rs232PortIndex

Module: RFC1317-MIB

OID (symbolic): RFC1317-MIB::rs232PortIndex

OID (numeric): 1.3.6.1.2.1.10.33.2.1.1

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: A unique value for each port. Its value ranges between 1 and the value of rs232Number. 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?

A unique identifier (1 through rs232Number) for each serial port; by convention it maps directly to the port's external connector label where possible, and stays constant across agent restarts.

Examples
