Subject to errors and changes

If no SNMP communication takes place over a period of 5
minutes during an open session, the device unilaterally ends
the session and all changes are cancelled.

Opening an SNMP session has priority over an

HTTP login. This means: A user with Config
or Administrator rights loses his browser access as

soon as an SNMP session is opened.

The description for the individual SNMP variables, OIDs etc. can
be found in the Private-MIB.
