Cisco Firewall :: 8.0 To 8.2 Upgrade Would It Affect Configuration 5550
Apr 29, 2012
I am planning the upgrade of an ASA 5550 Active/Passive cluster from 8.0 to 8.2 according to the "zero downtime upgrade" documentation available in the web.
I do not have another cluster for comprehensive testing, but I executed a simple migration procedure on a tiny 5505 and neither licensing features nor the configuration (the command sintax) were affected by this process. I know this is something to care about if you go to 8.3, but this is not my case.I browsed the release notes of 8.2(5) and no special disclaimer was found by me with respect to this release. So everything should work just fine, but I would like to double check for input with respect to these two subjects:
1.Will the licensed features (vpn, concurrent connections, etc) be preserved?
2. Will the configuration be preserved ?

I have a couple of ASA5520 and ASA5550, and I wanted to know if it is worth it to upgrade the software from 8.2(4) to 8.2(5)? Because of the RAM I cannot upgrade to 8.3 for now.

Since the "zero-downtime upgrade" is not supported, I would like to validate the process I put together for upgrading a failover pair of asa5550 with the characteristics below. Specifically I am concerned with the role of the standby during the upgrade. This is my setup:
.- single context mode
.- active/standby
.- current firmware asa821-k8.bin / asdm-621.bin
.- role: firewall and VPN concentrator for segmented server farm network. Dynamic/static/exemption NAT heavily used.
My target is asa842-k8.bin / asdm-645.bin and I am doing a two step upgrade (8.2(1) -> 8.3(1) -> 8.4(2)) to avoid the "unidirectional" attribute and CSCtf89372 bug issues. This is a short version of what I have in mind:
.- Verify stability of failover pair and make adequate backups before beginning.
.- plug into the console of active, ssh into active and standby.
.- vpn/act(config)# no failover ( disable failover from active )
[Code]....
After reboot, point to 8.4(2) and reload again. Same concern regarding the standby unit.
I understand there might be configuration tweaks needed to the NAT configuration. After second reboot test connectivity and if successful, on active "failover", "write standby" and "failover reload-standby". Otherwise "downgrade" and back to the drawing board.

I am in the process of adding a new ASA 5550 as a standby box to an existing ASA 5550 running on transparent mode. Both are on version ASA 8.0(4) and ASDM 6.2(1). I have set the new ASA 5550 to transparent mode. The configurations are the following for the HA: [code]My questions are the following:
1. The management ip address is different than the ip used for the failover link. Since the firewalls are on transparent mode, does the failover ip needs to be the same as the management ip address?
2. Does any other additional config is needed for HA to work for basic active/stand-by failover?
3. Which is the best method to add the second box without disrupting the active box?

I have pair of ASA 5550 and I am trying to copy a new config to my member1 (active) as the new configuration I want to use for the pair. I want to copy this to start-up config on member1 and then reload member1 and have it copy the same config to member2 (stdby). I guess I am trying to understand if I copy the configuration to member1 and reload it, member 2(stdby) will have become active and try to copy the old configuration to member1 which I do not want.
get the commands straight that I need to execute to make sure the new startup config gets to both members without being overwritten?

I'm planning to upgrade Cisco ASA 8.2 to an anyconnect essentials and mobile license. Are there any concerns with some users continuing to utilize the cisco vpn IPSEC client while others migrate to the Anyconnect? I just want to make sure when I upgrade the license that there will not be an immediate requirment to have all users switch to Anyconnect immediately.

Im running 8.3 on a 5505. We've got a few ssh tunnels originating from inside to some place on the internet. It seems these tunnels are closed every n minutes. I've seen two recommendations for altering the timeout values, and what I am interested in is infinite timeout (0) for these SSH tunnels.
Suggestion 1, alter timeout "conn". Default is 30 minutes, but I suspect this might have a negative impact because no inactive connections would be closed, ever. If it however is recommended to alter, how to set it to "0" (off/unlimited)? timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02
Suggestion 2, enable a ssh class map which explicitely set the timeout for the ssh connection. Is this recommended? How would I achieve unlimited time? And what about random-sequence-number disabled as seen below, is that really recommended?
class CLASS_MAP_SSH
set connection random-sequence-number disable
set connection timeout idle 48:00:00 reset
set connection decrement-ttl

I am forced to upgrade my ASA 5520 software from 7.1 - 8.2 or higher, as I am not familiar with ASA I need expert opinions.I have following concerns regarding the upgrade.
1-Do I need to worry about the software licensing when I download 8.2
2-I read about the few difference in commands (ACL and NAT) in 8.2 what exactly I have to do here should I change the configured NAT and ACL with real IP in the existing configuration after the upgrade ?

i two 5550 firewall set up for redundance purpose . in failover we define two different ip add one for primary and one for secondary .interface Ethernet0/0 nameif outside security-level 0 ip address xxxx.0.0.0.1 255.255.255.0 standby xxxx.0.0.2!interface Ethernet1/0 nameif inside security-level 100 ip address 10.0.0.12 255.255.255.0 standby 10.0.0.11.default gateway for host will be 10.0.0.12 (primary fw address) however in case of failover , the secondary fw will be up with ip address that was assigned for primary .in this case the secondary ip add 10.0.0.11 is actually nerver used? similarly do i need to have two public ip address for outside (one for primary and one for secondary ) ? or in case if primary fails the secondary comes onlie and take the ip of primary fw . hence i only need to purchase just one ip address.

