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.

Encapsulation Type  
Displays the method used to encapsulate data at the ATM Adaptation Layer 5  
(AAL5) for each connection. The 9A426-01 and 9A426-02 ATM Modules support  
the following methods of encapsulation:  
VC Mux 802.3 LANE (default)  
VC Based Multiplexed 802.3 LAN Emulation. This is the encapsulation type  
used when the connection is set up via SVCs. These happen automatically in  
the network with no user intervention.  
VC Mux Bridged 802.3  
VC Based Multiplexing for bridged protocols. You can choose this  
encapsulation type for PVCs to do bridging.

9A426-01/9A426-02 Module Specific Information  
LLC Encapsulation  
Logical Link Control for Bridged Protocols. You can choose this encapsulation  
type for PVCs. You cannot use this encapsulation type for SVCs.  
LLC Encapsulation inserts an LLC SNAP header for each legacy LAN  
network type that is being encapsulated onto ATM. LLC Encapsulation is  
desirable when it is not feasible for a larger number of VCs to be supported,  
due to ATM device capacity limitations or other outside factors.  
Other  
This encapsulation type is for reserved connections that are defaults built into  
most (if not all) ATM LANE 1.0 compliant devices. In other words, they are  
neither configured by hand nor set up dynamically.  
AAL Type  
Displays the type of ATM adaptation layer (AAL) used on this VCC. The AAL  
divides the user information into segments suitable for packaging into series of  
ATM cells. The AAL types are:  
AAL3/4  
AAL5 (default)  
ELAN: (Modifiable)  
Selects the ELAN for which connections are to be displayed.

LEC Administration Screen Fields  
The following information briefly explains each LEC Administration Screen field.  
Configure LEC (Toggle)  
Specifies whether the LAN Emulation Client should auto-configure the next time  
it is started. 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 - Management tells the client the ATM address of its LAN Emulation  
Server (LES) and the values of other parameters.  
NOTE  
If you set Configure LEC to Automatic, do not write to any other attribute on the  
LEC Administration screen.  
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, 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.  
Future releases will support multiple ELANs. Check your release notes to  
determine whether your release supports multiple ELANs.  
NOTE  
13  
 
 
9A426-01/9A426-02 Module Specific Information  
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.  
Max MTU Size (Toggle)  
The maximum data frame size that this client will use the next time it returns to  
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.  
ELAN: (Modifiable)  
Selects the ELAN for which attributes are to be displayed.  
To select another ELAN, use the arrow keys to highlight the ELAN: field (bottom  
left corner of the screen), then press the Space Bar.  
PORT #: (Toggle)  
Selects a specific ATM port.  
To select another port (if applicable), use the arrow keys to highlight the PORT #:  
field (bottom left corner of the screen), then press the Space Bar.  
Adding an ELAN  
Remember, while we support just a single ELAN, you cannot create a new ELAN  
unless all current ELANs have been deleted.  
NOTE  
To add an ELAN:  
1. Use the arrow keys to highlight CREATE, then press the Return key.  
2. Use the arrow keys to move to the ELAN Name field.  
14  
 
9A426-01/9A426-02 Module Specific Information  
3. Type the name of the ELAN you want to add.  
4. Use the arrow keys to move to the Configure LEC, Max MTU Size, and LAN  
Type fields. Select the appropriate choice for each field.  
5. Use the arrow keys to highlight SAVE, then press the Return key.  
The message “SAVED OK” is displayed.  
Deleting an ELAN  
To delete an ELAN:  
1. Use the arrow keys to highlight DELETE, then press the Return key.  
The message “PRESS SAVE TO CONFIRM DELETE” is displayed.  
2. Use the arrow keys to highlight SAVE, then press the Return key.  
The message “SAVED OK” is displayed. The ELAN Name field will be updated  
after you exit the LEC Administration Screen.

To modify an ELAN:  
1. Use the arrow keys to highlight MODIFY, then press the Return key.  
2. Use the arrow keys to move to the field you want to modify.
