I set up a DHCP on a router.
iip dhcp pool VOICE
network 172.17.30.0 255.255.255.0
option 150 ip 172.17.30.10 172.17.30.11
No i need to set the lease for about 30 minutes.
lease 0 0 30 ?
second how can i clear out the leases or have then refresh so the phones know that the lease is for only 30 minutes.
