LICENSE UPGRADE ON ASA FAILOVER PAIR

Hi all,

We have a pair of 5515-X in production, wanted to upgrade the license to support more anyconnect/ mobile users.

The data sheet for the anyconnect: clear mention it's a shared license while the mobility isn't. Knowing that i need the ASA serial number and the PAK to get the new license file from cisco, does that mean i can use the same license on both device? Or if i upgrade one device(active), the stanby device won't get mess up?

Thanks,

Thanks for posting the additional information. It does help clarify some things. I assumed that you were already operating AnyConnect and Mobile. But this makes it clear that you have only the built in license for 2 AnyConnect SSL VPN on each ASA and no license for Mobility.

 

The 25 seat license that you mention will allow you to support 25 concurrent AnyConnect sessions and the single license will allow both ASAs to operate and to support those 25 concurrent users. You would install the license on one ASA (probably the primary ASA) and both ASAs would be able to use the license. (As a note about this remember that only one ASA at a time will be carrying the AnyConnect sessions, which is one of the reasons why only one license is required.)

 

Perhaps there is some small confusion about the AnyConnect Premium and AnyConnect Essentials licenses. You would use one or the other but you can not operate both Premium license and Essentials license on the same ASA. So since you are ordering the Premium license you do not want the Essentials license.

 

Also note that if you want to support VPN on mobile devices that you will need the Mobility license for the ASAs.

First we need to check on a

First we need to check on a couple of assumptions:

- the ASA5515X are configured and operating in Active/Standby High Availability operating mode.

- you already have licenses for AnyConnect and Mobility installed and operating.

- you are upgrading the AnyConnect license to support greater number of users.

If these are correct then you should be able to use the serial number of one of the ASA (probably the primary) to generate the PAK/license. You then install the new license on the ASA and the backup will share the new AnyConnect license and continue to use its Mobility license. The standby should not get messed up.

 

Be aware that this works pretty well as long as both ASA are operational. If something happens and the primary goes out of service (you are doing maintenance or something happens to the primary) the standby will continue to operate using the shared license. But a clock is running and after some time (I do not remember the specifics but it is measured in days not hours) if the primary, with its license, is not back then the standby will effectively have no license and AnyConnect will stop working on the standby.

Thanks Richard... And i think

Thanks Richard... And i think you are right but i need to confirm...

When i do a show license on the boxes(active and standby)... They both mention Anyconnect premium enable as per below

Failover cluster licensed features for this platform:
Maximum Physical Interfaces       : Unlimited      perpetual
Maximum VLANs                     : 100            perpetual
Inside Hosts                      : Unlimited      perpetual
Failover                          : Active/Active  perpetual
Encryption-DES                    : Enabled        perpetual
Encryption-3DES-AES               : Enabled        perpetual
Security Contexts                 : 4              perpetual
GTP/GPRS                          : Disabled       perpetual

IPS Module                        : Disabled       perpetual
Cluster                           : Enabled        perpetual

This platform has an ASA 5515 Security Plus license.

 

So i ordered more license to increase the anyconnect premium number of seat(Mfg#: L-ASA-SSL-25= (quantity 1)). So i assume these 25 seats can be shared between the two ASA, right?

Now as per the anyconnect essention as it's disable in both ASA, so i two licenses(one for each ASA to enable it), right?

Thanks,

The part number you mention

The part number you mention will give you 25 AnyConnect Premium licenses for the HA pair.

If you use AnyConnect Premium you cannot simultaneously use AnyConnect Essentials. Both may be licensed but you use only one or the other based on your requirements.

In an HA pair the default shows the 2 included Premium licenses (full-featured but mostly for evaluation purposes as most productions VPNs require more than two concurrent users) that ship with all ASAs added together from the primary and secondary unit: 2+2=4.

If the unit to which you apply the license fails, the secondary unit can continue to use the license for 30 days. If you RMA the failed unit under Smartnet support, Cisco will entitle you to rehost the license onto the replacement unit.

Thank you both a lot.Things

Thank you both a lot.

Things are getting clearer now.

Will go ahead and upgrade the premium license in the Active unit.

I will fight with my VAR to change the essential license to the Any connect mobile.

Hi Rich,

Hi Rich,

My apologies if it's not OK to add post on a thread that was supposed closed 2 years back. If it is OK, Can I ask another question related to original post? I want to install an upgrade license for number of contexts on a failover pair, running in ACTV/STBY, do I need to reload both boxes one-by-one or can only reloading the Active suffice for the license to take effect on both units?

I do understand that reloading one after the other won't bring any downtime, but I just want to avoid reloading the STBY box if there's not an actual need.

Appreciate your help on this.

Regards,

Sanjeev Nandal

Sanjeev,

Sanjeev,

If you are moving from single context to multiple context mode you will need to reload both units as the entire configuration is erased during this mode transition. That's due to the change of how resources are allocated in the system execution space and config files are then assigned to the contexts.

If you are already in multiple context mode and simply add licenses I believe the reload of the Active unit will suffice. You HA pair (whether running Active-Active or Active-Standby) will have the number of contexts you get when adding those on the Primary and Secondary appliances.
