Using CDP to create the network topology diagram

Hi all

I'm a beginning network specialist and just thought I would throw this question and see if I can get some answers.  Well, I want to know how I can use CDP to find out our network topology so I can create diagrams and Visio diagrams, or if you know any free network discovery programs out there that can help?  Hey well any comments will be appreciated so thanks in advance and I look forward to hear something!

When you run 'sh cdp neighbors' it shows you all the devices connected directly. If you then "sh cdp neighbor detail" for each entry it will show the IP address of the connected device. You can then connect to this and do the same thing all the way throiugh your network.

I think that the COP may be useful for this, but you're relying on the CDP running on all devices. Sometimes it has been disabled for security reasons one must always be aware that there may be devices that do not display.

As mentioned SNMP is another alternative, but still once, this assumes that SNMP has been put in place the device esch.

So just be aware that you can not always get the full picture, but a combination of--

(1) CDP

(2) SNMP

(3) running the determination of route router hops show but not L2 switch.

You should get most of the information. Also, be aware that the internal firewall tend to dirty such things as well.

  • Windows cannot create the network map. Responses of the other devices on the network are delayed or on the network, there is a router incapatible

    Original title: no network card
    I installed a NETGEAR N300 Wireless USB Adapter on my computer which is a desk top Dell 64-bit running Windows 7 Edition Home Premium. There are five computers on my network. Two of the others use the same model of NETGEAR wireless USB adapt. I removed the Ethernet cable after the installation of the wireless adapter. I can say that the new wireless adapter works fine. When I tried to map the network I got the same message that appears in some of these problems: "Windows cannot create the network map. Responses of the other devices on the network are delayed or there is a router on the network incapatible". I have restarted this computer in SafeMode as suggested in the above problems. I tried other things like disabling the wired connection has always existed for the cable. No effect. Then I tried mapping the network on the other computers. All failed with the same message. All the other four computers are 32-bit. Three of these computers are also running Windows 7 Home Premium. They are the best desktop computers. The other computer is a Windows 7 Starter netbook running. It is the 32-bit computer, always using a cable. That will be replaced with the same wireless adapter model NETGEAR. Anyone know how to fix this or is this a bug? It would be nice of the network software of Windows 7 has worked as it is supposed to. TO.

    I went the last wired wireless computer and the problem disappeared. The five computers can view the map now without any problems.

    I can't find that any information how to do this from a windows machine (now only available) of the old system had the lion as I was told and when trying to install lion line or wireless it says it isn't available now so the machine is stuck without an operating system.

    If you are anywhere near an Apple Store, I would suggest bringing your MBP to and asking to help. For USB, you need to partition and format to allow to boot on a Mac, what Windows can not do. Then either create a bootable installer or install OS X on USB and then copy the installer it, boot from it and run the installer with the SSD as a target.

    Hi everyone I can't seem to fix this strange problem.

    I can't use windows Explorer or the network drive mapping to access my NAS drive more.
    I am running windows 7 Professional 32-bit on my PC, and until about a week ago she accessed from my PC very well.

    The location could not be reached and have not been able to run since said today that I went to update it and the drive mapped. I'm at my wits end.

    I can access the internet.
    I have a windows XP PC in the House who can always connect to my fine NAS drive (even if it's not mine).
    I PING the NAS drive.
    The NAS drive will do the same if connected via cable or by wireless.

    UPDATE: after the implementation of a shared folder on a Windows XP computer on the same network I am also unable to acsess the part of my PC. So I can assume that I can't browse all share folders or NAS drives on my local network.

    Is the same for the box:

  • problem of traffic flow with tunnel created the network with a tunnel to a VPN concentrator

    Hi, I worked with Cisco and the seller for 2 weeks on this.II am hoping that what we are witnessing will ring a Bell with someone.

    Some basic information:

    I work at a seller who needs from one site to the other tunnel.  There are currently 1 site to another with the seller using a Juniper SSG, which works without incident in my system.  I'm transitioning to routers Cisco 2811 and put in place a new tunnel with the seller for the 2800 uses a different public ip address in my address range.  So my network has 2 tunnels with the provider that uses a Cisco VPN concentrator.  The hosts behind the tunnel use 20x.x.x.x public IP addresses.

    My Cisco router will create a tunnel, but I can't not to hosts on the network of the provider through the Cisco 2811, but I can't get through the tunnel of Juniper.  The seller sees my packages and provider host meets them and sends them to the tunnel.  They never reach the external interface on my Cisco router.

    I'm from the external interface so that my endpoint and the peers are the same IP address.  (note, I tried to do a static NAT and have an address of tunnel and my different host to the same result.)  Cisco has confirmed that I do have 2 addresses different and this configuration was a success with the creation of another successful tunnels toa different network.)

    I tested this configuration on a network of transit area before moving the router to the production network and my Cisco 2811 has managed to create the tunnel and ping the inside host.  Once we moved the router at camp, we can no longer ping on the host behind the seller tunnel.   The seller assured me that the tunnel setting is exactly the same, and he sees his host to send traffic to the tunnel.  The seller seems well versed with the VPN concentrator and manages connections for many customers successfully.

    The seller has a second VPN concentrator on a separate network and I can connect to this VPN concentrator with success of the Cisco 2811 who is having problems with the hub, which has also a tunnel with Gin.

