Cisco WAN :: Slow Performance With FWSM In Different DMZ 6509

Aug 8, 2012

i am feeling an issue related to 2 x 6509 with fwsm.

on fwsm we have different dmz for different application. mostly of Oracle (1521 port) to application means seperate one. problem is oracle people reported the slow performace when exporting dump from once vlan to another. before that they are using 3com technology (network) and on this its ok. time difference is double from old to new.
 
i had sniffed the traffic also and found alot of TCP OUT OF ORDERS errors. i read that this is the bug which is resolved in 4.0.

Cisco Firewall :: FWSM (in 6509) Is Not Coming Up?

Oct 29, 2012

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 127.0.0.11 .....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
[code]...
 
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 :: 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 Switching/Routing :: 6509 Supervisor Upgrade With FWSM?

Oct 8, 2012

We are planning to upgrade the IOS on our two 6509E supervisors in the next few weeks. We currently run IOS 12.2(33) SXI1 and are upgrading to 12.2(33) SXJ3. At the moment the two supervisors are in SSO mode and after reading many articles it says that when the images are different on the two supervisors they are in RPR mode. When you then reload the active supervisor it will reboot all the line cards.
 
1. Is above correct? Will my line card reload?

2. We also have a FWSM installed, When/If the line cards are rebooted does the FWSM also reboot?

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 A.as opposed to configuring a static NAT for processing traffic to correct context nat(inside,outside) 209.165.201.0 10.1.2.0.The 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 Switching/Routing :: 6509 FWSM VLANs Do Not Show Up

Feb 7, 2012

Configuring FWSM in a 6509.  When I set "firewall vlan-group 40  40-42,251", it results in: "No more than one svi is allowed. Command rejected.". 
 
I had "firewall multiple-vlan-interfaces" set for a previous use of this module, but took that off with the "no" command.  Suspect that is the issue, but do not see how to resolve.  Seems similar to bug CSCsr48563, but I am at the fixed code for that bug.

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
- 10.1.1.1
- 10.2.2.2
- 10.3.3.3
 
Network Object Group
+ JQ Group
     - 10.1.1.1
     - 10.2.2.2
     - 10.3.3.3
 
I am aware that the naming convention on the ASA's are different to the FWSM as you can no longer use the "name 1.1.1.1 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 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.
 
I.E.
static (MAIN_intf,A_intf) 192.1.1.72 10.94.10.72 netmask 255.255.255.255 0 0
static (MAIN_intf,B_intf) 192.2.2.72 10.94.10.72 netmask 255.255.255.255 0 0

[Code]....

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 10.10.10.72 instead I should have put 10.94.10.72. the routed port is on a different subnet than the computer I'm trying to access.

Cisco Switching/Routing :: 6509 - VSS Active Chassis Both FWSM And VSS Failover

Sep 25, 2012

Any have experience on triggered failover on VSS deployment with 1 VS-720-10G-3C in each chassis? I tried using "redundancy force-switchover" but after that the 20G VSL is flapping up & down and cannot be up normally, we got 1 FWSM in each chassis, any configuration need to fit in this kind deployment? BTW, if I shutdown the power source of VSS active chassis, both FWSM & VSS can failover normally.

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.

Cisco WAN :: Why 2811 Performance Is So Slow

Dec 18, 2011

I recently inherited a small network. There is an existing 1.5mbps Internet connection (fa0/0) (includes MPLS as well/same provider). We added a new ISP that allows for 50mb down/5mb up. I added the new ISP to fa0/1 and modified the NAT overload statements accordingly. I alo changed the default route to ONLY use the new, faster ISP connection. Using speedguide.net, I am only able to get 6 to 10mb down, most of the time. if I plug a laptop into the cable modem then I get 37 to 50mb down. Why the 2811 is so slow?
 
I have attached the config and various show outputs (nat, sh ver, memory, etc.). the file called "latest logs" contains a "sh ip traffic, sh int switching and a sh proc cpu sorted". [code]

Cisco Switching/Routing :: 861 Router - Slow Internet Performance

Jul 21, 2012

I have a new 861 router which I have connected to my home broadband cable modem. Got it all working okay and I have access to the Internet but its not as fast as it is if I connect my laptop to the modem.
 
My Internet is 60mb (was 100 but I downgraded). When I cannot my laptop directly to the cable modem, I get 60mb download speed on speedtest.net If I connect the router's WAN port back to the modem then I roughly get about 40mb, sometimes even 50.
 
I do not have any IOS firewall configured on the router, just basic ACLs to stop SSH and TELNET from public networks. If I do enable firewall then my Internet connection halves itself. I have read around that this is the case with ios firewalls on these small routers so I've disabled the firewall but I still don't know why I cannot get full Internet speed.
