Cisco Firewall :: Migrate To Multiple Context Mode On ASA 5520s Cluster?
Jun 4, 2012
I have a pair of ASA 5520s in active/standby failover mode, single context. I'll be migrating to multiple context mode later this week. Do I need to break failover first? Or if I don't need to, should I? Or can I do this while maintaining failover? Can either of these scenarios will work (or fail). I'll be remote, doing my work via SSH, but have somebody local who can console in if needed.
Migration option #1
Log into active/primary ASA
Configure Multiple Context mode
Reboot both devices
Login to active/primary ASA

I have a Failover pair of ASA5550's running ASDM 6.2(5) and ASA 8.2(2). Originally they were setup with 2 context's and an admin context but one of the contexts has now been removed. I would like to now migrate to single mode before I go about patching them to the latest software.

I have two ASA 5510 in an Active/Active failover configuration; On the first ASA I have a license for five security contexts, on the second one I have the default two. On the pair I configured seven security contexts and everything works as expected; so far so good. Let's suppose now that the first ASA (the one with the license for 5 contexts) goes up in smoke; all the contexts migrate to the surviving firewall and life is still good. But what happens if, for some reason, I need to reboot the second ASA before the first one is repaired? My guess is that it will come up with just its own license for two contexts and that I will not be able to operate all my virtual firewalls.

We already know that ASA 9.0 supports site-to-site VPN in multiple context mode. But remote access VPN isn't supported. Obviously, SSL-VPN is a very important feature for most multi-tenant deployment scenarios where each context acts as a border firewall towards the Internet for each tenant. The alternative to terminate all tenant remote-access VPNs in one context means that each tenant would have to be routable from the ASA, which of course isn't a reasonable requirement in most cases.
So, what I'd like to do is to deploy an ASA cluster, and provide remote access VPNs for each tenant, where the connectivity for each remote access group can be addressed with whatever IP address space, and that goes into it's own VRF in the back-end.
As far as I can tell, this isn't doable with the ASA, since multiple context mode prohibits the use of remote access VPN, and I can't think of any other work-around than either having individual firewalls running in single context mode for each tenant, or demand that all tenants are interoperable routing-wise and configure a separate ip address pool in a single context mode for each tenant.
Essentially, there's no good way to implement this with multiple virtual firewalls, using cisco firewalls?

I am running a ASA 5510 in multiple context mode. IOS 6.4(2), ASDM 6.4(5)106.
In older ios/asdm versions it was possible to backup the configuration using ASDM.
In 6.4(5)106 i am missing this feature (see attachment)
Is it possible to backup a multiple context firewall using ASDM and above mentioned software versions?

I have a active-active setup with 2 cisco asa 5585x running 8.4 - the boxes ahve each 2 sec context's build-in - which gives 4 sec context in the cluster. I have 2 x 5 extra licenses (2 x ASA5500-SC-5) which I haven't applied yet - will this give me a total of 10 or 14 security contextes? I am a bit in doubt because if I only get 10 sec contextes in this cluster then could I instead get a single 10 security context license (1 x ASA5500-SC-10) and add this - hereby I would get 12 then.

On my production environment I have a firewall with already two contexts defined (15% of CPU used) and I want to add a new one.
This context is going to use the same interfaces as the others contexts. When I will enable the context, can I have some sort of repercussion on these two context ?

I know most QoS capabilities aren't available in multiple context mode, but I need to do some really simple policing on one of my contexts. I just want to apply a hard 20Mbps cap on an interface. I've seen a few places that suggest that basic policing is possible in multiple context mode, but apparently not by the normal commands.

I've got an ASA which has a number of contexts. They all share the same external interface, and in the interest of saving addresses I'm wondering if the standby address for each context is really necessary. I know that in active/passive the standby address is what allows the two to communicate and monitor that particular interface, however, in active/active I don't see the point as the context is either going to be on one or the other.

