Hi,
I have connected Cisco IP phones to Extreme X460 switches, but my Cisco Phones is not getting IPs form the Voice VLAN. As I have already configured all the data & voice vlan in my blackdiamond 8810 core switch. Any suggestion please will be highly appreciated.

If the phones support LLDP use the following to bring up a cisco phone in the voice vlan. You will need to adjust ports as needed for your switch and/or blades that you want to configure for LLDP.

configure lldp port 1-52 advertise system-name

configure lldp port 1-52 advertise vendor-specific dot3 mac-phy

configure lldp port 1-52 advertise vendor-specific med capabilities

configure lldp port 1-52 advertise vendor-specific med policy application voice vlan voice dscp 46

configure lldp port 1-52 advertise vendor-specific med power-via-mdi

enable lldp ports 1-52