    Here is what we have done so far:

    (1) confirm the config with the help of Cisco 2811.  The tunnel is up.  SH cyrpto ipa wristwatch tunnel upward.
    (2) turn on Nat - T side of the tunnel VPN landscapers
    (3) confirm that the traffic flows properly a tunnel on another network (which would indicate that the Cisco config is ok)
    (4) successfully, tunnel and reach a different configuration hosting
    (5) to confirm all the settings of tunnel with the seller
    (6) the seller confirmed that his side host has no way and that it points to the default gateway
    (7) to rebuild the tunnel from scratch
    8) confirm with our ISP that no way divert traffic elsewhere.  My gateway lSP sees my directly connected external address.
    (9) confirm that the ACL matches with the seller
    (10) I can't get the Juniper because he is in production and in constant use

    Is there a known issue with the help of a VPN concentrator to connect to 2 tunnels on the same 28 network range?

    Options or ideas are welcome.  I had countless sessions with Cisco webex, but do not have access to the hub of the seller.  I can forward suggestions.

  • Using multiple computers on the network

    I received the J6480 for Christmas and that you install wireless to my desktop computer... everything seems to work great so far.  Should what steps I follow in order to use the J6480 with my 2 laptops?  The office is Vista, the two XP laptops.

    I'm not too familiar with the concept of networking and I know that there is a way for me to connect laptops with the office but is there a way to network directly laptops of the printer?  My apologies in advance if I don't use good terminology or sound like a fool in plain.

    Just run the installation with a CD-ROM on other computers.  The SW will detect that the printer is on the network and simply install the drivers for you.

    A few tips:

    1. Pay attention to all warnings when installing on the firewall SW running on your laptop.  In general, the firewall must be configured to allow the printer driver to function.
    2. Consider defining a reservation in DHCP for the J6480 on your wireless router.  This ensures that your printer will always get the same IP address from the router without wire-, which prevents some problems with certain features of the printer.  Just look for the configuration of your wireless router DHCP reservation.

  • Cannot create the network location in my computer

    I can't create a network location in my computer. I open my computer and right click on an open area and enter the ftp://ftp.irvinerunningclub.co.uk location but get the error message "the folder you entered does not appear to be valid" I have another computer with the same version of windows 7 (home premium) that allows me to create this place without problem.

    Hi Finlay,

    I understand that when you try to create a network location, you get an error.

    The error message you get usually occurs when Windows try to check the subfolders of the parent and parent. If the parent folder is not configured for WebDAV, the connection attempt fails.

  • What ODI protocol uses to communicate over the network?

    We need to open ports in the firewall to allow the ODI to connect to another instance, but we want it open only for the protocol used by ODI. It would be something like SQLNet or HTTP.

    In general, communication purposes with an agent of the ODI for invocation (i.e. perform scenarios etc.) is performed via the HTTP protocol on port defined by the user, as far as I know - TCP port 20910 is often used. If the communication with the agent of ODI is protected with SSL / TLS, then the initial communication would take place over HTTP on port defined by the user in front of an encrypted tunnel is set up by using the SSL / TLS protocol.

    Database connectivity is also at the level of the network as you say properly and according to the particular database that you are using a different application level protocol will be used by the JDBC driver. For example, database connections Oracle would use the TNS (the TCP port default 1521) Protocol while MS SQL uses the Protocol (TCP port 1433 by default) TDS, but these ports can be customized. If you use tools such as SCP in ODI while you need to open ports between the agent and the target computers so that for example you can access SSH on the target (TCP 22 for SSH default port) machine and so on.

    What this really means to however, it is exactly that you need to open TCP ports would depend on what tools you use in ODI and what technologies are, you connect from / to. It depends also to some extent how smart is your firewall and if it can detect the level protocols such as HTTP application with inspection packages rather than having to allows you to configure ports specific TCP rather than application-level protocols, for example TCP 20910 port.

  • Use BeehiveOnline to create the internal/external email address

    I need to have an e-mail alias which will reach internal and external members. I used to be able to use the APS to create an e-mail alias and add two internal members and external to Oracle. Now I thought I should use BeehiveOnline.

    I created a group that includes an external member. How can I view the email address for the Group (if it was created automatically when I created the Group) or create an e-mail alias which sends e-mail to each Member of the Group?

    Hello

    If you have created a group on BeehiveOnline it is, by default, a distribution list with everyone in it - internal and external.

    The recommendation is to create a group, but unless you need the workspace to select No for the "required default Workspace:" option.

    Once the group is created there will be an equivalent of [email protected] e-mail address so if your group was called "Acme" your email address to send to the members of the Group would be "[email protected]".

  • Best practices using clusters to create the queue/notifier/bundles?

    I'm in a block diagram, a queue, the notifier and several instances of cluster of bundle

    that all use the same data structure.   There is a typedef of cluster for the data structure.

    Of course, each of these objects (define the queue, set notifier, bundle)

    you want to know how do you define the cluster.

    What is considered best practices?

    (1) create a dummy instance of the cluster across data structure

    definition is necessary (and hide all on the public Service)

    (2) create only one instance and son at all places, it is necessary

    But there is no stream on this thread: it's only the cluster * definition *.

    which is used, so this seems to clutter the comic.

    (3) create only one instance of the cluster control and use local variables

    everywhere else the definition of cluster is required.  It's _value_ is never

    assigned or given read-so no problem with race conditions.

    (4) another way?

    If you were to clean up someone else's code, how do you expect

    See this Treaty?

    It occurred to me during this writing that here where I

    "unbundle...... code bundle" I could wire the original beam to the

    the two "unbundle" and "bundle" - but that would be too complicated

    and the size of the comics with useless thread?

    Thank you and best regards,

    -- J.

    Hi Jeff,

    I think that this question is about "sharing" the typedef and not how share data (?)  If the cluster control is registered as a typedef (or a strict typedef) but NOT SIMPLY as a CONTROL, then when a Diagram-constant of the typedef is created, it will be updated when you update the .ctl typedef!  (and there is no FP control to hide )  Of course if the typdef is already available "close" if necessary, you will be able to use instead - save a spacer of diagram.

    See you soon.
