Cisco WAN :: 2811 - IP Traffic-Export Mode Capture
Apr 25, 2011
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.

We have a Cisco 2811 running ITP IOS. On that router we run the SMPP service. A client on the network connects to this service, and we need to capture the traffic for debug.
I've tried traffic-export, but I cannot see any outbound traffic.I'm guessing that this is due to the fact that the outbound SMPP traffic is not transit traffic as it is generated by the router itself.
Is there any way to capture the outbound traffic?

cisco 2651XM router with WIC1 adsl card and NM-16ESW switch
IOS: c2600-ipbasek9-mz.124-23.bin
I use the following config to export traffic from the adsl card to a fasterthernet port so I can look at the adsl traffic in wireshark on a pc:router(config)#ip traffic-export profile my_rite router(conf-rite)#int FastEthernet 0/0 router(conf-rite)#bidirectional router(conf-rite)#mac-address abcd.efgh.ijkl (mac address of PC) router(conf-rite)#exit router(config)#int dialer0 router(config-if)#ip traffic-export apply my_rite this config works and I can see stuff going on in wireshark but it's only one way. This config only shows traffic going out from my adsl card, but no incoming. There is defintely traffic going both ways because everything about my adsl connection is working perfectly. I've tried using a different fastethernet port, even tried exporting to a different pc but all I see is outgoing ie: source is my public ip address but never as destination . I have bidirectional in the config but it still only shows outgoing. I even tried a different IOS (c2600-adventerprisek9-mz.124-15.T8.bin) but still it doesn't show incoming traffic. Could it be my ISP in some way hiding incoming traffic from view?

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'm now trying to implement a IPsec VPN network over transport mode in my simple network environment.I got two Cisco 2811 routers connected each other and each router hosts a client PC running Windows7.
I have finished the configuration on both routers and make them running over transport mode.However, as what it should be, transport mode indicates the communication between two end stations (two PCs) the client PC (install or configure something) to make the network fully works?

We are having issues with our Cisco 2811 when there a lot of traffic on the device. Usually the router is down around 5%-10%. Total traffic might be around 2.0 MB. This is a router we are using at a remote campus. We do HD video conferencing every friday. We have a 10 MB internet connection that has our VPN connection to the main campus on it. While doing these VTC, the totall traffic is about 6 MB. The CPU Utilization then rises to approx 75% cause call issues and loss of sound. With another test with no one using the connection for anything else the utilization went up to 35%. The router has 128 MB Ram in it. Does the router need more RAM or do we need a larger internet pipe.

[OK] Site to Site IPSec + GRE = success, no problems.
[OK] IPSec remote access = success, no problems.
[NO] SSL VPN = remote users can successfully connect to all internal systems. Cannot pass traffic to the Internet.
Hardware:
Cisco 2811, Cisco IOS Software, 2800 Software (C2800NM-ADVIPSERVICESK9-M), Version 12.4(22)T5, RELEASE SOFTWARE (fc3) . Software: Cisco Any Connect Secure Mobility Version 3.1.01065
Single hub router terminating IPSec+GRE site to site, IPSec remote access, and SSLVPN remote access VPN services. All services currently configured and running successfully with the exception of the SSLVPN service. Remote users can initiate and successfully establish SSL VPN sessions. While established, connectivity to all internal systems/resources are successful. Only when the remote access client tries to connect to "Outside" Internet resources does traffic not pass successfully. Troubleshooting has pointed to a NAT related issue (I believe).
When connecting from a remote access workstation, utilizing IPSec remote access client (built-in Cisco IPSec client from Mac OS), the session establishes and the client works flawlessly. Examining the Cisco 2811 router, you see the /32 host route from the remote access session get installed, and you see the corresponding NAT translation entries created when the client accesses outside (Internet) resources. Appropriate configuration to implement "hair pinning" have been included to handle the in and right back out (with NAT translation) needed for remote clients to access the Internet.
Configured the 2811 for SSL VPN, and remote access clients can successfully connect and access all internal network resources. Examining the Cisco 2811, the /32 host route for the remote access client is installed, pointing to SSLVPN-VIF0 interface with a next hop of 0.0.0.0 When checking the NAT translation table, there are NO entries for the remote access client address created which leads me to believe the hair pinning/NAT function is not being invoked for SSLVPN clients.
Originally, the IPSec remote access VPN local pool was 10.0.100.0 /24. To keep from having to adjust the existing NAT translation, PBR Route-MAP for the hair pinning function - I took the 10.0.100./24 and broke it into a pair of /25 networks. Bottom half for the IPSec remote access VPN pool (10.0.100.0 /25); upper half for the SSL VPN pool (10.0.100.128 /25). By utilizing SSL VPN, is the traffic somehow bypassing the DIALER1 interface where both the crypto map (and more importantly: IP NAT OUTSIDE, and PBR configuration for the hair pinning function)? I cant explain why NAT translation entries are not being created for SSLVPN client sessions.
Cisco 2811 Configuration has been included. IPSec & SSL VPN Remote Access Sessions Captures (performed from same remote client) have been included.

I was previously using SDM for our Cisco 2811, and this past week installed CISCO Configuration Professional so I could have access to a bandwidth/traffic monitor.
I have successfully started the monitoring service and monitored traffic from within CCP, but it appears that if I turn off the computer I am using to monitor the traffic, it stops collecting data until I start CCP and the monitor up again.
Is there a way (maybe with IOS console commands) that I can have the monitor always running, so I can pull up, say, a week's worth of info at any time? Leaving the computer on all the time is not an option, and currently I have only a few days of data, then a big empty chunk, and then what I have collected since I started it back up today.

