We modified the following command: show tech support. This is a table of memory pool monitoring entries for all physical entities on a managed system. This value does not include the Layer 2 header. We modified the following command: mtu. Table 3 lists the new features for ASA Version 9. We introduced the following commands: ssh pubkey-chain , server ssh pubkey-chain , key-string , key-hash , ssh stricthostkeycheck.
We modified the following command: copy scp. Administrators who have sufficient authorization privileges may enter privileged EXEC mode by entering their authentication credentials once.
The auto-enable option was added to the aaa authorization exec command. We modified the following command: aaa authorization exec.
Transactional Commit Model on rule engine for access groups. When enabled, a rule update is applied after the rule compilation is completed; without affecting the rule matching performance. We introduced the following comands: asp rule-engine transactional-commit , show running-config asp rule-engine transactional-commit , clear configure asp rule-engine transactional-commit.
You can now add up to hosts. The number of supported active polling destinations is You can specify a network object to indicate the individual hosts that you want to add as a host group.
You can associate more than one user with one host. We introduced or modified the following commands: snmp-server host-group , snmp-server user-list , show running-config snmp-server , clear configure snmp-server.
This data is equivalent to the show xlate count command. Also available in 8. For example, this could result in streaming video playing poorly or cease streaming completely. The reason for this was the relatively small size of the flow control queue.
We increased the DTLS flow-control queue size and offset this by reducing the admin crypto queue size. For TLS sessions, the priority of the crypto command was increased to high to compensated for this change. This will prevent media streams from closing and ensure that the number of dropped packets is comparable with other connection methods. We introduced URL normalization. URL normalization is an additional security feature that includes path normalization, case normalization and scheme normalization.
URLs specified in an ACE and portal address bar are normalized before comparison; for making decisions on webvpn traffic filtering. You must configure the following to meet the requirement:. Table 4 lists the new features for ASA Version 9. The ASA will now proxy this request to the backend and provide a relay after the handshake is complete. Gateway mode is not currently supported. For a single traffic type, or when GRE is not supported by the client or the headend, we use straight IPsec.
Output of the show ipsec sa and show vpn-sessiondb detail anyconnect commands has been updated to reflect the assigned IPv6 address, and to indicate the GRE Transport Mode security association when doing IKEv2 dual traffic. If the depracated ipv6-vpn-filter command is used to configure IPv6 ACLs the connection will be terminated. Mobile Devices running Citrix Server Mobile have additional connection options.
Allowing mobile users to select different tunnel-groups allows the administrator to use different authentication methods. We introduced the application-type command to configure the default tunnel group for VDI connections when a Citrix Receiver user does not choose a tunnel-group. A none action was added to the vdi command to disable VDI configuration for a particular group policy or user.
Exclude ACLs were previously ignored. Clustering for 2 units is enabled by default in the base license; for the ASA X, you need the Security Plus license. If you configure the cluster control link as an EtherChannel recommended , and it is connected to a VSS or vPC pair, you can now increase stability with health check monitoring. We modified the following command: health-check [ vss-enabled ]. Support for cluster members at different geographical locations inter-site ; Individual Interface mode only.
You can now place cluster members at different geographical locations when using individual interface mode. See the configuration guide for inter-site guidelines. Prior to this release, the client did not rebind to an alternate server, when the DHCP lease fails to renew. We introduced the following commands: show ip address dhcp lease proxy, show ip address dhcp lease summary, and show ip address dhcp lease server.
Application Kernel Layer 4 to 7 AK47 framework-related information is now available in crashinfo dumps. A new option, ak47 , has been added to the debug menu command to help in debugging AK47 framework issues.
The framework-related information in the crashinfo dump includes the following:. Table 5 lists the new features for ASA Version 9. In multiple context mode, configure the packet capture per context. Note that all control traffic in multiple context mode goes only to the system execution space. Because only control traffic cannot be filtered using an access list or match, these options are not available in the system execution space.
