2 Community Strings or passwords can be max 19 characters long. Valid characters are A-Z, a-z, 0-9 and special characters ~@#%^&_-+=:,. Do not use any other characters.
“Authentication and Warmstart Trap Receiver IP” field: Enter NMS IP address (TRAP host or manager) that will receive start-up TRAP messages.
“Heartbeat Trap Repeat Rate” field: Enter how often (number of minutes 0-10) the “heartbeat”, control TRAP message, will be resent to the receiver. Enter “0” to disable
sending “heartbeat” messages.
“Read Community String” field: Enter a password

for the SNMP agent’s Read access level. Default password is “public” (case sensitive). Network devices issuing the SNMP
GET command must be configured with this password.
“Write Community String” field: Enter a password for the SNMP agent’s Write access level. Default password is “public” (case sensitive). Network devices issuing the SNMP
SET command must be configured with this password.
About Community Strings
You can regard SNMP agents (network devices) that send TRAPs as “clients”, and network devices that receive TRAPs and poll devices (issue GETs and SETs) as “servers”.
The Community String is like a password that the “server” device issues to the “client” device during a remote query (e.g. a GET or SET command). Both the “server” and
“client” devices have to use the same password.
Most network devices implement different levels of SNMP access (e.g. Read, Write, etc.) each with its password or community string.

About Eltek Valere’s SNMP MIB Files
The Eltek Valere’s device specific MIB files
4
(Management Information Base) contain device description data, which is used by other SNMP requester devices in the Network
Management System (NMS).
For acronym descriptions, refer to chapter “Glossary”, page
44 .
The MIB files are in the plain-text, DOS End-of-Line format, and conform to the ASN1 coding syntax.
Eltek Valere’s SNMP compliant devices are described in one or several MIB files, which are required for configuration of the Network Management System (NMS).
There are 3 types of Eltek Valere SNMP MIB files:
The “ First-Time Installation Type ” MIB files. Describe a complete MIB tree structure (root and a branch) for Eltek Valere SNMP devices. Use this type of MIB file if
your NMS MIB tree does NOT already contain an Eltek Valere SNMP MIB tree structure.
The “ Root Type ” MIB files. Describe the Eltek Valere MIB tree base or root (no branches for SNMP devices). Use this type of MIB file if you want to use several Eltek
Valere Branch MIB files simultaneously as branches in the NMS MIB tree.
