rs232PortIndex
Module: RS-232-MIB
OID (symbolic): RS-232-MIB::rs232PortIndex
OID (numeric): 1.3.6.1.2.1.10.33.2.1.1
Node type: OBJECT-TYPE
Type: InterfaceIndex
Access: read-only
Description: The value of ifIndex for the port. By convention and if possible, hardware port numbers map directly to external connectors. The value for each port must remain constant at least from one re-initialization of the network management agent to the next.
What is rs232PortIndex?
Identifies a serial port via its ifIndex value from IF-MIB, which by convention maps directly to the port's external connector, and stays constant across agent restarts so an admin can reliably track the same physical port over time.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.33.2.1.1 snmpwalk -v2c -c public <target> RS-232-MIB::rs232PortIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.10.33.2.1.1.1 snmpget -v2c -c public <target> RS-232-MIB::rs232PortIndex.1
