Cisco Firewall :: Cannot Access FWSM Via Session Command In 6513 (VSS Enabled)
Apr 24, 2012
Today i received FWSM from cisco (RMA), I need to configure it as standby unit for existing FWSM active/standby setup.
IOS on RMAed FWSM is 2.3.4 and cisco VSS supports FWSM IOS 4.0.4 and later.My issue is, I cannot access FWSM (IOS 2.3.4) via session command from cisco 6513 but could successfully consoled it without any problem. I have reloaded it twice and also tried to disable and enable power on it.
VSS#sh module switch 2
Switch Number: 2 Role: Virtual Switch Standby
Mod Ports Card Type Model Serial No.
--- ----- -------------------------------------- ------------------ -----------
2 6 Firewall Module WS-SVC-FWM-1 -----------
[code]....
why I cannot access FWSM through session command ?Whether this is because of older IOS ? If yes then how to upgrade its IOS ?Is it possible to upgrade IOS via FWSM console ? if yes, Do i need to test on different slot ?

I need your opinion regarding moving of IDSM -2 and FWSM Module from 7613 to 6513 chassis.Currently these two modules are in 7613 and we are not using either of them now we have to configure them in 6513 chassis. As you can see from the figure that traffic of all 3 core router i.e 7613 go to 6513 - to proxy ISA 2004 - 6513 - to Internet.
There are also some network attached with 6513 and we want to move both of modules to 6513 so that NetworkA/B/C/D/E which are attached to 6513 can also be configured for FWSM and IDSM -2.
I have a query regarding this migration:Do we need license for these two modules again for 6513 chassis?

As I am planning to deploy FWSM Module in 6513 chassis and need your valuable comments regarding the strategy that I create for this deployment.Initially (Without FWSM Deployment) all internal traffic moves in this manner.
7613(G9/5) --> 6513(G10/4) --> ISA (Internal Int.) [NATing] (ISA External Int.) -->
6513(G9/45){This is L2 port in VLAN 164} --> VLAN 164(SVI Int,IP:192.168.40.20) -->
(G9/44){This is L2 port in VLAN 164}--> ASR 1002 -->Router -->Internet.
As you can see from the Image that I am planning to deploy FWSM in transparent mode in between VLAN 164(SVI Int,IP:192.168.40.20) -[FWSM here]->(G9/44){This is L2 port in VLAN 120}By putting Inside interface of FWSM in VLAN 164 and create a new VLAN on 6513 i.e VLAN 120 and put G9/44 in it.know will this configuration will work regarding the passing of traffic through FWSM ? what improvement I have to made in this design. You can check the attached diagram.

We have a customer who has 4 x 'WS-SVC-FWM-1' modules installed within 2 x 6513 chassis. The FWSMs are all running version 3.1(16) with failover group 1 and 2 enabled.After a few recent planned and un-planned power outages the FWSMs have come up without a full configuration. Is this a common fault? If so it there any kind of workaround that can be implemented?

I am trying to make the multicast working between few hosts inside a single vlan. Host are running mysql cluster and Multicast is used to send master/slave status information to the IP 228.10.10.10 on port 45566.The vlan is defined in FWSM and the host are connected via the core-switch(6513). (hosts-->core-sws--->fwsm)I have tried searching the documentation, but couldn't find specific info to enable multicast between hosts residing in same vlan. FWSM is running code 3.1(4). since the hosts are residing in the same vlan, I am thinking of applying the <multicast-routing> just for that SVI in FWSM.

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.

I have a need to capture some traffic but my core 6513's are already using the limit of 2 span sessions. I can't edit any of the sessions either because I want to source traffic from vlans and you can only do one or the other. Is using a VACL with 'switchport capture' on the destination interface an option ? E.g. I want to source traffic from vlan 10,20,30,40 and send the all to interface Gi10/10 ? Is there any caveats ? I dont need to be too granular with the ACL's but just capture all traffic in those vlans.

My company has acquired a Catalyst 6513 with a FWSM module installed on it. I have been reading lot of documentation on [URL], but still have some problems configuring the FWSM:
The 6513 has 10 SVIs configured, each of them with an IP address. These 10 SVIs are binded to 10 VLANs which I need to secure. These SVIs are used for routing all the Inter-VLAN traffic inside the switch. The documentation says it is recommended to use just one SVIs for connecting the switch to the FWSM, although you can use more than one using the command "firewall multiple-vlan-interfaces". I don't want to use this command because it seems a pretty more difficult configuration, since you have to use policy routing after using this command (or that is, at least, what documentation says).
When I try to "send" to the FWSM more than one VLAN that are configured as SVIs on the switch I get this error message:
"No more than one svi is allowed, command rejected."
If I delete the IP address of those SVIs, then I can to "send" those SVIs to the switch with no problem at all. But I need the SVIs to have IP address configured, since they are needed for routing Inter-V LAN traffic.
So, the question is: how can I route all the inter-VLAN traffic using just one SVI on the switch? Should I use the FWSM for inter-VLAN traffic routing?

