Cisco Firewall :: Fail Context From One FWSM Over To Other 6500

Oct 23, 2012

Firstly is this the right forum to post threads about FWSM's. We have 2 FWSM's in two seperate 6500 switches. There are a number of contexts on each FWSM.I want to fail a context from one FWSM over to the other 6500 and FWSM. Can you tell me how I can do that? Do I need to do it in the admin context and do I need to do it on the admin context of each 6500?

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.

Cisco Firewall :: 6513 - FWSM Multiple Security Zones On Single Context

Nov 7, 2012

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.

Cisco Firewall :: 6500 - Upgrade Context License

May 3, 2011

I have a firewall module in a Switch Catalyst 6500. I wan to  upgrade its context capacity to a greater capacity. When I looked it in the Dynamic configuration, it send me following number parts:
The first one is the license to have 20 context and the next one is upgrade from 20 context to 50 context. My problem is that I haven't could find a service support contract associate them.I want to know if they have or not service contract, because I can´t find them.

Cisco Firewall :: 6500 - FWSM - Not Passing Traffic Through Firewall

May 3, 2011

We have 2 FWSM modules in each 6500 switches. 1st module is having 04 firewall vlan groups with 18 vlan interfaces in a single context firewall. All are working fine with no issues. Recently we create one more vlan on MFSC and add into the same firewall module. However newly created vlan inside the FW is not able to communicate with outside and also outside users not able to reach newly created subnet. But within the firewall zones (other interfaces) it can communicate. Once we did packet capture we noticed that its hitting firewall outside interface only and when we ping we got TTL expired error. we have default routes to outside and there's no any route inside as new segment is within the firewall (no any hop).
I guess there's no limitation on number of vlans that we can assign on one firewall eventhough there is a limitation for number of vlan-group which is 16 max (but we are within that limit).

Cisco Firewall :: 6500 - FWSM And ACE S/W Compatibility

Aug 14, 2011

We have a pair of 6500s with Sup720 running 12.2(33)SXI3. Each has an ACE-20 (s/w A2(2.0)) and FWSM (s/w v3.2(15)). We have reached a limit on the number of rules we can configure on the FWSM, and have determined that we shall upgrade to 4.1(5), with ASDM to 6.2(2)F. A question has been raised regarding the s/w on the ACE-20 modules. Do we need to upgrade them as well?

Cisco Firewall :: 6500 - FWSM Linux

Dec 20, 2012

We run a 6500 with an FWSM with multiple security contexts as well as cascading contexts with a "shared V LAN" . There is a problem with regards to Linux machines and our shared network.

For example, we have three Linux machines in production, each in three separate V LAN's. For me to communicate to these boxes from one V LAN to another I must first ping the server. If I do not ping the server it will not bring up a connection like ssh or HTTP, etc. Below is the error I get from the FWSM that hosts the Linux server, but like I said once I ping the server the error goes away. We only have this problem with Linux machines, and it is a problem for all three of them. Is the FWSM having issues understanding something with all three Linux boxes? Below is the error I get at first, when I try to SSH from one V LAN to another V LAN with the Linux machine. 

6 Dec 21 2012 16:33:54 106015 22 63000
Deny TCP (no connection) from to flags SYN ACK on interface inside.  
Below is what happens when I initiate a ping to the Linux Server and then ssh again. Notice it builds the connection with no problem after the ping. During the ping it builds the dynamic translation, and then when I ssh it builds the TCP connection. Do you know why this could be?

Cisco Firewall :: 6500 - FWSM With Multiple Connections?

Aug 29, 2012

There is a 6500 switch with fwsm. We have extended 2 vlans from the ISP into the FWSM. Also there are atleast 10 other vlans for our internal network. We would like say half of the internal vlans to go out of the 1st ISP vlan and the remaining half from the 2nd ISP vlan. Is there a way we can do this in the FWSM?

Cisco Firewall :: 6500 - Introducing ASA Into Setup Instead Of Using FWSM

Jan 3, 2013

We are thinking of introducing ASA's into our setup instead of using FWSM for our firewalls with our 6500. Currently we use multiple contexts with the FWSM, as we provide hosting services for multiple clients and want them behidn their own firewall. My question is how can we make this happen with an ASA. Since with the FWSM we use the backplane of the 6500 and SVI's for all interfaces between them. For example if we have 20 clients what will be the ideal setup for us to use with an ASA. If we can infact use mutiple contexts how can we? Is there a way we can maybe bundle all the ports in the ASA into the 6500 as a layer two trunk port and continue to use SVIs to manage all the clients.

Cisco Firewall :: 6500 FWSM Vlan Interface

Jan 29, 2012

Is it possible for me to create 2 vlan interfaces on the 6500 and have them both in the same subnet?
For a specific customer requirement I would like to have a vlan interface on the 6500 as default gateway, sat in it's own vrf, and then route all traffic inbound and outbound to this vlan through the FWSM interface, preferably in the same subnet. I don't think this will be possible so just looking for confirmation either way.
As I will be running EIGRP between a pair of central 6500's and 2 remote offices it will make things much easier for me advertise the connected FWSM interfaces in to EIGRP for access in/out of all my VRF'd subnets. If I need another subnet for each VRF FWSM next hop then I'll have to reditribute a list of statics which I don't really want to do.
The reason I am not just using the FWSM as gateway is because I need to run HSRP across 3 different devices (another 6500 in a second suite), and failover FWSM will only give me 1 level of redundancy for those gateways.

