  • 4 minutes to read

    • The ServiceNow Discovery application uses the Next-Generation Juniper Network Firewall discovery pattern to find Juniper network firewalls. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    The discovery pattern uses a set of SNMP calls to find the Juniper network firewalls. Discovery uses the pattern to run horizontal discovery.

    Juniper Network Firewall data model

    The Next-Generation Juniper Network Firewall pattern introduces the following CI classes that are part of the Juniper firewall data model.

    Table 1. CI class hierarchy
    CI class Extends from
    Firewall Device [cmdb_ci_firewall_device] IP Firewall [cmdb_ci_ip_firewall]
    Juniper Firewall Device [cmdb_ci_firewall_device_juniper] Firewall Device [cmdb_ci_firewall_device]
    Firewall Cluster [cmdb_ci_firewall_cluster] Cluster [cmdb_ci_cluster]
    Juniper Firewall Cluster [cmdb_ci_firewall_cluster_juniper] Firewall Cluster [cmdb_ci_firewall_cluster]

    Firewall Manager [cmdb_ci_firewall_manager] Configuration Item [cmdb_ci]
    Firewall Security Policy [cmdb_ci_firewall_security_policy] Configuration Item [cmdb_ci]

    Prerequisites

    • Ensure that your network firewall device has SNMP access.
    • On the ServiceNow instance, configure SNMP credentials.
    • Add the SNMP system OID record for the Juniper device to the ServiceNow instance. Update the following:
      • Classifier: Juniper Firewall
      • Class: Juniper Firewall Device
    Deploy the pattern as follows:
    1. Download and install the CMDB CI Class Models: Release 1.10.0 from the ServiceNow Store. The app adds the new CMDB classes required for network firewall discovery. For more information, see Firewall extension classes.
    2. Download and install the discovery pattern from the ServiceNow Store.
    3. Sync the pattern with the appropriate MID Server.
