I am having a curious problem with two Cisco ASA 5550. They are configured in Active/Standby failover and in routed mode.The problem is: I cannot connect via SSH to the ACTIVE unit, only to the STANDBY. If a switchover is forced the problem is still the same. because it happens both with the primary and the secondary unit.It is not a L2 or a transport problem, because I can ping or access both units via ASDM.
View 8 RepliesI am looking at deploying a pair of 5585X's in an active/active multiple context state. I am creating Mulitple contexts that need to be able to route to each other. I was going to deploy a type of Gateway context that has a shared interface to all of the other contexts, instead of sharing interfaces directly between the contexts, i beleive this will work as basically i am just cascadng the contexts and sharing interfaces.
The main problem i have come across, is that if i deploy active/active across two appliances using 2 failover groups i can not see a way to route between them, for example.
I have Context 1, Context 2 and Context GW A including the shared interfaces of Con1 and Con2 in failover group 1 on appliance A with the respective standbys on Appliance 2. I have Context 2, Context 4 and Context GW B including the shared interfaces of Con 3 and Con 4 in failover group 2 on appliance B with the respective standbys on Appliance 1.
I need to be able to route traffic between Context GW A and GW B so that the contexts can communicate in normal operation and in failover. I do not beleive that I can share an interface between contexts in two separate failover groups and to be honest without adding a L3 device between the appliances i am not sure if this is possible.
I have an ASA5520 in location A with an ISP connection and a matching ASA5520 in location B with a separate ISP connection. We have fiber connecting the two locations and vlans passing back and forth so I will be able to configure the failover via a vlan as well as extend the ISP's to each location via vlans. The Active/Active configuration with the multiple security contexts does not seem to be an issue but how is a redundant ISP configured in this mode?We want to have context A using the ASA in location A with ISP1 as the primary and failing over to ISP 2 in locaiton B We also want to have context B using the ASA in location B with ISP 2 as the primary and failing over to ISP1 in location A Would route tracking provide the desired result? Is there a better option?
View 1 Replies View RelatedI have 2 asa 5520 firewalls including and 1 AIP-SSM-10 module in each of them. the configuration is set using active/active failover and context mode.
Both of them run individualy the IPS module. The IPS is configured using inline mode and fail-open option. However when one of the module fails and the state is changing from up to init or anything else making the IPS to fail then failover is detected and ASA consider it as failover and bounce context to the other unit.
IPS soft is 6.0(4) and ASA soft is 8.0(3)
I have checked cisco doc and it is confusing to me. it says: "The AIP-SSM does not participate in stateful failover if stateful failover is configured on the ASA failover pair." but it really does participate. Running is not really an option because of production network impact matter..
its possible to set up active/active failover using etherchannel on 5585s?
View 1 Replies View RelatedI would like to work with two ASA's 5550 in HA (Acitve-Standby) like perimetral firewalls and also work with another ASA 5540 but like a SSL VPN Remote Access to end users.Which will be the best topology to this scenary?. Perhaps i need to put the ASA 5540 SSL VPN together with the ASA's in HA directly in a port.
View 1 Replies View Relatedwith the 5550 we get 4 gig ports on slot 0 and 8 gig ports on slot 1, also a fast Ethernet management interface port. The documentation states that only 8 ports can be active at any one time but does that exclude this management port so that I can use this as well ?
Also is the port assignments for slot 1 like g1/0 - 1/7 ? As the other the 8 ports in slot 1 are 4 x gig E and 4 x gig sfp.
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
View 2 Replies View RelatedAccording to Cisco, one of the ASAs must have an Unrestricted License [URL]:
"On the PIX/ASA Security appliance platform, at least one of the units must have an unrestricted (UR) license. The other unit can have a Failover Only Active-Active (FO_AA) license, or another UR license. Units with a Restricted license cannot be used for failover, and two units with FO_AA licenses cannot be used together as a failover pair."I am unfamiliar with the different ASA licenses, so with my current license, I am unable to enable failover on my two ASAs. Here is a snippet of the "show version" output on one of my ASAs (they are the same as far as licenses go):

