Querying the SNS firewall in SNMP
The following is an example of a query command that makes it possible to test the function of the SNMPv3 configuration on an SNS firewall that uses the configuration parameters mentioned earlier:
snmpwalk -v 3 -u <user_snmp > -l authPriv -a SHA -x AES <ip_admin_SNS>
The SNS firewall must send back OIDs and their values.
WARNING
Passwords should preferably be put in the configuration file instead of the command line, then deleted.
The snmpwalk utility is available on many platforms, and makes it possible to query the SNMP service on an SNS firewall. Details of the parameters used in this example:
-v 3 | Corresponds to the version of the SNMP protocol used. |
-u <user_smp> |
Corresponds to the User name parameter entered on the SNS firewall. |
-l authPriv | Indicates that the SNMP query is encrypted and authenticated |
-a SHA |
Specifies the type of hash function used for authentication. The password used must be placed in the configuration file. The variable to add is def- AuthPassphrase. |
-x AES |
Indicates the algorithm used for encryption. The password used must be placed in the configuration file. The variable to add is defPrivPassphrase. |
