Message Attributes › Message Routing Codes

Message Routing Codes

One or more routing codes are usually associated with a system message. The operating system uses routing codes to deliver messages to a particular console. When a system console is generated, it is assigned one or more routing codes. Routing codes can be used to send messages to a consolidated console.

The operating system, by convention, applies certain meanings to specific routing codes. You are encouraged to work within these conventions. System-sourced messages follow these conventions.

Note: MSP and VOS3 systems support routing codes 1 through 16 only.
