Important Notes
•Increased SSH security; the SSH default username is no longer supported—Starting in 8.4(2), you can no longer connect to the ASA using SSH with the pix or asa username and the login password. To use SSH, you must configure AAA authentication using the aaa authentication ssh console LOCAL command (CLI) or Configuration > Device Management > Users/AAA > AAA Access > Authentication (ASDM); then define a local user by entering the username command (CLI) or choosing Configuration > Device Management > Users/AAA > User Accounts (ASDM). If you want to use a AAA server for authentication instead of the local database, we recommend also configuring local authentication as a backup method.
•Configuration Migration for Transparent Mode—In 8.4, all transparent mode interfaces now belong to a bridge group. When you upgrade to 8.4, the existing two interfaces are placed in bridge group 1, and the management IP address is assigned to the Bridge Group Virtual Interface (BVI). 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 8.3 and earlier, as an unsupported configuration, you could configure a management interface without an IP address, and you could access the interface using the device management address. In 8.4, the device management address is assigned to the BVI, and the management interface is no longer accessible using that IP address; the management interface requires its own IP address.
•You can upgrade from any previous release directly to 8.4. If you are upgrading from a pre-8.3 release, see the Cisco ASA 5500 Migration Guide for Version 8.3 and Later for important information about migrating your configuration to Version 8.3 and later.
Upgrading from some releases may have consequences for downgrading; be sure to back up your configuration file in case you want to downgrade. For example, If you are upgrading from a pre-8.2 release, see the 8.2 release notes for downgrade issues after you upgrade the Phone Proxy and MTA instance, or for downgrade issues if you upgrade the activation key with new 8.2 features.
•For pre-8.3 configurations, the migration of NAT exempt rules (the nat 0 access-list command) differs depending on the version to which you are upgrading. See the Cisco ASA 5500 Migration Guide for Version 8.3 and Later for more information.
•When upgrading to 8.4(2) from 8.3(1), 8.3(2), and 8.4(1), all identity NAT configurations will now include the no-proxy-arp and route-lookup keywords, to maintain existing functionality. The unidirectional keyword is removed.
•To run Version 8.3 and later in a production environment, you might need to upgrade the memory on the Cisco ASA 5505, 5510, 5520, or 5540. (For more information about upgrading, see the "Memory Information" section.) If you do not have enough memory, you receive the following message upon logging in:
***********************************************************************
** *** WARNING *** WARNING *** WARNING *** WARNING *** WARNING ***
** ----> Minimum Memory Requirements NOT Met! <----
** Upgrade part#: ASA5520-MEM-2GB=
** This ASA does not meet the minimum memory requirements needed to
** run this image. Please install additional memory (part number
** listed above) or downgrade to ASA version 8.2 or earlier.
** Continuing to run without a memory upgrade is unsupported, and
** critical system features will not function properly.
************************************************************************
•The Advanced Inspection and Prevention Security Services Card (AIP SSC) can take up to 20 minutes to initialize the first time it boots after a new image is applied. This initialization process must complete before configuration changes can be made to the sensor. Attempts to modify and save configuration changes before the initialization completes will result in an error.
•When you downgrade, you must manually restore the old configuration prior to downgrading.
•Connection Profile/Tunnel Group terminology in CLI vs. ASDM—The ASA tunnel groups define the initial connection parameters and attributes (such as AAA, client address assignment, and connection alias/group-url) for a remote access VPN session. In the CLI they are referred to as tunnel groups, whereas in ASDM they are referred to as Connection Profiles. A VPN policy is an aggregation of Connection Profile, Group Policy, and Dynamic Access Policy authorization attributes.
•Cosmetic startup message issue on the ASA 5585-X—Cisco manufacturing recently discovered a process error that resulted in loading a test build of BIOS firmware on many early shipments of the ASA 5585-X. On the affected units, more text than usual displays on the console during startup before reaching the "rommon>" prompt. Included in the extra output is the following message banner:
CISCO SYSTEMS Spyker Build, TEST build not for Customer Release
Embedded BIOS Version 2.0(7)2 19:59:57 01/04/11
While you may see this additional text, there is no functional impact to the ASA operation; you can ignore the additional text. The test build provides additional information that can be used by engineers to pinpoint hardware problems during the manufacturing process. Unfortunately, there is no field-upgradeable resolution to eliminate this message that does not require replacing the hardware.
Hardware with a serial number that falls within the following ranges could be impacted by this cosmetic issue. Note that not all serial numbers within these ranges are impacted.
–JMX1449xxxx - JMX1520xxxx
–JAF1450xxxx - JAF1516xxxx (for ASA-SSP-20-K8= only)
Hardware with the following Product IDs for the preceding serial numbers could be impacted by this cosmetic issue:
–ASA5585-S20-K8
–ASA5585-S20-K9
–ASA5585-S20P20-K8
–ASA5585-S20P20-K9
–ASA5585-S20P20XK9
–ASA5585-S20X-K9
–ASA-SSP-20-K8=
Limitations and Restrictions
•Currently in 8.4(2) and later, the PAT pool feature is not available as a fallback method for dynamic NAT or PAT. You can only configure the PAT pool as the primary method for dynamic PAT. For example, if you enter the following twice NAT command that configures a PAT pool (object2) for fallback when the addresses in object1 are used up, you see the following error message:
hostname(config)# nat (inside,outside) source dynamic any object1 pat-pool object2
interface round-robin
ERROR: Same mapped parameter cannot be used to do both NAT and PAT.
ERROR: NAT pool allocation failed.
