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 ethernet eth0 address 10.0.0.1/24 set interfaces dummy dum0 address 20.0.0.1/24 set service snmp user USER2TEST
Step 2: Set the following configuration in DUT1:
set interfaces ethernet eth0 address 10.0.0.2/24
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 ‘10.0.0.1‘ address, DUT1 requests should be allowed, but not local requests.
Step 12: Set the following configuration in DUT0:
del interfaces dummy dum1 address 127.0.0.1/24 del service snmp listen address 127.0.0.1 set service snmp listen address 10.0.0.1
Step 13: Run command service snmp walk local-agent v3 USER2TEST oid ifTable at DUT0 and check if output does not match 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: Set the following configuration in DUT0:
del 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)
