Visara CNA-8000 Installation - Manual (Page 88)

Chapter 6. Ethernet Gateway
6-14 707158-003
DLSw Version: Two DLSw versions are supported by the CNA-8000. Version 1
represents remote nodes that adhere to RFC 1434. This is typically a Visara 1174
controller, but could also be an IBM 6611 router or possibly some other platform that
supports RFC 1434. Version 2 represents remote nodes that support RFC 1795. This is
the more commonly supported RFC supported by most router vendors. Note that
platforms that support RFC 2106 should use the Version 2 setting, as those platforms
should negotiate backwards to RFC 1795 compatibility.
Keepalive Timeout (secs): This parameter indicates whether you want to invoke a
keepalive timer to determine when a remote node has gone away. Setting a non-zero
value indicates the interval of the timer. A value of zero indicates that the Keepalive
timer is disabled. Identifying that a node is no longer connected allows the CNA-8000 to
request VTAM to clean up the connection (allowing VTAM to accept another connection
through a different gateway).
Button Definitions
Return: Pressing this button will return you back to the ‘Configure Ethernet Line’ panel.
Update: Selecting the Update button will save the current values. If there is a value in
error, an error message will display to the right of the buttons to inform you of the
problem.
Delete: Select the DLSw Drop that you wish to delete from the Drop ID dropdown
control and press the [Delete] button to dispose of the definition. Upon confirmation of
your request the drop will be deleted and the listing of that drop will be removed from the
list.
New: Pressing this button will cause the Drop ID field to change from a dropdown list to
a data entry field and defaults for the new drop will appear. Make the configuration
changes needed for the new drop; then press the Update button to save the information.