You can alter this command to make it PAT-pool only by removing object1; the PAT pool is used as the primary method, instead of as a fallback method:
hostname(config)# nat (inside,outside) source dynamic any pat-pool object2 interface
round-robin
(CSCtq20634)
•No Payload Encryption for export—You can purchase the ASA 5585-X with No Payload Encryption. For export to some countries, payload encryption cannot be enabled on the Cisco ASA 5500 series. The ASA software senses a No Payload Encryption model, and disables the following features:
–Unified Communications
–VPN
You can still install the Strong Encryption (3DES/AES) license for use with management connections. For example, you can use ASDM HTTPS/SSL, SSHv2, Telnet and SNMPv3. You can also download the dynamic database for the Botnet Traffic Filer (which uses SSL).
•Stateful Failover with Phone Proxy—When using Stateful Failover with phone proxy, information is not passed to the standby unit; when the active unit goes down, the call fails, media stops flowing, and the call must be re-established.
•Clientless SSL VPN .NET limitation—Clientless SSL sessions might not properly support .NET framework applications. In some cases, you need to enable the application for use with Smart Tunnels; however, there is a chance it could still fail. For example, it might fail when an executable binary (.exe) is created using the .NET framework (CSCsv29942).
•The ASA does not support phone proxy with CIPC for remote access.
•The AIP SSC-5 does not support virtualization, unretiring default retired signatures, creating custom signatures, adding signatures, cloning signatures, or anomaly detection.
•ASA cannot fully support domain-based DFS. To support this, the ASA would need to join the Active Directory and query the Active Directory server for DFS referral. Instead the ASA sends the DFS referral to the DNS servers configured for the users. Because the AD server is the DNS server in most cases, the majority of customer configurations are covered.
•The Active Directory Agent, which is used for the Identity Firewall feature, does not support French. When IP-user mappings appear in French, the AD Agent drops the mapping because it parses the event based on the English language. The ASA cannot accept non-English characters in the console; therefore, users cannot configure an access rule with non-English usernames or user groups.
System Requirements
The sections that follow list the system requirements for operating an adaptive security appliance. This section includes the following topics:
•Minimum Active Directory PC Requirements for Identity Firewall in 8.4(2) and Later
•Memory Information
•ASDM, Module, and VPN Compatibility
Minimum Active Directory PC Requirements for Identity Firewall in 8.4(2) and Later
The Identity Firewall feature provides more granular access control based on user identities. You can configure access control and security policies based on usernames and groups rather than through source IP addresses. The ASA applies the security policies based on an association of IP addresses to Windows Active Directory login information and reports events based on the mapped usernames instead of network IP addresses.
The Identity Firewall integrates with Window Active Directory in conjunction with an external Active Directory (AD) Agent that provides the actual identity mapping. The ASA uses Windows Active Directory as the source to retrieve the current user identity information for specific IP addresses.
You can install the Active Directory Agent on a separate server or on the server where the Active Directory Domain Controller is installed.
Table 1 lists the minimum hardware requirements for the AD agent and the Active Directory Server Domain Controller.

DRAM, Flash Memory, and Failover
In a failover configuration, the two 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 chapters in the configuration guide.
Note If you use two units with different flash memory sizes, make sure that the unit with the smaller flash memory has enough space for the software images and configuration files.
ASDM, Module, and VPN Compatibility
Table 5 lists information about ASDM, module, and VPN compatibility with the ASA 5500 series.

Released: January 9, 2012
Table 6 lists the new features for ASA Version 8.4(3).
Table 6 New Features for ASA Version 8.4(3)
Feature
|
Description
|
NAT Features
|
Round robin PAT pool allocation uses the same IP address for existing hosts
|
When using a PAT pool with round robin allocation, if a host has an existing connection, then subsequent connections from that host will use the same PAT IP address if ports are available.
We did not modify any commands.
This feature is not available in 8.5(1).
|
Flat range of PAT ports for a PAT pool
|
If available, the real source port number is used for the mapped port. However, if the real port is not available, by default the mapped ports are chosen from the same range of ports as the real port number: 0 to 511, 512 to 1023, and 1024 to 65535. Therefore, ports below 1024 have only a small PAT pool.
If you have a lot of traffic that uses the lower port ranges, when using a PAT pool, you can now specify a flat range of ports to be used instead of the three unequal-sized tiers: either 1024 to 65535, or 1 to 65535.
We modified the following commands: nat dynamic [pat-pool mapped_object [flat [include-reserve]]] (object network configuration mode) and nat source dynamic [pat-pool mapped_object [flat [include-reserve]]] (global configuration mode).
This feature is not available in 8.5(1).
|
Extended PAT for a PAT pool
|
Each PAT IP address allows up to 65535 ports. If 65535 ports do not provide enough translations, you can now enable extended PAT for a PAT pool. Extended PAT uses 65535 ports per service, as opposed to per IP address, by including the destination address and port in the translation information.
We modified the following commands: nat dynamic [pat-pool mapped_object [extended]] (object network configuration mode) and nat source dynamic [pat-pool mapped_object [extended]] (global configuration mode).
This feature is not available in 8.5(1).
|
Configurable timeout for PAT xlate
|
When a PAT xlate times out (by default after 30 seconds), and the ASA reuses the port for a new translation, some upstream routers might reject the new connection because the previous connection might still be open on the upstream device. The PAT xlate timeout is now configurable, to a value between 30 seconds and 5 minutes.
We introduced the following command: timeout pat-xlate.
This feature is not available in 8.5(1).
|
Automatic NAT rules to translate a VPN peer's local IP address back to the peer's real IP address
|
In rare situations, you might want to use a VPN peer's real IP address on the inside network instead of an assigned local IP address. Normally with VPN, the peer is given an assigned local IP address to access the inside network. However, you might want to translate the local IP address back to the peer's real public IP address if, for example, your inside servers and network security is based on the peer's real IP address.
