Morroring of serial interface....??

Hi..
Is it possible to mirror a WAN interface on the router.Means if the packets are coming on one serial interface can go to another mirrored serial interface at the same time. i need to analyze A WAN link with out putting the analyzer in between the WAN link. So i am thinking to mirror the another serial interface on the same router to see the packets.
Thanks.
SS

Hi,
no, to the best of my knowlege we do not have a span port like facility on the router.
You can not monitor a serial interface on another one. You must connect the sniffer into the serial line you need to monitor.
thanks...

Advice on constructing a test engine and formatting a spreadsheet test file to perform command line interface testing on a product through telnet or serial interface

Advice on constructing a test engine and formatting a spreadsheet test file to perform command line interface testing on a range of products through telnet or serial interface and output pass/fail results.

If I understand correctly, you want to do the following:
1. Create one or more tab-delimited files that specify a series of query strings (that LabVIEW will send to your products) and expected reply strings (that LabVIEW will look for in response to each query)
2. Run your LabVIEW program (the test engine) and have it execute one or more test scripts from file using either TCP/IP or serial communication to your units under test
3. Track how many of the queries are met with the expected response, and output an indication of whether each step passed or failed
If this is close to correct, then I've attached a sample test file and LabVIEW VI as an example; I chose the TCP/telnet method because it allowed me to use the ni.com Web site to simulate my tes
t hardware. If you happen to own the LabVIEW Internet Toolkit, there's a VI called "Telnet Play Script" in the Telnet palette that does something fairly similar using TCP. The same general model would also work for Serial communications.
Hope it helps,

Hello j. smith,
TestStand gives you the ability to create "sequence files" which are lists of tests to be run sequentially or in parallel. These tests can be written in any language: LabVIEW VIs, C/C++ DLLs, EXEs, ActiveX objects, .NET Assemblies, etc.
You can run your TestStand sequence files from a command-line prompt using the following syntax:
\bin\SeqEdit.exe" /quit -run
This will launch the TestStand Sequence Editor (and optionally prompt you for TestStand login information if you have this configured), run your sequence file, then exit.
If you're using the TestStand process model, it can output your results to a report file or database if you configure this. To use a TestStand process mo
del to execute your sequence file, use the following syntax:
\bin\SeqEdit.exe" /quit -runEntryPoint
Here's an example:
C:\>"C:\Program Files\National Instruments\TestStand 3.0\bin\SeqEdit.exe" /quit -runEntryPoint "Single Pass" "C:\Program Files\National Instruments\TestStand 3.0\Examples\Demo\C\computer.seq"
Note that multiple sequences and sequence files can be specified on the command line.
TestStand supports remote sequence execution using DCOM (Distributed COM), which is an east way to remotely execute tests. But as for running tests or commands through a telnet or serial interface, you would have need to check Windows documentation on how to execute command-line remotely like this.

What do I need to run a compiled vrsn of a serial interface ?

I compiled and successfully ran the compiled verson of an app. with a serial interface on a WIN2000 computer with the full LabVIEW development suite.
I installed the LabVIEW runtime engine only on a target computer (running WIN2000) and when I tried to run the app. got the following error -
arning -1073807202 occurred at an unidentified location.
Possible reasons:
VISA: (Hex 0xBFFF009E) A code library required by VISA could not be located or loaded.

You have to install NI-VISA.
It is possible to avoid this seperate install by including all of the required support files.
I believe there is a knowledge base article that lists all of the files that need to be included in your build.

