SNMP Community
The value in the SNMP Community field acts as a password. It is used to authenticate
messages between the VN‑Matrix 250 system and the network management system
(NMS). By default, the SNMP Community field is set to public. The SNMP Community
string must match that in use by the NMS; if not, it may not be possible to manage the
VN‑Matrix250 device.
SNMP Trap Destinations
The Filter Settings dialogue on the Alarm Logs page is used to add and remove destination
IP addresses for NMS servers.
Figure 24. Filter Settings Section of the Alarm Logs Page
The IP address of the NMS should be entered in the Create Trap Destination field.
Multiple destinations may be added, one at a time.
Upgrade tab
To access the Upgrade tab, you must first select a device from the Device List and,
when the Device tab opens, click the Upgrade Tab. However, whether you navigate to the
Upgrade tab from an encoder or a decoder, the functionality is the same.
Figure 25. Upgrade Tab
The Upgrade screen supports the network based upgrade of the device firmware (see
Upgrading Firmware on page 87).
