Cisco :: ASA5510 - Event Primary Firewall Fails

Jun 6, 2011

The client is only interested to have one-WAN(MPLS) and One internet circuit with Dual ASA5510 primary/failover configuration. In the event primary firewall fails, there is no direct WAN/internet connection to failover firewall. I beleived that  to mitigate the issue,  I needed to add a layer 3 switch , and have each circuit (MPLS/Internet) or (modems/routers) connect to a L3 switch. L3 switch will do the vlan based routing based on the state of firewall. ? am i correct?  The client want automatic failover to secondary firewall in the event the actual firewall failed without impacting the day to day business.

Cisco Firewall :: Replacement Of Primary Unit Failed ASA5510

Sep 7, 2011

I have an issue bringing up my RMA'd primary ASA unit.
 
So what happened so far:
 
1. primary unit failed
2. secondary took over and is now secondary - active (as per sh fail)
2. requested RMA at Cisco
3. got ASA and checked that Lic (SSL), OS (8.2.2) and ASDM are at the same level as the secondary
4. issued wr erase and reloaded
5. copied the following commands to the new (RMA) primary unit:
failover lan unit primary
failover lan interface Failover Ethernet3
failover interface ip Failover 172.x.x.9 255.255.255.248 standby 172.x.x.10
int eth3
no shut
failover
wr mem
6. installed primary unit into rack
7. plugged-in all cables (network, failover, console and power)
8. fired up the primary unit
9. expected that the unit shows:
Detected an Active mate
Beginning configuration replication from mate.
End configuration replication from mate.
10. but nothing happened on primary unit
 
What is a valid and viable approach in replacing a failed primary unit? Is there a missing step that hinders me to successfully replicate the secondary - active config to the primary - standby unit.
 
I was not able to find anything related to ASA55xx primary unit replacement with a clear guideline or step by step instructions.

Cisco Firewall :: ASA5510 Any Way For Users To Not Get Disconnected / When One Device Fails

Jul 8, 2012

I want to set-up a HA for ASA5510. I wanted to design the network to achieve HA. I am attaching the present set-up of the network. At present, I have 2 ISPs connections terminating in ASA5510. The configuration is done for failover in ASA5510.I have another ASA5510 and want to use it for HA. I needed to know the design for the set-up. I want a stateless failover since the amount of traffic is less. I don't have any ISP routers in the present network. I suppose I need 2 routers for HA and couple of switches. One more question is that, as there are SSL VPN users, is there any way for the users to not get disconnected when one device fails.

Cisco WAN :: 4506 / 2 WAN Links With EIGRP Failover If Primary Fails

Jul 26, 2012

I have a remote site with 2 WAN links.Link 1 MPLS with telecom provider managing the PE and advertising EIGRP routes to my switch(3750-E stack).Link 2 Directly connected to core site switch (4506) and advertising EIGRP routes.
  
It looks like this:
  
-------- Provider MPLS Cloud ------- GI2/0/1Remote Site (3750-E Stack)
Core Site Switch(4506)----
gi4/2------------------------------------------------ GI1/0/1Remote Site (3750-E Stack)
  
When both links are up MPLS is disrupted from other sites (that have MPLS only) to the core site.  I was unable to get a route list to see what exactly was going on before shutting the directly connected link down.What i'd like to have is:Use MPLS as my primary link as it is fully meshed with all my remote sites (and not just the core) and have the directly connected link as my failover in case of issues with the primary. I assumed putting a delay 1000 on the directly connected link at the remote site would have been enough but it looks like both were active and leaking routes all over the place Is there a way to set this up that the MPLS link is favoured and if it loses routes to that specific remote site it would failover to the directly connected link? 
 
Here is my current configuration for EIGRP on the remote and Core sites: 
 
Remote 3750-E
router eigrp 100
redistribute connected
redistribute static
passive-interface default
no passive-interface GigabitEthernet1/0/1

Cisco AAA/Identity/Nac :: Secondary ACS 5.1 Fails To Deregister After IP Change On Primary

Aug 9, 2011

IP address of Primary had to be changed, to respond to a hardware failure of TACACS server with IP in many device configs.
 
Now the Secondary fails to respond to repeated "Deregister from Primary" requests, even after reload  - apparently because it cannot reach the Primary at its old IP address. 
 
Requesting Deregister in GUI generates pop-up that says,  "This operation will deregister this ACS Instance from the Primary Instance. Management applications on this ACS instance will be restarted and you will be required to login again.  After performing this operation

Cisco Application :: ACE 4710 Load Balance Only If Primary Server Fails

Oct 14, 2012

I've done a lot of ACE work over the years but this is the first time this has ever come up. 
 
