Chapter 3 Configuring the Cisco ATA 186
About Using the DHCP Server
• Network time protocol (NTP) servers—DHCP option 42
(The Cisco ATA 186 takes up to two NTP servers)
• TFTP server name—DHCP option 66
DNS, TFTP, and NTP servers can be overwritten by the value of the
corresponding parameters in the local box profile (for example, the DNS1IP,
DNS2IP, TftpURL, and NTPIP parameters).
If you are not using DHCP, you must manually enter the IP address, network route
address, and subnet mask.
