Ring Speed: This dropdown control allows you to specify which ring speed is to be
used. Most of the time you will want to leave the option set to Auto Negotiate the correct
interface speed. If you have difficulty making contact with the Token Ring card remotely,
you may want to assign a speed to the interface to match the switch/hub that you will be
attaching to. Valid options for this parameter are:
 Auto Negotiate
 4 Mbit
 16 Mbit
 100 Mbit
Source Routing: There are three possible configurations for this option.
 All Routes Broadcast – Source Route Bridging is used. Broadcasts to establish a
session will attempt to get to the destination over all possible routes.
 Single Route Broadcast – Source Route Bridging is used. An administrator must
configure which bridges are to be used to pass broadcasts and which ones are not,
thus reducing the number of paths that a broadcast frame has to traverse. (This is
configured on the bridges themselves, not in the CNA-8000.)
 Disable – Source Route Bridging will not be used and the destination must be on
the same logical ring as the CNA-8000.
Response Timer T1 (secs): This option identifies how long the CNA-8000 Token Ring
interface is to wait for an LLC response before declaring a timeout and retransmitting the
request.
Retry Count N2: This option identifies the maximum number of retransmissions that
will be attempted before attempting error recovery.
Inactivity Timer TI: This option identifies how long the CNA-8000 Token Ring
interface will wait between attempts to contact the session partner when there is no
session established.
Button Definitions:
Update: The Update button causes the information on the panel to update the
configuration file. You must press the [Update] button before leaving the panel if you
want the changes to be made, otherwise the changes will be discarded.
Return: Selecting this button will take you back to the Update Connectivity
Configuration panel.
Drops: Selecting this button displays the LLC Drops panel.
Unconfigure: Selecting this button allows you to delete the Token Ring configuration
that is currently displayed.