I have a request from an application group where I have 3 rserver in the server farm but they want all traffic to only go to the first server unless that server fails.  If the first server fails, only then do they want traffic to go to the 2nd server instead and if that fails, then traffic goes to the 3rd.
 
I've read through the documentation but haven't figured out a way to do this. What to do this type of failover configuration?

Cisco Firewall :: Automatic Shutdown ASA5520 On Critical Event?

May 8, 2012

Is it possible to automatically shutdown the OUTSIDE interface on a Cisco ASA 5520 in case of intrusion?.
 
In my opinion if there is an attempt of intrusion, just the device would stop it. If it cannot detect it, how can the device recognize the event and so shutdown the interface?. Am I correct?

Cisco Firewall :: ASA 5515X - Config Loss After Primary Firewall Reloaded

Sep 23, 2012

I have a strange issue which happened to me last weekend with two ASA 5515X on version 8.6(1)2. There was a planned power shutdown which only affected the primary firewall. Failover was configured and running successfully. The configuration was also saved after every change made. After power was shut and primary firewall went off the secondary took over like it should but unfortunately all configuration was gone. We immediately powered on the primary again but also this one lost the configuration.
 
While reconfiguring the firewall we ran into another problem. The devices won't pair although it was the correct configuration. After three times removing and adding the same failover configuration the devices accepted the failover and worked together again.
 
I went through the bug toolkit and white papers regarding ASA 5515x and this particular version but were not able to find anything.

Cisco Firewall :: ASA 7206 Failover When Primary ISP Goes Down

Apr 4, 2012

I have an outside 7206 router that is configured with BGP. Behind that I have an ASA 5520 with a failover. Everytime my primary ISP goes down I have to failover the ASA to restablish a connection to the secondary ISP. When the primary comes back on line I have to fail it over again. I have had Cisco TAC look at the ASA and they didn't see anything misconfigured on the ASA. Doesn't seem to be any problems with the router config either.

Cisco Firewall :: 5505s - Secondary ASA Active And Primary Is On Standby

Dec 5, 2011

We have 2 ASA 5505s in a data center at a remote site.
 
Whilst troubleshooting another issue I noticed the below. I don't know much about fail over but this would suggest that the secondary ASA is active and the primary ASA is on standby.
 
if the primary is "active" then how come the secondary is the active ASA? I would have thought that once the primary ASA became active this would assume the "main" role".

Cisco Firewall :: FWSM On 6500 TCP Connection After Crash On Primary Network

Aug 6, 2012

We are running an FWSM on a 6509 with a SUP720. Firmware 3.2(18), in MultiContext Routed Mode, with shared MSFC.Everything runs fine on this baby most of them time, however occasionally without warning and with no specific pattern the Primary node will fail (as in completely stop responding) and the secondary will takover as active. Two get the primary up agian, I reset the hw-module and then no failover active on the secondary to return the primary as active. However, after this event, I start to experience strange issues with connectivity. Certain TCP src dst combinations will just not work.

Cisco Firewall :: Primary ASA 5510 Turns To Standby When Both Units Power Up

Mar 22, 2011

I have three pairs of ASA5510 firewalls, each pair configured as a failover pair. When each pair boots up, even if I boot up the primary first, when they are both up and the primary/active syncs to the secondary/standby, the primary always switches to standby and the secondary thus becomes active.
 
What would cause this?  It happens on all three pairs. Does failover look for the highest ID or IP address to determine which of the pair will be active?

Cisco Firewall :: Adding Failover ASA 5510 Back After Configuration Changes On Primary

Nov 28, 2012

I had a working active/passive pair of ASA5510's, and then I had to do a rush firmware upgrade, but didn't have time to do it on the secondary at the same time.  Now I have made config changes and upgraded the secondary firmware to be the same, and wish to know if I plug it back in if it will think the secondary has the "correct" config or if it will know that the primary is newer.  I disconnected the failover cable because it was complaining about version mismatches constantly.
 
Is it safe to add the secondary back in or is it possible it will be declared newer and overwrite the config?

Cisco Firewall :: ASA5510 Secondary Firewall Crashes After Upgrade To 8.4.1

Jun 29, 2011

I have two ASA5510's set up in failover, and the secondary keeps crashing after doing the interface checks when bringing failover up. This only happens if I try to upgrade the image on the secondary to anything newer than 8.4.1 (I've tried with 8.4.1-11 and 8.4.2). The primary one run just fine with new images.
 
