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:.*::ifTable
Show 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:.*::ifTable
Show 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:.*::ifTable
Show 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:.*::ifTable
Show output
SNMP table: IF-MIB::ifTable
