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,
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.
