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?
I am adding a failover asa to an a firewall that is already in production. They are both 5510's, they both have the same abount of ram, have the same code versions. Will there be any downtime while adding the secondary in?
We have 2 ASA 5510's setup in an active, standby failover configuration. When the primary fails over to standby, the 3rd party cert does not failover to the standby ASA. The users then receive the CERT missing, invalid message and have to select yes, no to move on. This does not occur when the primary is not in failover mode. It is my understanding that failover fails over certs but in our case it does not apper to be working correctly.
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.
We have a customer who has a network consisting of two ISPs, one as a primary and the other as a backup. We are trying to create a configuration that would allow the primary link to fail and the secondary link to automatically pick up traffic and begin routing .how to set something like this up. Both routers are non Cisco routers and there for HSRP is out.
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.
I have 1 2611xm router and 1 2801 router. For my own lab purpose, i want to configure them back to back to support voice services. I don't know what configuration will be required at each end. in 2611xm, i have NM-2V and its also detecting the card, so i hope it will work ? also what commands i need to run on both ends .
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?
I downloaded a new image to my ASA 5510 and found out up on reboot that the ASA doesn't have enough memory so I am booting to the "ciscoasa" prompt with no config. I still have my old image in disk0:. How do I roll back to this old image?
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 setting up a network that will use the 1941 router with a cellular card (HWIC) to connect to the Internet for communication with remote stations in the field. The 1941 has a static IP address (166.142.xxx.yyy) on the Internet provided by the ISP (Verizon). The 1941 is connected via ethernet to the ASA5510. The end goal is to have the field cell routers (Digi Transport WR-44-R, also static IP) connect to the ASA5510 via VPN tunnels for communication back to the servers behind the firewall. I'm not sure exactly how to configure the 1941 so that the remote router can connect to the ASA using the public IP of the 1941 router. I have the 1941 working stand alone and can connect to the Internet and pass traffic, but I tried a static NAT to translate the public IP to the private IP of the ASA and cannot pass traffic. below is part of the 1941 configuration: [code]
Do I need to use VLAN bridging to accomplish the task or am I missing something with the NAT?
I have an ASA 5510, one public IP address on my outside interface, an internal email server and a private network.I would like...
1: Users on my private network to be able to access the internet (PAT them to external outside address) 2: Email to be delivered to my MX (my single public IP address translated back to my internal email server.
i.e. can I share my single public IP address to serve translation in both directions (private users surfing the Internet (in-to-out) and an outside to inside NAT for email) ?
Email (MX) = 1.2.3.4 Public (outside) address = 1.2.3.4 Email server internal = 10.1.2.3 Internal private subnet for users = 10.0.0.0/8
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.
Cisco still doesn't provide failover (active/standby) between two different types of ASA, right?

"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"
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 ?
I have 2 PIX 525, which one of them, step and active failover mode the other PIX 525, leaving this off, do not know what happened may have been a power outage, but in any case I can turn it back on? And the other question I have is if I can import a configuration that I have saved on my computer. i have the PIX device manager.
I am pretty new to Cisco networking and setting up a test router to use from home to connect into our network. My organization would like for us to provide upper management with home office setups to give them the ability to work from home. We will provide all of the equipment of course (router, phone and workstation). my boss wants me to use some of our old decommissioned equipment to set up a test home office to see how efficient and feasible it would be. I have a Cisco 1700 router, Altigen IP720 phone, and Dell Optiplex 380 workstation.
i read that you need only one L-ASA5510-SEC-PL for setting up a Active/Standby Failover. I installed the license on the 1st ASA and tried to setup the failover via the ASDM wizard. It always fails, because the 2nd device can't have a 'base' license.So does this mean, i really need another license?
I have two ASA 5510, The one which I just got shows the CPU speed to be 1599MHz While the previous device (which is also 5510) reads the CPU as 1600 MHz.According to Cisco, for Failover redundant configuration, both devices must have same hardware configuration. Technically, this slight difference should not be an issue but I need to confirm that thess devices will work fine with failover configuration.
I have ASA 5510 connected as shown in attached diagram.Ideally when ASA 1 is active and if I boot Switch-1, ASA-2 shood take over. But that is not happening.When I boot SW1 , ASA-2 shows "Failover LAN Interface: failover Ethernet0/0 (Failed - No Switchover)" and remains standby.Fail over works properly If ASA-1 boots.
i have a couple of ASA 5510 in Active/Failover configuration. Failover LAN is configured on management0/0 e the ASA are connected with a back-to-back direct cable.
ASA has an interface in access mode inside with standby ip address and show failover is compliant with expected result in show failover (Normal)

I discover an issue with my CISCO ASA 5550 because I'm looking at the vlans that I have configured and some vlans on the Stand by device had not an IP address configured, checking the configuration of the failover
What I am attempting to do is setup snmpv3 on two failover 5510's .The problem I am running into, the snmp management software rejects one of the devices as it sees it as having a duplicate engine ID since the two devices share the same config. Would like to know how this would work in an active/active setup being able to poll both devices.
we are running two failover pairs of asa (5510, 5505) in two different locations in active/standby configurations.Is it possible to access the inside ip of the standby unit via vpn terminated by the active unit? It's only for monitoring.With our configuration here it is not.Is that possible in general?
understanding clear about new Cisco ASA 5515-x, 5525-x.I know that this device supports IPS which is included to this appliance without any additional modules.But can this box support IPS and content-filering (Cisco ASA CX or so..) in the same time.
The problem also in next. Can two ASA 5510 with diffrent modules (in one AIP-SSM and in other CSC-SSM) be in active/active failover design?
I have a single production 5510 with 2 contexts. Now I want to integrate the secondary failover unit. My question is: How much configuration needs to be done on the secondary firewall? How much of the configuration will be sync'd from the primary to the secondary when the secondary is connected?
For example, do I need to add the following on the secondary or will it be sync'd from the primary?
admin-context NAME context NAME allocate-interface Ethernet0/0.14
