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

[AntonyZEL]

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

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...
