3.3.1 BRIM-A6 Setup Screen Fields

The BRIM-A6 Setup screen displays settings for each PVC and SVC that is configured to the BRIM. The following list explains each of the BRIM-A6 Setup screen fields:

ATM Port Total Current Connections: X

This field displays how many connections (PVCs and SVCs) are configured to the BRIM-A6.

VPI

This field displays the Virtual Path Identifier (VPI) of each connection. You assign VPIs in the BRIM-A6 Add/Delete Entry screen.

VCI

This field displays the Virtual Channel Identifier (VCI) of each connection. You assign VCIs in the BRIM-A6 Add/Delete Entry screen.

Encapsulation Type

This field displays the method used to encapsulate data at the ATM Adaptation Layer 5 (AA-L5) for each connection. The BRIM-A6 supports the following methods of encapsulation:

•VC Mux 802.3 LANE: VC Based Multiplexed 802.3 LAN Emulation This method is specified by the ATM Forum LAN Emulation specification. This is the default encapsulation method.

•VC Mux Bridged 802.3: VC Based Multiplexing for bridged protocols as defined by the IETF RFC 1483.

•LLC Encapsulation: Logical Link Control for Bridged Protocols as defined by the IETF RFC 1483.

AAL Type

This field displays the ATM Adaptation Layer (AAL) type of each connection. The AAL divides the user information into segments suitable for packaging into series of ATM cells. The ATM Forum’s LAN Emulation specification dictates that AAL-5 be used for all LAN emulation traffic. The BRIM-A6 supports AAL-5 and AAL-3/4.

Oper. Status

This field displays the operational status of each connection. Possible conditions are Enabled or Disabled.
