Cisco Firewall :: Cannot Run ASDM After Failover Asa 5520

Nov 24, 2011

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 Firewall :: ASA 5520 / Login Through ASDM?

Jun 22, 2011

I have an ASA Firewall 5520 and to add or edit configuration, I use the ASDM interface.  For some reason, the admin password that I use is no longer working.  The last time I logged on to the firewall was last week and I am the only person with access to it.  I used a backup account to login and was able to, but on the menu bar the "Configuration" button is missing.

Cisco Firewall :: ASA 5520 - Add Rules Through CMD Prompt As Against ASDM

May 28, 2013

We have a pair of ASA  running 8.0 (old) version.  The way we create outbound rules is done through ASDM and when we need to open outbound connections to a server in the internet, we create named object with IP address configured manually.But practically , this doesnt work, since  the server is a server name which can resolve to multiple addresses. Everytime the server chagnes its IP the ASA rule needs to be updated.Is there a difference if we add rules through CMD prompt as against ASDM where we need to enter IP addresses?

Cisco Firewall :: 5520 ASDM 6.4 And ASA Not Showing Logs

Feb 27, 2011

We’ve got lot of ASA appliances (around 30, 5505/5510/5520) and we never had this problem since the use of the new image software ASA 8.4(1) and ASDM 6.4(1). So, my problem is located on two ASA 5520 with active/passive failover with ASA image 8.4(1) and ASDM image 6.4(1).
 
My problem is that our appliance doesn’t show any logs when an ACL deny a packet, even if when I specify a specific “deny ACL” with a specific logging condition, asdm and ssh buffer logging are empty but the counters of the ACL increment.

Cisco Firewall :: ASA 5520 Failover With SLA?

Jul 19, 2011

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?

Cisco Firewall :: 5520 - Error Message When Trying To Access ASA (8.0(3)) With Asdm

Aug 26, 2012

When trying to access the asa (8.0(3)) with asdm the console send follwing error message:
 
vPif_isVpifNumValid: pifNum out of range!
vPif_getVpif: bad vPifNum(0xa6) from 87EBC81 from 83833B4
 
Have a strong suspicion that it is a hardware failure (since asdm has worked and have tried to restart the box) can not see any errors with any show commands, but could it be a RAM error .

Cisco Firewall :: ASA 5520 Failover Did Not Work?

Apr 17, 2011

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 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:

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?

Cisco Firewall :: Activation Key For ASA 5520 Failover Pair

Mar 20, 2012

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.

Cisco Firewall :: 5520 - ASA Phone Proxy After Failover?

Dec 3, 2012

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?

Cisco Firewall :: Rebuild ASA 5520 Failover Unit

May 12, 2011

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

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.