We have 2 6513 switches with SUP720/PFC3A and various POE modules and a 6748-GE-TX facing our servers. Additionally, we have a 4Gbps portchannel trunk interconnecting the switches. We have approximately 300 Nortel IP 1140e phones in use between the two switches.For the purpose of call recording, we've attempted to mirror the voice vlan using various approaches and have been met with limited success. We mirrored the VLAN using tx, rx, and both. When using both we appear to get duplicate packets at the destination interface.We seem to lose packets completely going in one direction or another for a given call. Packets are lost before they get to the destination interface?

I was working on adding a Cisco 6513 to TACACS but ran into trouble. While I work on the issue offline (recreate and test another switch), I wanted to place this switch on radius temporarily.
For some reason i cant undo/delete the AAA commands in order to point to my radius server. Below was done via console: [code]
I disabled my telemetry port on the Cisco 6513 as a precaution. The IOS im using is "s72033-advipservicesk9_wan-mz.122-33.SXI5.bin".how to remove the AAA authentication statement. Hope its not intrusive cause i have a customer on the box.

I am unable to remove an access list. Currently this this access list contains 4 lines of remarks. I was unsure if I was entering the command correctly and now I have 4 lines of "trash" that needs to be removed.
Symptoms:
The "sh run" command shows that I have access-list 100 defined.
The "sh access-list" returns nothing.
Process I have tried: config t
no access-list 100
no access-list remark Test (just trying anything at this point)
clear configure access-list 100 (This returns "Invalid input detected at '^' marker" and the '^' is under the 'e' in clear.)
So the "clear configure" command is not working. The "no access-list" commands does not return an error but does not remove anything.
What step am I missing? Let me know if I can provide any more information.

We are running a FWSM and have created ACL's for a new Lync install. One of the rules needs to have port 5061 access from any source to our front edge server for communication. When looking at the logs I see a hit on the ACL but nothing ever actually connects.
One possible issue I see is possibly in the inspect:
policy-map global_policy
class inspection_default
inspect ftp
inspect h323 h225
inspect h323 ras
inspect rsh
inspect sqlnet
inspect sunrpc
inspect xdmcp
inspect sip
inspect netbios
inspect tftp
inspect pptp
class class_sip_tcp
inspect sip
In the inspect sip this is only for port 5060. How do I set this up to allow port 5061?

I've noticed that when using the range command to configure multiple interfaces on a 3750 the SSH session oftens hangs. It's seems the more interfaces in the range command the more often it hangs. I have a feeling it also spikes up the CPU. Doesn't seem to be related to a specific version of code.

We purchase a new 3945 router and a NM-1A-T3/E3 card. We would like to use the T3 funcationality so we enabled the command card type t3 1 (slot1), reboot the device.After reboot the sh ip int brief command should show the serial interfaces e.g serial1/0.In this case it doesn't, it shows the Gigi interfaces and ATM1/0 no serial interfaces.I've also tried upgrading to the latest IOS from cisco.

I have a Cisco Catalyst 2960 with IOS Release12.2(53)SE (because of a contract I can not update it) -> the release notes for this version describe the following:
When auto-QoS is enabled on the switch, priority queuing is not enabled. Instead, the switch uses shaped round robin (SRR) as the queuing mechanism. The auto-QoS feature is designed on each platform based on the feature set and hardware limitations, and the queuing mechanism supported on each platform might be different. There is no workaround. (CSCee22591)
My config is as follows:
interface FastEthernet0/1 switchport access vlan 200 switchport mode access srr-queue bandwidth share 10 10 60 20 priority-queue out mls qos trust dscp auto qos voip trust no cdp enable network-policy 1 spanning-tree portfastMy question now is:When the priority queue is not enabled with auto-qos because of the software bug is it nevertheless enabled with the additional priority-queue out command?

we just bought a 2921 with the following modules: 4 port clear channel T1/E1 HWICSM-ES3G-24-P: EtherSwitch.I read some CISCO documents, and not be able to find what I need. I would prefer all instructions from you are for CLI interface.This is my first time to deal directly with T1, WIC and 2921 etc. The following is what I get from ATT, IP masked IP Address Block IP Address: 20.20.20.136/29 WAN Link Details: WAN Link IP Address:13.13.13.92 AR Serial INT IP Address:13.13.13.93 CR Serial INT IP Address:13.13.13.94 WAN Link Subnet Mask:255.255.255.252
A: how do I configure T1, what does "AR, CR" stands for, and do I need to use both IP addresses? What is the WAN Link IP for?
B: We have two T1 lines, so I should plug them both to the WIC, say port 0 and port 1, how to configure them?
C: how do I access the firewall from the command line?
D: I followed T1/E1 HWIC installation guide, and as soon as I add channel-group to the controller t1, the serial interface went down?

