So, with this all said.
I just need to assign one vlan (vlan 2) for all the phones, setup LLDP/CDP to boot to vlan 2 and setup DHCP helper in the switch for each floor to the proper subnet (shown below), right?
2nd floor, Vlan 2: 10.10.2.x/16
3rd foor, vlan 2: 10.10.3.x/16
4th floor, vlan 2: 10.10.4.x/16
5th floor, vlan 2: 10.10.5.x/16
Also, I will need to program 4 scope option 125 for each subnet with vlan 2?
vlan2 option 125 - "id:ipphone.mitel.com;sw_tftp=10.10.1.2;call_srv=10.10.1.2;vlan=2;l2p=5;dscp=46" 2nd floor
- "id:ipphone.mitel.com;sw_tftp=10.10.1.2;call_srv=10.10.1.2;vlan=2;l2p=5;dscp=46" 3rd floor
- "id:ipphone.mitel.com;sw_tftp=10.10.1.2;call_srv=10.10.1.2;vlan=2;l2p=5;dscp=46" 4th floor
- "id:ipphone.mitel.com;sw_tftp=10.10.1.2;call_srv=10.10.1.2;vlan=2;l2p=5;dscp=46" 5th floor
