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 :: ASA 7.2 Adding A Context In A Multiple Context Environment

Jul 1, 2012

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 ?

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 :: 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 WAN :: 6509 Fwsm Multiple Subnets Routed On One Port From 3750

Dec 20, 2010

We have a 6509 that was connected to 2 other locations(location A and B) and our local lan (location MAIN).  We wanted to move the location A and B to a 3750 switch and only allow the traffic that needed to access our location MAIN to come through the firewall.  The only problem I ran into is that before location A and B were on different interfaces so in the 6509 firewall the routes for traffic to our MAIN location was done by static routes.
static (MAIN_intf,A_intf) netmask 0 0
static (MAIN_intf,B_intf) netmask 0 0


because it has a static overlap, which makes sense to me, but my question is how do I configure the network to get this to work?  Do I have to reconfigure my network and access-list?  Do I need to add more ports between the 6509 and 3750?  I'm not sure if this is the best way to do what we want. If something is not clear I'll try my best to explain the setup, but I just took over for our I.T. guy when he left.
I put instead I should have put the routed port is on a different subnet than the computer I'm trying to access.

our FWSM (in 6509) is not coming up, when tried to sesssion up using "Session slot 1 proc 1" command,It is giving error , "Tyring .....connection timed out remote host not responding".
In "show mod" command output at Switch in IOS console:  under Card Type Section:  it is showing Model & Serial Number correctly,  Under MAC address sectino: displaying some MAC address But in Online Diag Status, it showing "Unknown" for Module 1.
We tried re-seating in other slots, but of no use. Giving same error. Some of other forms are saying it is the issue with 128 Mb CF image problem, FWSM is no more reachable from 6509 IOS console. We even tried using FWSM console (using PC-Conse & LCP Console) but FWSM is not contactable.

Cisco Firewall :: 6509 - FWSM Log Messages

Jul 16, 2011

I think I got a strange behavior on a context of my WS-SVC-FWM-1 (on a Catalyst 6509 running IOS 12.2(18)SXF17a) that is running FWSM Firewall Version 4.1(3). This context sends these log messages every ten minutes:
Jul 17 2011 23:31:16: %FWSM-6-302010: 0 in use, 0 most used
Jul 17 2011 23:31:17: %FWSM-6-302010: 2245 in use, 107133 most used
If I issue the "show conn" three seconds later the log message, the output I got is: FWSM#   sh conn 1041 in use, 107133 most used
In another context on the same FWSM the log message sent every ten minutes is just this one:
Jul 17 2011 23:31:17: %FWSM-6-302010: 1358 in use, 72503 most used
Jul 17 2011 23:41:22: %FWSM-6-302010: 1590 in use, 72503 most used
In this case there is no the log message where the "in use" field and "most used" field are 0 (zero). why does the context send the message with the "in use" field and "most used" field 0 (zero).

Cisco Firewall :: 6509 / 2811 - NAT At FWSM

May 17, 2011

I have attached a drawing of our network.  We have two 6509's connected to two Cisco 2811 (onsite) that the ISP owns. I am trying to get one side up and running before I worry about redundancy and so forth.  For this reason I have set all the HSRP priorities to 110 on the left 6509.  I have HSRP running between the ISP routers and V LAN 101 of the 6509's.  This works as I can ping yahoo and Google just fine from the 6509 switch.  I can't get from my laptop connected to V LAN 23 to the internet. 

It doesn't even attempt to NAT as there are no translations.  I have public address assigned by my ISP configured between the ISP routers and my 6509 on V LAN 101.  I then have the public address assigned to V LAN 100.  I configured V LAN 100 on the switch and V LAN 100 on the FWSM with the IP address in the drawing.  I have my NAT statements and route in my FWSM according to the drawing as well.  On the switch, I have a default route to X.X.12.19 which is the VIP between the ISP routers.  I can reach anything on the inside of my network, including the old network addresses from V LAN 23.  
1. Is it best to do NAT at the FWSM or should I do it on the MSFC connected to the ISP routers?  
2. If I have to configure NAT at the FWSM, does this requires me to extend the public network down to the FWSM? 
3. I'll take any examples you may have as I am stuck.

Cisco Firewall :: SSLVPN 9.0 / Web Vpn In Multiple Context Mode?

Mar 11, 2013

We already know that ASA 9.0 supports site-to-site VPN in multiple context mode. But remote access VPN isn't supported. Obviously, SSL-VPN is a very important feature for most multi-tenant deployment scenarios where each context acts as a border firewall towards the Internet for each tenant. The alternative to terminate all tenant remote-access VPNs in one context means that each tenant would have to be routable from the ASA, which of course isn't a reasonable requirement in most cases.
So, what I'd like to do is to deploy an ASA cluster, and provide remote access VPNs for each tenant, where the connectivity for each remote access group can be addressed with whatever IP address space, and that goes into it's own VRF in the back-end.
As far as I can tell, this isn't doable with the ASA, since multiple context mode prohibits the use of remote access VPN, and I can't think of any other work-around than either having individual firewalls running in single context mode for each tenant, or demand that all tenants are interoperable routing-wise and configure a separate ip address pool in a single context mode for each tenant.
Essentially, there's no good way to implement this with multiple virtual firewalls, using cisco firewalls?

