Therefore, we recommend using Version The version changed with this release to match the ASDM number. The access point includes an autonomous Cisco IOS image, which enables individual device management. The following table shows the supported software for the access point as well as the supported Cisco Wireless LAN Controller software if you convert to unified mode.

Due to CSCuv , we recommend that you upgrade to 9. You can ignore the message. If a network module is listed for multiple Firepower models, and the part number only differs in the model number FPR X K-NM- module , then that module is compatible with the other Firepower models. The ASA does not support the hardware bypass functionality of these modules, but you can use them as regular interfaces.

Clustering will work with both Cisco and non-Cisco switches from other major switching vendors with no known interoperability issues if they comply with the following requirements and recommendations. All third party switches must be compliant to the IEEE standard EtherChannel bundling must be completed within 45 seconds when connected to Firepower devices and 33 seconds when connected to ASA devices.

On the cluster control link, the switch must provide fully unimpeded unicast and broadcast connectivity at Layer 2 between all cluster members. On the cluster control link, the switch must not impose any limitations on IP addressing or the packet format above Layer 2 headers.

On the cluster control link, the switch interfaces must support jumbo frames and be configurable for an MTU above The switch should provide uniform traffic distribution over the EtherChannel's individual links. The switch should have an EtherChannel load-balancing algorithm that provides traffic symmetry.

The EtherChannel load balance hash algorithm should be configurable using the 5-tuple, 4-tuple, or 2-tuple to calculate the hash. For the Firepower cluster, intra-chassis clustering can operate with any switch because Firepower to-switch connections use standard interface types. With Version 8. For Version 9. You can check the size of internal flash and the amount of free flash memory on the ASA by doing the following:.

The amounts of total and available flash memory appear on the bottom left in the pane. The amounts of total and available flash memory appear on the bottom of the output.

See the following exceptions: ASA 8. Note The bold versions listed below are specially-qualified companion releases.

You can deploy the ASAv on the following hypervisors. Table The following table shows the switch hardware and software compatibility. Note that: ASA 9. Note If a network module is listed for multiple Firepower models, and the part number only differs in the model number FPR X K-NM- module , then that module is compatible with the other Firepower models.

Switch Recommendations The switch should provide uniform traffic distribution over the EtherChannel's individual links. Note For the Firepower cluster, intra-chassis clustering can operate with any switch because Firepower to-switch connections use standard interface types. Was this Document Helpful? ASA 9. To avoid loss of SSH connectivity, you can update your configuration before you upgrade. Sample original configuration for a username "admin":.

To use the ssh authentication command, before you upgrade, enter the following commands:. We recommend setting a password for the username as opposed to keeping the nopassword keyword, if present. The nopassword keyword means that any password can be entered, not that no password can be entered. Prior to 9. Now that the aaa command is required, it automatically also allows regular password authentication for a username if the password or nopassword keyword is present.

After you upgrade, the username command no longer requires the password or nopassword keyword; you can require that a user cannot enter a password. Therefore, to force public key authentication only, re-enter the username command:. After the reload, the startup configuration will be parsed correctly. For a cluster, follow the upgrade procedure in the FXOS release notes; no additional action is required. For the Firepower ASA security module, the feature mobile-sp command will automatically migrate to the feature carrier command.

The following CSD commands will migrate: csd enable migrates to hostscan enable ; csd hostscan image migrates to hostscan image. ASA X and X upgrade issue when upgrading to 9. Due to a manufacturing defect, an incorrect software memory limit might have been applied. If you upgrade to 9. If the memory shown is ,, or greater, then you can skip the rest of this procedure and upgrade as normal. We introduced or modified the following commands: ssl client-version, ssl server-version, ssl cipher, ssl trust-point, ssl dh-group.

We deprecated the following command: ssl encryption. We deprecated the following command: aaa-server protocol nt. The Auto Update Server certificate verification is now enabled by default; for new configurations, you must explicitly disable certificate verification. If you are upgrading from an earlier release, and you did not enable certificate verification, then certificate verification is not enabled, and you see the following warning:.

In order to verify this certificate please use the verify-certificate option. Upgrade impact for ASDM login when upgrading from a pre If you upgrade from a pre You must change the more command either before or after you upgrade to be at privilege level 5; only Admin level users can make this change. Note that ASDM version 7. Select more , and click Edit.

Change the Privilege Level to 5, and click OK. Click OK , and then Apply. This value does not include the Layer 2 header. ACLs not in use are removed. The any4 and any6 keywords are not available for all commands that use the any keyword. If you try to access the destination IP address on a different port not covered by a NAT rule, then the connection is blocked. This behavior is also true for Twice NAT. Moreover, traffic that does not match the source IP address of the Twice NAT rule will be dropped if it matches the destination IP address, regardless of the destination port.

Therefore, before you upgrade, you must add additional rules for all other traffic allowed to the destination IP address. If you want any other services to reach the server, such as FTP, then you must explicitly allow them:.

Or, to allow traffic to other ports of the server, you can add a general static NAT rule that will match all other ports:. If you want the outside hosts to reach another service on the inside server, add another NAT rule for the service, for example FTP:.

