Configuring ATM Connections
Settings
The Settings group box contains information about each of the currently conÞgured PVCs, as well as the Þelds used to conÞgure new connections.
I/F | The device interface index on which the PVC was conÞgured. An |
| ATM SSIM installed in the left hand slot will have an I/F value of |
| 21; an ATM SSIM installed in the right hand slot will have an I/F |
| value of 25. |
VPI | The Virtual Path IdentiÞer assigned to the connection. Allowable |
| values are 0 - 3. VPIs are used to group virtual connections, |
| allowing for channel trunking between ATM switches. Each VPI |
| can be conÞgured to carry many different channels (designated |
| by Virtual Channel IdentiÞers) between two points. |
VCI | The Virtual Channel IdentiÞer assigned to the connection. |
| Allowable values are 0 - 1023 for each VPI. Each assigned VCI |
| must be unique within its deÞned VPI. However, you can assign |
| the same VCI to multiple VPIs (e.g., VPI 0/VCI 14, VPI 1/VCI 14, |
| VPI 2/VCI 14, etc.). Remember, it is the combined VPI and VCI |
| designations assigned to a channel that create the grouping of |
| virtual connections. |
Encapsulation | The method used to encapsulate LAN packets on the selected |
Type | circuit. Current versions of ATM SSIM Þrmware use VC MUX |
| 802.5 LANE as the encapsulation method. |
Status | The current administrative status of the connection: Enabled or |
| Disabled. |
UpTime | The length of time the selected connection has been enabled. |
Configuring Permanent Virtual Circuits
You can use the Add, Delete, or Refresh command buttons at the bottom of the Current ATM Connections window to add or delete a Permanent Virtual Circuit (PVC), or refresh the window.
¥Add Ñ adds a new connection or modiÞes an existing connection, using the parameters entered in the Þelds below the Settings list box. A conÞrmation window will appear for additions and modiÞcations.
¥Delete Ñ deletes the selected connection; a conÞrmation window requires that you conÞrm the deletion.
¥Refresh Ñ refreshes the connection information displayed in the window.
