If a DHCP server for the assignment of IP addresses is active in the LAN, an unconfigured LANCOM device disables its own DHCP server, switches to DHCP client mode and retrieves an IP address from the DHCP server in the LAN. However, this IP address is initially unknown and accessing the device depends on the name resolution:
- If the LAN also has a DNS server for name resolution and this communicates the IP address/name assignment to the DHCP server, the device can be reached under name "-<MAC address>", e.g. “-00a057xxxxxx”.
Note: The MAC address on a sticker on
the base of the device.
- If there is no DNS server in the LAN, or if it is not coupled to the
DHCP server, the device cannot be reached via the name. In this case
the following options remain:
- Use LANconfig's “Find Device” function, or perform WEBconfig's “Device Search” from another yet accessible LANCOM.
- Use suitable tools to find out the IP address assigned to the LANCOM by DHCP and access the device directly using this IP address.
- Use the serial configuration interface to connect a computer running a terminal program to the device.
