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?
[Code] ......
Our Cisco ASA 5510 running 8.4(4)1 just started dropping packets and our AnyConnect clients are seeing horrible performance. The system is extremely slow compared to just a couple days ago.Nothing has changed on the system. I can post the configs if needed.

I have done a "sho vpn-sessiondb detail svc" and I can see the dropped packets of the individual users, but cannot see why the packets are still dropping.how I can correct this and restore speeds?
Does the FWSM v 4.1.3 is capable to forward return packets to the MAC address that sent them to it first?
View 6 Replies View Relatedour 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.
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).
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.
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?
View 1 Replies View RelatedI 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?

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?
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..
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.

We have 6509 VSS with FWSM Module and we have created two context on it, one is INTERNALL CONTEXT othe is EXTERNALL Context? We have spanned various VLANS in switches and FWSM context level. All VLAN Gateways are configured in context level.
Activity description : We had planned migration of these devices into a new Datacenter, it was a planned activity. During migration of devices from one Dc to a new DC we broke the VSS and kept the primary running and removed the secondary switch and migrated this secondary to new DC and powered this device ON in the new DC and checked all the config was very much fine but this device was OFF network as secondary was brought to new DC just to limit the downtime during the primary switch movement.
During the activity ( Primary switch movement )We powered off the Primary switch and mean time before shifting into new Data center We had brought up secondary switch which was already existing in the DC was put live in the network and it was working fine without any issues.
Later we had moved Primary into new data center and tried to put into VSS with the secondary , during this period the secondary device into went into RECOVERY MODE and primary device was not responding and devices went off network and immediatly we removed the VSL link and brought up primary into production network without secondary online in the network ( Without VSS just stand alone switch ) network started working, but bringing up the primary we found that some of the VLANS in the FWSM was deleted and some VLAN had misconfiguration ( example : say original VLAN ip 10.200.112.1 has become 10.300.13.1 ) also some of the access list as well as SVI was deleted making configuration mismatch.
Wanted to know while syncronization b/n primary and secondary switch in VSS if we pull out VSL link would create this type of issues.

I have a couple of Switches Blade 3120, working as active-standby model (HSRP) on a new site deployment. There are other 20 sites more or less, working on the same model, without issues. But in this one, we are seeing a high cpu usage. The traffic going through the platform is 600Mbps (on peaks), and in this case we have 40% of CPU usage. Traffic should be close to 3 Gbps. When we tried to send the whole traffic through the platform, active switch began to drop packets on the majority of interfaces.
When we analyze the CPU usage, there is a special process called "HL3U bkgrd proce" always have the most CPU use, but we do not know what concerns. We do not know if it is caused because there are PBRs configured. It should not matter. How I mentioned, there are other sites working fine and have had always the same PBR number.
What is causing the high usage?. Is there a special debug we could to perform to diagnose the issue?. Also, we have seen a high interrupt CPU usage (9% in this case).

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.

Connected to the D-Link I have a Windows 7 Pro machine (64-bit, SP1) and an XP (home i think) machine (sp 2 i think).The SmartAX modem is set up to perform DHCP and DNS relaying and the D-Link has DHCP turned off and DNS relay turned off.The Win7 machine can access the network, get an IP address and access the internet without problems, regardless as to the status of the XP machine.The XP machine can access the network, get an IP address and access the internet with no problems ONLY of the win7 is powered up.

View 8 Replies View RelatedWe 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

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.
