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

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.

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.

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.

Displaying the Add/Delete Entry Screen

To display the Add/Delete Entry Screen, use the arrow keys to highlight

ADD/DELETE ENTRY, then press the Returnkey.
