The following is an example of the information that is displayed with the command listed
above:
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-VBR indicates Real-time Variable Bit Rate
NRT-VBR indicates 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-LLC
indicates logical link control
encapsulation (default).
Routed-VCMUX
indicates VC-based
multiplexing encapsulation.
• F5-OAM Shows how OAM (Operation, Administration,
