Check Incoming Requests
This scenario shows how to configure a user to receive incoming requests in SNMPv3 using VRFs.
In addition, the SNMP walk and table commands are checked.
Test SNMP Walk With VRFs
Description
Using VRFs, 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 interfaces ethernet eth0 vrf A set service snmp user USER2TEST set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0' set system vrf A
Step 2: Set the following configuration in DUT1 :
set interfaces ethernet eth0 address 10.0.0.2/24 set interfaces ethernet eth0 vrf B set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0' set system vrf B
Note
First, remote walk requests shouldn’t work because no information has been specifed in DUT1 about where to route the requests.
Step 3: 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: Unknown engine ID (Sub-id not found: (top) -> ifTable) (Network is unreachable)
Note
Remote walk requests also shouldn’t work because no information has been specified in DUT0 about where to route responses.
Step 4: Run command service snmp walk remote-agent 10.0.0.1 v3 USER2TEST vrf B 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)
Note
After setting the VRF in DUT0, remote walk requests shouldn’t work until information on where to route the requests is specified in DUT1.
Step 5: Modify the following configuration lines in DUT0 :
set service snmp local-vrf A
Step 6: 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: Unknown engine ID (Sub-id not found: (top) -> ifTable) (Network is unreachable)
Step 7: Run command service snmp walk remote-agent 10.0.0.1 v3 USER2TEST vrf B oid ifTable at DUT1 and check if output matches the following regular expressions:
::ifDescr\.1 = STRING: "?lo"?Show output

Test SNMP Table With VRFs
Description
Using VRFs, 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 interfaces ethernet eth0 vrf A set service snmp user USER2TEST set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0' set system vrf A
Step 2: Set the following configuration in DUT1 :
set interfaces ethernet eth0 address 10.0.0.2/24 set interfaces ethernet eth0 vrf B set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0' set system vrf B
Note
First, remote table requests shouldn’t work because no information has been specified in DUT1 about where to route the requests.
Step 3: 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: Unknown engine ID (Sub-id not found: (top) -> ifTable) (Network is unreachable)
Note
Remote table requests should also not work because no information has been specified in DUT0 about where to route responses.
Step 4: Run command service snmp table remote-agent 10.0.0.1 v3 USER2TEST vrf B 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)
Note
After setting the VRF in DUT0, remote table requests shouldn’t work until the information on where to route the requests is specified in DUT1.
Step 5: Modify the following configuration lines in DUT0 :
set service snmp local-vrf A
Step 6: 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: Unknown engine ID (Sub-id not found: (top) -> ifTable) (Network is unreachable)
Step 7: Run command service snmp table remote-agent 10.0.0.1 v3 USER2TEST vrf B oid ifTable at DUT1 and check if output matches the following regular expressions:
SNMP table:.*::ifTableShow output
