Create a FlexConfig object that configures the sysopt connection permit-vpn command. The new default for this command is no sysopt connection permit-vpn. The downside is that the VPN traffic will not be inspected, which means that intrusion and file protection, URL filtering, or other advanced features will not be applied to the traffic. Create access control rules to allow connections from the remote access VPN address pool. This method ensures that VPN traffic is inspected and advanced services can be applied to the connections.
The downside is that it opens the possibility for external users to spoof IP addresses and thus gain access to your internal network. In Version 6. If you disabled discovery in your current deployment, the upgrade process may enable it again. Disabling discovery if you don't need it for example, in an IPS-only deployment can improve performance.
Do not perform any kind of application, user, URL, or geolocation control. NEW Disable network and URL-based Security Intelligence by deleting all whitelists and blacklists from your access control policy's Security Intelligence configuration, including the default Global lists. If you upgrade while using vulnerability database VDB or later, an issue with the upgrade process prevents you from using CIP detection post-upgrade. Although we always recommend you update the vulnerability database VDB to the latest version after you upgrade, it is especially important in this case.
To check if you are affected by this issue, try to configure an access control rule with a CIP-based application condition. For network variables in an intrusion variable set, any IP addresses you exclude must be a subset of the IP addresses you include.
This table shows you examples of valid and invalid configurations. Before Version 6. Now, these configurations block deploy with the error: Variable set has invalid excluded values. If this happens, identify and edit the incorrectly configured variable set, then redeploy. Note that you may have to edit network objects and groups referenced by your variable set.
You can upgrade directly to Version 6. You do not need to be running any specific maintenance release or patch level. FXOS 2. Although the upgrade will succeed, you will experience significant performance issues and must contact Cisco TAC for a fix. You should instead upgrade to any intermediate release, then to Version 6. Or, you can upgrade directly from Version 6.
To upgrade a Firepower appliance, you must have enough free disk space or the upgrade fails. You must also have enough time to perform the upgrade. We provide reports of in-house time and disk space tests for reference purposes.
Values are from tests in a Firepower Management Center deployment. Raw upgrade times for remotely and locally managed devices are similar, given similar conditions. For major and maintenance releases, we test upgrades from all eligible previous major versions. For patches, we test upgrades from the base version. In most cases, we test on the lowest-end models in each series, and sometimes on multiple models in a series.
In a high availability or clustered configuration, devices upgrade one at a time to preserve continuity of operations, with each device operating in maintenance mode while it upgrades. Upgrading a device pair or entire cluster, therefore, takes longer than upgrading a standalone device. We test on appliances with minimal configurations and traffic load. For example, if you use a lot of access control rules and the upgrade needs to make a backend change to how those rules are stored, the upgrade can take longer.
Values represent only the time it takes for the Firepower software upgrade script. They do not include time for:. Space estimates are the largest reported for all Firepower software upgrades.
For releases after early , they are:. Values represent only the space needed to upload and run the Firepower software upgrade script. On some platforms, these locations may be on the same partition. After you select the appliance you want to check, under Disk Usage, expand the By Partition details.
Under Disk Usage, expand the By Partition details. To determine if this will affect you, log into the Firepower CLI on the device and use the show version command to display the Rules update version. When you upgrade the device software, operating system, or virtual hosting environment. We strongly recommend performing these tasks in a maintenance window or at a time when any interruption will have the least impact on your deployment.
Upgrade FXOS on each chassis independently, even if you have inter-chassis clustering or high availability pairs configured. How you perform the upgrade determines how your devices handle traffic during the FXOS upgrade. Upgrade FXOS on the active peer before the standby is finished upgrading. Best Practice: Upgrade one chassis at a time so at least one module is always online. Upgrade chassis at the same time, so all modules are down at some point. Hardware bypass disabled: Bypass: Disabled.
Devices operate in maintenance mode while they upgrade. Entering maintenance mode at the beginning of the upgrade causes a second interruption in traffic inspection. Interface configurations determine how a standalone device handles traffic both then and during the upgrade. Routed or switched including EtherChannel, redundant, subinterfaces.
Switched interfaces are also known as bridge group or transparent interfaces. Inline set, hardware bypass force-enabled: Bypass: Force 6. Passed without inspection until you either disable hardware bypass, or set it back to standby mode.
Inline set, hardware bypass standby mode: Bypass: Standby 6. Dropped during the upgrade, while the device is in maintenance mode. Then, passed without inspection while the device completes its post-upgrade reboot.
Inline set, hardware bypass disabled: Bypass: Disabled 6. You should not experience interruptions in traffic flow or inspection while upgrading high availability or clustered devices. For high availability pairs, the standby device upgrades first. The devices switch roles, then the new standby upgrades. For clusters, the data security module or modules upgrade first, then the control module. During the control security module upgrade, although traffic inspection and handling continues normally, the system stops logging events.
Events for traffic processed during the logging downtime appear with out-of-sync timestamps after the upgrade is completed. However, if the logging downtime is significant, the system may prune the oldest events before they can be logged.
Firepower Threat Defense with FDM : For high availability pairs, upgrade the standby, manually switch roles, then upgrade the new standby. Firepower Threat Defense with FMC : For standalone devices, interruptions to traffic flow and inspection during patch uninstall are the same as for upgrade. This is because you uninstall patches from devices individually, even those that you upgraded as a unit. You deploy configurations multiple times during the upgrade process. Snort typically restarts during the first deployment immediately after the upgrade.
It does not restart during other deployments unless, before deploying, you modify specific policy or device configurations. Interface configurations determine whether traffic drops or passes without inspection during the interruption. Inline set, Failsafe enabled or disabled 6. A few packets might drop if Failsafe is disabled and Snort is busy but not down. Inline set, Snort Fail Open: Down : disabled 6.
Inline set, Snort Fail Open: Down : enabled 6. Inline set, hardware bypass force-enabled: Bypass: Force Firepower series, 6. Inline set, hardware bypass standby mode: Bypass: Standby Firepower series, 6. Inline set, hardware bypass disabled: Bypass: Disabled Firepower series, 6. You should not experience interruptions in traffic flow or inspection while upgrading high availability devices.
Fail open sfr fail-open. Fail closed sfr fail-close. Additionally, restarting the Snort process interrupts traffic inspection. Your service policies determine whether traffic drops or passes without inspection during the interruption. Inquiry To Buy Find the Dealer.