I am trying think of a better way to provide redundancy on some internally protected networks. We maintain our own WAN/backbone between our primary site and backup site. Is it possible to have two Cisco ASA 5550s in setup for failover at completely different sites as long the networks connected are available?
View 3 Replies View RelatedI 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've two Cisco ASA 5550 firewall. I'm don't have much knowlege on configuring this kind of firewall. I need configuring these firewall for simple NAT. I have 3 public IP address. I would like to allow server's inside of the firewall to be able to connect to internet using private address. A basic NAT. Also need to configure some port forwarding. We've bought two firewall for the Active/Active failover support. How can i configure this through ASDM? My ASDM version is 5.2.
View 1 Replies View RelatedSince 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 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 have encountered a problem in one of customer that the Active ASA 5580 is unable to sync with Standby Failover ASA. When Active is connected with FO and push the configs to it will not find the ethernet/Gig interfaces due to which the all the configuration were not applied and when the primary ASA the secondary is unable to respond.
When i attached console with the Standby ASA i have seen this error.
Number of interfaces on Active and Standby are not consistent.If the problem persists, you should disable and re-enable failover on the Standby.
For detail undestanding i am attaching the configs of primary and standby ASA. The KHI-DR-ASA-BB-01 is the standyby firewall.
I have a problem with failover. On My site I have 2 Firewalls 5580. And I did this configuration on my firewall.interface GigabitEthernet3/0description LAN/STATE Failover Interfacespeed nonegotiate.
View 5 Replies View Relatedi 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?

View 2 Replies View RelatedI have just finished setting up two ASA5510s in Active/Standby Staeful failover, using the Management interface for both failover and state. Everything appears to be working well.Configurations were transferred and the "sh failover" on both accurately reports their status before and after a failing the active device.I monitored the inside IP with a continuous ping (using a Windows client) and noticed that there were usually two to three ping responses lost. Is this normal?
View 1 Replies View RelatedWhat 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.
View 2 Replies View RelatedI currently have two 5540's in an Active/Standby pair. The primary unit failed on February 12th, so the secondary ASA is now the active one. My question is this - we have made a lot of changes since February 12th and I am planning on fixing this failover issue over the weekend. Will the secondary (now active) FW sync it's config to the non-active FW, or will the failed FW sync it's out-of-date config - removing any changes that we've made in the last month or so.
View 1 Replies View RelatedI 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.

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 2 ASA 5540s ver 8.3 in Active/Standby state.I am considering a future hypothetical situation where I might need to rename interfaces or reallocate redundant interface groups. Doing so obviously has a major impact on the current primary configuration. My goal would be to minimize or eliminate network downtime during the interface changes.
I am wondering if it is possible to force the secondary ASA from the standby to active state.Then temporarily disable failover on the primary unit.Make the interface changes on the primary unit Then reactivate failover on the primary unit Force the primary unit back to active and secondary unit to standby My new interface configuration would then sync from the primary to the secondary.
I believe this would work but must ensure that the secondary ASA can function as the active unit while the failover is disabled on the primary unit. Is there a set length of time the secondary unit can remain active without a failover peer?
see issues with operating the secondary unit in this manner while making changes to the primary unit?
I just added a new 5510 failover unit to an existing 5510 and when connecting my new outside interface on an Active/Standby firewall pair, i get errors messages (red x) on each port scan (monitor & syslog) although the error message indicate all ports are good...additionally the firewalls flip between active and standby non stop. I remove the new standby unit outside interface from a shared switch and everything clears up.

View 4 Replies View RelatedI am setting up a new pair of ASA 5585's in a multi-context, active/active failover design. I cannot create management SSH connection to the contexts that are assigned to failover group 2. With all the security contexts that are assigned to failover group 1 I can SSH to the inside interface IP and login without a problem. When I try to do that to the group 2 contexts there is no response from the firewall at all, PuTTY just times out.
My firewalls are running version 8.2(4). The contexts seem to be functioning normally in all other respects.
I am trying to setup an active/standby failover with 5520's running 8.4(2) and am having problems with it not dropping connections during the failover. I am using a portchannel from the switch to each ASA and using sub-interfaces off that. I'm using the command Failover mac address Port-Channel1 “mac-address on primary Port-Channel1” “mac-address on standby Port-Channel1”.The command goes through but doing a show interface port-channel1 doesn't show a change in the mac address on the secondary unit after a failover when it becomes active.
View 3 Replies View RelatedI have two ASA in failover with Active/standby configuration. When I switch from standby to active from the standby ASA I get a lot (like 100) of error messages like these below: [code] The failover works fine and nothing seems to be wrong with the firewalls function.
-Hardware is ASA5585-SSP-10.
-Software version: ASA 8.2(5),
ASA is in multiple mode with 17 active context. Why these error messages appear and what they mean?
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.
