Cisco Asa License Upgrade Failover Internet' title='Cisco Asa License Upgrade Failover Internet' />Cisco ASA Licensing Explained Packet Pushers Cisco ASA firewall licensing used to be pretty simple, but as features were rolled out as licenses, the scheme became quite complex.The matters are further complicated since different appliances and versions change the rules.This document will help you make sense of ASA licensing, but is not intended to be used as a design guide.Make sure you work with your reseller if you are looking to deploy these features.Book Title.

Cisco ASA firewall licensing used to be pretty simple, but as features were rolled out as licenses, the scheme became quite complex.The matters are further.Cisco ASA 5500X Series NextGeneration Firewalls Some links below may open a new browser window to display the document you selected.Security Plus. Security Plus licensing exists only on 5.On the 5. 50. 5 it has the following effects Upgrades the maximum VPN sessions from 1.Upgrades the maximum connections from 1.Increases the number of VLANs from 3 to 2.Enables optional stateless activestandby failover.On the 5. 51. 0 it has slightly different set of features it enables Upgrades the maximum connections from 5.Moves 2 of the 5 Fast.Ethernet ports to 1.Increases the number of VLANs from 5.Enables security contexts and allows for 2.Up to 5 can be supported on the 5.Enables optional activeactive and activestandby failover.Enables VPN clustering and load balancing.The 5. 52. 0 and up do not have Security Plus licensing.They come with the Base license and need nothing more to get the most performance out of the unit.Update As Stojan pointed out in the comments, the 5.X series does have Security Plus licenses which enables the 1.GB SFP slots. 5. User Licenses.The 5. ASA which has a restriction on the number of users behind a firewall.A user is considered an internal device which communicates with the external VLAN.By default the 5.SSL VPN Licenses.SSL VPN debuted on the ASA when it was first released but has evolved more than any other licensed based feature on the ASA.SSL licenses break into two general types Essentials and Premium.Essentials provides Any.Connect client based connections from personal computers including Windows and Mac systems.Installing an Essentials license allows for up to the maximum number of VPN sessions on the platform to be concurrently used for SSL.For example, a 5.SSL VPN connections from the Any.Connect client. These licenses are relatively inexpensive, currently priced around a hundred dollars with the price varying per platform.These are platform specific SKUs so make sure the one youre buying matches the device it is going on.For example, on the 5.L ASA AC E 5. Any.Connect Essentials licenses debuted with ASA release v.Premium licenses are more complicated than Essentials.Premium licenses allow for both Any.Connect client based and clientless SSL VPN.Clientless VPN is established through a web browser.While it is typically less functional than Any.Connect client based VPN, it is adequate access for many users.Additionally, Cisco Secure Desktop Host Scan and Vault functionality is included.Premium licenses do not max out the unit theyre on of SSL VPN sessions as does the Essentials license.Instead, this is a per seat license that can be purchased in bulk quantities.These quantities are 1.VPN connections ex.These tiers must be observed when adding additional licensing.For example, if an administrator needed 3.The 1. 0 and 2. 5 cannot be stacked.Cisco does offer upgrade licenses to upgrade tiers.Premium licenses are significantly more expensive than Essentials.Contact your reseller for pricing on Premium licenses.If a VPN license is activated on an ASA, it will overwrite any existing VPN license.Be careful HA Pair License Dynamics.Prior to ASA software v.HA pair. A 5. 51.SSL VPN enabled wouldnt pair with a 5.SSL VPN. As of v.HA pair. On a 5. 50.ASAs require Security Plus licenses since Security Plus enables the HA functionality.SSL Essentials and Premium are replicated between licenses.In an activeactive pair, license quantities when applicable are merged.For example, two 5.SSL Premium seats each.The licenses will merge to have a total of 2.SSL VPNs allowed in the pair.The combined number must be below the platform limitation.If the count exceeds the platform limit ex.SSL VPN connections on a 5.Flex Licenses. ASA Flex licenses are temporary SSL VPN licenses for emergencies or situations where there is a temporary peak in SSL VPN connections. Spongebob Squarepants Battle For Bikini Bottom . Each license is valid for 6.Perhaps these are best explained as a scenario.XYZ Corp. had some flooding in their corporate office which houses 6.They own an ASA 5.SSL Premium licenses.Ciscos Flex licenses will allow them to temporarily burst the number of licenses their 5.The key for 7. 