Cisco ASA Compatibility
Last Updated:
December 6, 2016
This document lists the Cisco ASA software and hardware compatibility and requirements.
This section lists ASA and ASDM compatibility for current and legacy ASA models.
The following table lists ASA and ASDM compatibility for current models.
Note: ASDM 6.0 and later is backwards compatible, so we recommend that you upgrade to the latest version.

The ASA 5506W-X includes a Cisco Aironet 702i wireless access point integrated into the ASA. The access point includes an
autonomous Cisco IOS image, which enables individual device management. You can install the
lightweight image if you want to add the ASA 5506W-X to a Cisco Unified Wireless Network and use a wireless LAN controller. See the
chapter in the Cisco Wireless Control Configuration Guide for more information about using the lightweight image in unified mode.
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.

Many ASA models support service and I/O modules. This section lists the modules supported for current and legacy ASA models.
The following sections show the modules supported on each ASA model. To see the ASDM versions supported for each ASA version on your model, see .
For the IPS module, ASDM 7.1(6) and later are not compatible with IPS 7.3(2) and earlier. To manage an IPS module on an ASA, you must connect to the IPS IP address directly through your browser.
Except for ASA CX 9.3(2), ASA Software 9.1(5) is supported up to 9.1(5.21). With 9.1(5.21) and higher, CX 9.3(2) or higher are the only supported CX releases.

The ASA includes DRAM (also referred to as DIMM) and internal flash memory. On some models, you can optionally use an external flash memory as well. This section includes the following topics:
The following sections list the standard and recommended flash memory and DRAM.
See the following guidelines:
The ASA 5500-X models can run a software module such as the ASA IPS or ASA CX alongside the ASA firewall and *** functions. For these models, DRAM is evenly and statically distributed between the Firewall/*** functionality and the software module functionality, with 50% allocated to each. Memory for the software module is reserved even if you are not runni you cannot use that memory for firewall and *** functions. For other models with hardware modules, such as the ASA 5585-X, the modules include their own memory, so all of the ASA memory is used for firewall and ***.
For the ASA 5505 with Version 8.3 through 9.1, only the Unlimited Hosts license and the Security Plus license with failover enabled require 512 MB; other licenses can use 256 MB. For Version 9.2 and later, all ASA 5505 licenses require 512 MB.

See the following guidelines:
Note that the shipping DRAM increased after February 2010; the DRAM requirements for 8.3 and higher match the newer default shipping sizes. The newer default shipping DRAM is the current maximum DRAM you can install in your unit. See
to order an upgrade kit.
ASA 5520s and ASA 5540s manufactured before August 2011 have four DIMM sockets. ASA 5520s and ASA 5540s manufactured after this date have two DIMM sockets. All ASA 5550s have four DIMM sockets.
For the ASA 5510 through 5550, you might need to upgrade the internal flash memory to 512 MB or add external flash memory if you load multiple images of the AnyConnect client along with one or more images of the ASA software, ASDM, client/server plugins, or Cisco Secure Desktop. In particular, you might need to upgrade for multiple AnyConnect 3.0 and higher clients with optional modules.
The default internal flash memory for some models was 64 MB if you have one of these early units, we recommend upgrading your flash memory to at least the new shipping default.

(If you previously purchased the 512 MB upgrade kit for the ASA 5510 (ASA5510-MEM-512=), you must upgrade to the 1 GB memory upgrade kit to run Version 8.3.)

You can check the size of internal flash and the amount of free flash memory on the ASA by doing the following:
ASDM--Choose
Tools & File Management. The amounts of total and available flash memory appear on the bottom left in the pane.
CLI--In Privileged EXEC mode, enter the dir command. The amounts of total and available flash memory appear on the bottom of the output.

In a failover or cluster configuration, the units must have the same amount of DRAM. You do not have to have the same amount of flash memory. For more information, see the failover or clustering chapters in the configuration guide.
Note: If you use units with different flash memory sizes, make sure that the units with the smaller flash memory has enough space for the software images and configuration files.
