ATM Configuration
3-4 Configuring Connections
Selecting the Add button either adds a new connection or modifies an existing
one, using the parameters entered in the fields below the list box. A confirmation
window will appear for both additions and modifications.
Selecting the Delete button deletes the selected connection; a confirmation
window requires that you confirm the deletion.
Selecting Refresh refreshes the connection information displayed in the window.
Configuring Connections
Adding a New Connection
To configure new Permanent Virtual Circuits (PVCs), enter the following
information in the text fields which appear just below the settings list box:
1. In the I/F text box, click on the down-arrow to the right of the text field, and
drag down to select the interface for which you wish to configure a connection.
All available ATM interfaces will be listed in this menu: index 4 for the
9A128-01.
2. In the VPI text box, enter the Virtual Path Identifier you wish to assign to this
connection. Allowable values are 0 to 3; remember, the VPI you assign will be
used to group virtual connections, allowing for channel trunking between ATM
switches.
3. In the VCI text box, enter the Virtual Channel Identifier you wish to assign to
this connection. Allowable values are 0 to 1023 for each VPI. For example,
you could assign the same channel identifier — say, 25 — as many as four
times: once with a VPI of 0, once with a VPI of 1, and so on. Again, remember
that it is the combination of VPI and VCI that will be used to direct cells
through the intermediate switches between the source and destination.
NOTE
Current versions of 9A128-01 firmware do not support the ability to add new
connections, delete existing connections, or modify existing connections.