We have two catalyst 3560 switches running c3560-ipbasek9-mz.122-58.SE2.bin They are connected using etherchannel using gi 0/21 - 24 interfaces.
on 3560-1 switch, there isn't any ip-default gateway or ip route configured. It only have 1 interface vlan configured.
on 3560-2 switch, there is ip default gateway configured along with 1 interface vlan.
What i dont understand here is that, i can reach out to other subnets from 3560-1 switch in which the routing is not enabled?

we have a chassis 6513-E and a module WS-X6748-GE-TX, I'd like to know if could I put this module in any slot, since the documentation from Cisco says that any slot from a chassis 6500-E Series can support this module. And then in the documentation of WS-X6748-GE-TX says that this module is not compatible in the slots 1-8 of the 6513 chassis, only from 9th to 13th slots, in those slots from the 6513-E we already have 4x WS-X6748-GE-TX, and we'd like to know if could we put the module in the rest of the slots. The 6513, and 6513-E is kind of confusing.

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).

I have a FWSM in my 6509, this firewall is managing three VLANs, one of which holds a file server. As you all know, FWSM do not support VPN like the ASAs and PIXs do. I have been trying to add remote access to this file server LAN all week. The only VPN device i have is a 2801 router.
first layout: VPN router behind FWSMstatic translation from FWSM LAN (private) to VPN WAN (public)default route was facing back at FWSMip address pool was to be NAT'd on the interface facing the FWSM the idea was that my VPN address pool would be NAT'd back to the FWSM on it's VLAN. since the FWSM was managing this VLAN and recognized the source IP of the translated address pool, i would have access to my precious file server.
second layout: VPN router fa 0/1 on a /30 with 6509 (public)VPN router fa 0/0 still on the same LAN as FWSM (private)address pool for VPN once again NAT'd to fa 0/0default route pointed to fa 0/1static route of FWSM LAN pointed to fa 0/0 this idea was to have more of a 'inside' and 'outside' interface on the VPN router. this too did not work, having used every trick in the book, i could still not ping anything on the FWSM LAN while VPN'd in the network (aside from the LAN interface on my router)
trace route was showing that the all routes were headed out fa 0/1 (default route) and all to my FWSM died. i really don't think my address pool is being NAT'd, though my route map statement applied to the NAT policy is permitting my VPN address pool.
I am new to VPN technology, one of those things that happened to land on my lap. how this layout could work? there are no good VPN Remote access walkthroughs for a situation like this (2801 allowing access to a FWSM controlled LAN)

We recently deployed a FWSM on our 6503-e boxes (w/ sup720). NAT is working (PAT) but the issue I am seeing is private traffic from remote sites is not being allowed through the FW. I was able to get the remote site to ping the FWSM itself (inside address), but no hosts behind it. Maybe an ACL issue? Also when I turn off NAT on the remote end, I can than access everything (We are NATng on both ends). Im a routing guy by nature so I will defer this to the security guys out there.
Topology
Hosts (inside/10.15.25.0/24) > FWSM (outside/public IP) -> Core Router -> MPLS CLOUD -> Core Router (NATng) - > Hosts (192.168.1.0/24)
ACLs applied to inside/outside interface
FWSM# show access-list ATX-ALLOW-IN
access-list ATX-ALLOW-IN; 15 elements
access-list ATX-ALLOW-IN extended permit tcp any any (hitcnt=222)

I have FWSM's in Cat 6513's. I have a need to be able to session from the switch to the FWSM by using default account (not local user), at privilege level 15 I further have a need to allow a user read only access by ssh'n into the FWSM...
I believe I need to setup a local user, at, say privilege level 5, assign the show command only to privilege level 5, then set the authorization command for that user. So, i think my command sets are as follows to accomplish this:
username <username> password <pw> priv 5
priv command level 5 mode exec command show
aaa auth ssh console LOCAL
aaa auth enable console LOCAL
aaa authorization command LOCAL
I think, that this will allow the user at privilege 5 to run only the show command and only by SSH to the FWSM while allow the priv 15 level default login to continue to function properly.

I have configured my Cisco 881 and finally got past the "Cannot see my network" with IPSec VPN issue.I have a usecase where I need to access the gateway from the VPN Session.When I connect to the VPN using Cisco VPN Client 4.8x, I do not get back a Default Gateway on the VPN Adapter. When I try to ping my LAN Gateway IP (10.20.30.1) it does not respond and I cannot access it with any other tools.I am pretty sure this is a very ACL issue and it makes sense to hide the gateway by default but the big question is how do I configure my router to see the Gateway and be able to access it from the VPN session?

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?
