Cisco Firewall :: Failover License Sync Between Two ASA 5520?
Jun 3, 2013
According to the link here:[URL]Starting with Version 8.3(1), it no longer needs to install identical licenses. Typically, we only buy a license only for the primary unit; for Active/Standby failover, the secondary unit inherits the primary license when it becomes active.So I wanna know if there's some additional configuration to synchronize the licenses such as SSL VPN or Context between the primary one and the second one? Or they can just synchronize by default as soon as I finish the failover configuration and when the primary one gets down, the second one will take over the role including licenses automatically?

I have a running ASA5520 in my network and recently we plan to add a failover pair as a standby unit for the running asa. Both of the ASA have the same specs and software. the only thing that the soon to be secondary ASA does not have is the AnyConnect Essential license. is it still possible for the unit to be the standby unit?
below is the license capture from both of the unit.
Running ASA:
Licensed features for this platform:
Maximum Physical Interfaces : Unlimited
Maximum VLANs : 150

I have a pair of ASA5520, each has a CSC-SSM module, all specs and licences match and the ASA failover between active and passive firewalls works as expected. However, I am unable to get the two content modules to sync. ASA are running 8.4... and attach diagram show cabling. Each CSC-SSM uses it's connected port as a gateway, although I've tried using both primary and standby IP.
When I try to sync the devices as per the Trend Micro instructions I get the error: "InterScan for CSC SSM could not establish a connection with the failover peer device. Please verify network connectivity with the peer and that the peer is functioning properly, then try again."
All interfaces are up/up. I cannot see the other CSC-SSM in either ASA's arp table. Neither CSC-SSM can ping the other, and none of the guides I've found so far details the pre sync config of the CSC-SSMs.

We have ASA running code 8.0.4 with Active/Standby for quite long time. Today when we gave the command wri standby it started sync the config to standby ASA but waited forever.when we checked the show failover, we got the following result.
This host: Secondary - Active
Active time: 1928633 (sec)
slot 0: ASA5540 hw/sw rev (2.0/8.0(4)) status (Up Sys)
Interface PERIMETER-MGMT (10.12.8.1): Normal (Not-Monitored)
Interface OUTSIDE (86.36.xx.xx): Normal (Waiting)
[code].....
When we console to Standby ASA and tried to save (wri mem), we got the following error and also please note the hostname has become default...?
ciscoasa(config)# wri memory
Building configuration...
Command Ignored, Configuration in progress...
[FAILED]
and when we tried to give following command we got this error:
ciscoasa(config)# copy running-config startup-config
Source filename [running-config]?
%Error reading system:/running-config (Configuration temporarily locked)
ciscoasa(config)#
I see here the standby ASA IPS module is down, but can that issue cause not sync the config backup and writing to nvram (save config)..?

According to Cisco, one of the ASAs must have an Unrestricted License [URL]:
"On the PIX/ASA Security appliance platform, at least one of the units must have an unrestricted (UR) license. The other unit can have a Failover Only Active-Active (FO_AA) license, or another UR license. Units with a Restricted license cannot be used for failover, and two units with FO_AA licenses cannot be used together as a failover pair."I am unfamiliar with the different ASA licenses, so with my current license, I am unable to enable failover on my two ASAs. Here is a snippet of the "show version" output on one of my ASAs (they are the same as far as licenses go):
Licensed features for this platform:Maximum Physical Interfaces : UnlimitedMaximum VLANs : 250Inside Hosts : UnlimitedFailover : Active/ActiveVPN-DES : EnabledVPN-3DES-AES : EnabledSecurity Contexts : 5GTP/GPRS : DisabledSSL VPN Peers : 10Total VPN Peers : 5000Shared License : DisabledAnyConnect for Mobile : DisabledAnyConnect for Cisco VPN Phone : DisabledAnyConnect Essentials : DisabledAdvanced Endpoint Assessment : DisabledUC Phone Proxy Sessions : 2Total UC Proxy Sessions : 2Botnet Traffic Filter : Disabled
This platform has an ASA 5550 VPN Premium license.

I used to have this situation where I need to replace faulty ASA5510 (this FW did not failover to standby FW) with the new one.
But the problem is the new ASA5510 came with Base License only not with Security Plus License which is needed to allow this brand new device to be configure failover.
how do I pull out Security Plus License from old FW and switch it to new FW (Base License) and activate to Security Plus License.

Our customer has purchased 2 x L-ASA-AC-E-5520= Anyconnect Essentials VPN Licenses (750 Users)Ive installed both activated licenses as per the cisco guides, I didnt get any errors on the install. I did a reload on both, they are both back up and running as active/standby but when I do a sh ver the license still shows "ASA 5520 VPN Plus License"Am I being dumb and has this worked successfully or should it not now display Anyconnect when I do a sh ver?

Is it possible to setup 2 x Cisco ASA 5520 that are in an Active/Standby failover using sla monitoring?
For example ASA1 outside interface connects to an upstream switch and you setup sla monitor with icmp echo to ping that switch. The switch goes down and you need the other ASA2 to become the Active ASA. Can the sla monitor be automatically integrated with the failover commands for this to happen?

Do I need the security plus license to do HA with two 5520's?I was told by our purchasing department that the 5520 was supposed to be able to do HA out of the box, but when I look I see only the VPN + license. Does that mean I can download the security plus license? Or do I even need it on the 5520.

