Committed Information Rate (CIR)
This field sets the Committed Information Rate (CIR) for this virtual circuit. See Congestion
Control on page 29-8 for further information on the CIR.
♦ Important Note ♦
The
CIR that you enter must match that used by your
service provider. This option should only be modified
by experienced Frame Relay network administrators.
Committed Burst Size (Bc)
The Committed Burst Size (BC) is the amount of data that the network will guarantee to trans-
fer under normal conditions. See Congestion Control on page 29-8 for further information.
♦ Important Note ♦
The
Committed Burst Rate that you enter must match
that used by your service provider. This option should
only be modified by experienced Frame Relay network
administrators.
Excess Burst Size (Be)
The Excess Burst Size (Be) is the amount of data over-and-above the Committed Burst Size
(BC) that the network will transmit as long as excess bandwidth is available. See Congestion
Control on page 29-8 for further information.
♦ Important Note ♦
The
Excess Burst Rate that you enter must match that
used by your service provider. This option should only
be modified by experienced Frame Relay network
administrators.
Compression Administrative State
This field enables and disables compression negotiation for this virtual circuit. If set to enable,
then the
WSX will query the Bridge/Router on the other end of the Frame Relay link as to
whether it supports compression. Compressed data will be sent only when the other Bridge/
Router also supports compression. If the Bridge/Router on the other end is an Omni Switch/
Router, then data would be sent compressed as long as you set the Compression Administra-
tive State to Enabled.
Disabling Compression Administrative State means that data will not be sent compressed even
if the other Bridge/Router supports compression. Data compression is always negotiated
before it is activated.
