Utilizing the Command Line Interface
2-2 Managing the XSR
Using the Console Port to Remotely Control the XSR
The XSR’s Console port can also be connected to a modem for the purpose of remote console
control. Make the connection with a straight-through cable and enter the following XSR commands:
XSR(config)#interface serial 0
XSR(config-if<S0>)#physical-layer async
XSR(config-if<S0>)#clock rate 9600
XSR(config-if<S0>)#encapsulation ppp
XSR(config-if<S0>)#ip address 192.168.10.1 255.255.255.0
XSR(config-if<S0>)#ppp timeout retry 20
XSR(config-if<S0>)#no shutdown
Set the modem switches as follows:
• DTR override (DTR is ignored)
• No echo offline commands
• Auto answer on first ring
• Carrier Detect normal
• Load factory defaults
• Dumb mode (AT command mode disabled
Connecting a Serial Interface to a Modem
The XSR supports attaching a Serial (RS-232) NIM interface and modem to accept inbound and
outbound data calls. Modem switches and the receiving-side XSR are configured exactly as
described in “Using the Console Port to Remotely Control the XSR” except that the
interface
serial 0
command must instead specify interface serial 1 (or higher). Straight-through
cabling is required again for the connection.
On the calling-side XSR, enter the following commands:
XSR(config)#interface serial 1/1
XSR(config-if<S1/1>)#physical-layer async
XSR(config-if<S1/1>)#clock rate 38400
XSR(config-if<S1/1>)#encapsulation ppp
XSR(config-if<S1/1>)#dialer pool-member 1
XSR(config-if<S1/1>)#no shutdown
XSR(config-if<S1/1>)#dialer interface 1
XSR(config-if<D1>)#dialer pool 1
XSR(config-if<D1>)#dialer string <your phone number>
XSR(config-if<D1>)#address 192.100.10.2 255.255.255.0
XSR(config-if<D1>)#no shutdown
And enter the following calling-side modem switch settings:
• DTR normal (DTR disconnects)
• Echo offline commands
• Verbal result codes
• Display result codes
• Carrier Detect normal
• AT command mode enabled