If you want other source addresses to reach the inside server on any other ports, you can add another NAT rule for that specific IP address or for any source IP address. Make sure the general rule is ordered after the specific rule. Configuration Migration for Transparent Mode—In 8. When you upgrade to 8. The functionality remains the same when using one bridge group. You can now take advantage of the bridge group feature to configure up to four interfaces per bridge group and to create up to eight bridge groups in single mode or per context.

Note In 8. When upgrading to 8. The unidirectional keyword is removed. See the following guide that describes the configuration migration process when you upgrade from a pre Zero Downtime Downgrades are not officially supported with clustering. Flow offload is disabled by default for ASA.

To perform a Failover or Clustering hitless upgrade when using flow offload, you need to follow the below upgrade paths to ensure that you are always running a compatible combination when upgrading to FXOS 2. For example, you are on FXOS 2. During this time, additional unit failures might result in lost sessions. Therefore, during a cluster upgrade, to avoid traffic loss, follow these steps.

On the chassis without the control unit, disable clustering on one module using the ASA console. If you are upgrading FXOS on the chassis as well as ASA, save the configuration so clustering will be disabled after the chassis reboots:. Repeat steps 1 through 6 on the second chassis, being sure to disable clustering on the data units first, and then finally the control unit. A new control unit will be chosen from the upgraded chassis.

After the cluster has stabilized, redistribute active sessions among all modules in the cluster using the ASA console on the control unit. Upgrade issue for 9. You should perform your upgrade to 9. Remove all secondary units from the cluster so the cluster consists only of the primary unit. Upgrade the remaining secondary units, and join them back to the cluster, one at a time. Zero Downtime Upgrade may not be supported when upgrading to the following releases with the fix for CSCvb If you set a custom cipher that only includes 3DES, then you may have a mismatch if the other side of the connection uses the default medium ciphers that no longer include 3DES.

This bug is present in 9. We suggest that you upgrade to a version that includes the fix for CSCuy 9. However, due to the nature of configuration replication, zero downtime upgrade is not available. See CSCuy for more information about different methods of upgrading. Firepower Threat Defense Version 6. If you deployed or re-deployed a 6.

Otherwise, the units will not be able to rejoin the cluster after the upgrade. If you already upgraded, change the site ID to 0 on each unit to resolve the issue. You can ignore this display; the status will show correctly when you upgrade all units. There are no special requirements for Zero Downtime Upgrades for failover with the following exceptions:. Upgrade issues with 8. You should instead upgrade to 8. To upgrade 9. Upgrade issue with GTP inspection—There could be some downtime during the upgrade, because the GTP data structures are not replicated to the new node.

Also, if you ever ran an earlier ASA version that had a vulnerable configuration, then regardless of the version you are currently running, you should verify that the portal customization was not compromised. If an attacker compromised a customization object in the past, then the compromised object stays persistent after you upgrade the ASA to a fixed version.

Upgrading the ASA prevents this vulnerability from being exploited further, but it will not modify any customization objects that were already compromised and are still present on the system. Before you upgrade, read the release notes for each FXOS version in your chosen upgrade path. Release notes contain important information about each FXOS release, including new features and changed functionality. Upgrading may require configuration changes that you must address.

Are there intermediate versions required? Back up your configurations. See the configuration guide for each operating system for backup methods. For example, ASDM 7. ASDM 7. Due to CSCuv , we recommend that you upgrade to 9. You can ignore the message. All devices support remote management with the FMC. The FMC must run the same or newer version as its managed devices.

This means:. You can manage older devices with a newer FMC , usually a few major versions back. However, we recommend you always update your entire deployment. New features and resolved issues often require the latest release on both the FMC and its managed devices. You cannot upgrade a device past the FMC. Even for maintenance third-digit releases, you must upgrade the FMC first. FMC Version. The bold versions listed below are specially-qualified companion releases.

You should use these software combinations whenever possible because Cisco performs enhanced testing for these combinations. FXOS 2. Other releases that are paired with 2. You can now run ASA 9. The following table lists the supported Radware DefensePro version for each Firepower security appliance and associated logical device.

For each operating system that you are upgrading, check the supported upgrade path. In some cases, you may have to install interim upgrades before you can upgrade to your final version. CLI: Use the show version command. This table provides upgrade paths for ASA. Some older versions require an intermediate upgrade before you can upgrade to a newer version.

Recommended versions are in bold. Be sure to check the upgrade guidelines for each release between your starting version and your ending version. You may need to change your configuration before upgrading in some cases, or else you could experience an outage. For the model, enter scope chassis 1 , and then show inventory. Find your current version combination in the left column. You can upgrade to any of the version combinations listed in the right column. This is a multi-step process: first upgrade FXOS, then upgrade the logical devices.

Note that this table lists only Cisco's specially qualified version combinations. For early versions of FXOS, you must upgrade to all intermediate versions between the current version and the target version. Once you reach FXOS 2. Downgrade of FXOS images is not officially supported. The only Cisco-supported method of downgrading an image version of FXOS is to perform a complete re-image of the device.

Find your current version in the left column. You can upgrade directly to any of the versions listed in the right column.