You can enable this feature on one interface per tunnel group. Object NAT rules are dynamically added and deleted when the VPN session is established or disconnected. You can view the rules using the show nat command.
Note Because of routing issues, we do not recommend using this feature unless you know you need this feature; contact Cisco TAC to confirm feature compatibility with your network. See the following limitations:
•Only supports Cisco IPsec and AnyConnect Client.
•Return traffic to the public IP addresses must be routed back to the ASA so the NAT policy and VPN policy can be applied.
•Does not support load-balancing (because of routing issues).
•Does not support roaming (public IP changing).
We introduced the following command: nat-assigned-to-public-ip interface (tunnel-group general-attributes configuration mode).
|
Remote Access Features
|
Clientless SSL VPN browser support
|
The ASA now supports clientless SSL VPN with Microsoft Internet Explorer 9 and Firefox 4.
|
Compression for DTLS and TLS
|
To improve throughput, Cisco now supports compression for DTLS and TLS on AnyConnect 3.0 or later. Each tunneling method configures compression separately, and the preferred configuration is to have both SSL and DTLS compression as LZS. This feature enhances migration from legacy VPN clients.
Note Using data compression on high speed remote access connections passing highly compressible data requires significant processing power on the ASA. With other activity and traffic on the ASA, the number of sessions that can be supported on the platform is reduced.
We introduced or modified the following commands: anyconnect dtls compression [lzs | none] and anyconnect ssl compression [deflate | lzs | none].
|
VPN Session Timeout Alerts
|
Allows you to create custom messages to alert users that their VPN session is about to end because of inactivity or a session timeout.
We introduced the following commands: vpn-session-timeout alert-interval, vpn-idle-timeout alert-interval.
|
AAA Features
|
Increased maximum LDAP values per attribute
|
The maximum number of values that the ASA can receive for a single attribute was increased from 1000 (the default) to 5000, with an allowed range of 500 to 5000. If a response message is received that exceeds the configured limit, the ASA rejects the authentication. If the ASA detects that a single attribute has more than 1000 values, then the ASA generates informational syslog 109036. For more than 5000 attributes, the ASA generates error level syslog 109037.
We introduced the following command: ldap-max-value-range number (Enter this command in aaa-server host configuration mode).
|
Support for sub-range of LDAP search results
|
When an LDAP search results in an attribute with a large number of values, depending on the server configuration, it might return a sub-range of the values and expect the ASA to initiate additional queries for the remaining value ranges. The ASA now makes multiple queries for the remaining ranges, and combines the responses into a complete array of attribute values.
|
Key vendor-specific attributes (VSAs) sent in RADIUS access request and accounting request packets from the ASA
|
Four New VSAs—Tunnel Group Name (146) and Client Type (150) are sent in RADIUS access request packets from the ASA. Session Type (151) and Session Subtype (152) are sent in RADIUS accounting request packets from the ASA. All four attributes are sent for all accounting request packet types: Start, Interim-Update, and Stop. The RADIUS server (for example, ACS and ISE) can then enforce authorization and policy attributes or use them for accounting and billing purposes.
|
Troubleshooting Features
|
Regular expression matching for the show asp table classifier and show asp table filter commands
|
You can now enter the show asp table classifier and show asp table filter commands with a regular expression to filter output.
We modified the following commands: show asp table classifier match regex, show asp table filter match regex.
|
New Features in Version 8.4(2.8)
Released: August 31, 2011
Table 7 lists the new features for ASA interim Version 8.4(2.8).
Note We recommend that you upgrade to a Cisco.com-posted ASA interim release only if you have a specific problem that it resolves. If you decide to run an interim release in a production environment, keep in mind that only targeted testing is performed on interim releases. Interim releases are fully supported by Cisco TAC and will usually remain on the download site only until the next maintenance release is available. If you choose to run an interim release, we strongly encourage you to upgrade to a fully-tested maintenance or feature release when it becomes available.
We will document interim release features at the time of the next maintenance or feature release. For a list of resolved caveats for each ASA interim release, see the interim release notes available on the Cisco.com software download site.

Description

Firewall Features
|
Identity Firewall
|
Typically, a firewall is not aware of the user identities and, therefore, cannot apply security policies based on identity.
The Identity Firewall in the ASA provides more granular access control based on users' identities. You can configure access rules and security policies based on usernames and user groups name rather than through source IP addresses. The ASA applies the security policies based on an association of IP addresses to Windows Active Directory login information and reports events based on the mapped usernames instead of network IP addresses.
The Identity Firewall integrates with Window Active Directory in conjunction with an external Active Directory (AD) Agent that provides the actual identity mapping. The ASA uses Windows Active Directory as the source to retrieve the current user identity information for specific IP addresses.
In an enterprise, some users log onto the network by using other authentication mechanisms, such as authenticating with a web portal (cut-through proxy) or by using a VPN. You can configure the Identity Firewall to allow these types of authentication in connection with identity-based access policies.
