However, the ASA assigns the director role to a member at any site. Director localization enables additional director roles: a local director at the same site as the owner, and a global director that can be at any site. Keeping the owner and director at the same site improves performance. Also, if the original owner fails, the local director chooses a new connection owner at the same site.

The global director is used if a cluster member receives packets for a connection that is owned on a different site. We introduced or modified the following commands: director-localization, show asp table cluster chash, show conn, show conn detail. Interface link state monitoring polling for failover now configurable for faster detection.

By default, each ASA in a failover pair checks the link state of its interfaces every msec. You can now configure the polling interval, between msec and msec; for example, if you set the polltime to msec, the ASA can detect an interface failure and trigger failover faster.

We introduced the following command: failover polltime link-state. We introduced the following command: failover health-check bfd. Routes are added based on the negotiated selector information. The routes will be deleted after the IPsec SA's are deleted. We modified the following command: crypto map set reverse-route.

Using VTI does away with the need to configure static crypto map access lists and map them to interfaces. We introduced the following commands: crypto ipsec profile, interface tunnel, responder-only, set ikev1 transform-set, set pfs, set security-association lifetime, tunnel destination, tunnel mode ipsec, tunnel protection ipsec profile, tunnel source interface. SAML 2. With the ASA as a gateway between the user and services, authentication on IdP is handled with a restricted anonymous webvpn session, and all traffic between IdP and the user is translated.

We added the following command: saml idp. We modified the following commands: debug webvpn saml, show saml metadata. We modified the following commands: enrollment url, keypair, auto-update, crypto-ca-trustpoint, show crypto ca server certificates, show crypto key, show tech-support. The Aggregate Authentication protocol has been extended to define the protocol exchange for multiple-certificate authentication and utilize this for both session types.

The IKEv1 limit was left at A new method for smart-tunnel support in the Chrome browser on Mac and Windows devices was created. If you click on the smart tunnel enabled bookmark in Chrome without the extension already being installed, you are redirected to the Chrome Web Store to obtain the extension.

New Chrome installations will direct the user to the Chrome Web Store to download the extension. The extension downloads the binaries from ASA that are required to run smart tunnel. Your usual bookmark and application configuration while using smart tunnel is unchanged other than the process of installing the new extension.

All web interfaces will now display details of the current session, including the user name used to login, and user privileges which are currently assigned. This will help the user be aware of the current user session and will improve user security. All web applications will now grant access only after validating all security-related cookies. In each request, each cookie with an authentication token or a session ID will be verified before granting access to the user session.

Multiple session cookies in the same request will result in the connection being dropped. Cookies with failed validations will be treated as invalid and the event will be added to the audit log. The alert interval is the interval of time before max connection time is reached that a message will be displayed to the user warning them of termination. Valid time interval is minutes.

Default is 30 minutes. Previously supported for clientless and site-to-site VPN connections. The following command can now be used for AnyConnect connections: vpn-session-timeout alert-interval. We modified the following command: aaa-server host, test aaa-server. PBKDF2 hashing for all local username and enable passwords. Previously, passwords 32 characters and shorter used the MD5-based hashing method. Already existing passwords continue to use the MD5-based hash unless you enter a new password.

See the "Software and Configurations" chapter in the General Operations Configuration Guide for downgrading guidelines. We modified the following commands: enable password, username. Only the active unit requests the license entitlements. Previously, both units requested license entitlements. Supported with FXOS 2. The traceroute command was modified to accept an IPv6 address. Support for the packet tracer for bridge group member interfaces.

You can now use the packet tracer for bridge group member interfaces. We added two new options to the packet-tracer command; vlan-id and dmac. We modified the following commands: logging host, show running config, show logging. Version 9. You can add and remove Virtio virtual interfaces on the ASAv while the system is active.

When you add a new interface to the ASAv, the virtual machine detects and provisions the interface. When you remove an existing interface, the virtual machine releases any resource associated with the interface. You can optionally configure this interface to be management-only, but it is not configured by default. We modified the following command: management-only. See the rows in this table for the following features that were added for this certification:. We added the following command: tcp-inspection.

You can now inspect M3UA traffic and also apply actions based on point code, service indicator, and message class and type. Inspection opens pinholes required for return traffic. We added or modified the following commands: inspect stun , show conn detail , show service-policy inspect stun. You can now configure Cisco Cloud Web Security to check the health of the Cloud Web Security application when determining if the server is healthy.

By checking application health, the system can fail over to the backup server when the primary server responds to the TCP three-way handshake but cannot process requests. This ensures a more reliable system. We added the following commands: health-check application url , health-check application timeout.