Serial interfaces, ip vrf forwarding, and PBR with set vrf

I am doing some work with VRF-lite but I am having some trouble with serial interfaces. I have a PE router with a serial interface where I want to take incoming traffic and using policy-based routing send the traffic to the appropriate VRF. I want to assign the serial interface itself to be in one of those VRFs, not the global routing table. Eventually, I also want to overlap the VPNs/VRFs to send traffic going out the serial interface through the VRF assigned to the serial interface. Initially, it looks something like this:
ip vrf VRF1
rd 65000:3
route-target export 65000:3
ip vrf VRF2
rd 65000:18
route-target import 65000:3
ip route vrf VRF1 10.90.51.0 255.255.255.0 192.168.11.18
interface Serial0/0/0
ip vrf forwarding VRF1
ip address 192.168.11.17 255.255.255.252
router bgp 65000
no synchronization
bgp log-neighbor-changes
no auto-summary
address-family ipv4 vrf VRF1
redistribute static
no auto-summary
no synchronization
exit-address-family
ip access-list extended remote-source
permit ip 10.90.0.0 0.0.255.255 any
route-map SERIAL-INCOMING permit 100
match ip address remote-source
set vrf VRF2
But if I try to turn on the policy based routing at the serial interface, I get an error:
Router(conf)#interface Serial0/0/0
Router(config-if)#ip policy route-map SERIAL-INCOMING
% Can not apply route-map SERIAL-INCOMING to this interface
% Either remove 'set vrf' from route-map or unconfigure 'ip vrf forward'
I can sort of get around the problem by using an "ip vrf receive" instead of "ip vrf forward", but unfortunately, that leaves my Serial interface in the global table which isn't what I wanted.
What troubles me is that I can do this without any problems on an Ethernet interface. Are there any known issues with "ip vrf forward" and using PBR and "set vrf" on Serial interfaces, or have I configured something wrong?
If I stick with the "ip vrf receive", how can I force the physical Serial interface into the appropriate VRF?
Thanks.

Upon further investigation....
The serial interface issue was a red herring. It just so happens that every other time I've done this it has been on a flavor of 12.2x on a 6500/7600 where this feature is supported. The only systems I have with Serial interfaces are 1841s.
The problem with the 1841 is that most of the code revisions out there do not support this feature. It was only added to the regular code train with the recent release of 12.2(24)T. I tested with 12.2(24)T1 and you are now able to use "ip vrf forwarding" on all interfaces along with a PBR route-map that uses the "set vrf" option.
Thanks, Laurent, for pointing me towards the TAC on this.

Third Party Bluetooth Serial Interface

Hi,
I have a third party EEG headbox with bluetooth connectivity using serial interface. I did the followings:
From Bluetooth, added the device that was successful. Furhtermore, two unidirectional ports were added to the device i.e. COM3 (incoming) and CoM4 (outgoing) - VISA
The device is successfully accepting the commands i sent with a beep acknowledgement.
The followings are the issues.
The device is not responsing with any data i.e. nothing coming to pc/ laptop because of the device is using two unidicrectional COMs.
Query:
How can i assign the one COM to the device so that i can receive the bytes as well.
Regards,
Abdul

How to upgrade IP/KVM Console AF620A via serial interface?

Hi
I've got a "HP 1x1Ex8 KVM IP Console Switch G2 with Virtual Media CAC Software - AF620A" which is not booting correctly anymore.
Symptoms:
- blank screen
- status leds constantly blinking
- serial output hangs after "Booting:1.2.10.15038"
Hooking up to the serial interface, the terminal gives me, that the current version as well as the alternate version of the used firmware is 1.2.10.15038. As far as I was able to find out, I should upgrade to the latest firmware in order to get rid of the problem and make the device usable again.
My problem is, that I don't know how to upgrade the firmware via the serial console, knowing that the device is not booting up the firmware.
Yes, I've done a factory reset as well as a configuration reset. No change ...
I've opened up the case to see if there is any hardware reset button, but there is none. The only thing I found is a 4pin header labeled "HDR2" but neither the user guide not the technical guide gives any details about the interior of the device (of course not ...).
Has anyone had the same problem with this or any similar device?
Or does anyone has a good advice what I could try to revive the KVM?
greetings

I finally got through the helpline, but as my device is out of warranty, the official solution for my problem is to buy a new device!
Ending is better than mending ... welcome our the brave new world ...

C-Series Module NI 9871, 4-Port, RS485/422 Serial Interface

I have a question regarding the C-Series Module NI 9871, 4-Port, RS485/422 Serial Interface.
I need to find out how it recovers the data from the link. I need to compare it with 8b/10b encoding.
Does anyone know what UARTs are used or how the data is recovered.
Thanks
John Lee

Hi John,
I have had a look into this and I cannot find any specific information on the Transciever or UART. However I have come across an example using the 9871 with processing on a cRIO FPGA.
To find this example open up Labview » go to Help » Find Examples » Search for 9871 and open up NI-987x Serial Loopback.lvproj.
Hopefully this should give you a good start. Once your serial data is passed onto the FPGA you can then decode the 8b/10b within the FPGA code.

