Configure voice vlan without using cmd "voice vlan mac-address..."

  • 1.  Configure voice vlan without using cmd "voice vlan mac-address..."

    Posted Dec 05, 2020 02:20 AM

    Hello,

    I would like to configure switches in order to plug Cisco phones (7841 for ex) using only LLDP MED without knowing the mac address of phones. I have tried but I have to put the line below in order to make phones working.

     

     

    # voice vlan mac-address xxxx-xxxx-xxxx mask ffff-ff00-0000 description Phones

     

     

    Is there a way to configure ports switch with voice vlan without this line ?
     
    Many thanks,
    Regards,
    Antony
     

    #mac-adress
    #Voice
    #LLDPMED
    #switches
    #VLAN

    Hello @AntonyZEL !

    AFAIK you need that command, but if your target is to avoid MAC address administration burden you may use two general records that will cover all Cisco phones:

    voice vlan mac-address 0000-0000-0000 mask ff00-0000-0000
    voice vlan mac-address 8000-0000-0000 mask ff00-0000-0000

    Hope this helps!

    Many thanks for your help.
    2 more questions :
    - will it covers all Cisco phones because some Cisco mac range begin by 04...,06, A4 etc... Do I need to add other range ?
    - will it be working if I plug computer (with some mac beginning by 00) using data vlan behind Cisco phones ?


    Thanks you,

    Hi @AntonyZEL !

    I'm afraid I forgot to ask you the most important question - what is the switch model? I need to know if it's running Comware 5 or 7 as configuration is quite different...
