Configuring the WAN
The following example configures the asynchronous serial interface on NIM 2, port 0 with the
following non-default values: PPP encapsulation, RS422 cabling, 57600 bps clock rate, MTU size of
1200 bytes, no parity, 7 databits and 2 stopbits. It also assigns the local IP address 192.168.1.1 to the
interface. Although the XSR is not designed to be an access server, you can attach an external
modem to the serial port and accept async calls as long as the modem is configured in "dumb
mode" (AT commands are disabled).
XSR(config)#interface serial 2/0
XSR(config-if<S2/0>)#ip address 192.168.1.1 255.255.255.0
XSR(config-if<S2/0>)#encapsulation ppp
XSR(config-if<S2/0>)#physical-layer async
XSR(config-if<S2/0>)#media-type rs422
XSR(config-if<S2/0>)#clock rate 57600
XSR(config-if<S2/0>)#ip mtu 1200
XSR(config-if<S2/0>)#parity none
XSR(config-if<S2/0>)#databits 7
XSR(config-if<S2/0>)#stopbits 2
XSR(config-if<S2/0>)#no shutdown
The following example configures the XSR to dial-out (async):
XSR(config)#interface serial 1/0
XSR(config-if<S2/0>)#encapsulation ppp
XSR(config-if<S2/0>)#physical-layer async
XSR(config-if<S2/0>)#dialer pool-member 1
XSR(config-if<S2/0>)#clock rate 57600
XSR(config-if<S2/0>)#no shutdown
XSR(config-if<S2/0>)#interface dialer1
XSR(config-if<D1>)#dialer pool 1
XSR(config-if<D1>)#dialer string 015081234567
XSR(config-if<D1>)#encapsulation ppp
XSR(config-if<D1>)#ip address 192.168.1.2 255.255.255.0
XSR(config-if<D1>)#no shutdown
