  • 1.  Polycom C60 phones and tagged vlans

    Posted Apr 14, 2025 10:16 AM

    Hi,

    I have a Polycom C60 phone and am using macauth  to  connect it to our network.I then use the device fingerprint  to pass back a vlan-name-tagged vlan name but at this point te phone  doesnt obtain an ip address. If I pass bacl a vlan-name  seting i.e. it uses an untagged vlan everything works just fine. We currently have lldp disabled on the phone so its not going to use that to  push the phone to any configured  voice vlan on the switch.

    Is there a way of telling the phone the default vlan is going to be a tagged one ?

    You can use Radius attributes to tell the switch the VLAN name or VLAN ID. You can also specify whether the VLAN should be tagged or untagged.
    You cannot communicate with the end device via Radius.

    Have you looked in the Polycom documentation how to change the VLAN to tagged?

    Hi,
    [polyocm doc not too helpful. Doesnt seem to be a way of telling phone to use a tagged vlan directly.

    However,

    Initial issue was there were 2 voice vlans on the switch, an old legacy one and the one we want to use.

    I deleted the old legacy one and enabled lldp on the phone. So

    Phone macauths
    Cppm says use this tagged vlan
    Phone uses lldp to find voice vlan
    Phone uses defined voice vlan … which is the one CPPM auth’d it into
    Phone gets an ip address and works