we had just installed our ASA 5550 with IOS 8.0(2) a couple of week ago.
2 interfaces from each slot are being used ie 0/0 for Branch users comming via MPLS cloud , 0/1 for internal LAN users comming form Core Switch & 1/0 for Server farm LAN , 1/1 for Internet (outside)
the first 3 interface are considered inside with sec set at 100 while the 1/1 is outside with sec at 0.
Last night it suddenly started dropping all connections without any warning or any noticible log form the ASDM logging.
the connection drop would happen for 2 - 3 minutes and would work fine for the next 15 minutes or so..
after conencting the console , we found out that the IOS would suddelny go abrupt and show this display ...
TP-ASA(config)# TP-ASA(config)# TP-ASA(config)# Thread Name: Dispatch UnitPage fault: Address not mapped vector 0x0000000e edi 0x24d184b0 esi 0x0000000d ebp 0x1c6ceaf8 esp 0x1c6ceae0 ebx 0x09e965e0 edx

I have looked in the books I have (Cisco ASA, PIX and FWSM; ASA 8.0) and googled a good bit but can't seem to find any specific mention of how to do NAT exemption with v8.4. It seems NAT exemption (NAT 0 access-list) was deprecated. Using ASDM, there's no corresponding menu item for this that is obvious.
We have public addresses inside the ASA and want to allow in/outbound connections using these IP's without NAT. The ASA is a 5550.

I need to understand if ASA 5550 ver 8.2(1) is comptible with IPv6, if not what is the upgrade path to make it IPv6 compatible. The requirement is dual stack of IPv4 and IPv6 should run in the same HA cluster and later will shift IPv6 completely.
The existing infrastructure is equipped with ASA with HA Active/Active mode. The command output for required details are attached here in txt mode.

I have Active Standby ASA5550 setup with VPN premium license. A few days back we had a requirement of SSL VPN connection for and we got a temporary from Cisco for same, this license expired and the ASA reverted to it's original license. 3 4 days after this we saw a sudden increase in CPU utilization (upto 90% + -5%) on the ASA during production hours but were not able to figure out the reason, in order to restore the services we failovered the firewall to secondary and everything worked fine. We were suspecting one of the following but there were no logs for any of this
1. The ASA hardware was haivng problem
2. Some client was doing a DoS attack to bring down the ASA (no logs for this as well).
We took a downtime to look further by failovering the ASA back to primary and it worked fine without any issues ruling out the 1st option. We also came across a licesing doc [URL]
Downgrading any license (for example, going from 10 contexts to 2 contexts).
# Note If a temporary license expires, and the permanent license is a downgrade, then you do not need to immediately reload the security appliance; the next time you reload, the permanent license is restored.
As per this doc, sooner or later a restart was required on the ASA. We restarted secondary ASA and everthing was fine but when we restarted the primary ASA by swtiching over to secondary some of the server (not all) in the DMZ stopped working (even ICMP unreachable) and only came back to normal when the primary ASA was restored and working fine (with failover).
The reboot was done by shuting down the physical link between the Core switch and ASA inside individually.
I am not sure what could be the issue that the servers in the DMZ wen unreachable.

In my Cisco ASA 5550, I need to set two different syslogs servers, and I need to send the system logs to the first one (only admins login/logout), and the traffic logs and all the rest (informational level) to the second one. Do you know if is it possible or not and, if yes, how to configure it?

I am using an ASA5550 for a complex secure network that has at least six "outside" networks. Each "outside" network is assigned to a specific port each set at level "0". I also have a DMZ, set to level "50". I am having difficulty with passing traffic from a host in the DMZ to all but one of the "outside" networks. Is there a limit to the number of "outside" interfaces? I will provide a redacted config file as soon as possible.

I have the following problem, right now we have an ASA 5550 connected to the client´s side. A reset is being received on the client´s side, but when we run the sniffers on both extremes of the network, we can see that the reset is not being sent by the server´s side.
We have narrowed it down to the 5550 ASA, but have found no bug that matches the description.
The characateristics of the reset packet are the following:
- It is the only packet with a TTL of 255.
- Both server and client have very different window sizes, and the reset packet even though has the server´s ip and port as source of the packet, it has the client´s window size.
- It has a correct ack number.
-Before the reset is received, there are a couple of retransmissions of the last packet sent.
- We´re handling a VPN tunnel between both servers.

I cannot logon with adsm anymore.when I run adsm, I type in my pw, and the screen keeps displaying "contacting the device". No timeout, just stays this way.I've updated the java version, no luck.I can connect with SSH with no problem. device = asa5550, 8.2(1) asdm 6.2(1) [code]
notice that there is no "with cookie-based authentication" here -- is this relevant?
Rebooting the device is not really an option.