Im looking for some clarification regarding running a Cisco ASA in transparent mode with multiple contexts. To give you an insight into the network design we have the following -
Collapsed Core/Aggregation Layer running Cisco 3750s. The 2 Cisco 3750s are using SVIs with HSRP for default gateways per customer with a total of 8 customers. Each customer is segregated into seperate VLANs with Cisco 2960 switches used in the Access layer. Each customer has 2 Cisco 2960 switches with redundant uplinks to the Core/Aggregation layer. Customers are spanning tree loadbalanced between core/aggregation switches.
What i need to now do is add two transparent firewalls into the mix in either an active/active or active/standby setup. I need the firewalls to support all 8 customers, therefore I am guessing they need to run in multiple context mode. Having read into this it has left me somewhat confused as to how to integrate them into the above setup as a bump in the wire so to speak.

I got an ASA 5510 system currently in single context mode, with CSC SSM installed. Single ISP uplink to internet, no VPN. And now customer would like add another ISP uplink, without invest another box for HA.What come across my mind is make the current box into multi context. There's some area i need to concern and also need yours perspective on it.
Question 1: For making the firewall into multi context, am i need to do it from scratch, issue mode multiple command. Then rebuilt the current production config into one of the context, then another context meant for the new IPS uplink, and one admin context?
Question 2: For CSC -SSM licensing requirement, model ASA 5510 with security plus license is able to support 2 context. So if i split my firewall like what i mention in question, what exactly number of context do i own (admin, context A, context B)?
Question 3: For CSC-SSM module in multi context mode, so the management port of CSC SSM must attach at admin context?
Question 4: After configured all the policy and traffic to scan, how exactly i should do in order apply this policy to the interface? Should i only enable at admin context, then firewall service-policy rules, and apply it global, OR should i also do the same action on context A and Context B?

I need to replace an ASA with an IOS firewall router, and am not sure how to migrate the NAT configuration. Specifically, there is an interface "3rdparty" that has onward connectivity to other private addresses, so our internal addressing is hidden. For some reason there are static NAT rules in different directions across the interface, but at present I cannot see why. Thinking in router terms, all that springs to mind is the inside and outside tags for the interfaces, but also that it might need "overlapping" NAT to be configured.

We have a pair of cisco Asa 5520 currently running multiple context mode. We wish to change to single context mode for following reasonWe will migrate infrastructure to hosted vendor . I was thinking of configuring site to site . Current Asa we pal to kee since wireless sits in our DMz and we have net screen that hosts tunnel for erp1. Is context change required for running site to site2. Is it a good idea for creating site to site on to make sure wireless network and oracle traffic goes through managed firewall ?

I need to configure multiple context mode with active/standby failover solution.
Even after reading some Cisco documents I still can't understand if active/standby failover configuration has to be done within the admin context only or also within every single context (context-1, context-2 for example). In this case I have to allocate as failover interface a subinterface for each context (admin, context-1, context-2), right ?
Therefore a I have an other question: within the admin context, in a failover solution, do I have to allocate all interfaces I want to be moniotred, even though some will be used by context-1 only context and some others will be used by context-2 only context ?
An other question is: if active/standby failover configuration has to be done within each context, can I set regular failover within context-1 while stateful failover within context-2 ?
The last question is: can I use management interface within all 3 contexts ?

On ASA 5515 it shows it is in transparent mode and it has multi context.As in transparent ASA we know it has single Management IP address.This ASA is connected to one switch on two ports gi2 and gi3.One port carries vlan say 800 to the ASA.Other port carries vlan 500 from the ASA to switch But when i log onto ASA and do sh run it shows no VLan info there.

what´s going on with an asa540 configure in multiple-context mode. I Have a cacti server on my lan and now I´m try to monitoring the interface with snmp. When I try to get this information returns the error message:
CISCOASA/CONTEXTA#
JUN 11 2013 01:52:00: %ASA-1-1-6021: Deny UDP reverse path check from 10.6.6.6 to IP_SRV_CACTI on interface inside
JUN 11 2013 01:52:01: %ASA-1-1-6021: Deny UDP reverve path check from 10.6.6.6 to IP_SRV_CACTI on interface inside
If I try to ping returns the same error:

Following attached the conf of my asa My question is Why I can´t ping or even use snmp ?

