How do you prevent in DHCP environments the Com-Server from getting an unintended IP address?
The Com-Server uses the DHCP-compatible BOOTP protocol to avoid this problem. In contrast to DHCP, this is based on fixed (stored in a corresponding database) reservations of certain
IP addresses for certain MAC addresses. This means a DHCP server in the network will not assign an IP address without a corresponding entry for the MAC address. Since some DHCP implementations (e.g. Win2000 servers) however use their standard setting to treat BOOTP and DHCP requests the same, we recommend deactivating the BOOTP client of the Com-Server if you want to send the IP address serially or via ARP. There are two ways to turn it off:
– per Telnet configuration for Com-Servers already in operation
– serially by appending the characters “-0” behind the IP address.
Note: DHCP/BOOTP protocol is only available in Com-Servers having NO coax terminal.
