rs232AsyncPortAutobaud

Module: RS232-MIB

OID (symbolic): RS232-MIB::rs232AsyncPortAutobaud

OID (numeric): 1.3.6.1.3.20.3.1.5

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: A control for the port's ability to automatically sense input speed.

When rs232PortAutoBaud is 'enabled', a port may autobaud to values different from the set values for speed, parity, and character size. As a result a network management system may temporarily observe values different from what was previously set.

What is rs232AsyncPortAutobaud?

Enables or disables automatic input-speed sensing on this asynchronous port; when enabled, the port may lock onto a speed/parity/character-size combination different from what's configured, so a management system may temporarily see settings it didn't set.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.3.20.3.1.5
snmpwalk -v2c -c public <target> RS232-MIB::rs232AsyncPortAutobaud

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.3.20.3.1.5.1
snmpget -v2c -c public <target> RS232-MIB::rs232AsyncPortAutobaud.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.3.20.3.1.5.1 i <value>
