The following list shows the menu options and an explanation of each:
[M] Module status—This feature has three options. To see the status of the module, use the S option;
the other two choices let you either enable or disable the module.
•
[I] Port priority (spanning tree)—This option sets the port priority for the STP root port. The lower
the number, the higher the priority. The valid range is from 0 to 255; the default is 128.
•
[C] Path cost (spanning tree)—This option sets the path cost used to choose the STP root port.• [H] Port fast mode—PortFast is an option that allows a port to immediately go into forwarding mode.
This option offers two settings: E (enable) and D (disable). (The option is explained in detail in
Chapter 10.)
•
[L] Novell SNAP frame translation—This option determines whether manual or automatic
frame−translation is used by IPX.
•
[U] Unmatched SNAP frame destination—This option identifies the translation of frames for which
the frame type cannot be determined. To use this option, option L should be set to automatic.
•
[R] Reset module—This option resets the expansion modules.• [F] Reset to factory defaults—This option resets the expansion modules’ configuration to the factory
defaults.
•
[1] Basic FDDI settings—This option allows you to see the first expansion module’s status and
current configuration.
•
[2] Secondary FDDI settings—This option displays the second screen of the expansion module’s
status and current configuration.
•
[A] Port addressing—This option is used to access the Port Addressing menu.• [V] View port settings—This option is used to display an individual port’s statistics.• [N] Next port—This option is used to forward to the next configurable port.• [G] Goto port—This option is used to configure any identified port.• [P] Previous port—This option is used to configure the previous configurable port.• [X] Exit to Main Menu—This option returns you to the Main Menu.•
