Hello, 

 

My two phones don't get IP addresses from DHCP Vlan 66, could you tell me why ? The GUI of the IP phones print "Configuring IP".

Hello,

 

in short, everything was misconfigured: the access ports, the trunk port, the subinterface on the router, the switch SVI, and the ephone mac addresses. I have revised the file, review the configurations...

Hi

 Is it PacketTracer? can you add the pkt file in here?

Hello,

 

there is one crucial mistake in your configuration, change that and check if it works then:

 

-->  --> ip source-address 10.66.0.0 port 2000

 

needs to be:

 

--> --> ip source-address 10.66.0.1 port 2000

Hello, 

 

Thank you for your replies, I think it's a phone MAC Adress problem or wrong switch port config ?... I would like it to be on the VLAN 66.
