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,

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.

respond but doesn’t generate OAM cells.
Requests & Responses indicates that the port
will respond and generate OAM cells.