I don't have the exact error right now, as I need to do a screen capture from console. It's just a huge crash dump.Are there anything I might have missed during the upgrade? Should I cold-boot both the firewalls in the correct order?

Cisco Firewall :: ASA 55xx (8.0.3) Failover When IPS SSM Fails

Aug 27, 2008

Is there a way to trigger stateful (or stateless) failover on ASA 55xx (8.0.3) when there's a failure on the IPS unit?  I understand the fail open/fail close and its application on a single firewall, but the better solution for an IPS failure in a redundant pair would seem to be a stateful failover to the other ASA, and I don't see that as a documented feature.

-interface Ethernet0/2
- speed 100
-shutdown
- no nameif
-no security-level
-no ip address
 
it's ethernet and not fastethernet so I figure it will only go to 10Mbps, but at the same time I can hard code the speed to 100.

Cisco Firewall :: ASA5505 SNMP Polling Fails?

May 31, 2012

I am having issues with monitoring our Cisco ASA5505 devices with "SolarWinds Orion NPM 10.2" through the use of SNMPv2. On some devices we see that SNMP polling stops and that the ASA's interfaces would show up as unknown - usually when the link to the device goes down/up or after a random ammount of time. At that point SNMP polling data is no longer updated and all we can rely on is ICMP for device status. I can resolve the issue by restarting the remote ASA OR restarting the SolarWinds server after which polling resumes. We are only seeing this behaviour with our remote ASA's.
 
Our setup is as follows:
Head End: Cisco ASA 5520 [ASA 8.3(2)]
Remote: Cisco ASA 5505 [ASA 8.3(2)] 
 
I have found a SolarWinds article listed below that possibly identifies the issue that we are having but am not sure where to start.

In case, the client bypasses firewall, the file gets downloaded as usuall.

I was planning to do in active /standby mode for failover .But i have a doubt , when i do "show version " on live asa output says Active /active failover , does this means that i can only configure failover in active/active mode not in active/standby (which i want to do )?

Cisco Firewall :: 5505 ASDM 7.1 Fails To Start On MacOS

Feb 6, 2013

I have an ASA-5505 which I have been managing using ASDM from a PC and a Mac.I just happens that the Mac has not been used in a little while and when I tried to use ASDM on it, it fails.I've had a trawl through various posts and release notes (after updating various components in the process, incl Java with all the diabling/security updates of late) but am still having the problem and this is where I'm at:

- the ASA runs v8.4(2) and ASDM 7.1(1)52
- release notes state that ASDM 7.1 should work on Java 7 on Windows 7 and MacOS 10.7
- ASDM starts fine on my Windows 7 PC running Java 1.7.0_13
- I am also running Java 1.7.0_13 on MacOS 10.7.5
- on MacOS, ASDM starts, asks for credentials, download/refreshes the cached app... and then crashes with the following exception message:
 
The root cause of the issue seems to be that a Java class called apple.laf.AquaTableHeaderUI is not found..Now, I don't know much about Java, but that seems to be an Apple UI related class - I presume that it would be good to use this to give ASDM a more native look and feel, but why on earth is there no fallback? or am I missing something?

Cisco Firewall :: ASA 5520 - Verifying Flash Image Fails?

Nov 1, 2011

I have an ASA 5520, currently running version 7.25-k8. I'm preparing for an upgrade to version 7.25(4), so I transferred the software code (obtained via Cisco download) to the firewall vis SCP. I then issued the "verify flash:asa725-k8.bin" and it fails. It comes back with the error that the CRC did not verify, Data Integrity has been compromised". My first thought was the image did not copy correctly, so I deleted it and transferred it again. I got the same error. Then I decided to run a verify against the actual current code that was running on the firewall, and it came back with the same error. I don't understand what the problem is. I don't tend to think it's an SSH key related problem, as the method I use to access the firewall is via SSH and I have no problems. Worth noting,this firewall is part of an active/standby pair, and I observe the same behavior on the failover unit, it fails to verify.

Cisco Firewall :: ASA 5510 - FTPS Explicit Client Fails At Init TLS Stage

I have disabled the FTP inspection on the firewall and I have opened some high ports from the Internet to the test workstation (ACL and NAT rules), but without results.
 
If I try to connect from a workstation to the FTP server using a direct Internet connection I can access the FTP server without problems, so I think the problem is in the ASA.
