Cisco Firewall :: 5550 - Apply New Startup Configuration To ASA Active Member?
Jun 17, 2012
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 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 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.

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.

with 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 have two ASA 5510s running in Active/Active mode. I need to make config changes on them. How do I go about it? Do I power off the secondary ASA and make the config changes on the primary and then power on the secondary ASA ? Or this another way to do this?

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

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 2 ASA 5505 running 8.3(1) and ASDM 6.3(1).
the first unit is currently working, and i now wish to configure the second unit as standby. im configuring through the ASDM GUI. Started the HA Wizard, choose Active/Standby configuration and enter the IP of the peer device. checks come back all ok. On the LAN link configuration page (step 3of6) Interface is pre selected as VLAN99, I give it a logical name as iface_fail, and enter 10.0.0.1 as primary address and 10.0.0.2 as standby, subnet as 255.255.255.248, and select port Ethernet0/5
Note that if i click on the buttons next to the IP fields, i get IP addresses of remote hosts!.

I currently have a LAN-based failover setup between two 5510s. The failover link is a crossover cable. In the current setup, if I unplug the crossover cable both units become active. From what I understood from Cisco documentation, each unit should mark the failover interface as down and there shouldn't be any failover. That's exactly how I want this setup to work.

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 have been having an annoying issue for the past few weeks with my ASA setup. We are using the ASA as our Remote Access Gateway and originally had it setup in a Active/Standby failover configuration using 2 x 5520 ASA's.The original setup of the devices was that the 2 x ASA were setup in a failover configuration, with both of them connecting back to the internal network via a 6500 device. Because of using failover I created a VLAN on the 6500 and put the two ports that connect the ASA's into that VLAN. I then configured the VLAN interface to be the EIGRP interface for the neighbour relationship to the ASA's.
The problem I am seeing is that the EIGRP neighbour relationship between the Active ASA and the 6500 keeps flapping. It occurs abour 4-5 times every day at randmon intervals. Sometimes the neighbour relationship will stay up for 6-7 hours, other times it flaps every 1-2 hours. I initially thought it was due to the failover configuration so I removed one of the ASA's and removed all of the failover configuration, but the EIGRP neighbour flapping problem still exisits. [code] Since removing the failvoer configuration I am thinking it could be a physical cable problem?

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 a pair of ASA 5520s operating in failover pair as active/standby, having two contexts on them. I am planning to share the load and make it active/active making first context active on the primary unit and second context active on the secondary unit. My question is if this will disrupt any connectivity thru these firewalls when I do "no failover" on the active/standby and assign the contexts to different failover groups and enable the failover back.

I want to implement Active/Standby cluster with a pair of 5550 ASAs and I have a licensing question. Here is the "sh activation-key detail" output from both devices...
ASA1:
sh activation-key detail:
Serial Number: XXXXX
No active temporary key.
Running Activation Key: XXXXX XXXXX XXXXX XXXXX XXXXX
[code]....
This platform has an ASA 5550 VPN Premium license.The flash activation key is the SAME as the running key.So it looks obvious that I'll have to upgrade the first ASA to support 25 SSL VPN Peers in order to build HA cluster, right?Now I want to know do I need the "ASA5505-SSL25-K9" license or something else.

don't have an option to connect a console cable to my cisco router. The usb to serial converter will not work in windows7 only on XP.have physical access to my 881 Cisco Router. If I remember correctly these routers have a default ip address. This router is brand new, out of the box. I am thinking I can access it with the correct IP via network instead of console.

I have a Cisco 850 router that whas having problems getting an ip address via DHCP. I did some stuff on it but that didn't work, so I rebooted the router to go back to my last saved startup config. When I turned it back on and connected t othe CLI console I got the "Would you like to enter the initial configuration dialogue?" message. Thinikng I just forgot to save anything to the startup config I went through the initial set up again and made sure to save everything to the startup config. After going through the intial config and setting up a vlan to assign DHCP to clients I saved the config and rebooted, upon reboot and connecting to the CLI console I got the same "Would you like to enter the initial configuration dialogue?" message. Tryign the setup once more and making sure everything was saved to startup config I rebooted again just to make sure the changes would stick, and sure enough they didn't. Whay is the config not saving to the startup config?