We introduced or modified the following commands: user-identity enable, user-identity default-domain, user-identity domain, user-identity logout-probe, user-identity inactive-user-timer, user-identity poll-import-user-group-timer, user-identity action netbios-response-fail, user-identity user-not-found, user-identity action ad-agent-down, user-identity action mac-address-mismatch, user-identity action domain-controller-down, user-identity ad-agent active-user-database, user-identity ad-agent hello-timer, user-identity ad-agent aaa-server, user-identity update import-user, user-identity static user, ad-agent-mode, dns domain-lookup, dns poll-timer, dns expire-entry-timer, object-group user, show user-identity, show dns, clear configure user-identity, clear dns, debug user-identity, test aaa-server ad-agent.
|
Identity NAT configurable proxy ARP and route lookup
|
In earlier releases for identity NAT, proxy ARP was disabled, and a route lookup was always used to determine the egress interface. You could not configure these settings. In 8.4(2) and later, the default behavior for identity NAT was changed to match the behavior of other static NAT configurations: proxy ARP is enabled, and the NAT configuration determines the egress interface (if specified) by default. You can leave these settings as is, or you can enable or disable them discretely. Note that you can now also disable proxy ARP for regular static NAT.
For pre-8.3 configurations, the migration of NAT exempt rules (the nat 0 access-list command) to 8.4(2) and later now includes the following keywords to disable proxy ARP and to use a route lookup: no-proxy-arp and route-lookup. The unidirectional keyword that was used for migrating to 8.3(2) and 8.4(1) is no longer used for migration. When upgrading to 8.4(2) from 8.3(1), 8.3(2), and 8.4(1), all identity NAT configurations will now include the no-proxy-arp and route-lookup keywords, to maintain existing functionality. The unidirectional keyword is removed.
We modified the following commands: nat static [no-proxy-arp] [route-lookup] (object network) and nat source static [no-proxy-arp] [route-lookup] (global).
|
PAT pool and round robin address assignment
|
You can now specify a pool of PAT addresses instead of a single address. You can also optionally enable round-robin assignment of PAT addresses instead of first using all ports on a PAT address before using the next address in the pool. These features help prevent a large number of connections from a single PAT address from appearing to be part of a DoS attack and makes configuration of large numbers of PAT addresses easy.
Note Currently in 8.4(2), the PAT pool feature is not available as a fallback method for dynamic NAT or PAT. You can only configure the PAT pool as the primary method for dynamic PAT (CSCtq20634).
We modifed the following commands: nat dynamic [pat-pool mapped_object [round-robin]] (object network) and nat source dynamic [pat-pool mapped_object [round-robin]] (global).
|
IPv6 Inspection
|
You can configure IPv6 inspection by configuring a service policy to selectively block IPv6 traffic based on the extension header. IPv6 packets are subjected to an early security check. The ASA always passes hop-by-hop and destination option types of extension headers while blocking router header and no next header.
You can enable default IPv6 inspection or customize IPv6 inspection. By defining a policy map for IPv6 inspection you can configure the ASA to selectively drop IPv6 packets based on following types of extension headers found anywhere in the IPv6 packet:
•Hop-by-Hop Options
•Routing (Type 0)
•Fragment
•Destination Options
•Authentication
•Encapsulating Security Payload
We modified the following commands: policy-map type inspect ipv6, verify-header, match header, match header routing-type, match header routing-address count gt, match header count gt.
|
Remote Access Features
|
Portal Access Rules
|
This enhancement allows customers to configure a global clientless SSL VPN access policy to permit or deny clientless SSL VPN sessions based on the data present in the HTTP header. If denied, an error code is returned to the clients. This denial is performed before user authentication and thus minimizes the use of processing resources.
We modified the following command: webvpn portal-access-rule.
Also available in Version 8.2(5).
|
Clientless support for Microsoft Outlook Web App 2010
|
The ASA 8.4(2) clientless SSL VPN core rewriter now supports Microsoft Outlook Web App 2010.
|
Secure Hash Algorithm SHA-2 Support for IPsec IKEv2 Integrity and PRF
|
This release supports the Secure Hash Algorithm SHA-2 for increased cryptographic hashing security for IPsec/IKEv2 AnyConnect Secure Mobility Client connections to the ASA. SHA-2 includes hash functions with digests of 256, 384, or 512 bits, to meet U.S. government requirements.
We modified the following commands: integrity, prf, show crypto ikev2 sa detail, show vpn-sessiondb detail remote.
|
Secure Hash Algorithm SHA-2 Support for Digital Signature over IPsec IKEv2
|
This release supports the use of SHA-2 compliant signature algorithms to authenticate IPsec IKEv2 VPN connections that use digital certificates, with the hash sizes SHA-256, SHA-384, and SHA-512.
SHA-2 digital signature for IPsec IKEv2 connections is supported with the AnyConnect Secure Mobility Client, Version 3.0.1 or later.
|
Split Tunnel DNS policy for AnyConnect
|
This release includes a new policy pushed down to the AnyConnect Secure Mobility Client for resolving DNS addresses over split tunnels. This policy applies to VPN connections using the SSL or IPsec/IKEv2 protocol and instructs the AnyConnect client to resolve all DNS addresses through the VPN tunnel. If DNS resolution fails, the address remains unresolved and the AnyConnect client does not try to resolve the address through public DNS servers.
By default, this feature is disabled. The client sends DNS queries over the tunnel according to the split tunnel policy: tunnel all networks, tunnel networks specified in a network list, or exclude networks specified in a network list.
We introduced the following command: split-tunnel-all-dns.
Also available in Version 8.2(5).
|
Mobile Posture
(formerly referred to as AnyConnect Identification Extensions for Mobile Device Detection)
|
You can now configure the ASA to permit or deny VPN connections to mobile devices, enable or disable mobile device access on a per group bases, and gather information about connected mobile devices based on a mobile device's posture data. The following mobile platforms support this capability: AnyConnect for iPhone/iPad/iPod Versions 2.5.x and AnyConnect for Android Version 2.4.x.
