Using a System Log Server
To gather information about problems with the wired network that can cause
roaming delays or no connectivity, set up a system log server. Enable “syslog” on
the network switches and access points that is logged to the system log server.
Also enable Network Time Protocol (NTP) so that all access points and switches
use the same times.
Using the Trace Route Option on the Cisco Wireless IP Phone
When you are experiencing problems with registering with Cisco CallManager, or
call connections, you can use this function to trace the path of a packet from the
phone to Cisco CallManager. The result shows the number of hops and the IP
address of each hop to reach the Cisco CallManager server. You can use this
information to check connectivity between the phone, Cisco CallManager servers
and gateways during a call.
For information about using the Trace Route option, see the
“Performing a Trace
Route” section on page 9-24
