Excess Burst
The excess burst rate (B
e
) combines with the committed burst rate to determine
the maximum number of bits the router can transmit over a specified time interval
when there is no congestion. The excess burst plus the committed burst must be
less than or equal to the line speed. To change the value for the excess burst:
1.
Navigate to the prompt for the PVC that you want to edit.
For example:
box; serial/1/2; frame-relay/1/2; orlando; pvc/1/2/51
2.
Enter the
excess-burst
command and the value you want the PVC to use:
excess-burst
<integer>
<integer>
is the number of bits the router can transmit per time interval.
Legal values are 0 to 2,147,483,647 bits. The default is 0.
For example, the following command line sets an excess burst value of 2,000
bits:
pvc/1/2/51# committed-burst 2000
pvc/1/2/51#
CIR (Throughput)
The CIR (committed information rate) defines the number of bits per second your
carrier guarantees the router can transmit over a specified time interval when there
is no congestion. Your carrier supplies this value:
1.
Navigate to the prompt for the PVC that you want to edit.
For example:
box; serial/1/2; frame-relay/1/2; newyork; pvc/1/2/51
2.
Enter the
cir
command and the value you want the PVC to use:
cir
<integer>
<integer>
is the number of bits the router can transmit per time interval.
Legal values are 0 to 2,147,483,647 bits. The default is 0.
