Admin Tip
Spectralink 80-Series Handsets cannot roam with uninterrupted service between
subnets unless specific LAN components are present. Certain AP/Ethernet switch
combinations establish a layer-2 tunnel across subnets that enable the handsets to
roam. Without this capability, any call in progress will be dropped when the user
moves out of range and the handset must be power cycled in order to resume
functionality in the new subnet area.
Ensure that all your APs are attached to the same subnet for proper operation. The
handset can change subnets if DHCP is enabled and the handset is powered off then
back on when within range of APs on the new subnet.

configuration information.
TFTP Server IP
The IP address of a TFTP server on your network which holds software
images for updating the wireless telephones. If this feature is configured (not set to 0.0.0.0 or
255.255.255.255) either via Static IP configuration or using DHCP option 66 (TFTP server), or
the Boot server/next server (siaddr) field, the wireless telephone will check for newer software
each time it is powered on or comes back into range of your network. This check takes only a
second and ensures that all wireless telephones in your network are kept up-to-date with the
same version of software.
Syslog Server IP
The IP address of the syslog server. See Chapter 6
Diagnostic Tools
for
more information.
Time Server IP
The IP address of the time server. The time server controls the date/time
information that is displayed in standby mode.
SSID
Enter the SSID.
