopTiming' makes the port slave its transmit clock to the received clock signal, useful for locking to a remote device's timing.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.6.1.3
snmpwalk -v2c -c public <target> ACMIB::oc3TransmitClockSource

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.6.1.3.1
snmpget -v2c -c public <target> ACMIB::oc3TransmitClockSource.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.2.6.1.3.1 i <value>
