SNMP - How to configure SNMP

For monitoring the state of Netstar you can enable SNMP protocol.

In order to enable SNMP on Netstar follow the steps below. No license is required for SNMP operation.

1) Upload MIB table to Netstar. MIB table is stored in this directory c:\Program Files (x86)\2N TELEKOMUNIKACE\2N NetStar\NetStar Admin Tool 4.2.0\

    Select "Internet" option and click right to add MIB table:

Now Netstar is able to send all the traps.

2) If you need to send only certain traps, add a new rule in the filter:

3) Select required trap from the list

Please note, that off check "Exception" field then Netstar will be sending all the traps but selected one.If this field is unchecked, Netstar will send only selected trap.

For example, you need to monitor operation of E1 port. Select OID


In PRI stack set one of the  parameters "Inactive L1 as error", "Disconnected L2 as error" (depends on which layer of DSS1 should be monitored)

4) Now we need to set IP address of the client who will send requests to Netstar.

5) Configure client IP address, type of SNMP protocol, filter and specify the user. By default there is one user "Public" with all the rights. If you want to have more users but with different rights, please refer the manual.