Licensing Requirements
Enforcing remote access controls and gathering posture data from mobile devices requires an AnyConnect Mobile license and either an AnyConnect Essentials or AnyConnect Premium license to be installed on the ASA. You receive the following functionality based on the license you install:
•AnyConnect Premium License Functionality
Enterprises that install the AnyConnect Premium license will be able to enforce DAP policies, on supported mobile devices, based on these DAP attributes and any other existing endpoint attributes. This includes allowing or denying remote access from a mobile device.
•AnyConnect Essentials License Functionality
Enterprises that install the AnyConnect Essentials license will be able to do the following:
–Enable or disable mobile device access on a per group basis and to configure that feature using ASDM.
–Display information about connected mobile devices via CLI or ASDM without having the ability to enforce DAP policies or deny or allow remote access to those mobile devices.
Also available in Version 8.2(5).
|
SSL SHA-2 digital signature
|
You can now use of SHA-2 compliant signature algorithms to authenticate SSL VPN connections that use digital certificates. Our support for SHA-2 includes all three hash sizes: SHA-256, SHA-384, and SHA-512. SHA-2 requires AnyConnect 2.5(1) or later (2.5(2) or later recommended). This release does not support SHA-2 for other uses or products.
Caution: To support failover of SHA-2 connections, the standby ASA must be running the same image.
We modified the following command: show crypto ca certificate (the Signature Algorithm field identifies the digest algorithm used when generating the signature).
Also available in Version 8.2(5).
|
SHA2 certificate signature support for Microsoft Windows 7 and Android-native VPN clients
|
ASA supports SHA2 certificate signature support for Microsoft Windows 7 and Android-native VPN clients when using the L2TP/IPsec protocol.
We did not modify any commands.
Also available in Version 8.2(5).
|
Enable/disable certificate mapping to override the group-url attribute
|
This feature changes the preference of a connection profile during the connection profile selection process. By default, if the ASA matches a certificate field value specified in a connection profile to the field value of the certificate used by the endpoint, the ASA assigns that profile to the VPN connection. This optional feature changes the preference to a connection profile that specifies the group URL requested by the endpoint. The new option lets administrators rely on the group URL preference used by many older ASA software releases.
We introduced the following command: tunnel-group-preference.
Also available in Version 8.2(5).
|
ASA 5585-X Features
|
Support for Dual SSPs for SSP-40 and SSP-60
|
For SSP-40 and SSP-60, you can use two SSPs of the same level in the same chassis. Mixed-level SSPs are not supported (for example, an SSP-40 with an SSP-60 is not supported). Each SSP acts as an independent device, with separate configurations and management. You can use the two SSPs as a failover pair if desired.
Note When using two SSPs in the chassis, VPN is not supported; note, however, that VPN has not been disabled.
We modified the following commands: show module, show inventory, show environment.
|
Support for the IPS SSP-10, -20, -40, and -60
|
We introduced support for the IPS SSP-10, -20, -40, and -60 for the ASA 5585-X. You can only install the IPS SSP with a matching-level SSP; for example, SSP-10 and IPS SSP-10.
Also available in Version 8.2(5).
|
CSC SSM Features
|
CSC SSM Support
|
For the CSC SSM, support for the following features has been added:
•HTTPS traffic redirection: URL filtering and WRS queries for incoming HTTPS connections.
•Configuring global approved whitelists for incoming and outgoing SMTP and POP3 e-mail.
•E-mail notification for product license renewals.
We did not modify any commands.
|
Monitoring Features
|
Smart Call-Home Anonymous Reporting
|
Customers can now help to improve the ASA platform by enabling Anonymous Reporting, which allows Cisco to securely receive minimal error and health information from the device.
We introduced the following commands: call-home reporting anonymous, call-home test reporting anonymous.
Also available in Version 8.2(5).
|
IF-MIB ifAlias OID support
|
The ASA now supports the ifAlias OID. When you browse the IF-MIB, the ifAlias OID will be set to the value that has been set for the interface description.
Also available in Version 8.2(5).
|
Interface Features
|
Support for Pause Frames for Flow Control on 1-Gigabit Ethernet Interface
|
You can now enable pause (XOFF) frames for flow control on 1-Gigabit Ethernet interfaces; support was previously added for 10-Gigabit Ethernet interfaces in 8.2(2).
We modified the following command: flowcontrol.
Also available in Version 8.2(5).
|
Management Features
|
Increased SSH security; the SSH default username is no longer supported
|
Starting in 8.4(2), you can no longer connect to the ASA using SSH with the pix or asa username and the login password. To use SSH, you must configure AAA authentication using the aaa authentication ssh console LOCAL command (CLI) or Configuration > Device Management > Users/AAA > AAA Access > Authentication (ASDM); then define a local user by entering the username command (CLI) or choosing Configuration > Device Management > Users/AAA > User Accounts (ASDM). If you want to use a AAA server for authentication instead of the local database, we recommend also configuring local authentication as a backup method.
|
Unified Communications Features
|
ASA-Tandberg Interoperability with H.323 Inspection
|
H.323 Inspection now supports uni-directional signaling for two-way video sessions. This enhancement allows H.323 Inspection of one-way video conferences supported by Tandberg video phones. Supporting uni-directional signaling allows Tandberg phones to switch video modes (close their side of an H.263 video session and reopen the session using H.264, the compression standard for high-definition video).
We did not modify any commands.
Also available in Version 8.2(5).
|
Routing Features
|
Timeout for connections using a backup static route
|
When multiple static routes exist to a network with different metrics, the ASA uses the one with the best metric at the time of connection creation. If a better route becomes available, then this timeout lets connections be closed so a connection can be reestablished to use the better route. The default is 0 (the connection never times out). To take advantage of this feature, change the timeout to a new value.
