Trouble with Voice Vlan and dhcp

I have a brocade icx 6450 with the following config. The pc's are connected directly to the phones.

I have port 1/1/48 going into another switch which is has teh dhcp server for the data network and port 1/2/1 going to another switch which has teh dhcp server for the voip network.

Now the pc's get the dhcp requests fine but the phones do not work. PLease tell me what I am doing wrong.

Re: Trouble with Voice Vlan and dhcp

Did you enable LLDP? 

 

LLDP is enabled by default on individual ports. However, to run LLDP, you must first enable it on a global basis (on the entire device). To enable LLDP globally, enter the following command at the global CONFIG level of the CLI.

 

Brocade(config)#lldp run
Syntax: [no] lldp run

 

If your VoIP phone uses CDP, enable CDP.

 

Brocade(config)# cdp run
Syntax: [no] cdp run

Re: Trouble with Voice Vlan and dhcp

Hi,

 

does the phone get an IP address or not ? Sometimes you need to configure a vendor specific DHCP option (i.e. 156) for phones to download config and switch to a different vlan.

 

Thank you

Re: Trouble with Voice Vlan and dhcp

Hi

 

i have the same problem. I had a Fast Iron Router/Swicth as my Core and get it off the way and use a Stack of FCX as the new core with a router flash image. All other nodes works as usually do but I cant get IPs for my Avaya phones. In adittion im having one way audio on the call between extension in campus but with call from the outside works just fine. Have any idea how to solve it ??!!!!
