Cisco VPN :: ASA 5505 - Way To Shorten VPN Failover Time?
Mar 26, 2012
I have two sites that each have asa 5505's and each have dual ISP's. Currently I'm using sla monitor to failover to the secondary line when there is a detected outage. After this sla failover occurs which seems to be instant, secondary ISP re-establishes the VPN. This process takes about 30 seconds. My thought is that the side which is healthy does not detect the outage due to a preset amount of timeouts and thats where this 30 second delay comes in to re-negotiate the VPN tunnel. can I create a smaller window of time to heartbeat between the two so that the VPN outagage is detected in around 5-10

We have ASA running code 8.0.4 with Active/Standby for quite long time. Today when we gave the command wri standby it started sync the config to standby ASA but waited forever.when we checked the show failover, we got the following result.
This host: Secondary - Active
Active time: 1928633 (sec)
slot 0: ASA5540 hw/sw rev (2.0/8.0(4)) status (Up Sys)
Interface PERIMETER-MGMT (10.12.8.1): Normal (Not-Monitored)
Interface OUTSIDE (86.36.xx.xx): Normal (Waiting)
[code].....
When we console to Standby ASA and tried to save (wri mem), we got the following error and also please note the hostname has become default...?
ciscoasa(config)# wri memory
Building configuration...
Command Ignored, Configuration in progress...
[FAILED]
and when we tried to give following command we got this error:
ciscoasa(config)# copy running-config startup-config
Source filename [running-config]?
%Error reading system:/running-config (Configuration temporarily locked)
ciscoasa(config)#
I see here the standby ASA IPS module is down, but can that issue cause not sync the config backup and writing to nvram (save config)..?

We have two sites connected by a gigaman line. Routing between the two sites is done with a couple of HP routers. We also have two separate Internet connections, one at each site, through different providers. The border firewall at one site is a Cisco 5505 and at the other site it is a Cisco 5510. If the gigaman line goes down, we would like to fail over to a site-to-site VPN. Any clue how to set this up? We can set up the site-to-site VPN. how to make it serve as a failover. Another question is whether the VPN will cause confusion when the gigaman is operational.

I have a ASA 5505 which is connected to a remote site which also has a ASA 5505 over a L2L VPN tunel. One of the sites has a WAN failover configured with two ISP which is working successfully.
But, when the WAN connection fails over to the backup connection the VPN link breaks as the peer site IP address has changed and the VPN can not establish a connection.
Would it be possible to configure a VPN failover so that when the connection failovers so will the VPN tunnel?

There are 2x Cisco ASA 5505 in an active/standby failover config. The primary asa 5505 has been reset and the secondary is now running as active. I would like to reintroduce the primary again but need to know how to do this.
Ideally I would like to remove the failover config and start from scratch. Do I just need to enter the following to disable failover on the active secondary box?
no failover
no failover lan unit secondary
no failover lan interface failover Vlan999
no failover interface ip failover 192.168.254.1 255.255.255.252 standby 192.168.254.2

So we currently have a T1 connection at our location. We were looking to add a high speed cable internet and add an ASA 5505 with Security plus license to do failover between the two. I have found a few examples on how this would work but curious about a couple things.
We would want the Cable to be the primary, T1 as a backup.Currently the IAD that handles our T1 does dhcp, dns, and NAT.. Who/what would handle these items with the setup above?

I’m working with a customer who has upgraded from a Sonicwall w/ PCMCIA card slot to a Cisco ASA 5505. They were using this slot with a Verizon card as an ISP failover. Obviously the ASA does not have a PCMCIA slot to reuse this aircard. However, I was wondering if there is another solution to use the existing aricard with the ASA.

I have a question regarding failover monitoring on the ASA5505 in an active/standby configuration.
I understand that on the 5505 you create VLAN interfaces and then assign the VLANs to the 5505 switchports. With failover configured on the 5505, the VLAN interface names are monitored. For example, VLAN 100 interface named Inside is assigned to ethernet0/1, switchport mode access. When issuing a show failover command the output will show the monitor status of interface Inside..
Does failover monitor the VLAN virtual interface only? Does failover also monitor the link status of the ethernet0/1 switchport?

I'm looking for automating a couple failover scenarios. Both VPN redundancy and black hole internet traffic redundancy.I currently use the more reliable T1 connection for the VPN connection and the DSL for internet traffic.My current configuration is working but requires a manual update to get the VPN or black hole back up and operational when either link fails.

I need my ASA 5505 to support ESP-AES-128-SHA on 2 dynamic clients, one with PFS and another without PFS. I add 2 dynamic maps like this. [code] Now the client without PFS can be connected, but the one with PFS cannot.How can I set the dynamic maps so that they can support both clients at the same time?