Cisco Firewall :: 6500 - Passive FTP Through 2 FWSM Contexts Via VRF Instance

Mar 26, 2012

I'm having problems getting FTP to work through two FWSM virtual contexts which are connected via a vrf. All this is configured on a 6500 switch with the FWSM running 3.1(4)
At the moment we can make the control connection but when we issue commands the connection times out.
Looking at the logs we can see the initial connection made to the server on port 21 from the client, this is also seen on the second firewall context (nearest the FTP server). The data channel is then seen on the first context, made using high src & dst port numbers and initiated from the client, successfully passing the ACL/Inspection, then on the second context we see the connection being denied by the incoming ACL on the second contexts interface connected to the VRF instance.
The rules are identical on the contexts and have been made by copying and paste the rule using CSM, we are using the predefined service group 'FTP-Group' which contains both tcp 20 & 21. FTP inspection is at default on both contexts.
We have tested with Win XP (capable of Active FTP only) & Firefox 3.6.12 which is the connections we are seeing in the logs trying to do Passive FTP.
Is this a problem with teh contexts randomizing sequence numbers or TCP Normalization? Or do we just have a problem with the Inspection engine on one of the contexts (I would have expected to see this on both contexts if it was a bug).

Cisco Firewall :: 6500 / Static NATS For FWSM Contexts?

Jun 28, 2011

I am just designing a solution where a FWSM consists of 2 contexts initially and has a shared outside interface pointing to the 6500 switch. There are 3 subnets connected to each of the FWSM contexts. So if anyone wants to access these 6 subnets then a route would be needed pointing to the interface vlan of the shared interface on the switch. But that would not be enough to access the subnets.. I am sure we have to define static NATS to point them to the right context where these subnets reside.
The FWSM is running version 3.x code So say,, and reside in Context 1 and,, and reside in Context 2 in each of the context we would have to make three static NATS
static(inside1,shared) netmask
static(inside2,shared) netmask
static(inside3,shared) netmask
The same would go for context 2 as well
static(dmz1,shared) netmask
static(dmz2,shared) netmask
static(dmz3,shared) netmask
By creating these NAT statements, would the outside users be able to access the subnets residing in the context?

Cisco Firewall :: 6500 FWSM Module Upgrade Recommendation

I'm looking at upgrading our FWSM modules in our 6500's. They're the WS-SVC-FWM-1 modules.
We're running on version 3.2(12) at the moment and I'm looking to jump up to 4. Any recommendations around whether I should to go to 4.1(6) or 4.0(16)? There aren't any features in particular that I would need in 4.1 but want a good stable base to sit on for 12 months until I look at this exercise all over again.

Cisco Firewall :: 6500 Can Shutdown Vlan1 On Switch And Still Communicate With FWSM

Jun 17, 2012

It is my understanding that the FWSM for the 6500 series switches uses a 6 port Etherchannel on the backplane to communicate with the 6500 series switch.Can you shutdown vlan1 on the switch and still communicate with the FWSM? I was under the impression that you could not (although I am looking at a config with it shutdown)

Two get the primary up agian, I reset the hw-module and then no failover active on the secondary to return the primary as active. However, after this event, I start to experience strange issues with connectivity. Certain TCP src dst combinations will just not work.

Cisco Firewall :: 6500 Setup In Active / Standby Fail Over Configuration

Feb 29, 2012

I have been having an annoying issue for the past few weeks with my ASA setup. We are using the ASA as our Remote Access Gateway and originally had it setup in a Active/Standby failover configuration using 2 x 5520 ASA's.The original setup of the devices was that the 2 x ASA were setup in a failover configuration, with both of them connecting back to the internal network via a 6500 device. Because of using failover I created a VLAN on the 6500 and put the two ports that connect the ASA's into that VLAN. I then configured the VLAN interface to be the EIGRP interface for the neighbour relationship to the ASA's.
The problem I am seeing is that the EIGRP neighbour relationship between the Active ASA and the 6500 keeps flapping. It occurs abour 4-5 times every day at randmon intervals. Sometimes the neighbour relationship will stay up for 6-7 hours, other times it flaps every 1-2 hours. I initially thought it was due to the failover configuration so I removed one of the ASA's and removed all of the failover configuration, but the EIGRP neighbour flapping problem still exisits. [code] Since removing the failvoer configuration I am thinking it could be a physical cable problem?

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 Application :: ACE And FWSM Design And Configuration Guideline With 6500

Apr 8, 2013

I have Cisco 6500 with FWSM and ACE module which are in one central DC. Also we have four different Datacenter (Hub & spoke) and in our FWSM we have configured four contexts in central DC FWSM for each DC. Each DC servers are different VLAN and IP subnet. Now we have to configure ACE module for load balancing among those different subnet servers. What will be the design and configuration for this solution? Like routed or one-arm mode design.
Scenario Example:
1.  App Server01
FWSM Context: DC1
Physical Location:DC1

Now customer requirement is we have to load balance using ACE between these App Servers which are in different context s in FWSM and one Server is not FWSM. how to configure or design or placement of ACE and FWSM for above scenario.

On the router, I ran the following command to set the default FWSM boot partition to the configuration with:Router#boot device module 4 cf:5 However, it appears the "show boot device" command has been replaced with "show bootvar" which doesn't show me which partition the router will boot the FWSM to. Is there a command I can run from the Router that will actually confirm the boot partition for the FWSM if the router reloads.
