Tomato shibby - Device List

    Hello,

    is it possible to see under Device list what is connected to the switch?

    I am using switch with my RT-N66U since there is no enough ports for my needs.

    When my Printer is connected to switch (not directly to the router) i am unable to see local IP under Device list?

    Thanks

    If your printer is using DHCP then the printer should show up under the Device List. If you give the printer a static IP allocation via DHCP, it will also show up. However if your printer is manually configured to have a static IP (i.e. no DHCP), it will not show up.

    Thank you for answer.

    It is set to static ip actually, so, that is the reason :mad:

    So, there is no way to make this work (have all stuff listed under device list?)

    There is no way to make this work as long as the printer has a manually-assigned IP address (i.e. is not using DHCP). This is how Ethernet and IP works.

    i see, i am still little bit confused though.

    I have static IPs set to most of my hardware and it visible under device list, but, nothing that is connected to linksys switch :rolleyes:

    Is "most of your hardware" statically assigned via DHCP or manually assigned on each system (i.e. no DHCP)?

    If the latter: then the reason has to do with packets being forwarded through the router, meaning the router is able to see ARP announcements and cache the MAC address of the systems attempting to use the router as a gateway. This is part of Ethernet protocol (layer 2), which sits "atop" (as in "comes first") the IP protocol (layer 3).

    If you get on the router and issue the command ping -c 3 {ipofprinter} in either Tools -> System, or via the command-line (telnet or ssh) on the router, does the printer then show up in Device List?

    @Daky.
    You are not going to see the printer ip on the switch device list - even though it has static ip. The printer static ip has to be saved on the switch settings for this to happen.
