17.15. SNMP

You can find the SNMP Settings at Services → SNMP.

SNMP SNMP User

The Simple Network Management Protocol lets you collect and organize information about the VT AIR from other devices.

At general you can enable or disable the whole service and define on which interface it’s running. The port is 161 by default. System location and system contact have placeholder words and can also be changed. The read community string is public by default and can be left blank to disable read access.

The write community string is disabled by default. You can only write to VT AIR OIDs not to general system OIDs.

For SNMPv3 multiple users can be created with the parameters username, access rights, password, hash and encryption algorithm.

SNMP Traps

At the bottom of the page SNMP traps can be enabled. Select whether the trap should be for V1 and or V2 and an information request shall be sent.

You can create multiple custom traps with a name, OID, options and expression. Also multiple trap servers with an IP address and port can be specified, together with a community string.
