## Summary of Next-Generation Cisco Firewall discovery

The ServiceNow Discovery application includes a Next Generation Cisco Firewall pattern designed to identify Cisco firewall devices on your network.
This discovery leverages SNMP calls and supports horizontal discovery to populate detailed firewall information into the CMDB.
It requires the Madrid release or later on the ServiceNow AI Platform® and may need the latest Discovery and Service Mapping Patterns app from the ServiceNow Store for full functionality.

## Prerequisites and Setup

* Ensure SNMP access is enabled on your Cisco firewall devices.
* Configure SNMP credentials in your ServiceNow instance to allow communication.
* Add the Cisco device's SNMP system OID record to your instance for accurate classification.
* Update the classifier and class to include Cisco Firewall specifics.
* Download and install the Firewall extension classes app from the ServiceNow Store to add necessary CMDB classes.
* Install the Discovery and Service Mapping Patterns application and synchronize the discovery pattern with the appropriate MID Server.

## Data Captured by Discovery

The discovery process collects and stores comprehensive data about Cisco firewalls, including:

* **Device Identification:** Serial number, administrative name (FQDN), IP address, manufacturer, model ID, and description.
* **Firmware and OS Details:** Firmware version, hardware operating system, and its version.
* **Status Information:** Operational and hardware status indicators.
* **Network Interfaces:** IP addresses, netmasks, MAC addresses, and aliases for network adapters.
* **DNS Details:** Associated DNS names and IP addresses.

## Configuration Item (CI) Relationships

The pattern establishes key relationships among CIs to represent the firewall environment accurately:

* Cisco Firewall Devices own IP Addresses and Network Adapters.
* Firewall Devices use Router Interfaces.
* Network Adapters reference their owning Firewall Device and associated IP Addresses.
* Router Interfaces and Serial Numbers reference the Cisco Firewall Device.

## Benefits for ServiceNow Customers

By deploying this pattern, customers gain automated, consistent, and detailed discovery of Cisco firewall assets. This improves CMDB accuracy and supports better network and security management through up-to-date device data and clear dependency mappings.  
The ServiceNow
Discovery application uses the Next Generation Cisco Firewall pattern to find Cisco firewalls. Discovering some of these resources might 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 Cisco firewalls. Discovery uses the pattern to run horizontal discovery.

You can use this pattern on the ServiceNow AI Platform® using the Madrid release or later.

## Request apps on the Store {#cisco-fw-discovery__section_jj1_md3_slb}

Visit the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home) website to view all the available apps and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the [ServiceNow Store version history release notes](https://www.servicenow.com/docs/r/store-release-notes/sn-store-release-notes.html).{#cisco-fw-discovery__inline-send-to-store}

## Prerequisites {#cisco-fw-discovery__section_hx3_td3_slb}

* Ensure that your network firewall device has SNMP access.
* On the ServiceNow instance, configure SNMP credentials. For more information, see [SNMP credentials](https://www.servicenow.com/docs/access?context=c_SNMPCredentials&version=zurich&pubname=zurich-platform-security&ft:locale=en-US).
* Add the SNMP system OID record for the Cisco device to the ServiceNow instance. Update the following:
  * Classifier: Cisco Firewall
  * Class: Cisco Firewall Device
  {#cisco-fw-discovery__ul_utn_zd3_slb}
* Deploy the pattern as follows:
  1. Download and install [Firewall extension classes](https://www.servicenow.com/docs/access?context=cmdb-ci-class-models-fw&version=zurich&pubname=zurich-servicenow-platform&ft:locale=en-US) from the ServiceNow Store. The app adds the new CMDB classes required for network firewall discovery.
  2. Download and install the Discovery and Service Mapping Patterns application from the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home).
  3. Sync the pattern with the appropriate MID Server.
