Cisco Firewall :: Active Session Count Of ASA 5540 In HA?
Apr 15, 2012
We have configured our ASA5540 in active-standby failover.We are observing that current active session count is twice of session count before configuring HA. Earlier average active session was 50000 and now after HA it is around 100000. Failover configuration of both firewall are as follows
failover
failover lan unit primary
failover lan interface FOLan GigabitEthernet1/0
failover polltime unit 15 holdtime 45
failover replication http
failover link StateLink GigabitEthernet1/1
failover interface ip FOLan 10.3.3.1 255.255.255.0 standby 10.3.3.2
[code]....

I 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 Will the secondary (now active) FW sync it's config to the non-active FW, or will the failed FW sync it's out-of-date config - removing any changes that we've made in the last month or so.

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?

Any method to determine the maximum number of concurrently used SSL VPN licenses (sessions) on an ASA5540 over a period of time? For instance, over a week, the MAXIMUM number of concurrent users that were utilizing SSL licenses on the box. We are trying to determine current license capacity of the device.
We are running 8.2(5) on the ASA itself, and have 6.47 ASDM deployed.

I recently upgraded our head end ASA5510 at our datacenter from 8.2.1 to 8.4.5. The ASDM was also upgraded from 6.2.1 to 7.1.(1)52. Under the old code, a remote ASA5505 connected via Easy VPN Remote showed 1 IPsec tunnel. However, after the upgrade, it shows 42 sessions. It would seem to me that each split tunnel network defined in the Easy VPN profile is being counted as a tunnel. Is it possible that I may have something misconfigured now that the code is upgraded?

I have a Cisco 5540 that terminates one end of a L2L tunnel, the remote end is a Sonicwall TZ100. The tunnel is in place to carry voice traffic and I have a need to decrypt the traffic that's been captured in .cap file using Wireshark 1.8.5. How to go about getting the session keys from either device?

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.

we had such kind of issue: while installing 2 SSM-4GE modules to 2 ASA 5540 (Active/Standby) the firewall is splitted. That's my step:
1) Turn off standby ASA and plug SSM-4GE module
2) Power it On After it was booted up failover relationships were broked and previously stabdby became Active appliance.
3) Turn off active ASA and plug SSM-4GE module
4) Power it On
After the it was booted up failover comes up and previously Active (on step 2) appliance became Standby. Everything is up and running now, but the issue was on step 2, I suppose becouse of distinct in hardware (when one ASA was on SSM reachest than another one). Still have no ideas why so happens and is there any way to plug SSM modules int ASA active/standby cluster without downtime.

Our company has installed ACS Version: 5.1.0.44.6 Internal Build ID: B.2347 with patches: 5-1-0-44-5, 5-1-0-44-6. The security policy of our company includes a password change every 3 months. Our programmers had written a script that allows us to do it. When testing revealed that the script does not work. This is due to the fact that it is not possible to enter the mode "acs-config". In determining the reasons it was found that to enter this mode there is a limit on sessions (6 sessions). When the number of connections becomes larger than 6 then the script does not work. The documentation says that the update is not active sessions is set with terminal session-timeout. In this case, the terminal session-timeout 30. But after 30 minutes of the session will remain active. It interferes with our script.

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 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 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 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..

ASA v 8.2What does the ACL hit count count ? I always thought that the acl hitcount counted the numbers of packets hitting that line in the ACL, however that is not the case. if I setup a icmp permit rule then that will only increment 1 even if I send 4 packets that hits the line. udp and tcp seems to do the same. is there some way I can make the ACL actually count the packets that hits ? where can I learn more about this ?

I have several working VPNs between ASAs 8.4 and 8.3The way this was set up is with cryptomaps that match whole subnets and ACL on the outside interface to permit from/to the RFC 1918 addresses.I notice that the hit count is zero on these rules and so I wonder if they are actually necessary or doing anything.If they are not where can an acl be applied to restrict the VPN traffic? Outbound on the inside interface?

We are running a ASA5520 with system image of "disk0:/asa843-k8.bin". I'm also running ASDM ver: 6.4(7)So my question is while I'm in the ASDM on the configuration of the firewall, I'm looking at the Access Rules. When I do a show log on any of the rules that have hit counts on them, it opens up a Real-Time Log Viewer but I don't see any information. It's not showing anything, nothing appears, it just sit's there like it's waiting but no data is coming. Even though if I go back out to all the rules, I can see the hit count incrementing. The same thing happens no matter which rule I pick with hit counts on them.

At the end of the day I simply need to upgrade the license on my ASA 5505 v7.2.4 (upgrade will come later as part of a larger project) to allow for >10 Inside Hosts. From what I've read there seems to be a 50 license upgrade out there. Can this be purchased directly? From whom? Will it only affect the Inside Hosts number and not affect any other licenses, configurations, etc. Just being overly cautious since this is way outside of my normal realm. Below is the current activation-key information....
Result of the command: "show activation-key"
Serial Number: xxxxxxxxxxxxxx
Running Activation Key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Licensed features for this platform:
Maximum Physical Interfaces : 8
VLANs : 3, DMZ Restricted
Inside Hosts : 10
Failover : Disabled
VPN-DES : Enabled
VPN-3DES-AES : Enabled
VPN Peers : 10
WebVPN Peers : 2
Dual ISPs : Disabled
VLAN Trunk Ports : 0
This platform has a Base license.
The flash activation key is the SAME as the running key.

I need to count the bytes for some interesting traffic crossing the firewall in ASA 5500. Packet Capture is so far as I need, cause I only need the number of bytes during a long time for about 3 months (source host - destination host)
capture capin type raw-data access-list cap buffer 33554432 interface inside circular-buffer [Capturing - 33553570 bytes]
I need to get only the exactly amount of "33553570 bytes" The pcap file is not needed

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?

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-

I have inherited the support of an ASA5520 running 8.0(3)12 code and I believe I have a pretty simple question here that I haven't been able to figure out on my own. I have a few users that connect to the box via IPSEC VPN client connections. They want to be able to leave up a RDP based connection, for monitoring purposes, for a most of the day, but thier RDP connection keeps getting discounnted after a few hours. The VPN connection never gets disconnected, just the RDP session running through it. I have another box running 8.0(4) code and they can leave up the RDP sessions as long as they like without getting disconnected from the server(s). I have compared the configs of both boxes and don't see any glsring differences in regards to the configuration that would cuase the RDP sessions to either to stay up or be disconnected after an inactivity type scenario.
What to look for in regards to identifying the timer that is disconnecting the RDP session after a period of time.

I 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?

Just 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.
