Monitoring Frame Relay Interfaces

Frames/Bytes transmitted

Indicates how many frames and bytes this VC has transmitted.

Frames/Bytes received

Indicates how many frames and bytes this VC has received.

Total FECNS

Indicates the number of times that this VC has been noti®ed of

inbound or downstream congestion.

Total BECNS

Indicates the number of times that this VC has been noti®ed of

outbound or upstream congestion.

Times congested

Indicates the number of times that this VC has become congested.

Times inactive

Indicates the number of times that this VC was inoperable.

CIR in bits/sec

Indicates the information rate of the VC between the range 300 bps

to 2048000 bps. A value of 0 is also supported.

Potential Info Rate

Indicates the current maximum rate in bits per second at which data

will be transmitted for the circuit. The actual data rate will depend

on the queue depths and priorities associated with the circuit.

If this ®eld has a value of ªLine Speedº, then the maximum data

rate is the actual line speed even if the line speed was not

con®gured or was con®gured incorrectly for this interface.

Committed Burst (BC)

Maximum amount of data, in bits, that the router can transmit

during the time interval (Tc). (Tc=Bc/CIR.)

Excess Burst (Be)

Maximum amount of uncommitted data in bits the router can

transmit on a VC in excess of the Bc during the time interval (Tc).

Minimum Info Rate

Minimum Information Rate. The minimum data rate for a VC that

the router throttles down to when it is noti®ed of congestion.

Maximum Info Rate

Maximum Information Rate. The maximum data rate at which the

router transmits for a VC.

Required

Yes or No. If yes, the PVC is a Required PVC.

PVC group name

If the PVC is a member of a required PVC group, the name

appears here; otherwise, ªUnassignedº appears.

Compression capable

Indicates whether the circuit can compress data packets.

Operational

Indicates whether compression is active on the circuit. When this is

yes, data is being compressed on this link.
