Cisco Firewall :: ASA 5585x Security Context In HA Cluster
Jun 6, 2012
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.
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?
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.

Is it possible have Content Security and Control Security in a ASA 5585-X? I´m asking because the CSC-SSM is only supported in ASA 5540, 5520 and 5510 and I dont know how it feature ca be supported on a new ASA 5585-X.
What are the new features added or going to be available on the 8.5 release on the ASA. Would this release "finally" support VPN on multi security context mode.
By the sounds of things looks like every other major vendor supports this feature except Cisco.
I have a ASA 5510 and planning to implement multiple context in a 2 tier security level and vrf-lite. meaning I have 2xASA facing the internet and below that a 2x3560 switch for our extranet and below that is another 2xASA for intranet. See diagram below. In this kind of network I want to know how it would impact the total throughput and resources of the ASA using multiple context?
I need your support for upgrading the Security context license on 5550, at present we have 5 Security context license installed in ASA but we want it to increased till 10 conctexts. I want to understand if we need to get addtional 5 Security context license or 10.
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.
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 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.
ASA 5510 security plus edition will it support active/active failover. and does it support context with securiyt plsu edition. and how many default context do we get with asa 5510 security plus edition.
Looking for a recommended code on the ASA 5585x firewall. We ran into a bug (CSCtr24705) on version 8.4.2 where it rebooted the primary firewall. The bug has to do with modifying an existing ACL that's part of a custom policy-map inside a service-policy. If we upgrade to 8.4.5 (which has the previous bug fix in it), there is another major bug (CSCud70273) where if you use the packet-tracer input command on an inside interface it causes problems too.
I don't understand why packet-tracer input would have a bug associated with it when it's been around for a long time and we use it on a daily basis for troubleshooting. Is there stable code for the 5585x to upgrade to without running into possibly a major bug? This is our core firewall so there are no VPN tunnels on it. It's setup in active/standby failover in routed mode.
we operate an active/passive cluster with 2 ASA5510 in Routed Mode. Is it possible to add another node, so that we have one active and two standby nodes in the cluster? Unfortunately, I have found no documentation on this .... The data sheet say only up to 10 nodes can be mentioned as a VPN load balancing cluster.
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.
I am wondering what is Latency value for Cisco ASA 5585X and 5555X . I can see on websites that it says "low latency firewall" but I dont see any value.
Looking to replace an "all-in-one" type firewall (UTM/Firewall, SSL VPN) with a cisco product - the issue i'm running into is that we have multiple ISPs plus WAN and DMZ - overall more than 5 ports on mid-range ASA devices - and from what i read, adding 4-port module precludes me from adding CSC module.
Is there an solution to that other than going for 5585-x model? (kind of over our budget, granted we need 2 for failover)
I have a circuit that will be delivered to a client next week and we are installing an ASA 5585x for them. They will have a circuit coming in with a few VLANs configured on it. One VLAN for the Internet and one for connectivity to another client.
So does the ASA allow you to create the "outside" interface on a subinterface?
I will be supporting a new ASA 5585X running 8.4 and I was wondering if it's possible to apply an ACL globally instead of it as an access group that is applied to a specific interface as in or out ... below are the interfaces and ACl.
I want to configure 5585x Active/Standby with 2 nexus switches utilizing VPC technology. New ASA 8.4 supports etherchannel so I want to plugin 2 cables from ASA1 to sw1 and sw2 and 2 cables from ASA2 to sw1 and sw2? Is this a valid design? how would I configure that? Any design document on that?
I have at the moment an ASA5510 pair in Multiple Context configured. Everything is ok, but we use til now only ACL features.Now I would be interested in configuring 2 contexts, with IPSec VPNs. One VPN per context. But I cannot find any information if it would be possible to use a shared interface for both contexts. My wish would only be to spare public IPs.If I have to configure 100 VPNs in 100 contexts, do I need 100 public IPs ?
We currently had to RMA both PIX 525s due to increasing crc errors. After swapping the old ones with the new we are still seeing crc errors on all gig interfaces. We have swapped the gig nic's and the sfp's and the fiber patch cables, yet still the crc errors continue to climb.
Another thing that's interesting is that when we disconnect the secondary we see an increase in throughput.
a customer have 2 pix 525 with ver 7.0.1 in a failover configuration with serial cable and 2 sc fiber interface and 2 fastethernet 1 used for failover. the strange behaviour is that when i try to do traffic from inside to dmz or dmz to inside the maximum transfer is 862Kb/s to 1MB/s not more.... i don't understand what's happened. the show mem and show cpu are normal 7% mem used and 1-2% cpu used. attached you will find the configuration.
Is it possible to use 1 or 2 of the 4 gigabit ethernet ports from one ACE straight into the other ACE for redundancy? So ACE_01 gig0/4 to ACE_02 gig0/4.If so, is it a case of just having the layer 3 config instead of trunking etc..Also - is it possible to create a context within the same vlan as the Admin context?
we are going to upgrade our 5580 ASA Cluster from 7.2 to 8.2 and want to do it like this way ( which worked for all 7.x upgrades ) :download asa8.2 Image to primary + secondary Firewallreboot primary ( message come up " mate version ...)reboot secondary.Does it works any experience? Does it work if both firewall can see each other during the boot process ?
Do I have to bring the secondary into the monitor mode so the fw is not visible for the primary ?
We have the following setup on our Cisco ASA version 8.6.1 One to one NAT rule from outside to our Exchange 2010 cluster IP address (DAG group). This is working fine for clients on the internet accessing their emails via Exchange using their phones. The ASA has the MAC address of the active node from the cluster but when the cluster failover it cache the IP address and are not updating the new MAC when the cluster failover. So users from the outside are unable to connect to the new node from outside the ASA as the MAC address from the passive node is in the MAC table. The MAC address on all the switches update within 2 seconds on the internal network and users don't notice any outage.
I have 2 cisco asa 5540's configured in active/standby mode. I need to change the hostname and domain name as per our standards. Does changing the hostname has any impact on the traffic flow?
