• The TFTP Server must be capable of supporting multiple TFTP sessions.
• When a wireless handset makes a TFTP request it uses file names
without a full path name. Therefore, software updates for the WLAN IP
Telephony Manager 2245 and WLAN Handsets 2210/2211 must be
installed into the root directory of the TFTP Server.
When the software files are uploaded to the TFTP server. they must be
unzipped. Allow time for the TFTP server to refresh and be aware of the files
before attempting to download software to the wireless handsets and WLAN
IP Telephony Manager 2245. Monitor the TFTP Server for any errors.
The TFTP Server can be located anywhere on the network if then wireless
handsets have the subnet mask and default IP gateway configured correctly.
However, the wireless handset expects a response within two seconds to any
TFTP request. Therefore, the TFTP Server should not be located, for
example, at the other end of a slow WAN link.
If too many wireless handsets are attempting to download new software
simultaneously, it can cause the downloads to slow down or return error
messages. To reduce the number of retries and error messages, manage the
download process by staggering the times the wireless handsets download the
software.
Nortel Networks has tested the following TFTP servers. They are listed in
order of preference.
• Nortel Networks TFTP server (ONMS application)
•3COM TFTP
• PumpkinTFTP
Syslog Server planning
A Syslog Server listens for incoming syslog messages on UDP port 514 and
then processes the messages according to local administrative procedures.
Usually the syslog messages are logged for subsequent review by the system
operator. A number of devices used within a WLAN Handsets 2210/2211
wireless configuration are capable of sending messages to a Syslog Server.
