New Features in FXOS 220.127.116.11
Warning: FXOS 18.104.22.168, which was briefly available on Cisco.com, is no longer supported. If you initially installed Firepower Threat Defense Version 6.0.1 on a Firepower 9300 or 4100 series device and have never reinstalled the Firepower software (you have only upgraded), upgrading to FXOS 22.214.171.124 disables the Firepower Threat Defense application. This may interrupt traffic on your network. If this happens to you, upgrade FXOS from Version 126.96.36.199 to Version 188.8.131.52 to restore Firepower Threat Defense functionality. For more information, see CSCvh64138 in the Cisco Bug Search Tool.
Cisco FXOS 184.108.40.206 introduces the following new features:
Support for ASA 9.9(1).
Support for Radware DefensePro 8.13.
Adds variable core allocation option for the installation of Radware DefensePro. When enabled, this feature allows you to optimize Radware DefensePro install performance.
The FXOS upgrade procedure no longer requires that you download the logical device CSP after upgrading the FXOS platform bundle. You can download any CSP onto your system before upgrading your FXOS to 2.3(1).
The Firepower 10G and 40G network modules now support hot swapping.
Improvements to the management of logical devices after creation:
After modifying the logical device using Firepower Chassis Manager to assign a new management IP address and bootstrap keys, Firepower Chassis Manager no longer automatically restarts the application.
If you make changes to a logical device that require a restart, Firepower Chassis Manager will notify you and allow you to restart after saving or delay restart until you initiate later.
You can now restart an application from the Firepower Chassis Manager Logical Devices page.
If you modify bootstrap information for a logical device using the FXOS CLI, you will not be notified when you must clear the management bootstrap and restart the application.
Improvements to the management of clusters:
Adds additional support for determining the time and the reason for application cluster state change; for example, when and why an application joins or leaves the cluster.
Adds additional support for identifying significant application state change, including online, offline, not-responding, install-failed, start-failed, stop-failed, update-failed, and unsupported.
Adds additional support for determining and reporting on the health of security modules.
For Firepower 9300/4100 series security appliances with an ASA security module, the flow off-loading feature has been improved to support 4 million bidirectional or 8 million unidirectional off-loaded flows.
Adds SNMP Support for network modules. Information about network modules are available by querying the ENTITY-MIB (OID 220.127.116.11.2.1.47), the IF-MIB (OID 18.104.22.168.2.1.31), and the CISCO-FIREPOWER-EQUIPMENT-MIB (OID 22.214.171.124.126.96.36.199.826.1.20).
Adds support for Smart Agent Strong Encryption in offline mode. This allows a Firepower 9300/4100 series security appliance to remain in its last known export compliance state, even if the connection to Cisco Smart Software Manager cannot be established.
Adds option to configure the minimum Transport Layer Security (TLS) version allowed when communicating with external devices.
The uplink port status of the management port on the Firepower 9300/4100 series security appliance is now synchronized with the management interface status in the applications running on it.
Fixes for various problems (see Resolved Bugs in FXOS 188.8.131.52).
You can download software images for FXOS and supported applications from one of the following URLs:
Firepower 9300 — https://software.cisco.com/download/type.html?mdfid=286287252
Firepower 4100 — https://software.cisco.com/download/navigator.html?mdfid=286305164
For information about the applications that are supported on a specific version or FXOS, see the Cisco FXOS Compatibility guide at this URL:
When you configure Radware DefensePro (vDP) in a service chain on a currently running Firepower Threat Defense application on a Firepower 4110 or 4120 device, the installation fails with a fault alarm. As a workaround, stop the Firepower Threat Defense application instance before installing the Radware DefensePro application. Note that this issue and workaround apply to all supported releases of Radware DefensePro service chaining with Firepower Threat Defense on Firepower 4110 and 4120 devices.
Firmware Upgrade—We recommend upgrading your Firepower 4100/9300 security appliance with the latest firmware. For information about how to install a firmware update and the fixes included in each update, see https://www.cisco.com/c/en/us/td/docs/security/firepower/fxos/firmware-upgrade/fxos-firmware-upgrade.html.
When upgrading a network or security module, certain faults are generated and then cleared automatically. These include a “hot swap not supported” fault or a “module removed when in online state” fault. If you have followed the appropriate procedures, as described in the Cisco Firepower 9300 Hardware Installation Guide ( http://www.cisco.com/go/firepower9300-install) or Cisco Firepower 4100 Series Hardware Installation Guide ( http://www.cisco.com/go/firepower4100-install), the fault(s) will be cleared automatically and no additional action is required.
Adapter Bootloader Upgrade
FXOS 2.3(1) contains additional testing to verify the security module adapters on your security appliance. After installing FXOS 184.108.40.206 or later, you might receive a critical fault similar to the following on your security appliance indicating that you should update the firmware for your security module adapter:
Critical F1715 2017-05-11T11:43:33.121 339561 Adapter 1 on Security Module 1 requires a critical firmware upgrade. Please see Adapter Bootloader Upgrade instructions in the FXOS Release Notes posted with this release.
If you receive the above message, use the following procedure to update the boot image for your adapter:
Connect to the FXOS CLI on your Firepower security appliance. For instructions, see the “Accessing the FXOS CLI” topic in the Cisco FXOS CLI Configuration Guide or the Cisco FXOS Firepower Chassis Manager Configuration Guide (see Related Documentation).
Enter the adapter mode for the adapter whose boot image you are updating:
fxos-chassis# scope adapter 1/security_module_number/adapter_number
Enter show image to view the available adapter images and to verify that fxos-m83-8p40-cruzboot.220.127.116.11.bin is available to be installed:
fxos-chassis /chassis/server/adapter # show image Name Type Version --------------------------------------------- -------------------- ------- fxos-m83-8p40-cruzboot.18.104.22.168.bin Adapter Boot 4.0(1.62) fxos-m83-8p40-vic.22.214.171.124.gbin Adapter 4.0(1.51)
Enter update boot-loader to update the adapter boot image to version 126.96.36.199:
fxos-chassis /chassis/server/adapter # update boot-loader 4.0(1.62) Warning: Please DO NOT reboot blade or chassis during upgrade, otherwise, it may cause adapter to become UNUSABLE! After upgrade has completed, blade will be power cycled automatically fxos-chassis /chassis/server/adapter* # commit-buffer
Enter show boot-update status to monitor the update status:
fxos-chassis /chassis/server/adapter # show boot-update status State: Updating fxos-chassis /chassis/server/adapter # show boot-update status State: Ready
Enter show version detail to verify that the update was successful:
Your show version detail output might differ from the following example. However, verify that Bootloader-Update-Status is “Ready” and that Bootloader-Vers is 4.0(1.62).
fxos-chassis /chassis/server/adapter # show version detail Adapter 1: Running-Vers: 5.2(1.2) Package-Vers: 2.2(2.17) Update-Status: Ready Activate-Status: Ready Bootloader-Update-Status: Ready Startup-Vers: 5.2(1.2) Backup-Vers: 5.0(1.2) Bootloader-Vers: 4.0(1.62)
You can access the Firepower Chassis Manager using the following browsers:
Mozilla Firefox—Version 42 and later
Google Chrome—Version 47 and later
Microsoft Internet Explorer—Version 11 and later
We tested FXOS 2.3(1) using Mozilla Firefox version 42, Google Chrome version 47, and Internet Explorer version 11. We anticipate that future versions of these browsers will also work. However, if you experience any browser-related issues, we suggest you revert to one of the tested versions.
For complete information on how to upgrade FXOS on your Firepower 4100/9300 device, see the Cisco Firepower 4100/9300 Upgrade Guide.
