You have configured the Enable Keep Alive check box under Trace Filter Settings. How does this
change the trace output?
A.
It adds TCP socket numbers between the endpoint and Cisco Unified CallManager for the
session.
B.
It maps the unique TCP handle for the endpoint to the MAC address of the endpoint in the trace
output.
C.
It adds the IP address of the endpoint in hex.
D.
It adds the SCCP messages and all fields sent as part of that message.
Explanation:
Enable Keep Alive Trace Activates trace for keepalive trace information in theCisco CallManager
traces. Because each SCCP device reports keepalive messagesevery 30 seconds, and each
keepalive message creates 3 lines of trace data.
