Profile Name

This name identifies the profile.

 

 

Encap.

This field displays the type of encapsulation (LLC or VC).

 

 

AAL

This field displays the ATM Adaptation Layer (AAL).

 

 

Class

This field displays the type of ATM traffic class: cbr (constant bit rate), rt-vbr(real-time variable bit

 

rate), nrt-vbr(non real-time variable bit rate), ubr (unspecified bit rate) or abr (available bit rate).

 

 

PCR

This is the Peak Cell Rate (PCR), the maximum rate at which the sender can send cells.

 

 

CDVT

This field displays the accepted tolerance of the difference between a cell’s transfer delay and the

 

expected transfer delay.

 

 

SCR/MCR

The Sustained Cell Rate (SCR) sets the average cell rate (long-term) that can be transmitted. SCR

 

applies with the rt-vbrand nrt-vbrtraffic classes.

 

Minimum Cell Rate (MCR) is the minimum rate at which the sender can send cells. MCR applies

 

with the abr traffic class.

 

 

BT/NRM

Burst Tolerance (BT) is the maximum number of cells that the port is guaranteed to handle without

 

any discards. BT applies with the rt-vbrand nrt-vbrtraffic classes.

 

The Number of Resource Management (NRM) cells is the maximum number of cells a source may

 

send for each forward Resource Management cell. NRM applies with the abr traffic class.
