    VLan using LLDP

    networknewbie New Member

      As my name suggests, I am new to this VLAN configuration. I currently have 2 networks in my place of business. I am needing to connect both of them to one switch. and have the Switch handle DHCP. The Switch has to determine if it is VOIP or another device and assign the IP Address appropriately.

      My Current Configuration looks as follows

      Tell me what I am missing, why it is not working to assign phones to VLAN 10 and Other Devices to VLAN1? How do I fix it? Why is the DHCP Service not assigned the correct IP Address to devices?

       

      Thanks in advance for the assistance.

          I forgot to mention that the Phones and computers are getting the same IP address even when I program he phones with a different VLAN. they appear to be taking on what ever IP is Plugged into Port 48 on the switch.

            In my experience, this is a LLDP issue.   You may have to enable LLDP on the phones.  The phones rely on LLDP in order to get VLAN, CoS/DSCP information from the switch.  It should still work with manual VLAN configured provide that VLAN configured on the phone is available on the switch port.  On many IP phones, if it does not received a DHCP address from the tagged VLAN, it will fall back to untagged and send out another DHCP request.  This lands the phone on the native VLAN of the switchport.  That sounds more like what's going on in your situation.

             

            Referencing interface gigabit-switchport 0/38 (randomly picked):

            This looks correct here, however, I would include cos and dscp values in the statement, unless you are good with a CoS value of 5 and DSCP value of 46.  Those are the defaults for a voice port on the NetVanta line.

            Being that this is correct (Not 100% sure about port-security), it must be that LLDP-MED is not happening, or the phones are not capable of it.  My first step would be to verify that LLDP is enabled on the phone.  I've run into many cases with Polycomm phones where it is not enabled.
