I think that I found a possible solution for this. OID 188.8.131.52.184.108.40.206.220.127.116.11.1.3 is "vtpDatabaseLocalMode(3)". The description for this OID is as follows:
The local VTP mode for a particular database type
in this administrative domain.
- 'client' indicates that the local system is acting
as a VTP client of the database type.
- 'server' indicates that the local system is acting
as a VTP server of the database type.
- 'transparent' indicates that the local system does
not generate or listen to VTP messages of this
database type , but forwards
messages. This mode can also be set by the device
itself when the size of database is too large for it
to hold in DRAM.
- 'off' indicates that the local system does not
generate , listen to or forward any VTP messages
of this database type.
The default mode is 'client' for the database type
known to the local device and 'transparent' for the
unknown database type.
This is exactly what I am looking for, but when I try to "Test" it against my core switch, I get a "The OID is not supported" message. Any chance that this can be added to the MIB database?
