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; 1stand-byfront panel port)

9A426-02(2 active front panel ports)

Local Management Screens

The screens shown in this appendix are for the 9A426-02ATM Module. The screens for the9A426-01ATM Module differ in that there is no Port # field, since the9A426-01ATM Module has only one active front panel port.

Modifying Fields and User Privileges

To modify fields on these modules, you must have read-writeorsuper-userprivileges. If you haveread-onlyprivileges, 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-configuredby an administration function, and are usually established forlong-termuse. 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.

Connection Table Screen Fields

The following information briefly explains each Connection Table Screen field.

ATM Port Current Connections

Number of virtual circuits that are currently open for this port.

ELAN:

Name of the ELAN to which this client is joined.

NOTE

For more detailed information about this field, see the description for the ELAN Name: field on page 13.

VPI

Displays the Virtual Path Identifier number of the listed PVC or SVC.

VCI

Displays the Virtual Channel Identifier number of the listed PVC or SVC.

Encapsulation Type

Displays the method used to encapsulate data at the ATM Adaptation Layer 5 (AAL5) for each connection. The 9A426-01and9A426-02ATM 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.

7

9A426-01/9A426-02Module 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.

To select another ELAN, use the arrow keys to highlight the ELAN: field (bottom left corner of the screen), then press theSpace Bar.

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-configurethe next time it is started. Use theSpace 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-specificLocal 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 theReturn key. HighlightSAVE and press theReturn 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.

NOTE

Future releases will support multiple ELANs. Check your release notes to determine whether your release supports multiple ELANs.

13

9A426-01/9A426-02Module 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 theSpace 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 theSpace Bar.

Adding an ELAN

NOTE

Remember, while we support just a single ELAN, you cannot create a new ELAN unless all current ELANs have been deleted.

To add an ELAN:

1.Use the arrow keys to highlight CREATE, then press theReturn key.

2.Use the arrow keys to move to the ELAN Name field.

14

9A426-01/9A426-02Module Specific Information

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 theReturn key.

The message “SAVED OK” is displayed.

Deleting an ELAN

To delete an ELAN:

1.Use the arrow keys to highlight DELETE, then press theReturn key. The message “PRESS SAVE TO CONFIRM DELETE” is displayed.

2.Use the arrow keys to highlight SAVE, then press theReturn key.

The message “SAVED OK” is displayed. The ELAN Name field will be updated after you exit the LEC Administration Screen.

Modifying an ELAN

To modify an ELAN:

1.Use the arrow keys to highlight MODIFY, then press theReturn key.

2.Use the arrow keys to move to the field you want to modify.

3.Press the Space Bar to modify (select) another option.
