undo ebs [ inbound | outbound ]

Frame relay class view

inbound: Sets the EBS in inbound direction, valid only when FRTP is enabled on 
the interface.

outbound: Sets EBS in outbound direction, valid only when FRTS is enabled on 
the interface.

excess-burst-size: EBS in bit, ranging from 0 to 16000000. It defaults to 0 bit.

Use the ebs command to set EBS of FR virtual circuit.

Use the undo ebs command to restore the default value.

EBS is the maximum of the part that packet traffic exceeds the committed burst 
size (CBS) within an interval of Tc. When congestion occurs on the network, this 
part of excess traffic will be first discarded.

When this command is used, the set EBS value will be valid in both inbound and 
outbound directions if the parameters inbound and outbound are not specified.

# Set the EBS of the FR class named test1 to 32000 bits.

Frame relay class view

queue-length: FIFO queue length, namely, the maximum number of packets that 
can be held by the queue, ranging from 1 to 1024. By default, it is 40.

Use the fifo queue-length command to set the FIFO queue length of FR virtual 
circuit.

Use the undo fifo queue-length command to restore the default value.