Communication through RS232c serial interface using labview

i am trying to communicate with a device through RS232c serial interface using labview 6.1....i have tried to run the example "Serial communication.vi" provided in 6.1 and it doesnt work....do i need any special hardware or do i need to configure my hardware to communicate through RS232c...
thanks in advance
shri

Seems like I placed a small (maybe 30ms) delay at the end of the serialcommunications.vi structure.. for some reason my PC didn't like running as fast as it tried to go. Also look into the actual serial communication.vi and open the vi's inside it - check that the port setting (0 or 1) are ok, the baud rate (probably 9600) are ok. I'm running with only three wires in my application, TX, RX and Common. The PC may need to be rebooted to enable the com port - or use device manager and see if it says the com ports 0 and 1 are both OK..
Try buildinga loopback plug with TX to RX, RX to TX, and Common to Common and see if hyperterminal (or other serial communications program works - there is also Loopback.VI in the NI library somewhere that can be used. Good Luck!! Dave

Mapping asynchronous to a serial interface

Hello everybody,
i got an ISR3845 with PVDM2 inside. The goal is to map a incoming call depending on the caller number to a dedicated serial interface.
How do i configure a static mapping from a asynchronous to a dedicated serial interface ?
Thank you very much for your support

I'm seeing a high runt count on my serial interfaces after upgrading to 12.

I'm seeing a high runt count on my serial interfaces after upgrading to 12.2(37).
I was looking for information on what changed in 12.2(37)and some more detailed information on runts.
I know that runts are smaller than the medium's minimum packet size. But I want more specific information and I can not find meaningfull information.
Any Ideas

On a serial interface I would contribute the runts to a timing problem which is not an easy problem to isolate esp. with a telco. Even though there may be no CRC or Frame errors.

Ip wccp redirection direction at ethernet and serial interface.

hi all.
commonly, we use 'ip wccp 62 redirect in' at serial interface to grap packet for sending cisco waas.
but some document is mentioned that 'ip wccp 62 redirect out' ethernet interface facing data center side.
I guess, there is same meaning, I think that It's better to apply 'ip wccp 62 redirect in' at serial interface due to router performance. Right?
Can you explain clarify for me?
Thank you.

You are correct redirect in is less cpu intensive as compared to redirect out
WCCP redirection can be configured to occur as packets enter a router or switch interface (inbound, or ingress, redirection) or as they are beginning to leave a router or switch interface (outbound, or egress, redirection).
* Inbound redirection - the WCCP process inspects traffic to find packets that should be optimized before the packets enter the router or switch forwarding/routing selection process. Inbound redirection is less CPU intensive than outbound redirection (when using process or other SW based switching).
* Outbound redirection - the WCCP process inspects traffic to find packets that should be optimized as the packets are ready to leave a router or switch interface, after the packet has gone through the router or switch forwarding/routing selecting process. Outbound redirection is more CPU intensive than inbound redirection.
Thanks

How is serial interfacing done in labview

how is serial interfacing done in labview

well i would like to send a command A0H to digital video recorder and recieve acknowledgements at serial port. in order to recieve i am calling the visa read function. but i am recieving no response of acknowledgement string.
well i am able to send eject command (2AH)successfully, but i am not recieving any response string from digital video recorder
i am using digital video recorder DSR-20/20P.
moreover when i call read vi for time code request, i get error message (-1073807339). may be the read function i am calling is not the right one?
i am sending my source code. can u correct it please.

E1 link comes up only after shut / no shut of serial interface

Hi all,
I have a problem with a E1 link connected to a 2811 with a NM-1CE1T1-PRI (running c2800nm-advsecurityk9-mz.123-11.T10.bin). If I plug in the cable to the router, Layer 2 will not come up. I have to shut/no shut the serial interface to get it work.
I do also get the following error message:
*Sep 19 15:44:08: ISDN Se1/0:15 **ERROR**: service_queue_from_physical_layer: controller state isn't up, and got ISDN_PH_ACT_IND
Does anyone know what this means? I couldn't find any information nor a bug for this behaviour.
Many thanks,
Steffen

Hi Steffen,
I'm sorry, because it's not to give you an anser but to also to ask a question about the problem i face in the same controller NM-1CE1T1-PRI runnning in cisco3725.
when i try to configure the channel-group, the routeur restar and generat this error:
%Error opening tftp://255.255.255.255/cisconet.cfg (Timed out)
*Mar 1 00:03:31.027: %SYS-4-CONFIG_RESOLVE_FAILURE: System config parse from (t

Also when i lunch this commande:
cisco_alc3(config)#card type e1 2
it gives this error:
