Use the x25 switch svc xot command to add an X.25 switching route whose 
forwarding address is XOT channel.

Use the undo x25 switch svc xot command to delete the specified X.25 
switching route.

By default, no X.25 switching route is configured.

After configuring the XOT switching command of X.25 SVC, a user can cross IP 
network from the local X.25 network to implement the interconnection with the 
remote X.25 network. If a user configures the keepalive attribute, the link 
detection for XOT will be supported.

# Configure a XOT route and forward the packet whose destination X.121 address 
is 1 to the destination address whose IP address is 10.1.1.1.

Use the x25 switching command to enable the X.25 switching function.

Use the undo x25 switching command to disable this function, which will not 
affect the established VC switching.

By default, X.25 packet switching function is disabled.

X.25 packet switching is used to accept packets from an X.25 interface and send 
them to a certain interface based on the destination information contained in the 
packets. The device with this function can be used as a small-sized packet switch.

Table 71   XOT channel parameter option

keepalive packet upon timeout to detect the connection 
availability. Its value ranges from 1 to 3600. 

retry times 

Number of maximum retries of sending keepalive. If the number 
exceeds times, the XOT connection will be disconnected. Its value 
ranges from 3 to 3600.
