Cisco ip to the mac address of a device?

What command I can run in CLI, to get a mac address that is associated with a given ip address?

Context: In order to access wifi, users will have to go through web authentication. To submit their credentials, we are able to see their ip address. We want router cli api query or something, to find a mac based on the IP address.

Pointers?

Yes, it's a very simple way to get it, in the past you could not even do this & Cisco added this feature only from code 7.5.x.

If you cannot do a lot of filtering on, hope that Cisco will further improve it. If you need to live with these limitations at the moment :)

  • Wireless devices shows the MAC address for 1 device that does not have an IP address

    I am tracking down each device connected to my router nighthawk and I identified everyone except this. There is a device of Wirelsss appears when I connect to the router that does NOT have an IP address but it has a MAC address. An interesting point is that the router device itself has a number of MAC that is not anywhere in the list of devices. Any ideas what this could be? I have an Extneder range wireless attached Nighthawk also but I already idenfified his IP address and Mac address.

  • How to get the Mac address of a virtual machine?

    Hello world...

    I need help to get the MAC address of a virtual computer, I'm stuck in it.

    Thank you

    Here's a vSphere SDK for Perl script that extracts the MAC addresses for all your virtual machines - http://communities.vmware.com/docs/DOC-10490

    You should be able to take it and translate it into any language vSphere SDK you plan to use. Basically you'll be listing through virtual hardware for the virtual machine to search for devices of type VirtualEthernetCard and then retrieve the MAC address of each device.

  • Obtained the MAC address, IP address

    I have a piece of 'unusual' of devices connected to the network that seems to have lost its IP address during a blackout, and have either assigned a new via DHCP or returned to a default value.

    Unfortunately, I don't know what this IP address. I have its MAC address, and I need to find its IP address so that I can reschedule.

    It is a Cat5 TPC/IP based ethernet running voice and data on Cisco. I'm not familiar with the structure of the network and it does not seem anything more than basic network management tools installed. The local administrator apparently normally addresses DHCP by checking newspapers etc. manually. I am not an expert in.

    In the simplest terms, how should I get the IP address of this device, based on its only MAC address.


  • where can I find the mac address for Airport Extreme

    just bought a new Airport Extreme 802.11ac and I don't know here to find the MAC ADDRESS. Can someone tell me where to look. I have the model and serial number, but can not find the MAC ADDRESS.

    Is the AirPort Extreme, set up and operation right now... even if he could not have an Internet connection?

    If Yes... Open the AirPort on your Mac utility... (Finder > Applications > utilities > AirPort Utility)

    Hold down the option key on your Mac when you double-click on the image of the AirPort Extreme

    The next page will display a summary of the parameters

    The AirPort Extreme has done 3 different MAC addresses... Ethernet, WiFi 2.4 GHz and 5 GHz WiFi.   If your AirPort Extreme is connected to a modem by an Ethernet cable, then the Ethernet ID is the MAC address.

    If the AirPort Extreme has not set up yet at all...

    Open AirPort Utility as above, and then click the file menu in the upper left corner of the screen next to the Apple icon

    Click on configure the other

    For address, enter 10.0.1.1

    A password is normally not necessary, but if you are prompted for a password, use the word

    public

    Click OK, the settings summary page is displayed.  In most cases, given that the AirPort Extreme connects to a modem via an Ethernet connection, you want to use the Ethernet ID as the MAC address.

    If you are still experiencing difficulties, you have 90 days of support Apple phone. Call them and maybe they can explain why that should be a very simple task is so difficult.

  • The printer receives do not all data. It is caused by the MAC address filtering.

    How can I solve this problem.

    The printer attempted to join the network but does not receive any data.  This may be caused by the MAC address filtering. If MAC address filtering is enabled and you want to keep enabled, add the MAC address of your printer in the list of devices allowed for your wireless access point or router before continuing.

  • Can I get the MAC address for my lost iPad?

    I think I left my iPad Pro in the street today while loading and led away.  When I realized it, I rolled back, but he had disappeared.

    It's a Wifi model only, so find my iPhone will not be much help.  However, my local ISP is a service where you can register the MAC address of the device and it uses one of the many public access tasks automatically, then in this case I find my iPhone could help.

    Is there a way to determine MAC address the iPad when I don't?  Perhaps through iTunes?  I checked the box, but only the serial number is in the list.

  • Find the MAC address of the host remotely logged on to a domain

    Hello

    I work in an environment where we use the thin client (Sun ray DTU) to connect to sessions. The sessions are communicated through solaris servers, and windows servers. Explain further, the thin client connects user to the layers of solaris that connects to windows to allow the user a session window. Window servers are in a private domain. I work as a security consultant in the business and use a management software log for surveillance of newspapers. I collect the windows logs via the software (Application, security, installation, System) agent. My question is, HOW do I GET the MAC ADDRESS OF THE THIN CLIENTS? I have the IP address, username etc but not the mac address of the workstation. However - the TASK MANAGER and REMOTE DESKTOP SERVICES MANAGER give the MAC address in the CLIENT NAME. I raised the level of the event log to ' 5 "(through registry), enabled all policies audit with categories and subcategories as well but always without success."

  • Analyze the Mac address with the regular expression matching

    Hello world

    I have a problem with the function of regular expression matching,

    I try to analyse the response both a query arp - a 192.168.0.15 to retrieve the MAC address of the remote IP address, I used the following regular expression: ^ ([0-9a-fA-F]{2}[:-]){5}([0-9a-fA-F]{2})$

    I wonder why should I do a subset of the first string to extract only the part of the MAC address. The regular Expression function is not able to recognize the regular expression directly in the middle of a string?

    I only works when I extracted the subset of tring right as in the picture below.

    Thanks for your replies.

    Get rid of the "^" at the beginning of your regular expression. You are ordering him to find the model at the beginning of the string.
