Check Information Restriction
This scenario shows how to configure a view to restrict information for incoming requests in SNMPv3. In addition, the SNMP ‘walk’ and ‘table’ commands are checked.
Test SNMPv3
Description
A restricted view is 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 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 there are no restrictions 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 adding a view that excludes the ‘1.3.6.1.2.1.2‘ oid, retrieving information about interfaces shouldn’t be allowed.
Step 7: Modify the following configuration lines in DUT0 :
set service snmp user USER2TEST view NOIFCS set service snmp view NOIFCS oid 1.3.6.1.2.1.2 type excluded
Step 8: 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
IF-MIB::ifTable = No more variables left in this MIB View (It is past the end of the MIB tree)
Step 9: 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
IF-MIB::ifTable = No more variables left in this MIB View (It is past the end of the MIB tree)
Step 10: 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
IF-MIB::ifTable: No entries
Step 11: 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
IF-MIB::ifTable: No entries