You can now configure how long the system should maintain a connection when the route used by the connection no longer exists or is inactive. If the route does not become active within this holddown period, the connection is freed.

You can reduce the holddown timer to make route convergence happen more quickly. However, the 15 second default is appropriate for most networks to prevent route flapping. We added the following command: timeout conn-holddown. In addition, the default handling of the MSS, timestamp, window-size, and selective-ack options has changed. Previously, these options were allowed, even if there were more than one option of a given type in the header. Now, packets are dropped by default if they contain more than one option of a given type.

For example, previously a packet with 2 timestamp options would be allowed, now it will be dropped. For the MD5 option, the previous default was to clear the option, whereas the default now is to allow it. You can also drop packets that contain the MD5 option. The default for all other TCP options remains the same: they are cleared. We modified the following command: tcp-options. You can now offload multicast connections to be switched directly in the NIC on transparent mode Firepower and series devices.

Multicast offload is available for bridge groups that contain two and only two interfaces. You can set the maximum number of ARP packets allowed per second. The default value depends on your ASA model. You can customize this value to prevent an ARP storm attack. We added the following commands: arp rate-limit, show arp rate-limit.

Ethertype rule support for the IEEE Because of this addition, the bpdu keyword no longer matches the intended traffic. Rewrite bpdu rules for dsap 0x We modified the following commands: access-list ethertype. Remote access VPN in multiple context mode now supports flash virtualization. Each context can have a private storage space and a shared storage place based on the total flash that is available:.

Private storage—Store files associated only with that user and specific to the content that you want for that user. We introduced the following commands: limit-resource storage, storage-url. AnyConnect client profiles are supported in multiple context mode.

Stateful failover is now supported for AnyConnect connections in multiple context mode. Localization is supported globally. There is only one set of localization files that are shared across different contexts. It can be used in place of tunnel default mode. Tunnel mode encapsulates the entire IP packet. Transport mode encapsulates only the upper-layer protocols of an IP packet.

Transport mode requires that both the source and destination hosts support IPSec, and can only be used when the destination peer of the tunnel is the final destination of the IP packet. We modified the following command: crypto map set ikev2 mode.

By default, per-packet adjacency lookups are done for outer ESP packets; lookups are not done for packets sent through the IPsec tunnel. To prevent this, use the new option to enable per-packet routing lookups for the IPsec inner packets. We added the following command: crypto ipsec inner-routing-lookup. If not, the connection fails. For an ASDM user who authenticates with a certificate, you can now require the certificate to match a certificate map.

We modified the following command: http authentication-certificate match. If the presented identity cannot be matched against the configured reference identity, the connection is not established. We added or modified the following commands: crypto ca reference-identity, logging host, call home profile destination address.

The ASA crypto system has been updated to comply with new key zeroization requirements. Keys must be overwritten with all zeros and then the data must be read to verify that the write was successful. To disallow users from using a password instead of the private key, you can now create a username without any password defined.

We modified the following commands: ssh authentication, username. You can set the maximum MTU to bytes on the Firepower and ; formerly, the maximum was bytes. Support was added for configuring BFD templates, interfaces, and maps.

We added or modified the following commands: authentication, bfd echo, bfd interval, bfd map, bfd slow-timers, bfd template, bfd-template, clear bfd counters, echo, debug bfd, neighbor fall-over bfd, show bfd drops, show bfd map, show bfd neighbors, show bfd summary. We added or modified the following commands: clear ipv6 dhcp statistics, domain-name, dns-server, import, ipv6 address autoconfig, ipv6 address dhcp, ipv6 dhcp client pd, ipv6 dhcp client pd hint, ipv6 dhcp pool, ipv6 dhcp server, network, nis address, nis domain-name, nisp address, nisp domain-name, show bgp ipv6 unicast, show ipv6 dhcp, show ipv6 general-prefix, sip address, sip domain-name, sntp address.

Previously, with large dACLs, the sync time could take hours during which time the standby unit is busy syncing instead of providing high availability backup. For highly secure environments where communication with the Cisco Smart Software Manager is not allowed, you can request a permanent license for the ASAv.

This feature is not supported for Microsoft Azure. Not all accounts are approved for permanent license reservation. Make sure you have approval from Cisco for this feature before you attempt to configure it. We introduced the following commands: license smart reservation, license smart reservation cancel, license smart reservation install, license smart reservation request universal, license smart reservation return. If your devices cannot access the internet for security reasons, you can optionally install a local Smart Software Manager satellite server as a virtual machine VM.

Due to an update to the Smart Agent to 1. For highly secure environments where communication with the Cisco Smart Software Manager is not allowed, you can request a permanent license for the ASA on the Firepower and Firepower All available license entitlements are included in the permanent license, including the Standard Tier, Strong Encryption if qualified , Security Contexts, and Carrier licenses.

