Module Specific Information
Introduction
This appendix contains local management information that is specific to the
following ATM Modules:
9A128-01 (1 Port, Multimode Fiber, SC Connector)
9A129-01 (1 Port, Single-Mode Fiber, SC Connector)
Module Interfaces
The 9A128-01 and 9A129-01 ATM Modules have four interfaces. Table 1 lists the
identifying number, name, and description of each interface.
Use the numbers listed in Table 1 to configure the module’s default interface (see
the General Configuration Screen).

FNB Resource Configuration Codes
The 9A128-01 and 9A129-01 ATM Modules provide connectivity between two
interfaces: the front panel interface and one of the FDDI rings on the backplane
(FNB-1 or FNB-2).
The FNB Resource Configuration Screen allows you to connect the module’s front
panel interface to one of the chassis’ two FDDI networks (FNB-1 or FNB-2) via a
bridge/router.
The FNB Resource Configuration Screen lists all the possible connections that the
module can support on the FNB, displays the current connection, and allows you
to change the connection. Table 2 lists and describes the FDDI connections from
which you can select.

9A128-01 and 9A129-01 Module Specific Information
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 to send 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) and 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.

following methods of encapsulation:
VC Mux 802.3 LANE (default)
VC Based Multiplexed 802.3 LAN Emulation. This method is specified by the
ATM Forum LAN Emulation specification.

LEC Administration Screen Fields
The following information briefly explains each LEC Administration Screen field.
LEC Index
Displays the MIB II interface number. Valid values are 4 through 67.
Configure ELAN (Toggle)
Specifies whether the LAN Emulation Client should auto-configure. Use the
Space Bar to select one of the following choices:
Automatic (default) - A client uses a LAN Emulation Configuration Server
(LECS) to learn the ATM address of its LAN Emulation Server and to obtain
other parameters.
Manually - The ATM address of the LAN Emulation Server (LES) and the
values of other parameters must be entered by the user.
ELAN Name
The name of the ELAN to which this client is joined.
By default, the unit makes a LANE join request to the ATM network with the
ELAN name blank (no entry). By popular LANE convention, Join Requests of this
type will put that client into the first configured ELAN on the LECS (also known
as the “default ELAN”). Assume this ELAN is named “ELAN1”. Once the device
has successfully completed the Join process, all ATM-specific Local Management
screens will then reflect “ELAN: ELAN1”. This means that all Local Management
screen information pertains to the “ELAN1” ELAN.
To set the device back to join the “default” ELAN, you must delete the current
ELAN (ELAN1). After the current ELAN is deleted, a message is displayed that
states that there are no longer any active ELANs. Now, you can move to the
ELAN Name field. Press the Space Bar and then the Return key. Highlight SAVE
and press the Return key. This will cause the device to join the “default ELAN”
again.
Since we support just a single ELAN, you cannot create a new ELAN unless all
current ELANs have been deleted.
If there are currently no active ELANs, then all choices on the ATM Specific
Configuration Screen will result in the message “No ACTIVE ELAN present”. You
can only access the Connection Table screen and the LEC Administration screen.
You cannot access the LEC Properties screen, since there is no information.
Future releases will support multiple ELANs. Check your release notes to
determine whether your release supports multiple ELANs.
NOTE

the Initial State. Use the Space Bar to select one of the following choices:
1516 (default)
4544
LAN Type (Toggle)
The data frame format this LEC is using currently. Use the Space Bar to select one
of the following choices:
802.3 (default)
802.5
LES ATM Address
The LES this client will use the next time it is started in manual configuration
mode.
Adding an ELAN
To add an ELAN:
1. Use the arrow keys to highlight the Configure ELAN field.
2. Press the Space Bar to select either Automatic or Manually.
3. Use the arrow keys to move to the ELAN Name field.
4. Type the name of the ELAN you want to add.
5. Use the arrow keys to move to the Max MTU Size and LAN Type fields. Using
the Space Bar, select the appropriate choice for each field.
6. Use the arrow keys to highlight ADD/MODIFY, then press the Return key.
The message “ADD COMPLETE” is displayed.
Remember, since we support just a single ELAN, you cannot create a new ELAN
unless all current ELANs have been deleted.
