DHCP Configuration for SwyxPhone L420 (kb2208)
The information in this article applies to:
- SwyxWare v4.20
- Microsoft Windows 2000 Server
- SwyxPhone L420
The SwyxPhone L420 must be configured for operation in the network. This can either be done locally on each phone or centrally via DHCP or DNS server.
This article describes how to configure the DHCP server to centrally configure the SwyxPhones L420.
The SwyxPhone must have the following information for the IP configuration:
- IP address for the telephone itself
- Network mask of the subnet in which the telephone is to be operated
- IP address of the router (required if your local network has various IP subnets)
- IP address of the computer on which the SwyxPhoneManager runs
- An optional additional IP address for a second SwyxPhoneManager - this is called the BackupSwyxPhoneManager.
While starting, the SwyxPhone will attempt to connect to a SwyxPhoneManager twice: Once with the SwyxPhoneManager address and once with the BackupSwyxPhoneManager address. If there is no BackupSwyxPhoneManager in the system, you should enter the SwyxPhoneManager address here a second time.
The above mentioned information can be assigned to the telephone via DHCP. The following DHCP options are of interest here:
Please read the description for your DHCP server in order to set up DHCP options 1 and 3. The `Vendor Specific Info' option is a general option which can serve different purposes and, for this reason, it is only possible to enter a byte sequence in the configuration of the DHCP server. In order to use this option for transmitting the SwyxPhoneManager address, a byte sequence must be entered there according to the following pattern.
If the IP address of SwyxPhoneManager is 10.20.30.40, for example,
and the IP address of the BackupSwyxPhoneManager is 18.104.22.168,
then the following byte sequence must be entered:
The beginning of the byte sequence 80, 72, 79, 78, 69, 77, 71, 82 ("PHONEMGR" in ASCII) serves an identification purpose and it helps to prevent a misconfiguration if this option is used elsewhere.
Please pay attention to the 0 at the end.
Using the Microsoft DHCP server the configuration would look like:
