The output for show fragment command was enhanced to include IP fragment related drops and error counters. The output for show tech-support command was enhanced to include the bias that is configured for the crypto accelerator. The bias value can be ssl, ipsec, or balanced. Due to communication delays caused by high CPU usage, the response to the keepalive event fails to reach ASA, resulting in trigerring failover due to card failure.
You can now configure the keepalive timeout period and the maximum keepalive counter value to ensure sufficient time and retries are given.
You can now configure the maximum in-negotiation SAs as an absolute value up to or a maximum value derived from the maximum device capacity; formerly, only a percentage was allowed. If a CSRF attack is detected, a user is notified by warning messages. This feature is enabled by default. You can optionally configure the ASA to validate the identity of the server during domain join.
We modified the kcd-server command to add the validate-server-certificate keyword. This section provides the upgrade path information and a link to complete your upgrade. CLI—Use the show version command. See the following table for the upgrade path for your version.
Some older versions require an intermediate upgrade before you can upgrade to a newer version. Recommended versions are in bold.
ASA 9. To complete your upgrade, see the ASA upgrade guide. The open and resolved bugs for this release are accessible through the Cisco Bug Search Tool. This web-based tool provides you with access to the Cisco bug tracking system, which maintains information about bugs and vulnerabilities in this product and other Cisco hardware and software products. You must have a Cisco. If you do not have one, you can register for an account. If you do not have a Cisco support contract, you can only look up bugs by ID; you cannot run searches.
The following table lists select open bugs at the time of this Release Note publication. ASA traceback when running "no threat-detection statistics tcp-intercept" command. Clear crypto ipsec sa inactive command not deleting outbound SAs. Failover: standby unit crashed during modifying access-lists, with high CPU utilization.
Improper ordering of context between primary and secondary ASA units in multi-context mode. Crypto engine errors when GRE header protocol field doesn't match protocol field in inner ip header.
ISA hardware-bypass behavior is not changed after write erase. When a connection is enabled, processing events such as a connection lock, unlock, and delete are recorded into the two history lists. When a problem occurs, these two lists can be used to look back at the processing to determine the incorrect logic.

Crash observed while performing master role change with active IGMP joins. Upon downgrade of an ASAv, the firewall may traceback and reload. FTD traffic outage due to block size depletion caused by the egress-optimization feature. FPR , low block causes packet loss through the device.
Adding an ipv6 default route causes CLI to hang for 50 seconds. SNMP: Cannot get failover link information from oid in multiple mode. Multiple context ASA, transparent context losing mangement interface configuration. We need to have default route with AD and tunneled at the same time for the same next hub. Policy deployment is reported as successful on the FMC but it is actually failed.
Mac address flap on switch with wrong packet injected on ingress FTD interface. ASA after reload had license context count greater than platform limits. Secondary unit exceed platform context count limit in split brain scenario when failover link down.
Configuration might not replicated if packet loss on the failover Link. FTDv Deployment in Azure causes unrecoverable traceback state due to no dns domain-lookup any". Clustering module needs to skip the hardware clock update to avoid the timeout error and clock jump.
FP Traceback and reload when processing traffic through more than two inline sets. After upgrade to version 9. ICMP not working and failed with inspect-icmp-seq-num-not-matched. Secondary ASA is unable to join the failover due to aggressive warning messages.
IKEv2 vpn-filter drops traffic with implicit deny after volume based rekey collision. Reduce number of fsync calls during close in flash file system. Invalid scp session terminates other active http, scp sessions. Deployment is marked as success although LINA config was not pushed. SCTP heartbeats failing across the firewall in Cluster deploymnet. IPv6 DNS server resolution fails when the server is reachable over the management interface.
Flow offload not working with combination of FTD 6. Incorrect access-list hitcount seen when configuring it with a capture on ASA. DOC - Clarify the meaning of mp-svc-flow-control under show asp drop. VPN failover recovery is taking approx. Crypto ring stalls when the length in the ip header doesn't match the packet length.
FPR 'show crypto accelerator statistics' counters do not track symmetric crypto. The following table lists select resolved bugs at the time of this Release Note publication.
ASA Traceback watchdog timeout when syncing config from active unit inc. ASA Multicontext traceback and reload due to allocate-interface out of range command. Deployment on FTD with low memory results on interface nameif to be removed - finetune mmap thresh. ASA may traceback in thread logger when cluster is enabled on slave unit.
EIGRP breaks when new sub-interface is added and "mac-address auto" is enabled. Lina does not properly report the error for configuration line that is too long. ASA traceback and reloads when issuing "show inventory" command. ASA may traceback and reload. Potentially related to WebVPN traffic. Standby Firewall reloads with a traceback upon doing a manual failover. ASA unable to authenticate users with special characters via https.
The delay command in interface configuration is modified after rebooted. AnyConnect connections fail with TCP connection limit exceeded error. Option to display port number on access-list instead of well known port name on ASA. Unable to process gtpv1 identification req message for header TEID : 0. FIPS mode gets disabled after rollback from a failed policy deploy.
Cluster master reload cause ping failure to the Management virtual IP. Traceback: "saml identity-provider" command will crash multi-context ASAs.
After failover, Active unit tcp sessions are not removed when timeout reached. Traceback: Cluster unit lina assertion in thread name:Cluster controller. Connections fail to replicate in failover due to failover descriptor mis-match on port-channels. Cannot add neighbor in BGP when the neighbor is on the same subnet as one interface. Multiple PAT rules with "any" and named interface cause "portmap translation creation failed". To-the-box traffic being routing out a data interface when failover is transitioning on a New Active.
Standby traceback in Thread "Logger" after executing "failover active" with telnet access. Usage of 'virtual http' or 'virtual telnet' incorrectly needs 'same-security permit intra-interface'. Withdrawal advertisements for specific prefixes are flooded before flooding aggregate prefix.
Should correctly report full model name. The CPU profiler stops running without having hit the threshold and without collecting any samples. Initiating write net command with management access for BVI interfaces does not succeed. Make Object Group Search Threshold disabled by default, and configurable. If other optional parameters are supplied, then these values are used in place of the corresponding tftp-server command setting. If any of the optional parameters, such as a colon and anything after it are supplied, the command runs without a prompt for user input.
The location is either an IP address or a name that resolves to an IP address via the security appliance naming resolution mechanism, which is currently static mappings via the name and names commands.
The security appliance must know how to reach this location via its routing table information. This depends on your configuration. The pathname can include any directory names besides the actual last component of the path to the file on the server. The pathname cannot contain spaces.
If a directory name has spaces set to the directory in the TFTP server instead of in the copy tftp flash command, and if your TFTP server is configured to point to a directory on the system from which you download the image, you only need to use the IP address of the system and the image filename. The TFTP server receives the command and determines the actual file location from its root directory information.
The server then downloads the TFTP image to the security appliance. These commands are needed to upgrade the software image as well as the ASDM image and make it as a boot image at the next reload. This command allows you to specify parameters, such as remote IP address and source file name. This procedure is similar to TFTP. In TFTP mode, options specified with the tftp-server command can be pulled and executed.
But with FTP, there is no such option. The source interface should always be the outside by default, which cannot be modified. That is, the FTP server should be reachable from the outside interface. After the ASA reloads and you have successfully logged into ASDM again, you can verify the version of the image that runs on the device. See the General tab on the Home window for this information.