You can now view the top bin sizes allocated and the top 10 PCs for each allocated bin size. Previously, you had to enter multiple commands to see this information the show memory detail command and the show memory binsize command ; the new command provides for quicker analysis of memory issues. We introduced the following command: show memory top-usage. A Smart Call Home clustering message is sent for only the following three events:. Each message that is sent includes the following information:.
We modified the following commands: show call-home, show running-config call-home. The password in the user-storage value command is now encrypted when you enter show running-config. We modified the following command: user-storage value. Table 6 lists the new features for ASA Version 9. Note : Features added in 8. Instead of using the proprietary encryption for the failover key the failover key command , you can now use an IPsec LAN-to-LAN tunnel for failover and state link encryption.
We introduced or modified the following commands: failover ipsec pre-shared-key , show vpn-sessiondb. See the following limitations:. We modified the following command: ssl encryption. Support for administrator password policy when using the local database. When you configure authentication for CLI or ASDM access using the local database, you can configure a password policy that requires a user to change their password after a specified amount of time and also requires password standards such as a minimum length and the minimum number of changed characters.
We introduced the following commands: change-password, password-policy lifetime , password-policy minimum changes , password-policy minimum-length , password-policy minimum-lowercase , password-policy minimum-uppercase , password-policy minimum-numeric , password-policy minimum-special , password-policy authenticate enable , clear configure password-policy , show running-config password-policy.
You can specify a public key file PKF formatted key or a Base64 key. The PKF key can be up to bits. We introduced the following commands: ssh authentication. We introduced the following command: show ssh sessions detail. Formerly, only Group 1 was supported. We introduced the following command: ssh key-exchange. Support for a maximum number of management sessions. We introduced the following commands: quota management-session , show running-config quota management-session , show quota management-session.
To improve security for management access to the ASA, the default login password for Telnet was removed; you must manually set the password before you can log in using Telnet. Note : The login password is only used for Telnet if you do not configure Telnet user authentication the aaa authentication telnet console command. For initial ASASM access, you must use the service-module session command, until you set a login password. We modified the following command: passwd. The X9. Support for SHA image integrity checking was added.
We modified the following command: verify. There is no configuration required on the ASASM for this feature; see the switch configuration guide for more information.
The cpu profile activate command now supports the following:. You can now configure DHCP relay servers per-interface, so requests that enter a given interface are relayed only to servers specified for that interface. We introduced or modified the following commands: dhcprelay server interface config mode , clear configure dhcprelay , show running-config dhcprelay. You can now preserve Option 82 and forward the packet by identifying an interface as a trusted interface.
We introduced or modified the following commands: dhcprelay information trusted , dhcprelay informarion trust-all , show running-config dhcprelay. The ASA X now supports additional interfaces on network modules in slot 1.
You can install one or two of the following optional network modules:. For demonstration purposes only, you can enable monitor-only mode for the service policy, which forwards a copy of traffic to the ASA CX module, while the original traffic remains unaffected.
Another option for demonstration purposes is to configure a traffic-forwarding interface instead of a service policy in monitor-only mode. Support for NetFlow flow-update events and an expanded set of NetFlow templates. Two new fields were added for IPv6 translation support. Decreased the half-closed timeout minimum value to 30 seconds.
The half-closed timeout minimum value for both the global timeout and connection timeout was lowered from 5 minutes to 30 seconds to provide better DoS protection.
We modified the following commands: set connection timeout half-closed , timeout half-closed. We modified the following command: crypto ikev1 limit. The IKE v2 Nonce size has been increased to 64 bytes. Higher strength algorithms will be downgraded to the IKE level. This new algorithm is enabled by default. We recommend that you do not disable this feature. We introduced the following command: crypto ipsec ikev2 sa-strength-enforcement.
For Site-to-Site, IPsec data-based rekeying can be disabled. We modified the following command: crypto ipsec security-association. This release adds support for Windows 8 x86 bit and Windows 8 x64 bit operating systems. CSD 3. Flow-update events have been introduced to provide periodic byte counters for flow traffic. You can change the time interval at which flow-update events are sent to the NetFlow collector.
You can filter to which collectors flow-update records will be sent.
