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?
Currently we have one ISP1 and all traffic goes to this way. Suppose our isp1 goes down, our outside user cant get the server. All servers are nated to this ISP1.We planned to purchase a another ISP2. Shall we Configure same inside server to map this ISP2? so that one primary ISP1 goes down it will take place the outside trafficISP2.

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?

"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 am trying to setup a failover pair on Cisco asa 5520 - need a state full failover. Do i need two ports dedicated to obtain the above - one for LAN based failover and one for state full fail over ? also do i need a switch in between to connect them ?
View 11 Replies View RelatedI 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 ?
View 6 Replies View RelatedI 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

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?
View 4 Replies View RelatedWe 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?

how to do the interface failover in ASA 8.4 version.
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

We have forced failover this evenig and we can´t stablish outbound connexions by outside interface, we think xlates or nat cant work properly.
I am getting ready to setup avtice/standby failover on our ASA 5520's and have run in to an issue.I currently only have one External IP address available. My Idea was to use a private/placeholder IP address for the standby external IP Address, will this cause any issues with the failover? I know I won't be able to access the secondary from the outside, but that is not an issue.

I am trying to setup an active/standby failover with 5520's running 8.4(2) and am having problems with it not dropping connections during the failover. I am using a portchannel from the switch to each ASA and using sub-interfaces off that. I'm using the command Failover mac address Port-Channel1 “mac-address on primary Port-Channel1” “mac-address on standby Port-Channel1”.The command goes through but doing a show interface port-channel1 doesn't show a change in the mac address on the secondary unit after a failover when it becomes active.

View 6 Replies View RelatedI'm attempting to configure two ASA 5520 for active/standby failover.When I enter the “failover” command to enable the config on the primary ASA, the entire routing table disappears.There is no routing process running, only static routes are configured.
Is this an expected behavior of the failover process and if so, how long should I wait for the routes to come back?
I have 2 asa 5520 firewalls including and 1 AIP-SSM-10 module in each of them. the configuration is set using active/active failover and context mode.
Both of them run individualy the IPS module. The IPS is configured using inline mode and fail-open option. However when one of the module fails and the state is changing from up to init or anything else making the IPS to fail then failover is detected and ASA consider it as failover and bounce context to the other unit.
IPS soft is 6.0(4) and ASA soft is 8.0(3)
I have checked cisco doc and it is confusing to me. it says: "The AIP-SSM does not participate in stateful failover if stateful failover is configured on the ASA failover pair." but it really does participate. Running is not really an option because of production network impact matter..
When I try to put my ASAs in active/standby config here is the error I get.Warning: Failover message decryption failure. Pleas make sure both units have the same failover shared key and crypto license or the system is out of memory.

View 4 Replies View RelatedI currently have a set of firewalls in active standby configuration running an ospf process injecting a default route into the rest of my network.I noticed when i was testing the failover that the asa's do not actually pass the route tables on failover, thus forcing the need to wait for routes to converge and for the default route to be advertised back into the network. This of course is not acceptable.
Is there a way around this or do I have to setup static default routes on every device in my network. I am trying to avoid setting up default routes on all of the devices because due to the setup of my network I have equal cost links configured in the event of hardware or link failure. So the devices then see an advertised default route from multiple paths.

We have AT&T Managed MPLS service are our datacenter and our branch office locations. AT&T has provided the routers and simply give us an ethernet connection. We also have ethernet connectivity to the internet through our datacenter...with our network being protected by an ASA 5520.Each branch location has a 29xx series router (voice gateway) and switching gear attached to their AT&T MPLS router. Some of our branches also have 3rd party cable internet service with an ASA 5505 to protect it from the internet. What I'd like to do is better utilize this cable modem/ASA5505 setup. Right now, if there were an outage, I would be connecting manually to the remote location to change static routes to point to the cable link and to configure a VPN tunnel between the remote and our DC.
