ds3TransmitClockSource

Module: ACMIB

OID (symbolic): ACMIB::ds3TransmitClockSource

OID (numeric): 1.3.6.1.4.1.1751.2.18.2.3.1.5

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. 'cardFreeRun' indicates that a local oscillator on the I/O card is used as the transmit clock. 'adaptiveTiming' indicates that the adaptive clocking mechanism is used

What is ds3TransmitClockSource?

This OID selects where the DS3 transmit clock originates: loopTiming (recover from receive clock), localTiming (on-board source), cardFreeRun (card oscillator), or adaptiveTiming. Network engineers use this to maintain clock synchronization across the network. Setting it to loopTiming locks the transmit clock to the incoming signal, preventing clock drift.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.3.1.5
snmpwalk -v2c -c public <target> ACMIB::ds3TransmitClockSource

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.3.1.5.1
snmpget -v2c -c public <target> ACMIB::ds3TransmitClockSource.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.2.3.1.5.1 i <value>
