  • 1.  multiple TFTP servers?

    Posted Jan 08, 2009 04:05 AM
    Situation:

    We use Avaya VOIP phones on our network.

    We have multiple DHCP servers, however the one that matters right now is the one in my Office (~300+ PCs / maybe 50-100 VOIP phones)

    on the local DHCP server, which is also the server that DS is installed on, we also have the reflection server, which is what runs the TFTP daemon for the VOIP phones (for firmware upgrades mainly)

    So when the reflection server is running, if I boot up a PC it gives me the TFTP: File not found error.

    And if I stop the reflection server and let the PXE server run, I get the same error on the Phones when they boot up.


    IS there anyway to get these two to play nice?

    My first thought was to move the DS & PXE server off of the DHCP server, but even then, it seems like you would only be able to have one TFTP server running at a time on any network segment (is that right?)


    Thanks

    Chris

    Generally speaking, VoIP devices should usually get their own VLAN or subnet (especially for QOS). If that is the case, you would just modify each DHCP scope that serves up the VoIP device IPs to point to a specific TFTP server (we do that here with our Cisco IP phones). Then every other VLAN or subnet that does not have this defined would get routed to your PXE server.
