Compression
Indicates whether data compression is activated or de-activated.You can choose
ÔOnÕ to activate compression or ÔOffÕ to de-activate it.
Lex Status
Indicates if the interface has connected to a Cisco router using the Lex protocol. If
a connection has been made, the Þeld will display Bound; if a connection has not
been made, the Þeld will display UnBound; if the interface does not support Lex
Protocol the Þeld will display NotSupp.
Configuring the WAN Interfaces
You can conÞgure the WAN Interfaces as follows:
1. Use the Set Selection button to specify the scope of interfaces to which
configuration changes will apply:
a. Choose Selected Interfaces to apply changes only to those interfaces
highlighted in the scroll list.
Click mouse button 1 to highlight one or more interfaces in the list. Use
the scroll bar, if necessary, to scroll through the available interfaces.
b. Choose All Interfaces to apply changes to all WAN interfaces on the
device.
2. To change the Protocol Selection, click on the selection box; a pull-down
menu will appear. Select None, PPP, or Frame Relay, as appropriate.
3. To alter the MTU, highlight the current MTU value, and type in a new value
from 128 to 8191 in the text box.
Note that if you do not change the current MTU value, a default MTU will
appear in accordance with your Protocol Selection (4095 for Frame Relay;
8191 for PPP).
NOTE
Data compression is not supported by CSX Þrmware at this time; therefore, compression
will always be de-activated or ÒOffÓ.
NOTE
The CSX does not currently support PPP/Lex protocol; therefore the Lex Status Þeld will
always display NotSupp (Not Supported).
