Cisco Firewall :: Failover Between ASA 5510 And 5520?
Sep 27, 2012
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"
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.
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?
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:-
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.
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 ?
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 ?
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
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?
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.
Recently, I unable to configure the failover on bridge group in transparent mode . I have five interfaces .out of this only 3 is showing in the show run config . Whether I can config failover on on of the data interfaces.
I have the ASA 5520 with the version ASA Version 7.2(4) <context>
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 made an ASDM upgrade for one of my two CISCO ASA 5520. If I copy a file to the primary ASA's flash, is there any command I can run on the primary ASA to copy a file to the secondary ASA?
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.
From ASA 5520 we tested the interface failover it not working even the interface are getting monitor .
primary is active.
Manually we shut the outside interface of the primary device configuration is getting reflecting in secondary as outside interface shut. Interface failover not happen.
ii All the interface are getting monitor when we gave command sh failover. even though when we shut outside interface failove not happening.
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
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 : Licensed features for this platform:Maximum Physical Interfaces : Unlimited perpetualMaximum VLANs : 150 perpetualInside Hosts : Unlimited perpetualFailover : Active/Active
I was trying to assing statefull link as same as LAN failover link on ASA5520 with VPN Plus license. But i am getting the below error. Is there any restriction in the license itself.
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.
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.
We apply a new anyconnect mobile license to our primary asa 5520 and the failover feature went into an off state. WE have now applied a second purchased anyconnect mobile to our secondary asa but the failover is still inactive/off.

Configured ASA 5510 ISP failover and working fine.My ASA as configured as DHCP server also. So its serves IP addressing details including mask,default-gateway, DNS server IPs.Here my issue is whenever my ISP failover occurs my ASA sends previous ISP DNS server IPs to my inside clients.
Here i like to configure my ASA to serve IP addresses dynamically.Or is there any global DNS IP addresses which will work for all ISPs?
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.
Currently l have two ASA 5520's in a active/passive failover scenario. Currently the interfaces for the inside and outside are fixed at 100/FULL.I want to repatch them into GigE ports setup as Auto Negotiate.Is there anyway of keeping the connections through the firewall active in this type of scenrio or will l have downtime disconnecting and repatching? or could l possibly disable failover and reconfigure each ?
Can I run Cisco ASA failover with dual ISP run active/standby configuration and SLA monitor to monitor the primary ISP gateway and failover to the secondary gateway but not failover to the failover firewall unless an actual event occurred that required a ASA failover?
I have two ASA 5510's that I want to setup in a Active/Standby configuration. My only question is on how to connect the inside ports to my LAN. I have 5 Catalyst 3750's stacked together that connect to the ASA's. Should I run the inside interface on ASA1 to a port on switch 1. Then run the inside interface on ASA2 to a port on switch2? And make sure both those ports are in the same VLAN? But, then when failover occured, how to I automatically make it clear the arp cache so the traffic starts flowing out of the right port?
I have a customer with two ASA 5510s. All four ports are used by the following interfaces: inside, outside, dmz, and failover. This customer is looking at getting redundant internet connections, but we don't have any ports to the redundant connection. What I'd like to know is it possible to configure sub interfaces on one of the currently occupied ports (I'm thinking inside) and use one for inside and one for failover. This way I could have the other port free for the redundant internet connection.
We are going to buy a new Firewall ASA5510 to use failover possibilities.I just need to be sure it will be possible to implement as I have the following output after a "show ver" command: Cisco Adaptive Security Appliance Software Version 8.3(1) [code]
As you can see the failover line is set as "Disabled perpetual".We are actually using base license as i have not been able to find any contact for CISCO to get official support or new license.
I have a customer who has purchased a Cisco 5510 and after we received it and all the necessary VPN, 3DES etc. licensing for it, then informed us that they order 2 T1 lines so they can have Internet failover.
My question is: Does this require an additional specialized license from Cisco in order to enable and configure it? And if so, what that part number is?
I am planning to achieve the failover either of the following ways -
1) Configuring both ASA FW as active/standby method .
2) configuring ASA FW 1 tracking command pointing to the ISP end ip address so the traffic would be moved to secondary firewall by putting a AD as 1 on ASA FW ......pointing to the ISP ip address and other floating route ( with a higher AD value) to the secondary firewall interface.
I am looking for redundant asa deployment for fail over set up . however both units have csc cards. does this product ASA5510-CSC10-K9 has license for fail over ? what's the part no for asa failover license ?
