Check Incoming Requests

This scenario shows how to configure a user to receive incoming requests in SNMPv3. In addition, the SNMP ‘walk’ and ‘table’ commands are checked.

Test SNMP Walk

Description

A user is configured in DUT0 and the ‘walk’ command is used to check incoming requests in SNMPv3.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 10.0.0.1/24
set service snmp user USER2TEST
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 10.0.0.2/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Note

First, local and DUT1 requests are allowed when using a ‘noAuthNoPriv‘ user.

Step 3: Run command service snmp walk local-agent v3 USER2TEST oid ifTable at DUT0 and check if output matches the following regular expressions:

::ifDescr\.1 = STRING: "?lo"?

Test SNMP Table

Description

A user is configured in DUT0 and the ‘table’ command is used to check incoming requests in SNMPv3.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 10.0.0.1/24
set service snmp user USER2TEST
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 10.0.0.2/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Note

First, local and DUT1 requests are allowed when using a ‘noAuthNoPriv‘ user.

Step 3: Run command service snmp table local-agent v3 USER2TEST oid ifTable at DUT0 and check if output matches the following regular expressions:

SNMP table:.*::ifTable

Show output

Note

Finally, when using an ‘authPriv‘ user, DUT1 requests are not allowed until the correct parameters are given in the request.

Step 9: Modify the following configuration lines in DUT0 :

set service snmp user USER2TEST privacy encrypted-password U2FsdGVkX19TcK5AJRJ4ToCLK3slAT4+gV517eSjSaI=
set service snmp user USER2TEST privacy protocol AES

Step 10: Run command service snmp table local-agent v3 USER2TEST oid ifTable at DUT0 and check if output matches the following regular expressions:

SNMP table:.*::ifTable
