rs232SyncPortClockSource

Module: RS-232-MIB

OID (symbolic): RS-232-MIB::rs232SyncPortClockSource

OID (numeric): 1.3.6.1.2.1.10.33.4.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Source of the port's bit rate clock. 'split' means the tranmit clock is internal and the receive clock is external.

What is rs232SyncPortClockSource?

Sets where this synchronous port derives its bit-rate clock: internal(1) uses the device's own clock, external(2) takes clocking from the far end, and split(3) transmits on an internal clock while receiving on an external one -- a setting admins must get right to avoid clock-slip errors on leased lines.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.33.4.1.2
snmpwalk -v2c -c public <target> RS-232-MIB::rs232SyncPortClockSource

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.10.33.4.1.2.1
snmpget -v2c -c public <target> RS-232-MIB::rs232SyncPortClockSource.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.10.33.4.1.2.1 i <value>