Cisco Firewall :: 6509 / High Connections On FWSM?

Oct 19, 2011

I am having issues trying to track down what is causing a high number of connection on our FWSM in our core 6509 switch. I recently upgraded my FWSM to 3.1(20) and I'm looking for a tool to be able to find the culprit. When I receive these messages I try to get onto the firewall in time to be able to get information regarding this issue but by the time I do the device recovers. Is there a way to tweat the threshold of the SNMP trap for high connections? Is there any way I can retreive this information via SNMP? Is there are command that will allow me to extract the local IP making the most connections?

Cisco Firewall :: 6509 - FWSM With Packets Dropped

Jun 9, 2013

I happen to noticed the FWSM was dropping packets at about 387 packets every 5 minutes. My outside FWSM is WAN facing and has a 1gig link (35% utilized) my inside facing has about 100 downstream switches to the closets. I do not see my 6509's back plane is being over utilized and my understanding of the FWSM show be go for 5 gig so it isn't oversubscribe. Why i am seeing packets dropped?

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 :: 6509 FWSM Configuration With Shared Interface

Jul 2, 2011

I have attached a pdf of an example of a FWSM configuration with shared interfaces. Now what I dont get is (please refer to the link) url...Is there any difference between the natting that they have done on page B-4 on Context opposed to configuring a static NAT for processing traffic to correct context nat(inside,outside) other question is on page B-2 (diagram) Context A has a customer A network linked to the inside interface. Is it possible to put a default route towards that "Network 2" cloud and restrict traffic from the 6509 switch towards the context A?

Cisco Firewall :: 6509-E / Traffic Coming From GRE Interface And Going Further Through FWSM?

Oct 4, 2011

I have problem with traffic coming from GRE interface and going further through FWSM on the same 6509-E chassis.It's very interesting and confusing. If packets are fragmented, I can go through, however, if I use normal packets (usual ping for example) traffic goes from outside to inside and stops on it's way back.
Here is the detailed info:
WS-C6509-E with WS-SUP720-3B
FWSM HW 4.0,  SW 4.1(4) 
GRE is done in hardware (source is loopback interface - only one loopback per GRE tunnel).

Cisco Firewall :: 6509 - FWSM To ASASM Object Conversion

Nov 4, 2012

We are in the process of migrating to the ASA service modules on both our 6509E switches from our current FWSM. We have used the Cisco conversion tool and applied that to the service module. When viewing the context in ASDM we are unable to view the object names in the right hand pane.
On the FWSM I would see the following under Network Objects:
Network Objects
- JQ-Test
- JQ-Test2
- JQ-Test3
Network Object Group
+ JQ Group
      - JQ-Test
      - JQ-Test2
      - JQ-Test3
Now I have run the conversion tool and applied that to the ASA's I now get the following results.
Network Objects
Network Object Group
+ JQ Group
I am aware that the naming convention on the ASA's are different to the FWSM as you can no longer use the "name JQ-Test1" format but I was hoping that the conversion tool would do this for me.
Is there any way I can get the names of the object back without having to script something that takes the old FWSM format and convert it into an ASA format?

Cisco Firewall :: Migrate To Multiple Context Mode On ASA 5520s Cluster?

Jun 4, 2012

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

Cisco Firewall :: 6509 - Standby FWSM Stuck In Sync After Reload

May 8, 2011

We have a setup of FWSMs configured in single mode in 6509 chassis. Both 6509 are configured in VSS. Recently I have upgraded the firmwre from 4.0(3) to 4.1(3).....before upgradation config sync was not having any problem.
After upgradation...If any one of the FWSM reload..while coming up it gets stuck in config sync and no command we can run on any of the unit and get the error as..
Configuration update in progress by another process. Also on stannby fwsm no running-config displays.
If we used # failover suspend-config on primary and then reloads the standby fwsm...standby boots up with startup config and when  # no failover suspend-config command runs on active fwsm..the sync started and completing succssfully within 15 sec..
Also failover works well..with #no failover active..

Cisco Firewall :: 6509 -Creating FWSM Intra-Chassis Redundancy

Oct 27, 2011

Currently we have two inter-chassis FWSM redundancy. I would like to configure them for intra-chassis.
Both FWSM's are in slot 7 of 6509 switches and i want to take secondary out from one of the 6509 switch and insert in the slot 3 of primary switch.
I addedd the following commands in my primary switch.
There were commands already present for FWSM in primary switch
firewall multiple-vlan-interfaces
firewall module 7 vlan-group 1
firewall vlan-group 1  2,3,777
to create intra-chassis redundancy i addedd the following command also there.
firewall module 3 vlan-group 1
after adding that, my firewalls worked fine but there was a issue with site loading. People from outside were able to access inside but from inside, we were not able to go outside.
do we need to clear arp from both FWSM's ? is there any other precautionary step, which we need to follow while working on it.
