CSX WAN Configuration

State

Indicates whether the selected virtual circuit is operational. If the circuit is active,
it is considered operational. If the circuit is labeled inactive then the circuit is
temporarily disabled, but still has the capability of being active. If the state of the
circuit is invalid, then the circuit is not operational. You can temporarily disable a
circuit by changing the state to Ôinactive.Õ The default state is Ôactive.Õ

Create

Displays the value of the sysUpTime when the virtual circuit was created,
whether by the Data Link Connection Management Interface or by a SetRequest.

LastChange

Display the value of sysUpTime when last there was a change in the virtual circuit
state.

CommittedBurst (B

c

)

Indicates the maximum amount of data, in bits, that the network agrees to
transfer under normal conditions, during the committed time interval Ñ T

c

. You

can change the value of this Þeld from this window. The default value is 0, which
signiÞes no commitment.

ExcessBurst

Indicates the maximum amount of uncommitted data bits that the network will
attempt to deliver over the committed time interval T

c

. Excess burst data is

eligible to be discarded if the network is experiencing congestion. You can change
this value from this window. If you do not conÞgure this Þeld, the default is the
value is ifSpeed.

CIR (Committed Information Rate)

The Committed Information Rate (CIR) is the subscriber data rate (expressed in
bits/second) that the network commits to deliver under normal network
conditions. CIR is averaged over the committed time interval T

(CIR = B