I have been trying to figure out a NAT issue on my 2811 and the inspect engine.I have 'ip inspect FW out' on my outside interface. If I turn it off, I also have to remove the access-list applying to inbound traffic on that same interface. Why is that? This whole thing centered around SIP registrations from devices on my LAN to my provider. The provieder is showing that I am registering from a high end port (1024 or something crazy). He said that it sounds like some type of SIP ALG or something on my router. For the life of me, I can't figure out what would be causing it. I am just using a standard route-map that points to the outside interface using 'overload'.

I've setup my Cisco ASA 5505 in transparent mode. I have a Cisco 1841 connecting to the ISP (DHCP client) and F0/0 for inside. The 1841 is the DHCP server. I have my ASA 5505 behind the 1841 in transparent mode (Vlan 1 for Outside and Vlan 1 for inside). The router config is good as when you connect a computer straight to the inside interface I get DHCP and can go to internet, no problems what so ever. But When you're trying to go through ASA isn't not working. if I add a ip any any statement to the access list it will work but having an "ip any any" in a access list is like having no firewall at all.

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.

I am experiencing a problem on a Catalyst 4510 (cat4500-ipbasek9-mz.122-53.SG.bin) with 802.1x configured. Client PCs are connected via a mini desktop switch to a Cat 4510 switched port in multi-auth mode. The configuration of the port follows:
!interface GigabitEthernet2/34 switchport mode access ip arp inspection limit rate 30 authentication host-mode multi-auth authentication port-control auto authentication periodic authentication timer reauthenticate server dot1x pae authenticator dot1x timeout tx-period 5 dot1x max-reauth-req 6 spanning-tree portfast ip verify source vlan dhcp-snoopingend
It happens from time to time that the Cat 4510 port stops passing traffic. Reconnecting the mini switch recovers the communication. Client PCs connected to the mini switch seem to be authorized at the moment when the problem occures. The RADIUS Termination-Action attribute is set to RADIUS-Request. The problem is not present if "authentication periodic" is disabled.

I'm trying to migrate old data from WCS 7.0 to Prime 1.2 ... I have already created the zip file from WCS and imported it into the defaultRepo on Prime. I see it in the directory when I do a show repository defaultRepo so I have confirmed that it is there. My issue is that it appears Prime 1.2.1.012 won't accept the cli command of ncs migrate.
how I can proceed with the migration? I haven't been able to find any similar command in the Prime CLI so at this point I'm lost as to where I should go from here. I really don't want to have to tell the customer they have to downgrade to Prime 1.1 in order for them to perserve their maps especially since the Deployment Guide for Prime Infrastructure states that it is possible to migrate date from WCS 7.0 to Prime 1.2 as shown below ...
Data Migration
#
Data can be migrated from WCS 7.0, NCS 1.1, or LMS 4.x. More details on migrating data from each of these applications are spelled out in the following sections.

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 installed a chained SSL cert on our anchor/guest 4402 a few years ago.We now have a need to replace the 4402 w/ a 5508, and I got everything configured, ready to go, except that darn cert.I can no longer locate the private key that was used to sign the original CSR.Is there any way to export the current cert from the 4402, so that I can import to the 5508? Or am I SOL?

I have done a WCS 7.0.220.0 to NCS migration prior to moving to Prime 1.2. I followed the instructions to export the WCS database via the export.bat all command and exported the database. However, when I import this zip fileto NCS there do not seem to be any of the original WCS templates. All the maps and AP details have migrated but no templates.
I have tried the export again and ploughed through the resultant zip file looking for anything that looks like template files but there is nothing immediately apparent that looks like templates.

Got an problem with LMS 3.2/Solaris.
See no devices both in DCR and RME, besides, in RME device counters (Normal/Pending/etc) are equal to current device count, but then you try to select them for any operation, you unsucceed - 0 device selected, no list of devices, unable to export, no ability to do anything.
Upgraded to 3.2 SP1, no change. Spend a lot of time digging through logs at /usr/adm/CSCOpx/logs, find no problems at all. Seems, that some database parts were corrupted.
I decided to reinstall LMS from the scratch, but to do so I need to export the DCR device data and credentials.
Database is alive (dbaccess.pl install going smoothly, then connection with user lmsdatafeed works and allows to connect and select data from any SQL tool), but this view is not enough for getting from the DCR both device data and credentials.
I have the DB password I set up during installation.
Is there any way to get data I need connecting to LMS database directly with some kind of sysdba SQL database user?

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'm moving from a 5505 to a 5520 and moving to a different location. I have a certificate on the 5505 that I want to export to the 5520.Can I export that key/certificate and import to the new ASA? Is there a problem since its a different location with a different IP ? (Domain name is the same, I moved the name on the DNS also)Do a have to re-do the signing process with the CA ?

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 am trying to export our network devices from ACS and I can't find out where it is exporting it. Under ACS 5.2 "Network ResourcesNetwork Devices and AAA Clients" you get the list of your network devices and at the bottom of the page there is an export button. When you click it you are given an option to password protect it which I didn't check the box and I pressed Start Export. The window flickers like it processed the request, but nothing happens. There isn't any pop-up to download the CSV. I have also tried setting up a software repo thinking it might just send it to that, but it didn't work either.

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.
