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?
View 1 RepliesI'm working on a BoM for a customer and i need to offer an ASA5525-X pair in HA with AVC and WSE subscritption, I've two question:
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?
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.
View 5 Replies View Relatedwe 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 ?
Just looking for some good reasons why I should upgrade a Cisco PIX 515e cluster to an ASA Cluster to present to the business.
View 1 Replies View RelatedWe 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.
View 4 Replies View RelatedI 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.

So I have a cluster asa 5515X with management interface. i Would like to be able to connect to any of the member of my cluster on management interface, so i would like to fix a different ip on management interface on each of my node ip 92 and 91.

last night we tried to upgrade our cluster (2x ASA5520) from 8.0(4) to 8.2(3) and failed miserably.
1. Both units got the new image, but when we reloaded the secondary unit then we got the following strange message:
"Mate's license (10GE I/O Enabled) is not compatible with my license (10GE I/O Disabled). Fail over will be disabled."
After this message fail over was not there anymore and both units became active (!!!) which killed everything. Of course ASA5520 doesn't have 10GE and we have exactly the same units. What could be the problem here? Currently we run with a single unit with 8.2(3) and the secondary unit is switched off.
2. After the upgrade we cannot connect with multiple VPN sessions from the same client, this gets logged:
"Multiple sessions per tunnel are not supported"
This was working just fine with 8.0(4) and doesn't work with 8.2(3). Do we have to update something in the config or what is causing this? If you ask why we went with 8.2(3) instead of 8.2(5) then the answer is because we were testing that for several month in our secondary data center, but unfortunately only on a single ASA and not on a cluster. We couldn't go higher due to the 512MB RAM we have in all units.
And we had to upgrade, because we had crashes with 8.0(4) which was working fine for a long-long time.
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

We have a faulty FWSM module in Cisco 6509 switch in Active/Standby cluster mode
We have purchased a refurbished FWSM module to replace it. It has the same FWSM OS 4.0 (4) and is in factory default configuration
What procedures should I follow to make this unit live and sync the config between the current active unit to this one.

i need to upgrade ASA 5540 from 7.1 to 8.4 for secure connect feature of Cisco Jabber Configuration. Support forum guides that, i need to follow upgrade path from 7.1 --> 7.2 --> 8.0 --> 8.2 -->8.4 and also do a memory upgrade from 1GB to 2GB.

I need to use this feature for only three or maximum four users in company then would i really need to do memory upgrade? or can i go with 1GB memory?also how i can get the prices of part number "ASA5540-MEM-2GB=" at cisco.com?
ASA-ISB-HQ# sh version
Cisco Adaptive Security Appliance Software Version 7.1(2)
Device Manager Version 5.1(2)
[Code].....
ASA5540# sh run nat-control
no nat-control
this means higher security can talk to lower security without NAT rules
Question 1) - if I want higher security zone to to talk to lower security with NAT rules. I would use statements like below. Am I correct?
nat (dmz) 1 0.0.0.0 0.0.0.0
nat (inside) 1 0.0.0.0 0.0.0.0
global (dmz) 1 interface
global (inside) 1 interface
Is this correct? So in this case I am kindly of like overriding the no nat-control statement ...right?
Question 2) - Now I have no nat-control enabled. Would the below statements (nat 0) be of any use for NAT exemption??
nat (dmz) 0 access-list dmz-nonat
nat (inside) 0 access-list dbase-nonat
And do I have to have a global statement for NAT 0 ...like below?
global (dmz) 0 access-list dmz-nonat
global (apps) 0 access-list dbase-

View 2 Replies View RelatedI have a remote site customer with a Cisco ASA 5540 running SSLVPN (Anyconnect)(8.03). It currently only serves about 450 SSLVPN clients. Since last friday, they've seen the CPU utilization go up to high 90% while only serving 400+ remote users. I saw some high cpu utilization bugs, but none looked to be relevant. How I can find the root cause of the CPU high utilization?
View 2 Replies View RelatedJust upped our external ASA-5540 pair to 8.4(1), and now one of our nat's is busted.
Here's the lowdown:
Our public IP for our IronPorts ends in .167. That IP is natted to a VIP on our ACE, which load balances to the IronPorts.
The outside interface of the ASA uses .162, which has been the pat for all outbound traffic for a few years... except for the subnet that houses the IronPorts. Due to reverse lookup, that subnet uses the .167 IP address for all outbound traffic.
After the code upgrade, the nat won't work. No email sent or received. Nothing but Deny's on the ASA with flags reading either "SYN" or "RST". IE: Apr 27 12:56:11 10.22.151.41 local5.crit %ASA-2-106001: Inbound TCP connection denied from 69.25.174.17/36917 to 207.236.211.167/25 flags SYN on interface outside
If I return the subnet pat back to the outside interface, then inbound traffic works fine, though reverse lookup fails and anyone running a reasonable spam filter won't send to us.
I have two Cisco ASA 5540, these ASA running ver 7.2. and used mainly as VPN gateways.My question is simple, Apart from the extra AnyConnect client functionality and the higher encryption, is there any specific security benefits (related to the VPN use) for upgrading to ver. 8.x ?

I have 2 ASA 5540's that I want to run in HA A/F. The active ASA has an IPS module running. I no longer need this and would rather remove it than purchase another module for the spare. What is the process to do this safely? After removal will the HA wizard recognize that the module was removed or do I have to update the software?

Q1. I would like to confirm like how many total of contexts do I have by default when I purchase the ASA 5540 ? are they two contexts aside from the admin context or two contexts including the admin context?
Q2. can I configure the default box with High Availability using the default contexts?
Does ASA 5540 support BGP routing protocol to be configured on it??
I'm talking about the latest versions.
I have an ASA 5540 , how can i block softwares like TeamViewer , VPN Adapters like Hamachi and all. Also , I have tried URL Blocking but i suppose ASA supports only HTTP url block and not HTTPS.

I am in the process of rebuilding our ASA 5540 pair. We are currently on 8.2 code with this set of firewalls and I was going to upgrade it to 8.4 being I have a couple of other firewalls running this code currently and am familiar with it. That said, I saw that the 9.x code is out there now. Are there any major advantages or caveats with the 9.0 code? I plan to use this firewall with SSL VPN and RSA Secure ID integration for the next 2-3 years at least. Any quick pointers on these two code versions and on upgrading to 9 or staying with 8.4 line.