I currently have a problem where I have to constantly reboot my ASA whenever my cable modem reboots. The ISP (Pen Tele Data) is setup so that my ASA has to obtain its' static IP using dhcp (ip address dhcp setroute) on the outside interface. Now, I also have another location with a cable connection (Comcast) that does NOT experience the same problem. However, the difference is this ISP allows me to assign my static IP directly on my outside interface. What can I do so that I don't have to reboot my first ASA everytime modem reboots.

I have a Cisco ASA 5505 in our office. We are currently using Interface 0 for outside and 1 for inside. We only have 1 Vlan in our environment. We have two three switches behind the firewall. Today the uplink to Interface 1, to the firewall, on the switch went bad. I want to setup a second inside interface on the firewall and configure it as failover incase this happens again. I want to attach it to the other switch. Can I do this? If so, what do I need to do? would it only be a passive/standby interface?

I want to be able to gather some time metrics based on source IP, and destination port. Is it possiable to track how much time a user spends using a service based on it's port number. I have figured out how to capture all the data, and I can then look at timestamps, but I would like a better way if possible. Can this be done at the firewall, or do I need a different appliance?

I just bought a WAP321 Wireless AP. I wonder why it cannot sync with our time server automatically. Every time I reboot it, the system time become "Fri Dec 31 1999 12:00:00 UCT". I have to do the sync manually by clicking on the "Save" button under the menu Administration > Time Setting.

I recently purchased a X2000 ADSL modem/router combination. For some reason the current time will not stay set to the time zone. Rebooting clears the discrepancy for a short time before it drops an hour exactly. I'm in the central time zone and the setting are correct on the basic setup.?

Is the WAG320N iPv6 compatable ? ,or could it be with a firmware update ?.Is the X2000 in the same boat in iPv6 terms as th WAG320N ?.Is there a way of retrieving "UPTIME" / "DSL connection time" information from the WAG320N and also line attenuation stats etc.Wouldn't need the above but poor isp needs keeping an eye on.

AI have a Dir-825 router. The 5GHz is turned off and the wirless is on G/N. I have shawcable for my isp and my firmware is 2.06 and its a Rev B Router. I also have Qos Engine on for allowing me to have 2 xboxes on Open NAT.problem is my wireless signal for some wired reason is VERY weak. A while ago it used to work really far way outside. It was around 150ft distance at 4 bars. Now for some reason I can't even go upstairs without getting a 1 or 2 bar signal.

Does anyone know if it's possible to use a single interface on the ASA for both the failover interface and for stateful failover? Here's my situation.I'm looking to provision a pair of ASAs and I want to do stateful failover.The problem is that I need four interfaces (inside, outside, and two physical DMZ interfaces).I'm looking at either the 5520s or 5540s and these boxes need to run the IDS SSMs, so I can't use the 4-port expansion SSM.
I want to do stateful failover so I need two failover interfaces.What I'm wondering is if I can take one physical interface,run two subinterfaces on it, and then use those two subinterfaces for my failover and stateful failover interfaces.That would leave me with the four interfaces that I need for everything else

The active RP of ASR 1006 router automatically switched over to standby while the standby assumed the active role.Not sure the exact reason for this behaviour. The image version is 122-33.XNB1. We noticed an outage when the switchover happened but the device did not crash.
%CMANRP-6-CMHASTATUS: RP switchover, received fastpath becoming active event%CMANRP-6-CMHASTATUS: RP switchover, received chassis event to become active%REDUNDANCY-3-SWITCHOVER: RP switchover (PEER_NOT_PRESENT)%REDUNDANCY-3-SWITCHOVER: RP switchover (PEER_DOWN)%REDUNDANCY-3-SWITCHOVER: RP switchover (PEER_REDUNDANCY_STATE_CHANGE)%PLATFORM-6-HASTATUS: RP switchover, sent message became active.

The network clock has changed to freerun%CMANRP-6-CMHASTATUS: RP switchover, received chassis event became active%PLATFORM-6-HASTATUS_DETAIL: RP switchover, received chassis event became active. Switch to primary (count 3)
In the output of "show redundancy switchover history" the switchover reason given is active unit failed.But currently the RPs are working as active and standby hot.

Ongoing problem I have been having regarding a l2l VPN connection between our ASA 5510 and a client's ASA 5505. The client's main ISP is Comcast and he uses a secondary AT&T internet connection as a failover. When Comcast goes down, AT&T comes up and everything works great...except for the VPN to our ASA5510. I have not been able to get the VPN connection to work on the failover network. I have set up a separate, "Backup_WAN", interface in the firewall for AT&T. All of the same rules are in place for AT&T as there are for the primary Comcast connection (the VPN for Comcast works just fine) but I still cannot get the VPN to work with the failover.
Why the VPN would not be working?

We are trying to make a VPN failover over two ASA's. However the 2 ASA's have different version and our smartnet have already expired. I was wondering if this VPN failover would work even if they are different? Or should I get a smartnet first to be able to download an updated ios?
