I want to capture packet on gi0/0 of PE1 in order to show customer that all his traffic is encapsulated and transmitted by L2VPN (ldp signaling) in his lab.
PE1 and PE2 are Cisco3945 and L2VPN is working well. I tried cisco RITE(Router IP Traffic Export Packet Capture) feature, but the output was not what I expected. I tried both export mode and capture mode. Only LDP hello message I got, looks like RITE is only interested in IP packet. Monitor session wasn't effective as well because it is not a switch.
Is there any other way/workaround to capture customer's traffic encapsulated in L2VPN?
What I did on PE1 when I was trying RITE export mode:
ip traffic-export profile test

I'm trying to use EPC on ASR1001 running IOS-XE 3.4, and it won't work. Configuration commands are accepted by the router, but there are no packets in the capture buffer.In release notes for IOS-XE, in the 2.5 section, there is a statement that EPC is not supported on ASR1k. Is it true also for newer versions of IOS-XR?
I have a need to capture traffic on an ASR 1001 subinterface, but what I have found is that the Embedded Packet Capture feature is not supported on this platform. Are there any simple alternatives to capture egress traffic on a subinterface or am I SOL? This is a walk in the park on normal IOS routers...
I have a piece of software that I suspect is sending unwanted data over the internet to some IP address. I'm not an expert in anything related to computer networks, but I figure I could use such software after playing around a little with it.What application could I use that would so the following:
a) capture all the bytes the application is trying to send out so that it seems to the application it is doing it and see the place it was trying to send it
b) after inspecting the data, if it was ok, send the packages to wherever it was supposed to go so that it seems the original application sent.
I would like to capture packets which are going through an IPSEC tunnel. The packets originate in the appliance (syslog) and are sent to the remote via a VPN. I can see the encapsulated packets going out to the peer and I can see the ISAKMP packets to and from the peer. Because the packets originate within the appliance, they do not appear on any interface to be captured.
Is there some way to capture these packets before they are encapsulated?I attempted to capture packets on the asa-dataplane, but they are in a format that I cannot decode, and I cannot put a filter on the capture.
I operate between c6509-E, what did you flooding? its just packet capture gi1/3 but i dont know it and is it attack?also same seq no switch gots it?what is problem?
how to capture the incoming and outgoing packets on the balancer?The load balancer is connected in between the customer DCN and cisco switches 2960.The reason of capturing both incoming and outgoing packets on the balancer is to prove to our customer that there is no packet loss issue on the balancer, and it could be some issue on their DCN network.Since it is a production server, I will need to ensure that there is no impact to the incoming and outgoing traffic on the balancer and other networking equipments as well.
I have always done my port monitoring (SPAN) on Cisco layer 3 switches with no issues. This time I am trying to do this on a Cisco 2901 router:
Cisco IOS Software, C2900 Software (C2900-UNIVERSALK9-M), Version 15.1(4)M2, RELEASE SOFTWARE (fc1) System image file is "flash0:c2900-universalk9-mz.SPA.151-4.M2.bin
I need to have the source port gig0/0 and destination port gig0/1. There is something about the gig port enumeration (slot/port#) that makes the command rejected. It is self explanatory:
#sh ip int brie Interface IP-Address OK? Method Status Protocol Embedded-Service-Engine0/0 unassigned YES NVRAM administratively down down GigabitEthernet0/0 xxx.xxx.xxx.xxx YES NVRAM up up GigabitEthernet0/1 unassigned YES NVRAM up up Serial0/0/0:0 unassigned YES unset up up
[code]....
It doesn't matter what slot or port number I use, it is always rejected. The command is rejected for Both destination and source gig interfaces. I tried a wide variety of slot/port numbers. To my best understanding the complete port names are: GigabitEthernet0/0 and GigabitEthernet0/1, so why does it think there has to be another digit after 0/0 or 0/1? Does it have anything to do with the Embedded-Service-Engine0/0 being administratively down?
ATT notified my company we have a virus infected pc on one our networks which sits behind a Cisco ASA 5505 running 7.2(4). The set up is a basic inside/outside NAT configuration. They gave us the destination ip address and port which the our pc is contacting. I have been tasked to track down the infected pc. I created the following access-list and applied to the inside interface:
access-list VIRUS extended permit TCP ANY host x.x.x.x EQ YYYYY log debugging interval 600 access-group VIRUS in interface inside
I enable logging to the console whose output did not list the IP address of the infected pc, only the ip address of the DNS servers we were using. I then used the following capture commands to try locate the internal ip address of the infected pc:
Neither step worked and the resulting console output overwhelmed the firewall in a very short period of time. Before attempting this task again, I would like to know if I am going about this the right way or if there is a better methodology?
I want to know how to configure kompella l2vpn between 2 cisco devices in CISCO IOS. We know Martinna l2vpn type runs on LDP. but kompella runs on BGP. I need the configuration for same..
Assuming I have the following setup: Cisco 7604 Cisco Systems Cisco 7600 4-slot Chassis System OSR-7600 Clock FRU 1 & 2WS-F6K-MSFC2A Cat6k MSFC 2A daughterboard Rev. 4.0 WS-F6K-PFC3B Policy Feature Card 3 Rev. 2.4 WS-SUP32-GE-3B 9 ports Supervisor Engine 32 8GE Rev. 4.6 WS-X6148A-GE-TX 48-port 10/100/1000 RJ45 EtherModule Rev. 4.1WS-X6548-GE-TX SFM-capable 48 port 10/100/1000mb RJ45 Rev. 11.3 The SUP32-3c says it supports both L2VPN and L2TPv3, however the line cards are effectively 6500 line cards and I was under the impression the 6500 didn't support these.
If the supervisor supports a feature does that mean it is globally supported on a switch? Or do I need to check the compatibility of these line cards as to if they support these features?
While troubleshooting high cpu due to interrupts on platforms like 6500 or 7600 we can capture the packets getting punted to the CPU using netdr or on 4500 I think we can even use monitor session. But is there a way where we can capture/sniff packets reaching the CPU on a 7206vxr with NPE-G2?
I have a router with a desktop computer connected to it and a laptop and other devices like psp's, tablets etc. How can i capture the packets that the psp or the tablet sents through the router from my desktop? Is there a program or something. Programs that captures packets usually does it from one computer ie the computer that is running the program. I need to capture all packets that goes through the wireless router. How?
I've got a client with a WLC 4400 series and WCS that wants to setup a public guest wireless access network. They want to have the users put in their email address to authenticate and they want to capture the email addresses to use for marketing campaigns. I know you can setup the login page to have them put in their email address, but i can't remember if you have to use an external web server to actually capture and record the email addresses.
I have a WLC 2500 which I would like to configure with guest access. I want to set up a web passthrough with email input. Is it possible to collect the email address information? Is it stored somewhere in the controller or do I need some external server?
We are trying to sniff traffic in one of our routers 2811 IOS 12.4(3f) capturing data into the flash memory and tftp later to one of our servers. We had followed the command procedure as it is indicate in Router IP Traffic Export Packet Capture Enhancements doc but it seems that the mode capture option is not alllowed in my router. My question is Why? I had read the doc and the hardware and software should support this feature.

