ATM Configuration
Settings
The Settings portion of the window contains a list box which displays information about each of the currently configured PVCs, as well as the fields used to configure new connections:
I/F | The device interface on which the PVC was configured. |
VPI | Displays the Virtual Path Identifier assigned to the |
| connection; current versions of |
| values from 0 - 3. Virtual Path Identifiers are used to |
| group virtual connections, allowing for channel trunking |
| between ATM switches. Each VPI can be configured to |
| carry many different channels (designated by VCIs) |
| between two points. |
VCI | Displays the Virtual Channel Identifier assigned to the |
| connection; allowable values are 0 - 1023 for each VPI. |
| Each assigned VCI must be unique within its defined |
| VPI: for example, you can assign a VCI of 14 as many as |
| four times: once with a VPI of 0, once with a VPI of 1, and |
| so on. Remember, it is the combined VPI and VCI |
| designations assigned to a channel that creates the |
| grouping of virtual connections. |
Encapsulation Type | Displays the method used to encapsulate LAN packets |
| on the selected circuit. Current versions of |
| firmware use 802.3 |
| protocols (designated VC MUX 802.3 Bridged); future |
| versions will add support for ATM Forum LAN |
| Emulation and Cabletron’s SecureFast Switching. You |
| may also see some connections assigned a type of |
| “other”; these are default connections that cannot be |
| modified or deleted. |
Status | Displays the current administrative status of the |
| connection: enabled or disabled. In current versions of |
| firmware, all connections are enabled by default, and |
| cannot be disabled. |
UpTime | The length of time the selected connection has been |
| enabled. |
NOTE |
You can only view current connections; you will not be allowed to add new connections, delete existing connections, or modify existing connections, on
Accessing the ATM Connections Window |
