    show iparp provide me all the MAC and users ip which are connected that time but I just need some limited users MAC ip until i need to create a big data .

    Correct, that is why I added the filter "| include " Mac you are interested in " " Show iparp | include "Mac"

    You can also leave off the "| include" and just do 'show iparp

    Hi Mateusz
    To get IP and corresponding MAC reflected in the output of show iparp; you need to make that (another vlan) as L3 on switch; Or else you will be able to see the MAC addresses only (using show fdb).

    Thanks for quick reply.

    @Tomasz - I just enabled nodealias on my switch and tried to display table as follow:
    show nodealias. Here's output:

    I'm interested in port 1:39 which shows no aliases. Anything missing?

    "show nodealias" shows the config for nodealias.

    If you'd like to check port details use "show nodealias ports all" or for one port "show nodealias ports 1:39"


  • 11.  RE: How to view IP address with known MAC address in EXOS

    Posted 10-26-2018 10:43
    You can also try "show nodealias mac


  • 12.  RE: How to view IP address with known MAC address in EXOS

    Posted 10-26-2018 10:46
    @Ronald - that clarifies much but still can't see any IP/MAC while giving:

    show nodealias port 1:39

    He'll get a chance to ask us a proper question when I un-suspend him on Monday.

    Hi folks,

    Let my hook up to this topic.
    I've tried above commands but those will only show MAC's for VLAN where the switch is.

    If I issue show iparp | include "MAC" it shows nothing. When I issue just show iparp it gives me MAC's of other switches which are in the same mgmt VLAN.
    The question is: How can I get IP of device in another VLAN (directly connected to this specific switch).

    Ok, Wagner. You can try this again if you'd like.

    With that attitude, there aren't many things that are likely to work for you.
    Another job maybe 🙂

    Wow, perhaps you should rather herd sheep or sth.

    Posted 09-28-2018 17:02
    I'm wonder if he has XOS switches? If he can fix his attitude and provide a bit of information maybe we can get him on the right track.

    Posted 10-26-2018 09:52
    Hi Mateusz,

    If you have EXOS device with version that has "enable nodealias port all" you should try this for L2 (non-routing) switch. It will bind MAC, IP and port in single table you can display.

    Hope that helps,
    Tomasz


  • 20.  RE: How to view IP address with known MAC address in EXOS

    Posted 10-26-2018 10:46
    please do a "show ports 1:39 no" and post the output.

    You'd see in the "show nodealias" output that you've posted that the port 1:39 has no entry for nodealias = 1:39(0/157) = the 0 = no entry, other ports are fine

    With that attitude, there aren't many things that are likely to work for you. If you have trouble figuring out a command, provide us with some useful information and ask a proper question instead of spouting off profanity to others for helping someone else in a nearly 3 year old thread.

    Edit: You can come back and try again on Monday.
