  • Option 156 Question

    I have a client who just configured Option 156 on their network so the phones would pull a DHCP on VLAN 2. Everything is working fine with the phones but he's telling me that other devices are now pulling IP's from VLAN 2 as well.

    Can anyone think of why that'd be happening? Thanks!

    How are the switch ports configured for the other devices getting VLAN 2 ips?

      Sounds like the PoE switch is not configured properly, what kind of switch are you using?

        They're Dell switches I believe. They have an IT admin but he isn't that knowledgeable on VLANs so he asked for some help.

        I think pointing him in the direction of checking the PoE's could be a good start. Thanks!

          Are both vlans on all ports and the ports you add to the voice vlan should be tagged. Also enable ip forwarding.