We modified the following command: timeout floating-conn.
Also available in Version 8.2(5).
|
New Features in Version 8.4(1.11)
Released: May 20, 2011
Table 9 lists the new features forASA interim Version 8.4(1.11).
Note We recommend that you upgrade to a Cisco.com-posted interim release only if you have a specific problem that it resolves. If you decide to run an interim release in a production environment, keep in mind that only targeted testing is performed on interim releases. Interim releases are fully supported by Cisco TAC and will remain on the download site only until the next maintenance release is available. If you choose to run an interim release, we strongly encourage you to upgrade to a fully-tested maintenance or feature release when it becomes available. We will document interim release features at the time of the next maintenance or feature release. For a list of resolved caveats for each interim release, see the interim release notes available on the Cisco.com software download site.

New Features in Version 8.4(1)
Released: January 31, 2011
Table 10 lists the new features for ASA Version 8.4(1).
Table 10 New Features for ASA Version 8.4(1)
Feature

Description
|
Hardware Features
|
Support for the ASA 5585-X
|
We introduced support for the ASA 5585-X with Security Services Processor (SSP)-10, -20, -40, and -60.
Note Support was previously added in 8.2(3) and 8.2(4); the ASA 5585-X is not supported in 8.3(x).
|
No Payload Encryption hardware for export
|
You can purchase the ASA 5585-X with No Payload Encryption. For export to some countries, payload encryption cannot be enabled on the Cisco ASA 5500 series. The ASA software senses a No Payload Encryption model, and disables the following features:
•Unified Communications
•VPN
You can still install the Strong Encryption (3DES/AES) license for use with management connections. For example, you can use ASDM HTTPS/SSL, SSHv2, Telnet and SNMPv3. You can also download the dynamic database for the Botnet Traffic Filer (which uses SSL).
|
Remote Access Features
|
L2TP/IPsec Support on Android Platforms
|
We now support VPN connections between Android mobile devices and ASA 5500 series devices, when using the L2TP/IPsec protocol and the native Android VPN client. Mobile devices must be using the Android 2.1, or later, operating system.
Also available in Version 8.2(5).
|
UTF-8 Character Support for AnyConnect Passwords
|
AnyConnect 3.0 used with ASA 8.4(1), supports UTF-8 characters in passwords sent using RADIUS/MSCHAP and LDAP protocols.
|
IPsec VPN Connections with IKEv2
|
Internet Key Exchange Version 2 (IKEv2) is the latest key exchange protocol used to establish and control Internet Protocol Security (IPsec) tunnels. The ASA now supports IPsec with IKEv2 for the AnyConnect Secure Mobility Client, Version 3.0(1), for all client operating systems.
On the ASA, you enable IPsec connections for users in the group policy. For the AnyConnect client, you specify the primary protocol (IPsec or SSL) for each ASA in the server list of the client profile.
IPsec remote access VPN using IKEv2 was added to the AnyConnect Essentials and AnyConnect Premium licenses.
Site-to-site sessions were added to the Other VPN license (formerly IPsec VPN). The Other VPN license is included in the Base license.
We modified the following commands: vpn-tunnel-protocol, crypto ikev2 policy, crypto ikev2 enable, crypto ipsec ikev2, crypto dynamic-map, crypto map.
|
SSL SHA-2 digital signature
|
This release supports the use of SHA-2 compliant signature algorithms to authenticate SSL VPN connections that use digital certificates. Our support for SHA-2 includes all three hash sizes: SHA-256, SHA-384, and SHA-512. SHA-2 requires AnyConnect 2.5.1 or later (2.5.2 or later recommended). This release does not support SHA-2 for other uses or products. This feature does not involve configuration changes.
Caution: To support failover of SHA-2 connections, the standby ASA must be running the same image. To support this feature, we added the Signature Algorithm field to the show crypto ca certificate command to identify the digest algorithm used when generating the signature.
|
SCEP Proxy
|
SCEP Proxy provides the AnyConnect Secure Mobility Client with support for automated third-party certificate enrollment. Use this feature to support AnyConnect with zero-touch, secure deployment of device certificates to authorize endpoint connections, enforce policies that prevent access by non-corporate assets, and track corporate assets. This feature requires an AnyConnect Premium license and will not work with an Essentials license.
We introduced or modified the following commands: crypto ikev2 enable, scep-enrollment enable, scep-forwarding-url, debug crypto ca scep-proxy, secondary-username-from-certificate, secondary-pre-fill-username.
|
Host Scan Package Support
|
This feature provides the necessary support for the ASA to install or upgrade a Host Scan package and enable or disable Host Scan. This package may either be a standalone Host Scan package or one that ASA extracts from an AnyConnect Next Generation package.
In previous releases of AnyConnect, an endpoint's posture was determined by Cisco Secure Desktop (CSD). Host Scan was one of many features bundled in CSD. Unbundling Host Scan from CSD gives AnyConnect administrators greater freedom to update and install Host Scan separately from the other features of CSD.
We introduced the following command: csd hostscan image path.
|
Kerberos Constrained Delegation (KCD)
|
This release implements the KCD protocol transition and constrained delegation extensions on the ASA. KCD provides Clientless SSL VPN (also known as WebVPN) users with SSO access to any web services protected by Kerberos. Examples of such services or applications include Outlook Web Access (OWA), Sharepoint, and Internet Information Server(IIS).
