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 are logged to the
system log server. Also enable Network Time Protocol (NTP) so that all access points and switches use the
same times.
For information about setting up a system log server, see Set Up Trace Settings, on page 96.
Phone Trace Logs
When you are experiencing problems registering with Cisco Unified Communications Manager, or call
connections, you can use the Trace Logs function to trace the path of a packet from the phone to
Cisco Unified Communications Manager. The result shows the number of hops and the IP address of each
hop to reach the Cisco Unified Communications Manager server. You can use this information to check
connectivity between the phone, Cisco Unified Communications Manager servers and gateways during a call.
To download trace logs, click Download Logs from the Trace Logs page.
