The CIR is calculated from the B
the Frame Relay carrier guarantees to forward during a certain interval of time
(T). The CIR is equal to B
You should set a B for each Frame Relay subinterface to ensure that the PVC
c
does not exceed its CIR. Some Frame Relay service providers may charge your
company extra if your company consistently transmits over its CIR.
The industry standard is to calculate the time interval as 1 second. As a result,
the B is essentially the CIR. To set the CIR, enter the following command
c
from the Frame Relay subinterface configuration mode context:
Syntax: frame-relay bc <committed burst value>
Replace <committed burst value> with your CIR expressed in bits. You can
set a B between 0 and 4,294,967,294 bps.
c
For example, you might enter:
ProCurve(config-fr 1.1)# frame-relay bc 256000

Set the EIR

When your company negotiated a SLA, the terms of that agreement probably
allowed for a burst rate on the Frame Relay connection. This burst rate is
called the Excess Information Rate (EIR), which defines the maximum
amount of traffic your company is allowed to send over its CIR.
The B sets the maximum number of bits that the router can transmit during
e
T. Just as B is equal to the CIR, B
c
at which the ProCurve Secure Router can burst data above the CIR when there
is no congestion on the Frame Relay network.
If you enter a value for the frame-relay bc command, you should also
configure a burst rate for the Frame Relay link. Otherwise, the link will be
limited to the bandwidth you specified in the frame-relay bc command.
Together, the frame-relay bc and the frame-relay be commands define the
amount of bandwidth you can use on the Frame Relay link. The sum of the
values you specify for these two commands should be greater than 8000.
To configure the EIR for the Frame-Relay link, enter:
Syntax: frame-relay be <excessive burst value>
, which is the maximum number of bits that
