Kernel Debug Messages Enabled Checkbox: This determines whether Kernel Debug
Messages get included in the debug trace. Additional information to make use of this
option can be found in the CNA-8000 Problem Determination manual.
Log Which Events:
The check boxes allow you to select which types of messages are included in the main
event log. Unless you have a reason for excluding events, it is probably best to allow all
messages to get recorded. Below is a list of message categories that can be included or
excluded.
 Server Events
 ESCON Events
 SSP Events
 Error Events
 LLC Events
 Administrative Events
 Token Ring Events
 Ethernet Events
 Hardware Events
 XCA Events
 eManager Events
TN3270 Keepalive Policy:
Keepalive messages are used to determine whether a TN3270 client is still
communicating with the server when there is little traffic conducted between the client
and the CNA-8000. When enabled, a Telnet ‘Do Timing Mark’ is sent to the client
periodically, requiring the client to respond back with an acknowledgement which is
interpreted that the client is still communicating. If no response is received within a
specific timeframe the CNA-8000 will close the client session, making it available for
another potential user. There are two options configurable for sending Keepalive
messages to TN3270 clients.
 Enable/Disable Keepalive – determines whether Keepalive will be used.
 TN3270 Keepalive Interval – Determines in seconds how long the CNA-8000
will wait before sending a Keepalive message to the client.