I have a Cisco 857 which seems to be dropping connection on its public interface.I would like to see the logs of the ppp or something which may identify the problem of why the device has lots its connection.
I know what you can setup logs for a specific IP, but it is possible to setup logs for debug messages?Also what other logs would identify the problem?
Is there a way to configure a VACL capture on 3560-x, we need more than 2 SPAN sessions. Feature navigator indicates that this feature is supported but it seems like it's not implemented in the IOS yet.
I have an ASA 5505 and I setup a port with a PC connected to monitor the LAN interface. I see all the traffic from the LAN going out and traffic coming back in no problem. What I do not see the the AOL Instant Messenger traffic at all. I have WireShark on the PC and I filter for AIM traffic and I see nothing.
I recently upgraded my 5520 to 9.0.1 IOS. Today I tried to apply a capture to my inside interface referencing a simple ACL and I get this error.
ERROR: Capture doesn't support access-list <capin> containing mixed policies
I also created a capture for the outside interface with a similar ACL and it worked just fine. I can't seem to find anything on the web that gives me a clue to resolving the error above.
I have an HTTPS probe that sometime fail, sometimes does not fail.
[code]....
The probe that sometimes fails is the TEST-HTTPS. The TCP_443 probe works perfectly well.The ACE is configured in bridge mode.Is it possible to capture the PROBE traffic on the ACE side?
I am looking for a simple First name, surname and email in exchange to unlimited free access to our wifi. Would want the data to load on to Infusionsoft?
I have a capture set up of type "asp-drop all", and I am capturing certain packets with no indicated ASP drop reason. See output below (ASA 5510 with 8.0(5)23 code):asa5510-8.0# show capture, capture ASP type asp-drop all buffer 15000 circular-buffer [Capturing - 14912 bytes]
At present I have a WLC5508 as a guest anchor in a DMZ and a web-auth passthrough WLAN configured. There is a custom web bundle providing a terms and conditions page.
We want to start to capture the minimum data from a user that logs onto the guest wireless ( email address ) and would like to use the check email function on the controller - BUT - at the same time move from using the web bundle locally hosted splashpage on the controller to an external web server provided splashpage / walled garden.
From my understanding not sure that this is possible as the email check function is only valid in passthrough I think.

I need to capture packets from my device out to the internet... are there any utilities or something that I can use to hook into the router to do a packet capture for a device on my network so I can give my ISP some troubleshooting data.
