Appendix
9A426-01/9A426-02
Module Specific Information
Introduction
This appendix contains local management information that is specific to the
following ATM Modules:
• 9A426-01 (1 active front panel port; 1 stand-by front panel port)
• 9A426-02 (2 active front panel ports)
Local Management Screens
The screens shown in this appendix are for the 9A426-02 ATM Module. The
screens for the 9A426-01 ATM Module differ in that there is no Port # field, since
the 9A426-01 ATM Module has only one active front panel port.

Modifying Fields and User Privileges
To modify fields on these modules, you must have read-write or super-user
privileges. If you have read-only privileges, you can view information; however,
you cannot modify any fields.
Virtual Channels and Virtual Paths
Rather than addressing cells to a specific destination, as in a LAN, ATM addresses
cells to Virtual Channels (VCs) and/or Virtual Paths (VPs). This addressing takes
place in the header field of the ATM cell.
VCs and VPs are bi-directional (i.e., they transfer information in both directions
on a single channel or path) and are “set up” between devices on the ATM
network prior to transmission. Similar to WAN transmission, ATM technology
provides the ability of sending several VCs together over a VP, and several VPs
over an ATM link segment.
Permanent and Switched Virtual Channels
ATM networks use two different types of Virtual Channels:
• Permanent Virtual Channels (PVCs)
• Switched Virtual Channels (SVCs).
The difference between PVCs and SVCs exists in the channel setup.
PVCs are pre-configured by an administration function, and are usually
established for long-term use. After setting up this channel, nothing else is
required by the network to transfer information between the two established
points. This type of virtual channelling is established through a local or remote
management interface.
SVCs use a signaling and network switching procedure to set up dynamically. In
other words, SVCs are established “on the fly,” as needed for a particular service,
used to transmit on the short term, and then terminated.

FNB Resource Configuration Screen
The 9A426-01/9A426-02 FNB Resource Configuration Screen (Figure 1), lists all
possible connections a module can support on the FNB, displays the current
connection, and allows you to change the connection.

FNB Resource Configuration Screen Fields
The following information briefly explains each FNB Resource Configuration
Screen field.
Current FDDI Con:
Displays the current connections of the selected module to the
SmartSwitch 9000 FNB.
Config ID
Displays an identification number that is automatically assigned to each
configuration.
FDDI Connections
Displays all possible connections of the selected module to the
SmartSwitch 9000 FNB.
Changing the Current FNB Connection
To change the current FNB connection:
1. Use the arrow keys to highlight the desired FDDI connection.
2. Press the Return key.
3. The connection you selected appears in the Current FDDI Con: field.
4. Use the arrow keys to highlight SAVE, then press the Return key.
The message “SAVED OK” appears. This message indicates that the FNB
connection you selected has been implemented. If you exit without saving, the
message “NOT SAVED -- PRESS SAVE TO KEEP CHANGES” appears, and
the FNB connection you selected will not be implemented.
5. Use the arrow keys to highlight RETURN , then press the Return key.
