We have 2921 router supporting DHCP pool.
I have created
ip dhcp pool voice
need to know what does command option 150 ip x.x.x.x will do under ip dhcp pool voice?
we are using cisco phones?
Solved! Go to Solution.
I am going to change my MCS server for a UCS server on vmware in a new network . Currently I have the TFTP and DHP pool service in all local routers (UCM is not giving that services). However my client wants the phones don´t move to the new network. So my new UCS server will be in a different network. Can I specify the new call manager in a different network than telephone network? Can I specify a second call manager as TFTP on a local router?
ip dhcp excluded-address x.x.x.1 x.x.x.5
ip dhcp pool local phones
network x.x.x..0 255.255.255.0
option 150 ip y.y.y.y
Thanks in advance !
You may check the ip helper-address command as described in the following link
I don´t have ip helper-address in my remote gateways. However I just moved the ip option 150 to my new UCS server and it worked properly. Now the DHCP service is in the x network and the TFTP is in the another network (y network). The phones of the old MCS server were registered properly in the new server.
Thank you for all !
