Check Listening Addresses
This scenario shows how to restrict the addresses used to listen for incoming requests in SNMPv3. In addition, the SNMP ‘walk’ and ‘table’ commands are checked.
Test SNMPv3
Description
Listening addresses are configured for a user in DUT0, and the ‘walk’ and ‘table’ commands are used to check incoming requests in SNMPv3 .
Scenario
Step 1: Set the following configuration in DUT0:
set interfaces dummy dum0 address 20.0.0.1/24 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
Initially, local and DUT1 requests are allowed, since the ‘listen‘ field is set for all interfaces by default.
Step 3: Run command service snmp walk local-agent v3 USER2TEST oid ifTable at DUT0 and check if output matches the following regular expressions:

Note
After configuring SNMP to listen on the local address, local requests should be allowed, but not DUT1 requests.
Step 7: Modify the following configuration lines in DUT0:
set interfaces dummy dum1 address 127.0.0.1/24 set service snmp listen address 127.0.0.1
Step 8: Run command service snmp walk local-agent v3 USER2TEST oid ifTable at DUT0 and check if output matches the following regular expressions:

Step 15: Run command service snmp table local-agent v3 USER2TEST oid ifTable at DUT0 and check if output does not match the following regular expressions:

snmptable: Timeout (Sub-id not found: (top) -> ifTable)
Step 16: Run command service snmp table remote-agent 10.0.0.1 v3 USER2TEST oid ifTable at DUT1 and check if output matches the following regular expressions:

Note
After configuring SNMP to listen on the ‘20.0.0.1‘ address, neither local nor DUT1 requests should be allowed.
Step 17: Modify the following configuration lines in DUT0:
delete service snmp listen address 10.0.0.1 set service snmp listen address 20.0.0.1
Step 18: Run command service snmp walk local-agent v3 USER2TEST oid ifTable at DUT0 and check if output does not match the following regular expressions:
::ifDescr\.1 = STRING: "?lo"?Show output
snmpbulkwalk: Timeout (Sub-id not found: (top) -> ifTable)
Step 19: Run command service snmp walk remote-agent 10.0.0.1 v3 USER2TEST oid ifTable at DUT1 and check if output does not match the following regular expressions:
::ifDescr\.1 = STRING: "?lo"?Show output
snmpbulkwalk: Timeout (Sub-id not found: (top) -> ifTable)
Step 20: Run command service snmp table local-agent v3 USER2TEST oid ifTable at DUT0 and check if output does not match the following regular expressions:
SNMP table:.*::ifTableShow output
snmptable: Timeout (Sub-id not found: (top) -> ifTable)
Step 21: Run command service snmp table remote-agent 10.0.0.1 v3 USER2TEST oid ifTable at DUT1 and check if output does not match the following regular expressions:
SNMP table:.*::ifTableShow output
snmptable: Timeout (Sub-id not found: (top) -> ifTable)
