 Cisco call manager
CCM, Cisco 4503, Cisco switch, Cisco VLAN, DHCP, TFTP Server
My old setup for cisco voice network-

PRI Line router --> CCM 4.1 --> cisco 4503 core switch--> Access switches --> Ip Phone devices.

Ip Addresses are statically configured in all ip phones according to vlans. tftp server is our call manager for loading ios flash to ip phone.

Now my company is asking for enable DHCP on all phone for ip address allocation. For this i can configure dhcp pool in core switch where intervalan routing is configured. But i do not know how the ip phone talk with tftp server (call manager) for loading the ios flash while booting.

kindly suggest command

 



Software/Hardware used:
cisco core switch 4503, CCM 4.1

Answer Wiki:
If you are configuring DHCP in IOS on your 4500 then you will be creating a pool for each of the required VLANs. In the pools that have IP handsets use DHCP option 150 to return the IP address of your TFTP server to the DHCP clients as well as other information such as IP address, mask etc....... Here is an example: switch(config)#ip dhcp pool LAN switch(dhcp-config)#network 10.0.0.0 255.255.255.0 switch(dhcp-config)#default-router 10.0.0.254 switch(dhcp-config)#dns-server 1.1.1.1 2.2.2.2 switch(dhcp-config)#domain-name techtarget.com switch(dhcp-config)#option 150 ip 10.1.1.1 switch(dhcp-config)#exit Obviously replace all IP addresses with your information. ;)