I have got ASA 5520. I am planning to install Cisco ASA AIP SSM-20 and Cisco ASA Content Security and Control (CSC) Security Services Module on ASA 5520.. However I am also thinking of adding AIP only as I can do the function of content filtering with proxy server. Relating this issue I would like to ask -
1. What would be the benefit of adding CSC ?
2. Do I have to pay the license cost every year for both of these SSM? What would be the cost ?
3. Upto how many SSM can I add into ASA 55020 ?

I am having ASA 5520 with active/standby configured. Around 2 days ago, the ASA stopped responding & all of my websites stopped working. when i checked the failover status it said that failover is off. I had to manually turn the failover to start my traffic flow.During this time my secondary ASA was not responding. After some time, the primary stopped responding & secondary became active......to solve this i had to make the secondary unit as failover unit primary & the primary unit as failover unit secondary. i did get a log on ASA :-
“(Primary) Disabling Failover” with error message no.105001 which states the below:-
Error Message %PIX|ASA-1-105001: (Primary) Disabling failover.
Explanation In version 7.x and later, this message may indicate the following: failover has been automatically disabled because of a mode mismatch (single or multiple), a license mismatch (encryption or context), or a hardware difference (one unit has an IPS SSM installed, and its peer has a CSC SSM installed).(Primary) can also be listed as (Secondary) for the secondary unit.

I have 2 ASA5520's in failover pair.After failing over I cannot run ADSM on the secondary (now active device), I get "unable to launch device manager from [primary address]"
I can ASDM to the primary device (now marked as "standby ready") on the failover address. I can SSH to it also.I CANNOT ASDM to the secondary device (now marked as "active") on the primary address. I CAN SSH to it.
When I run "sh asdm image" I get valid output (asdm image disk0:/asdm-645.bin) on both.However when I run "sh ver" on each it appears ASDM is not running on the secondary device :
Cisco Adaptive Security Appliance Software Version xxxx [only]
Compared with :
Cisco Adaptive Security Appliance Software Version xxxx
Device Manager Version 6.4(5)
It appears as though ASDM is only running on the primary device (regardless of the fact it is now in standby mode). Is this normal?
I am having to run in a failover condition due to a intermittent hardware fault on the primary unit but require access to the ASDM for monitoring/diag purposes during this condition.

Cisco still doesn't provide failover (active/standby) between two different types of ASA, right?
[URL]
"The two units in a failover configuration must have the same hardware configuration. They must be the same model, have the same number and types of interfaces, and the same amount of RAM"

I have 2 Cisco 5520 ASAs and was configured for Fail over. Unfortunately our Primary ASA went down and Secondary becomes Active and network admin made lots of changes on Secondary Active ASA. What is the best practice to rejoin Primary as standby or active without loosing the existing configuration on Secondary Active ?

We have recently got 2 of our Cisco ASA 5520 firewalls through RMA. These are supposed to run in a Active/Active Failover Pair. There was only 1 RMA request that was opened for both the firewalls. We have received only 1 Activation key for this RMA request for both the firewalls. Just want to check with you if this Activation key will work on both firewalls or do we need a get a seperate one for the other box.

I have a problem with my asa phone proxy. i have two ASA 5520 in HA. I have 10 phone register with ASA active primary. if i execute the command show phone-proxy secure-session. i can see the phone session on the ASA.
if i perform the same command on the passive ASA i can't see the session replicated from the active member.
If i switch the cluster the phone enter in a registrating loop and can't connect to the ASA now active.
If i switch back immediately (the session are still present on the first asa) the phone register again and all works
the ASA have version 8.4(5)
the phone are a 7921g
is normal that the skinny don't start again and re-register the phone on the ASA that became active after failover?

I have one ASA 5520 up and runnign, with complete configuration (ssl customization, DAP, CSD...) with bunch of files on flash drive, etc. I am using software 8.3Now I received one 5520 that I want to use failover, it is with 8.3, I will make sure that ASDM is also the same on both...
So, my question is how to make my running ASA to become primary and to push all info (config, files on flash, etc) to new ASA?
I found few examples, but nothing tells me how to force one ASA to be the source for sync.

What process I need to follow to rebuild my failover unit? I've had to turn it off because it seems that both the primary and secondary were thinking they should both be the active unit. I'm not sure why. But in turning off the failover, I had internet access again. So I think I want to rebuild the secondary unit's configuration. Do I need to turn off failover from the primary unit first? Disconnect the secondary unit, console into it and remove the configuration (command to remove from flash?)? Rebuild the interfaces..all interfaces or just STATE between the units? Just trying to get a list of the process

So i setup a failover active / passive with 2 ASA5520's
Primary asa has 750 Anyconnect vpn licensing and the secondary asa has 2 Anyconnect licenses
I haven't setup the second asa with the new 750 licenses i purchased but when i do a show version it shows that the failover licensed features shows 750...
Does this mean i do not have to install the secondary anyconnect licenses on the standby ASA unit?
output of secondary asa

we have two ASA 5520, on the failover unit is showing LU allocate xlate failed. We read on [URL] that it could be a memory problem , but have cheked it and we have 85% of memory free on both nodes. We also can see all xlate on failover unit.
We have forced failover this evenig and we can´t stablish outbound connexions by outside interface, we think xlates or nat cant work properly.