Implementing protocol transition allows the ASA to obtain Kerberos service tickets on behalf of remote access users without requiring them to authenticate to the KDC (through Kerberos). Instead, a user authenticates to ASA using any of the supported authentication mechanisms, including digital certificates and Smartcards, for Clientless SSL VPN (also known as WebVPN). When user authentication is complete, the ASA requests and obtains an impersonate ticket, which is a service ticket for ASA on behalf of the user. The ASA may then use the impersonate ticket to obtain other service tickets for the remote access user.
Constrained delegation provides a way for domain administrators to limit the network resources that a service trusted for delegation (for example, the ASA) can access. This task is accomplished by configuring the account under which the service is running to be trusted for delegation to a specific instance of a service running on a specific computer.
We modified the following commands: kcd-server, clear aaa, show aaa, test aaa-server authentication.
|
Clientless SSL VPN browser support
|
The ASA now supports clientless SSL VPN with Apple Safari 5.
|
Clientless VPN Auto Sign-on Enhancement
|
Smart tunnel now supports HTTP-based auto sign-on on Firefox as well as Internet Explorer. Similar to when Internet Explorer is used, the administrator decides to which hosts a Firefox browser will automatically send credentials. For some authentication methods, if may be necessary for the administrator to specify a realm string on the ASA to match that on the web application (in the Add Smart Tunnel Auto Sign-on Server window). You can now use bookmarks with macro substitutions for auto sign-on with Smart tunnel as well.
POST plug-in is now obsolete. The former POST plug-in was created so that administrators could specify a bookmark with sign-on macros and receive a kick-off page to load prior to posting the POST request. The post plug-in approach allows requests that required the presence of cookies, and other header items, fetched ahead of time to go through. The administrator can now specify pre-load pages when creating bookmarks to achieve the same functionality. Same as the POST plug-in, the administrator specifies the pre-load page URL and the URL to send the POST request to.
You can now replace the default preconfigured SSL VPN portal with your own portal. The administrators do this by specifying a URL as an External Portal. Unlike group-policy home page, External Portal supports POST requests with macro substitution (for auto sign-on) as well as pre-load pages.
We introduced or modified the following command: smart-tunnel auto-signon.
|
Expanded Smart Tunnel application support
|
Smart Tunnel adds support for the following applications:
•Microsoft Outlook Exchange Server 2010 (native support).
Users can now use Smart Tunnel to connect Microsoft Office Outlook to a Microsoft Exchange Server.
•Microsoft Sharepoint/Office 2010.
Users can now perform remote file editing using Microsoft Office 2010 Applications and Microsoft Sharepoint by using Smart Tunnel.
|
Interface Features
|
EtherChannel support (ASA 5510 and higher)
|
You can configure up to 48 802.3ad EtherChannels of eight active interfaces each.
Note You cannot use interfaces on the 4GE SSM, including the integrated 4GE SSM in slot 1 on the ASA 5550, as part of an EtherChannel.
We introduced the following commands: channel-group, lacp port-priority, interface port-channel, lacp max-bundle, port-channel min-bundle, port-channel load-balance, lacp system-priority, clear lacp counters, show lacp, show port-channel.
|
Bridge groups for transparent mode
|
If you do not want the overhead of security contexts, or want to maximize your use of security contexts, you can group interfaces together in a bridge group, and then configure multiple bridge groups, one for each network. Bridge group traffic is isolated from other bridge groups. You can configure up to 8 bridge groups in single mode or per context in multiple mode, with 4 interfaces maximum per bridge group.
Note Although you can configure multiple bridge groups on the ASA 5505, the restriction of 2 data interfaces in transparent mode on the ASA 5505 means you can only effectively use 1 bridge group.
We introduced the following commands: interface bvi, show bridge-group.
|
Scalability Features
|
Increased contexts for the ASA 5550, 5580, and 5585-X
|
For the ASA 5550 and ASA 5585-X with SSP-10, the maximum contexts was increased from 50 to 100. For the ASA 5580 and 5585-X with SSP-20 and higher, the maximum was increased from 50 to 250.
|
Increased VLANs for the ASA 5580 and 5585-X
|
For the ASA 5580 and 5585-X, the maximum VLANs was increased from 250 to 1024.
|
Additional platform support
|
Google Chrome has been added as a supported platform for ASA Version 8.4. Both 32-bit and 64-bit platforms are supported on Windows XP, Vista, and 7 and Mac OS X Version 6.0.
|
Increased connections for the ASA 5580 and 5585-X
|
We increased the firewall connection limits:
•ASA 5580-20—1,000,000 to 2,000,000.
•ASA 5580-40—2,000,000 to 4,000,000.
•ASA 5585-X with SSP-10: 750,000 to 1,000,000.
•ASA 5585-X with SSP-20: 1,000,000 to 2,000,000.
•ASA 5585-X with SSP-40: 2,000,000 to 4,000,000.
•ASA 5585-X with SSP-60: 2,000,000 to 10,000,000.
|
Increased AnyConnect VPN sessions for the ASA 5580
|
The AnyConnect VPN session limit was increased from 5,000 to 10,000.
|
Increased Other VPN sessions for the ASA 5580
|
The other VPN session limit was increased from 5,000 to 10,000.
|
High Availability Features
|
Stateful Failover with Dynamic Routing Protocols
|
Routes that are learned through dynamic routing protocols (such as OSPF and EIGRP) on the active unit are now maintained in a Routing Information Base (RIB) table on the standby unit. Upon a failover event, traffic on the secondary active unit now passes with minimal disruption because routes are known.
We modified the following commands: show failover, show route, show route failover.
|
Unified Communication Features
|
UC Protocol Inspection Enhancements
|
SIP Inspection and SCCP Inspection are enhanced to support new features in the Unified Communications Solutions; such as, SCCP v2.0 support, support for GETPORT messages in SCCP Inspection, SDP field support in INVITE messages with SIP Inspection, and QSIG tunneling over SIP. Additionally, the Cisco Intercompany Media Engine supports Cisco RT Lite phones and third-party video endpoints (such as, Tandberg).
