What is rs232SyncPortClockSource?

Sets the source of this synchronous port's bit-rate clock: internal, external, or split (transmit clock internal, receive clock external), a critical setting for keeping synchronous data aligned with the attached DCE/DTE equipment.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.3.20.4.1.2
snmpwalk -v2c -c public <target> RS232-MIB::rs232SyncPortClockSource

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.3.20.4.1.2.1
snmpget -v2c -c public <target> RS232-MIB::rs232SyncPortClockSource.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.3.20.4.1.2.1 i <value>