Requires FXOS 2. The smart agent was upgraded from Version 1. If you downgrade from Version 9. We introduced the following commands: show license status, show license summary, show license udi, show license usage. We modified the following commands: show license all, show tech-support license. We deprecated the following commands: show license cert, show license entitlement, show license pool, show license registration.

When you create a packet capture of type asp-drop, you can now also specify an ACL or match option to limit the scope of the capture. You can create a core dump of any process running on the ASA. We modified the following commands: copy system:text, verify system:text, crashinfo force dump process. Two counters were added that allow Netflow users to see the number of Layer 4 packets being sent in both directions on a connection.

You can use these counters to determine average packet rates and sizes and to better predict traffic types, anomalies, and events. If a user does not specify the native engineID, the show running config output will show two engineIDs per user. The ASAv 9. They are available in 9. The card appears as disk3 in the ASA file system. Note that plug and play support requires hardware version 2. Use the show module command to check your hardware version.

If one power supply fails, the ASA issues an alarm. By default, the ASA expects a single power supply and won't issue an alarm as long as it includes one working power supply. We introduced the following command: power-supply dual. Diameter inspection improvements. We introduced or modified the following commands: client clear-text , inspect diameter , strict-diameter.

SCTP stateful inspection in cluster mode. SCTP stateful inspection now works in cluster mode. You can also configure SCTP stateful inspection bypass in cluster mode. You can now configure an H. We introduced the following command: early-message. We added an option to the Call Attributes tab in the H.

Remote Access Features. We introduced the following commands: crypto ikev2 fragmentation , show running-config crypto ikev2 , show crypto ikev2 sa detail. The crypto engine accelerator-bias command is now supported on the ASA security module on the Firepower and Firepower series. We modified the following command: crypto engine accelerator-bias. Users can select cipher modes when doing SSH encryption management and can configure HMAC and encryption for varying key exchange algorithms.

You might want to change the ciphers to be more or less strict, depending on your application. Note that the performance of secure copy depends partly on the encryption cipher used. By default, the ASA negotiates one of the following algorithms in order: 3des-cbc aescbc aescbc aescbc aesctr aesctr aesctr. If the first algorithm proposed 3des-cbc is chosen, then the performance is much slower than a more efficient algorithm such as aescbc.

To change the proposed ciphers, use ssh cipher encryption custom aescbc , for example. We introduced the following commands: ssh cipher encryption, ssh cipher integrity. Also available in 9. We added functionality to the following command: http redirect. Support was added for routing data, performing authentication, and redistributing and monitoring routing information using the IS-IS routing protocol.

We introduced the following screens:. For inter-site clustering in routed mode with Spanned EtherChannels, you can now configure site-specific IP addresess in addition to site-specific MAC addresses. We modified the following commands: mac-address, show interface. Longer password support for local username and enable passwords up to characters. You can now create local username and enable passwords up to characters the former limit was Shorter passwords continue to use the MD5-based hashing method.

We modified the following commands: enable, username. This is a table of memory pool monitoring entries for all physical entities on a managed system. Platform Features. This provides improved performance for large data flows in data centers. We added or modified the following commands: clear flow-offload , flow-offload enable , set-connection advanced-options flow-offload , show conn detail , show flow-offload.

High Availability Features. Inter-chassis clustering for 6 modules, and inter-site clustering for the ASA on the Firepower With FXOS 1. You can include up to 6 modules in up to 6 chassis. For regular Cisco Smart Software Manager users, the Strong Encryption license is automatically enabled for qualified customers when you apply the registration token on the Firepower We removed the following command for non-satellite configurations: feature strong-encryption. It is low-power, fan-less, with Gigabit Ethernet and a dedicated management port.

This model comes with the ASA Firepower module pre-installed. Special features for this model include a customized transparent mode default configuration, as well as a hardware bypass function to allow traffic to continue flowing through the appliance when there is a loss of power. We introduced the following command: hardware-bypass, hardware-bypass manual, hardware-bypass boot-delay.

We introduced the following command: match [ not ] uuid. We modified the following command: class-map type inspect. You can now inspect Diameter traffic. Diameter inspection requires the Carrier license. We introduced or modified the following commands: class-map type inspect diameter , diameter , inspect diameter , match application-id , match avp , match command-code , policy-map type inspect diameter , show conn detail , show diameter , show service-policy inspect diameter , unsupported.

SCTP inspection requires the Carrier license. We introduced the following commands: access-list extended , clear conn protocol sctp , inspect sctp , match ppid , nat static object , policy-map type inspect sctp , service-object , service , set connection advanced-options sctp-state-bypass , show conn protocol sctp , show local-host connection sctp , show service-policy inspect sctp , timeout sctp.