We did not modify any commands.
|
Inspection Features
|
DCERPC Enhancement
|
DCERPC Inspection was enhanced to support inspection of RemoteCreateInstance RPC messages.
We did not modify an commands.
|
Troubleshooting and Monitoring Features
|
SNMP traps and MIBs
|
Supports the following additional keywords: connection-limit-reached, entity cpu-temperature, cpu threshold rising, entity fan-failure, entity power-supply, ikev2 stop | start, interface-threshold, memory-threshold, nat packet-discard, warmstart.
The entPhysicalTable reports entries for sensors, fans, power supplies, and related components.
Supports the following additional MIBs: ENTITY-SENSOR-MIB, CISCO-ENTITY-SENSOR-EXT-MIB, CISCO-ENTITY-FRU-CONTROL-MIB, CISCO-PROCESS-MIB, CISCO-ENHANCED-MEMPOOL-MIB, CISCO-L4L7MODULE-RESOURCE-LIMIT-MIB, NAT-MIB, EVENT-MIB, EXPRESSION-MIB
Supports the following additional traps: warmstart, cpmCPURisingThreshold, mteTriggerFired, cirResourceLimitReached, natPacketDiscard, ciscoEntSensorExtThresholdNotification.
We introduced or modified the following commands: snmp cpu threshold rising, snmp interface threshold, snmp-server enable traps.
|
TCP Ping Enhancement
|
TCP ping allows users whose ICMP echo requests are blocked to check connectivity over TCP. With the TCP ping enhancement you can specify a source IP address and a port and source interface to send pings to a hostname or an IPv4 address.
We modified the following command: ping tcp.
|
Show Top CPU Processes
|
You can now monitor the processes that run on the CPU to obtain information related to the percentage of the CPU used by any given process. You can also see information about the load on the CPU, broken down per process, at 5 minutes, 1 minute, and 5 seconds prior to the log time. Information is updated automatically every 5 seconds to provide real-time statistics, and a refresh button in the pane allows a manual data refresh at any time.
We introduced the following command: show process cpu-usage sorted.
|
General Features
|
Password Encryption Visibility
|
You can show password encryption in a security context.
We modified the following command: show password encryption.
|
Upgrading the Software
Note You can upgrade from any previous release (if available for your model) directly to the latest release. If you are upgrading from a pre-8.3 release to a post-8.3 release, see the Cisco ASA 5500 Migration Guide to Version 8.3 and Later for important information about migrating your configuration to Version 8.3 or later.
Upgrading from some releases may have consequences for downgrading; be sure to back up your configuration file in case you want to downgrade.
This section describes how to upgrade to the latest version and includes the following topics:
•Viewing Your Current Version
•Upgrading the Operating System and ASDM Images
Note For ASDM procedures, see the ASDM release notes.
Viewing Your Current Version
Use the show version command to verify the software version of your ASA.
Upgrading the Operating System and ASDM Images
This section describes how to install the ASDM and operating system (OS) images using TFTP. For FTP or HTTP, see the "Managing Software and Configurations" chapter in CLI configuration guide.
We recommend that you upgrade the ASDM image before the OS image. ASDM is backward compatible, so you can upgrade the OS using the new ASDM; however you cannot use an old ASDM image with a new OS.
For information about upgrading software in a failover pair, see the "Performing Zero Downtime Upgrades for Failover Pairs" chapter in the CLI configuration guide.
Detailed Steps
Step 1 If you have a Cisco.com login, you can obtain the OS and ASDM images from the following website:
http://www.cisco.com/go/asa-software
Step 2 Back up your configuration file. To print the configuration to the terminal, enter the following command:
hostname# show running-config
Copy the output from this command, then paste the configuration in to a text file.
Note If you are upgrading from a pre-8.3 version, then the running configuration is backed up automatically.
For other methods of backing up, see the "Managing Software and Configurations" chapter in the CLI configuration guide.
Step 3 Install the new images using TFTP. Enter this command separately for the OS image and the ASDM image:
hostname# copy tftp://server[/path]/filename {disk0:/ | disk1:/}[path/]filename
For example:
hostname# copy tftp://10.1.1.1/asa840-4-k8.bin disk0:/asa841-k8.bin
hostname# copy tftp://10.1.1.1/asdm-64099.bin disk0:/asdm-641.bin
If your ASA does not have enough memory to hold two images, overwrite the old image with the new one by specifying the same destination filename as the existing image.
Step 4 To change the OS boot image to the new image name, enter the following commands:
hostname(config)# clear configure boot
hostname(config)# boot system {disk0:/ | disk1:/}[path/]new_filename
For example:
hostname(config)# clear configure boot
hostname(config)# boot system disk0:/asa841-k8.bin
Step 5 To configure the ASDM image to the new image name, enter the following command:
hostname(config)# asdm image {disk0:/ | disk1:/}[path/]new_filename
Step 6 To save the configuration and reload, enter the following commands:
hostname(config)# write memory
Open Caveats
Table 11 contains open caveats in the latest maintenance release.
If you are running an older release, and you need to determine the open caveats for your release, then add the caveats in these sections to the resolved caveats from later releases. For example, if you are running Version 8.4(1), then you need to add the caveats in this section to the resolved caveats from 8.4(2) and higher to determine the complete list of open caveats.
If you are a registered Cisco.com user, view more information about each caveat using the Bug Toolkit at the following website:
