Cisco Firewall :: ASA5585-X Multi Context Throughput

Apr 25, 2013

How do i measure the total throughput going via 5585-X.It has the firewall througput of 5Gbps. Looking at aggregate of all the interfaces traffic going through it seems about 4gbps is going through.
 
I use show traffic command and add up the trasmit and receive traffic on each live interface.Is that correct method and are there any more commands?

Cisco Firewall :: 5585 - BVI Doesn't Show Up In Multi Context ASA

May 7, 2013

I have an ASA 5585 in transparent mode, multi-context. It seems that the option to configure a BVI in one of the traffic contexts isn't there. In other words, while I see the option to configure a bridge group interface in the admin context, no such option comes up in the traffic context.

Cisco Firewall :: 5550 ASA (8.3) - Packet Tracer / Multi-Context Classification

Nov 22, 2011

I've been using packet-tracer for some time on and off with mixed results.
 
I'm running a multi context firewall with over 10 of the contexts sharing the same outside interface / network. All interfaces obviously have valid, unique IPs and also unique MAC addresses as mac-address auto is enabled in the system context.
 
This is an ASA 5550 running 8.3(2.10) interim so includes the fix for the well known packet-tracer classication failed bug.
 
So in theory, with firewall contexts on a shared interface the ASA should use the firewall MAC address to classify incoming traffic to the correct firewall and as far as I am aware, only fall back on using NAT to classify if the interface MACs are the same. In reality on my platform this doesn't seem to be happening and the classifier is using NAT to determine the destination context. I'm seeing this with live traffic (i.e. not generated by packet-tracer) in logs and can prove it by disabling certain NAT rules (there is some overlap with the IP addressing behind each firewall).
 
My question regarding packet tracer is this - in the above scenario with a shared outside interface, does packet tracer ALWAYS use NAT to determine the destination context? Or does packet tracer look up the MAC address of the ingress interface according to what context you are running packet tracer from? It appears that packet-tracer is using NAT in my case which could be just symptomatic of the potential bug I've described above rather than by design.

Cisco Firewall :: 5585x - Threat Detection Log Entries In Multi Context Mode

Dec 29, 2012

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?

Cisco Firewall :: ASA5510 Single Mode / Move To Multi Context Mode

Sep 16, 2012

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?

Cisco Firewall :: Multiple Context Active / Standby (ASA 5520)

Mar 8, 2013

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 ?

Cisco Firewall :: ASA 8.4 In Multiple Context Mode With Different Amounts Of Context

Jan 13, 2013

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.

Cisco Firewall :: ASA 5520 NAT And DMZ / Inside Network Configuration?

Jan 27, 2013

I am trying to configure a server(192.168.5.50) in DMZ(192.168.5.0/24) to be able to communicate with a domain controller(10.5.44.220) in the inside network(10.5.44.0/24). I made some configuration using ASDM(not familiar with the CLI) but not working and it caused existing NAT not to work, for example RDP(TCP 3389) connection to 38.96.179.220
 
The things I am trying to achieve are
 
1. two way commucation between 192.168.5.50 in DMZ and 10.5.44.220 in Inside for SecureAuthPorts and SecureAuthOutbound service groups

2. NAT for 192.168.5.50 mapping 38.96.179.50 for the service groups mentioned above

3. NAT for other hosts already existing

Cisco Firewall :: ASA 5520 Configuration Backup With Archive?

Cisco Firewall :: ASA 5520 SSL VPN LDAP Authentication Configuration Required

Oct 16, 2012

I've gotten to the point where I can test against active directory and get in, also I can get AD groups from my server on the ASA. My problem, I can't connect in via my AnyConnect client on my Android. I immediately get a "log in failed" and I know I'm using the right username/pass. Doing a little troubleshooting, I have attached my AnyConnect debug log and the results of the "debug ldap 255" command on the ASA. Also, I've used ldp.exe to determine I can connect in with the username/password combo I'm using.Combing through the AnyConnect logs I see a few instances of "global error unexpected" but no Google searches have brought up anything useful.

Cisco Firewall :: ASA 5585 / Identity Firewall With Single Forest / Multi-Domain

Dec 28, 2011

I have a question with regard to setting up the ID firewall on the ASA 5585 in a single forest, multiple domain windows network.Currently I have a semi-operational IDF at the top level but can't find users on the lower other domains, here is the setup:I have 3 domains.

[URL]
 
Both domains have a two way parent-child trust and I can look for users in AD Users/Computer on both domains.  I initially setup the ASA to look at domain1.test.com using an LDAP aaa-server per the IDF instructions, and then proceeded to configure the ad-agent.  I installed the adagent on the domain1.test.com domain controller configured the settings on that system and had no problem adding users to the firewall and getting functionality within domain1.  I looked to see if I could see domain 2 and domain 3 users and found none.  I went ahead and added the domain2 system to the adagent on the DC and the system says that it is up, but when I search for users is not pulling them from domain2.  Instead, it shows domain1 users as domain2user1.  I also configured another adserver in the ASA to search ldap on domain 2 to no avail.The cisco documentation states the following:•Before you configure even a single domain controller machine using the adacfg dc create command, ensure that the AD Agent machine is first joined to a domain (for example, domain J) that has a trust relationship with each and every domain (for example, domain D[i]) that it will monitor for user authentications (through the domain controller machines that you will be configuring on the AD Agent machine). Single Forest, Multiple Domains—All the domains in a single forest already have an inherent two-way trust relationship with each other. Thus, the AD Agent must first be joined to one of the domains, J, in this forest, with this domain J not necessarily being identical to any of the domains D[i] corresponding to the domain controller machines. Because of the inherent trust relationship between domain J and each of the domains D[i], there is no need to explicitly configure any trust relationships.Reading that it sounds like it should just work.  I had everything properly configured before I installed the adagent, but I'm guessing that there is a chance that you can't have the adagent on the top level DC and get to communicate with the lower level domains.

Cisco Firewall :: 6500 Admin Context On FWSM

Dec 3, 2012

I have just joined a networks team and will be working on two fwsm versions 4.0(8) in two 6500 routers. Now the fwsms seem to be virtualised with multiple contexts. The server team want a new context setup for a group of servers behind a vlan. [code]
 
This context just seems to have  two Vlans and a BVI interface. What is the function of this context and why we have 2 admin contexts?
 
Also another important question is on which 6500 do I create the new context? Is the admin context active on one 6500 just like other contexts and will sync across or do I have to create the new context on both 6500s.