The ASA X now supports 2-unit clusters. Clustering for 2 units is enabled by default in the base license. By default, all levels of clustering events are included in the trace buffer, including many low level events. To limit the trace to higher level events, you can set the minimum trace level for the cluster. You can now configure one or more secondary VLANs for a subinterface.

We introduced or modified the following commands: vlan secondary, show vlan mapping. Routing Features. We introduced the following commands: clear pim group-map, debug pim bsr, pim bsr-border, pim bsr-candidate, show pim bsr-router, show pim group-map rp-timers. The AnyConnect Apex license is required for multiple context mode; you cannot use the default or legacy license.

We introduced the following commands: limit-resource vpn anyconnect, limit-resource vpn burst anyconnect. You can debug logs by filtering, based on the filter condition sets, and can then better analyze them. If you want to enable the cache, you must manually enable it.

Smart licensing uses the Smart Call Home infrastructure. When the ASA first configures Smart Call Home anonymous reporting in the background, it automatically creates a trustpoint containing the certificate of the CA that issued the Smart Call Home server certificate.

The ASA now supports validation of the certificate if the issuing hierarchy of the server certificate changes; you can enable the automatic update of the trustpool bundle at periodic intervals. For the ASA on the Firepower , the feature mobile-sp command will automatically migrate to the feature carrier command.

We introduced or modified the following commands: feature carrier, show activation-key, show license, show tech-support, show version. We modified the following commands: snmp-server user, no snmp-server user. Includes dir all-filesystems output—This output can be helpful in the following cases:. Removes the show kernel cgroup-controller detail output—This command output will remain in the output of show tech-support detail.

Formerly, when you enabled logging debug-trace to redirect debugs to a syslog server, if the SSH connection were disconnected due to network connectivity or timeout , then the debugs were removed. Now, debugs persist for as long as the logging command is in effect. The 6. The NVM collects the endpoint telemetry and logs both the flow data and the file reputation in the syslog and also exports the flow records to a collector a third-party vendor , which performs the file analysis and provides a UI interface.

Formerly, it required 2 GB. For already-deployed ASAv5s, you should reduce the allocated memory to 1 GB or you will see an error that you are using more memory than is licensed. We modified the following commands: clear service-policy inspect gtp statistics, clear service-policy inspect gtp pdpmcb, clear service-policy inspect gtp request, match message id, show service-policy inspect gtp pdpmcb, show service-policy inspect gtp request, show service-policy inspect gtp statistics, timeout endpoint.

Cluster replication delay for TCP connections. We introduced the following command: cluster replication delay. Disable health monitoring of a hardware module in ASA clustering.

If you do not want a hardware module failure to trigger failover, you can disable module monitoring. We modified the following command: health-check monitor-interface service-module. This feature lets you use all other interfaces on the device as data interfaces. We modified the following commands: failover lan interface, failover link. IPv6 addresses are now supported for Policy Based Routing.

We introduced the following commands: set ipv6 next-hop, set default ipv6-next hop, set ipv6 dscp. Separate routing table for management-only interfaces. To segregate and isolate management traffic from data traffic, the ASA now supports a separate routing table for management-only interfaces. We introduced or modified the following commands: backup, clear ipv6 route management-only, clear route management-only, configure http, configure net, copy, enrollment source, name-server, restore, show asp table route-management-only, show ipv6 route management-only show route management-only.

This feature allows greater flexibility in choosing a multicast group while also protecting against different attacks; hosts only receive traffic from explicitly-requested sources. Added support and a predefined application template for this new SharePoint version. The overall banner length, which is displayed during post-login on the VPN remote client portal, has increased from to We modified the following command: banner group-policy.

Note that only one ASA interface can act as the Easy VPN port; to connect multiple devices to that port, you need to place a Layer 2 switch on the port, and then connect your devices to the switch. We introduced the following commands: vpnclient enable, vpnclient server, vpnclient mode, vpnclient username, vpnclient ipsec-over-tcp, vpnclient management, vpnclient vpngroup, vpnclient trustpoint, vpnclient nem-st-autoconnect, vpnclient mac-exempt.

You can now show invalid usernames in syslog messages for unsuccessful login attempts. The default setting is to hide usernames when the username is invalid or if the validity is unknown. You might want to show invalid usernames to help with troubleshooting login issues. We introduced the following command: no logging hide username. This feature is also available in 9. Monitoring Features. We introduced the following commands: hardware-bypass, hardware-bypass manual, hardware-bypass boot-delay, show hardware-bypass.
