WAN Logical View Window Fields
IF
Displays the interface index; a unique value for each interface that this device
connects to.
Protocol
Displays the active Link Layer protocol. This Þeld displays PPP (Point to Point),
Frame Relay, or Other.
Compression
Indicates whether data compression is activated or de-activated.
MTU
Displays the MTU (Maximum Transfer Unit) for this interface. The MTU is the
largest packet size that can be transmitted on the selected interface.
Line Coding
Displays the line coding set for this interface. The Þeld displays INV-HDLC, JBZS,
or None. None (the default value) is displayed when the line coding being used
on the interface is B8ZS.
CRC Length
The length of the CRC (Cyclical Redundancy Check) for this interface.
Changing WAN Logical Settings
You can change the protocol setting, from your WAN Logical View window.
To do so:
1. Click anywhere on the line of the interface of interest, and the WAN Logical
Settings window (Figure 3-2) will appear.
NOTE
Data compression is not supported by the CSX at this time; therefore, compression will
always be de-activated or ÒOffÓ.
