Tips
If you are having trouble:
•
•
Enter the show interface command and make sure the line protocol is up and you are using the
correct IP interface. Also, make sure that excessive errors are not being reported.

Make sure the serial interface and protocol are up by entering the show interface serial
command. Also, check the IP address.

Enter the debug dialer command to view the error messages (Table 3-14). You can also use the
debug dialer events or debug dialer packets messages to view event or packet messages. When
you finish viewing the messages, enter the no debug dialer command to turn off the messages.
5300# debug dialer
PRI0: Dialing cause: PRI0: ip PERMIT
PRI0: No dialer string defined.
PRI0: Dialing cause: PRI0: ip PERMIT
Using address of FastEthernet0 (15.0.0.60)
Dialing cannot occur..