I'm running LMS3.2 and RME 4.3.1. I deployed a netconfig job to our network which consisted of approximately 800 devices.The report said that the job completed successfully however some of the devices didn't save thier running config to startup.
Is it possible to add a command or issue another netconfig job just to save the running config, so I can identify if the job fails on some devices? Using the tick box in the netconfig job doesn't seem to alert you if its not successful.

I was working on a Cisco 2600 series router earlier today running IOS 12.4. I ran into an issue where I could not clear the startup-config. I tried:
router#erase startup-config
router#reload
router#erase nvram
router#reload
[code]....
each time IP addresses and things got cleared but other aspects did not which should have been. In the nvram there were several files:
Router#dir
Directory of nvram:/
126 -rw- 2143 <no date> startup-config
127 ---- 5 <no date> private-config
128 -rw- 2143 <no date> underlying-config
1 ---- 49 <no date> persistent-data
2 -rw- 0 <no date> ifIndex-table

There are two issues which are testing my resolve.
1) Bad Cryptochecksum Ignored error
2) Unable to boot to a save startup-config file.
I want to take the configuration from one ASA 5505 and move it to another ASA 5505. I copied the startup-config file from an ASA 5505 running asa821-k8.bin to an ASA running 8.222-k8 to flash using tftp. I set the boot config parameter on the new asa to flash:/startup-config which is the location of the startup file. If I use copy run start command, I over write the startup file. When I copy the startup configuration to the running configuration I get a Bad Cryptochecksum Ignored error and the startup file does not copy over to the running file. How can I resolve this issue?

I messed up the IOS on the flash of CISCO881-SEC-K9. On reboot it booted to ROMMON which allowed me to tftp up a working IOS c880data-universalk9-mz.151-4.M3.bin. Unfortunately somewhere in my playing around the default startup configuration factory loaded on the routerhas been erased. I can load a new a config on the device but as I'm using the router to learn its useful to have the original config load when I factory reset the device. What is the factory start up config?

I have reconfigured the FEX numbers attached to a Nexus 5548 running on NXOS5.2 If I do show running-config the interfaces are not there anymore. But if I do show startup-config the old Fex interfaces still shows up. I did try write erase then saved the running-config and its still there.

I 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?

I will be implementing a new firewall (cisco asa 5515x) on my existing 3750x (server switches) and my 2960s (user switches). What should I need to apply on my firewall and swtiches to make the implementation successfull. I will put my 3750x as my DMZ and my 2960s as my inside. The 3750x have multiple subnet and also the 2960s.which features and technologies i need to know on those 3 products. my 3750x and 2960s don't have any ACL defined and most common features are vlan, switchport, trunking, spanning-tree, stacking, vtp.how my asa knows that my 3750x/2960s have multiple vlans. my current connection right now on 3750x and 2960s is just through 6 ports i assigned as one trunk, below is my config [code]
my 2960s vlans are almost the same with my 3750x except vlan 160, 170, 192. but of course when i put this in asa, i have to segragate vlan for 3750x (192, 100, 110,160, 170) and 2960s (130, 150). for my 2960s connection to the asa and since this will have big bandwidth, i will use 3 ports on my asa (and trunk it) connecting to my 2960s and i will use 2 ports on my asa (and trunk it) connecting to my 3750x. the one internet ports and my one management ports on my asa will stay like that.

I 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..

I was wondering if I can force catalyst 2960 to skip startup config stored in NVRAM and boot with no config everytime it is powered. I tried to find it on google and in cisco white papers but still no luck. I found only commands that begin with "set boot config-register ... ", but switch acts like it does not know these commands.

I have an 877W router that I would like to have a 2nd pre-configured backup for. I was thinking of getting another 870 series (probably an 877) router, as the more expensive wireless option is not actually required. Am I right to assume that I could simply copy the contents of my current config.txt file onto the second router?

we have a nat exemption rule for 10.0.0.0/8 to w.x.y.z followed by some static nat rules and then dynamic policy nat rule for 10.0.0.0/8 to w.x.y.z natting to IP a.b.c.d.When I do a packet trace from 10.10.10.10 to w.x.y.z, it shows the packet first matching against the nat exemption rule, and then immediately afterwards it matches the dynamic policy NAT rule. The static nat rules are being successfully bypassed (which is what I want), but why does the dynamic policy nat rule apply if an exempt rule has been hit already? An actual test between the IPs above reflects the result of the packet tracer as well (IP a.b.c.d is seen on server w.x.y.z).We are running the following software on an ASA5520.
