SNMP Statement

The Simple Network Management Protocol (SNMP) is a not a routing protocol but a network management protocol. The snmp statement controls whether GateD tries to contact the SNMP Multiplexing daemon to register supported variables. The SNMP daemon (usually smuxd) must be run independently. The snmp statement only controls whether GateD keeps the management software apprised of its status.

GateD communicates with the SNMP daemon via the SMUX protocol that is described in RFC 1227.

The SNMP statement

snmp yes | no | on | off [ { port port ; debug ; traceoptions traceoptions ; } ] ;

Reporting is enabled by specifying yes or on and disabled with no or off. The default is on.

port port

By default, the SMUX daemon listens for requests on port 199. GateD can be configured to try to contact the SMUX daemon on a different port by explicitly specifying the port.

debug

Specifying this option enables debugging of the ISODE SMUX code. The default is debugging disabled.

traceoptions trace_options

Specifies the tracing options for SMUX. (See Trace Statements and the SMUX specific tracing options below.)

Tracing options

There are no SNMP-specific trace options. SNMP requests received via the SMUX protocol from the SNMP daemon are not handled quite like packets. The detail, send, and recv options are not supported.

receive

SNMP requests received from the SMUX daemon and the associated responses.

register

Protocol requests to register variables.

resolve

Protocol requests to resolve variable names.

trap

SNMP trap requests from protocols.
