Dynamic Address Assignment for Specific Devices
In addition to the static address assignment, you can also use dynamic address
assignment if you limit dynamic assignment to specific devices. You can use this e.g.
to easily configure VoIP devices because you do not need to assign a fixed IP address
during setup.
1. Call up the Network: DHCP page. Click Change.
2. In the Status selection, change to the Dynamic address assignment or to the
Dynamic and static address assignment setting.
3. In the Devices selection, change to the with configured MAC only setting.
For SIP system telephones (Aastra 673xi and Aastra 675xi), it is also possible to
omit the configuration of the MAC address (see Aastra 673xi/675xi DHCP starting
on page 129). In the Devices selection, change to the with configured MAC only
and SIP system devices setting. Please note, that you also need to exclude from
the configuration of an external DHCP server all MAC addresses starting with
00:08:5D.
4. Confirm with Apply.
By activating the limitation to specific devices, only known devices can get a DHCP
answer. For this, the IP address is taken from the address range used for dynamic
address allocation. If you setup a new VoIP device, it is sufficient to enter only the MAC
address.
