ATM Connection Setup Screen

The following list explains each of the ATM Connection Setup screen fields:

Total Bandwidth Available (Read-Only)

Shows the resources the current APIM has available for the assignment of PVCs and their associated traffic descriptors. If there are no PVCs configured, the maximum bandwidth the active APIM supports is displayed. For example, an APIM-21 will display 155 Mbps. As PVCs with traffic descriptors are assigned, their rate is subtracted from the total.

ATM Port Current Connections (Read-Only)

Displays the number of current connections on the VHSIM2-A6DP.

IF (Read-Only)

Represents the virtual MIB-II interface on which this Virtual Channel (VC) was created. This field can represent both Switched Virtual Channels (SVCs), and Permanent Virtual Channels (PVCs). These virtual MIB-II interfaces will also display on the Switch Configuration screen of the host device. If the status of a PVC is down, an asterisk (*) appears to the left of the IF field next to the PVC that is down, and the message “* Operational Status for the indicated connection(s) is ‘down’.” will appear at the bottom of the screen.

PORT (Read-Only)

Displays the application port on which the PVC or SVC resides. Once a PVC is created, it is dynamically assigned a switch port number. This port number then may be assigned to an 802.1Q or SecureFast VLAN, depending on the operational mode of the host device. If this connection is an SVC, the switch port number is assigned to the LEC to which this SVC belongs. The UNI and ILMI connections will display “0”.

VPI (Read-Only)

Displays the Virtual Path Identifier of the connection. This field reads 0 or 1 (currently, only 0 and 1 are supported).

VCI (Read-Only)

Displays the Virtual Channel Identifier of the connection. This field reads between 32 and 4095.

Encapsulation Type (Read-Only)

Displays the type of Encapsulation being used to switch Ethernet frames to ATM cells. The three possible options for this field are as follows:

LANE - VC Based Multiplexed 802.3 LAN Emulation. This method is specified by the ATM Forum LAN Emulation specification. This option is available for SVCs only.

VC Mux 802.3 Bdg - VC Based Multiplexing for Bridged Protocols as defined by the IETF RFC 1483. This encapsulation type is for PVCs only.
