The timer only starts again when you reactivate the time-based license. If the time-based license is active, and you shut down the ASA, then the timer continues to count down. If you intend to leave the ASA in a shut down state for an extended period of time, then you should deactivate the time-based license before you shut down. How Permanent and Time-Based Licenses Combine When you activate a time-based license, then f eatures from both permanent and time-based licenses combine to form the running license.
Unified Communications Proxy Sessions The time-based license sessions are added to the permanent sessions, up to the platform limit. Security Contexts The time-based license contexts are added to the permanent contexts, up to the platform limit. All Others The higher value is used, either time-based or permanent. Stacking Time-Based Licenses In many cases, you might need to renew your time-based license and have a seamless transition from the old license to the new one.
For example: 1. Similarly: 1. Time-Based License Expiration When the current license for a feature expires, the ASA automatically activates an installed license of the same feature if available. Shared AnyConnect Premium Licens es A shared license lets you purchase a large number of AnyConnect Premium sessions and share the sessions as needed among a group of ASAs by configuring one of the ASAs as a shared licensing server, and the rest as shared licensing participants.
Communication Issues Between Participant and Server See the following guidelines for communication issues between the participant and server: If a participant fails to send a refresh after 3 times the refresh interval, then the server releases the sessions back into the shared license pool.
If the participant cannot reach the license server to send the refresh, then the participant can continue to use the shared license it received from the server for up to 24 hours.
If the participant is still not able to communicate with a license server after 24 hours, then the participant releases the shared license, even if it still needs the sessions.
The participant leaves existing connections established, but cannot accept new connections beyond the license limit. If a participant reconnects with the server before 24 hours expires, but after the server expired the participant sessions, then the participant needs to send a new request for the sessions; the server responds with as many sessions as can be reassigned to that participant. Information About the Shared Licensing Backup Server The shared licensing backup server must register successfully with the main shared licensing server before it can take on the backup role.
Failover and Sha red Licenses This section describes how shared licenses interact with failover and includes the following topics: Failover and Shared License Servers Failover and Shared License Participants Failover and Shared License Servers This section describes how the main server and backup server interact with failover. Failover and Shared License Participants For participant pairs, both units register with the shared licensing server using separate participant IDs.
Maximum Numbe r of Participants The ASA does not limit the number of participants for the shared license; however, a very large shared network could potentially affect the performance on the licensing server.
Failover or ASA Cluster Licenses With some exceptions, failover and cluster units do not require the same license on each unit. The exceptions to this rule include: Security Plus license for the ASA and X—The Base license does not support failover, so that you cannot enable failover on a standby unit that only has the Base license.
Encryption license—Both units must have the same encryption license. The exceptions to this rule include: Clustering license—Each unit must have a clustering license. Encryption license—Each unit must have the same encryption license. If all licenses in use are time-based, then the licenses count down simultaneously. For time-based licenses that are enabled or disabled and do not have numerical tiers , the duration is the combined duration of all licenses.
Loss of Communication Between Failover or ASA Cluster Units If the units lose communication for more than 30 days, then each unit reverts to the license installed locally. In this case, communication is restored after 4 weeks. After 30 days—The time elapsed is subtracted from both units. In this case, communication is restored after 6 weeks. Upgrading Failover Pairs Because failover pairs do not require the same license on both units, you can apply new licenses to each unit without any downtime.
Licenses FAQ Q. Guidelines and Lim itations See the following guidelines for activation keys. Context Mode Guidelines In multiple context mode, apply the activation key in the system execution space. Shared licenses are not supported in multiple context mode. Firewall Mode Guidelines All license types are available in both routed and transparent mode.
See Failover and Shared Licenses for more information. Upgrade and Downgrade Guidelines Your activation key remains compatible if you upgrade to the latest version from any previous version. However, you might have issues if you want to maintain downgrade capability: Downgrading to Version 8.
However if you activate feature licenses that were introduced in 8. If you have an incompatible license key, then see the following guidelines: — If you previously entered an activation key in an earlier version, then the ASA uses that key without any of the new licenses you activated in Version 8.
Downgrading to Version 8. Additional Guidelines and Limitations The activatio n key is not stored in your configuration file; it is stored as a hidden file in flash memory. The activation key is tied to the serial number of the device.
Feature licenses cannot be transferred between devices except in the case of a hardware failure. If you have to replace your device due to a hardware failure, and it is covered by Cisco TAC, contact the Cisco Licensing Team to have your existing license transferred to the new serial number. Once purchased, you cannot return a license for a refund or for an upgraded license.
On a single unit, you cannot add two separate licenses for the same feature together; for example, if you purchase a session SSL VPN license, and later purchase a session license, you cannot use 75 sessions; you can use a maximum of 50 sessions.
You may be able to purchase a larger license at an upgrade price, for example from 25 sessions to 75 sessions; this kind of upgrade should be distinguished from adding two separate licenses together. Although you can activate all license types, some features are incompatible with each other. By default, if you install the AnyConnect Essentials license if it is available for your model , it is used instead of the above licenses.
You can disable the AnyConnect Essentials license in the configuration to restore use of the other licenses using the webvpn , and then the no anyconnect-essentials command. You have to enter each key as a separate process. The serial number of your ASA Your e-mail address An activation key is automatically generated and sent to the e-mail address that you provide. Activating or Deactivating Keys This section describes how to enter a new activation key, and how to activate and deactivate time-based keys.
Prerequisites If you are already in multiple context mode, enter the activation key in the system execution space. Some permanent licenses require you to reload the ASA after you activate them. Table lists the licenses that require reloading.
Limitations and Restrictions Your activation key remains compatible if you upgrade to the latest version from any previous version. Detailed Steps Command Purpose Step 1 activation-key key [ activate deactivate ] ciscoasa activation-key 0xd11b3d48 0xa80a4c0a 0x48e0fd1c 0xb 0xfc Applies an activation key to the ASA.

Optional license-server refresh-interval seconds ciscoasa config license-server refresh-interval Optional license-server port port ciscoasa config license-server port None of that should be affecting your ability to reach your DMZ web server.
I have not issue reaching the DMZ webserver. The issue I'm having is that the DMZ webserver cannot access the internet. The webserver has functions built in that require it to call external webservices. When it attempts to make the connection the sys log shows that the connection is torn down after 30 seconds and reports a SYN Timeout. It has been some time since I have configured an ASA, but I think that you are sending packets out, but the firewall doesn't know where to send the return traffic.
I could be wrong Never mind. I had a brain fart. For whatever reason I did not notice my nat dmz rule was way off. Corrected it by adding Nat dmz Glad you were able to sniff out the problem and correct it. I've spotted on other feeds as below that the licences transfer between devices and I can't see much online about these needing to match but rather Model, Version and Interface number needs to be the same? I opened a case with Cisco licensing and here was their response.
The licenses stays on the primary but it is also being used by the secondary so all you need to do is configuration. Remove the old secondary from the HA or failover configuration and then add the new secondary on to the failover configuration. I told him that prior to the purchase of the second ASA there was only a single firewall.
Go to Solution. HA - why we looking HA? So being said, how if they have 2 different images or different configuration or specification works as expected.
How to Ask The Community for Help. View solution in original post. Hope information help you, if no further assitance required can we close the issue or you looking any further help on this context? So just to confirm, some failover units do no require the same licence on each unit but in the case of ASAx, this does require the same Security Plus encryption licence on both units for HA to work?
If you have licenses on both units, they combine into a single running failover cluster license. There are some exceptions to this rule. See the following table for precise licensing requirements for failover. Thanks for confirming on the licencing and sorry to check something else, but is that also the case with the OS?