50 users is added to the 5.The 5. 52. 0 is now licensed to support up to 7.SSL VPN users on client based or clientless VPN.After 6. 0 days the key will expire.If XYZ Corp. has their building up and running again earlier than 6.This will pause the timer on the Flex licenses, allowing them to use the remainder of the time in the future.Ciscos Flex license documentation is pretty good and explains some of the gotchas around the licenses.Be sure to read it before purchasing and using the license.Any. Connect Premium Shared Licenses.Large deployments of SSL VPN may require multiple ASAs positioned in multiple geographic areas.Shared licenses allow a single purchase of SSL VPN licenses to be used on multiple ASAs, possibly over large physical areas.Starting with software v.Cisco allows the shared license to ease this situation.Shared licenses are broken into two types main and participant.The main license starts at 5.SSL Premium sessions and scales to 1.The main license acts as a license pool which participants pull from in 5.A secondary ASA can act as a backup in case the primary fails.There is no specific backup license, as the ASA only requires a participant license.If there is no secondary ASA, the participant ASAs may not be able to reach the main ASA in the event of a connectivity problem.The participant ASA is able to use the sessions that were last borrowed from the main for 2.Beyond 2. 4 hours, the sessions are released.Currently connected clients are not disconnected but new connections are not allowed.In ActiveStandby mode, the server ASA is actually the ASA pair.The backup ASA would be the backup pair.The standby server in a pair wouldnt be the shared license backup.The manual explains this concept pretty well For example, you have a network with 2 failover pairs.Pair 1 includes the main licensing server.Pair 2 includes the backup server.When the primary unit from Pair 1 goes down, the standby unit immediately becomes the new main licensing server.The backup server from Pair 2 never gets used.Only if both units in Pair 1 go down does the backup server in Pair 2 come into use as the shared licensing server.If Pair 1 remains down, and the primary unit in Pair 2 goes down, then the standby unit in Pair 2 comes into use as the shared licensing server.USdocssecurityasaasa.Advanced Endpoint Assessment.Advanced Endpoint Assessment will scan a SSL VPN client using Cisco Secure Desktop for security policy compliance and attempt to remediate if the system is out of compliance.This is similar but a little less feature rich than NAC.Licenses are simple for Advanced Endpoint Assessment.One license per ASA is required in addition to SSL Premium.If the ASA is in a HA pair, one license per pair is required if using ASA software v.Security Contexts.Security Contexts are virtual firewalls.Each context allows for its own set of rules and default policies.Security Contexts are sold in quantities of 5, 1.Cisco sells incremental licensing to move between tiers.Note that two security contexts are used when in a HA pair.Unified Communications Proxy Licenses.Cisco UC Proxy allows for Cisco IP phones to create a TLS tunnel between a remote phone and the ASA located at a corporate office.Typically if a secure connection between a phone and office were required, a firewall would have to sit at the users location.In many cases this would be a 8.This deployment architecture doesnt scale well due to management costs and cost of routers with their corresponding SMARTnet.UC Proxy bypasses the router and uses the IP phone as the VPN endpoint.UC Proxy licenses are sold in numerous tiers ranging from 2.The licenses cannot be stacked, but incremental licenses can be purchased.Any. Connect Mobile Licenses.Out of the box, ASAs do not accept connections from mobile devices such as i.OS or Android systems.The Any. Connect Mobile client must be installed on the clients device.In addition to the client, the ASA must have Any.
