SNMP Community Value

The SNMP community value, defined within the protocol, acts as a password. It

authenticates messages between the VN-Matrix 325 system and the NMS. By default, the

community string is set to public. This value can be changed, using the SNMP filter settings

panel (see figure 52) on the alarm logs page. The community string must match that in use

by the NMS; if not then it may not be possible to manage the VNC 325 device.

SNMP Trap Destination Values

The Create Trap Destination field in the SNMP filter settings panel (see figure 52) on

the alarm logs page is used to add and remove destination IP addresses for NMS servers.

Multiple destinations may be added.
