The following is a description of the display fields:

Service Class

Shows the type of service class.

 

 

UBR indicates Unspecified Bit Rate

 

 

CBR indicates Constant Bit Rate

 

 

RT-VBRindicates Real-time Variable Bit Rate

 

 

NRT-VBRindicates Non Real-time Variable Bit

 

 

Rate

Peak Bit Rate

Shows the maximum bit transmission rate.

Sustained Bit Rate

Shows the average bit transmission rate (in

 

 

Kilobits per second).

Maximum Burst Size

Shows how many cells can be transmitted at the

 

 

Peak Bit Rate.

Encapsulation Type

Shows the encapsulation scheme to transport

 

 

multi protocol data over the AAL5 layer.

 

 

Routed-LLCindicates logical link control

 

 

encapsulation (default).

 

 

Routed-VCMUXindicates VC-based

 

 

multiplexing encapsulation.

F5-OAM

Shows how OAM (Operation, Administration,

 

 

and Management) loopback cells provide

 

 

loopback capabilities and confirm whether a VC

 

 

connection is up. Only F5 OAM segments are

 

 

supported, which provides loopback capabilities

 

 

on a VC connection level.

 

 

Responses Only indicates that the port will

 

 

respond but doesn’t generate OAM cells.

 

 

Requests & Responses indicates that the port

 

 

will respond and generate OAM cells.
