- -- the SUBAGENT MIB
-
- -- The MIB objects are implemented by the local SNMP agent
-
- -- This MIB is based on some experience with both DPI and SMUX
- -- subagents. As you can see, some of the ideas come from the
- -- original SMUX MIB (RFC1227) by Marshall Rose.
- -- We try to define a subagent MIB that represents subagents
- -- using different protocols.

-
- saDefaultTimeout OBJECT-TYPE
- SYNTAX INTEGER -- (1..saMaxTimeout)
- -- UNITS "seconds"
- ACCESS read-write
- STATUS mandatory
- DESCRIPTION
- "The default timeout (in seconds) that this agent
- waits for a response from a SubAgent. This value
- is used if a timeout value is not specified for
- the subtree nor for the subagent that exports
- the subtree."
- -- DEFVAL { 5 }

- -- so quite big already
- -- UNITS "seconds"
- ACCESS read-write
- STATUS mandatory
- DESCRIPTION

- ACCESS read-write
- STATUS mandatory
- DESCRIPTION
- "Controls if multiple instances of a sub-agent (as
- identified by the sub-agent Identifier) are allowed.
-
- Setting this object to the value no(2) will prevent
- (new) duplicate sub-agentIDs. However, if any
- duplicates exist at that point in time, the agent
- will not remove them. That is considered a manager
- responsibility."

- DESCRIPTION

-
- The only value that can be set is invalid(2).
- This can only be done if the status is not already
- in a ClosedSomething status.
-
- Setting this object to the value invalid(2) has
- the effect of invalidating the entry upon which
- the agent will close the connection and turn it
- to status closedByManager(7).
-
- It is an implementation specific matter if an