My corporate internal network is currently fire walled by an FWSM module on a 6513 switch. We have each security zone (we have eight) assigned to a FWSM context and have ACLs set up between the contexts and the enterprise LAN/WAN. Is it possible to support fire walling between these zones within a single security context? The reason I am asking is that we would like to purchase a second FWSM for use as a standby, but do not want to cough up the ~ $12K for the context license. We will ultimately be transitioning to ASAs for internal security, so do not want to spend more than we need to.

We have a 5585X running in multi context mode, and we are getting log entries for scanning threat detection, such as:
%ASA-4-733100: [ Scanning] drop rate-1 exceeded. Current burst rate is 2 per second, max configured rate is 10; Current average rate is 5 per second, max configured rate is 5; Cumulative total count is 3116
Threat detection is not supported in multi context mode so I cannot tune the thresholds, is there any way that I can get rid of this outside of messing about with logging levels/message IDs?

This is a newbie question regarding CSS11500 series loadbalancers as I trying to get up to speed with managing them as part of my job. I noticed that there are a couple of CSS "clustered together" since I see they are managed using a single ip address.
My question is around how to establish a session to each individual device in this cluster, if at all possible? If is not possible, how do manage the secondary device in this cluster to perform tasks such as copying new software to it, backing it up, etc.?

I have two ASA 5520s in Active/Standby. I try and test this quartely to ensure it is working correctly. Everything works fine, except I have an issue with one interface. When doing a show failover, it shows the interface as failed on the secondary unit, and I am not sure why. It shows it as normal on the primary.
This host: Primary - Active
Active time: 9277305 (sec)
slot 0: ASA5520 hw/sw rev (2.0/8.2(4)) status (Up Sys)
Interface WaterworksCanopy (192.x.x.x): Normal

I'll be upgrading an HA pair of ASA 5520s next week, and wanted to clarify the procedure. I read "Upgrading an Active/Standby Failover Configuration" at [URL] which suggests placing the image on both units, updating boot statements, then issuing failover reload-standby. But I was wondering if there's a way to a way to be a bit safer. I'd like to modify the standby unit, without affecting the config on the active. So I'd like to modify the boot statement on the standby without modifying the active config. That way incase there's a problem and the active reboots, it won't upgrade.
Can I modify the config on the standby without affecting the active? Then I'd like to test the newly upgraded unit with our production traffic. Would that simply be no failover active, and then once the standby becomes active -- test traffic? Once everything is okay, I would upgrade the second unit, and fail traffic back.

I am in the process of upgrading a client's firewalls from 5520s to 5525-Xs. I have 2 independent firewalls that are merging into a single firewall. Both of the source ones have a TON of user accounts defined for remote user VPN, is there any way to move these user accounts with passwords in tact?? The goal is not to have to tell the 250+ users that they need to reset their passwords at once.

We are deploying the Cisco ASA 5585 in transparent mode with multiple contexts, the port-channel was configured to connect to the core switches using dot1q trunk. We are experiencing an issue which is the core switches are configured loop guard globally, therefore the port-channel connected to the firewalls will be put into inconsistent state when the failover happen, and the two firewalls' failover can not fulfill the failover at last.
I have two queries below:
1. Does the firewall allow the BPDU passing through when it is in standby mode, for example, secondary firewall is active for group 2 and standby for group 1. does the secondary firewall block the BPDU from the vlans under group1 ?
2. Can we disable the loop guard feature on the switch port-channel or is there any other way to solve this issue ?

I have two ACE working on active-standby mode, I have one context configured on bridge mode, with two vlans, the client (vlan 100) and server (vlan 101) sides.I need to balance another service for two servers (different from the ones on the first context ) on the vlan 101, so as the documentation says i can't configure the same vlan on another context because it is already configured on the 1st context as bridge.so my question is the only way i could balance this service is to configure it on the same context??. or there is another way?.These are the design limitations that i have to do this:
1.- I can't change the servers IP address.
2.- The VIP which will answer the clients request is on the same IP network segment as the servers, for example: server1: 192.168.100.125, server2: 192. 168. 100.126, VIP: 192.168.100.124

1) In order to use AVC and WSE I need the ASA bundle that includes the SSD HD right? (ASA5525-SSD120-K9)
2) In order to have both ASA's in HA, do i need to order two Suscriptions (ASA5525-AW3Y-PR) or only one that is "shared" in the cluster?
