DDR Configuration
1-82
z Add in the remote router, the dialer map corresponding to local router network
layer address.
z Remove all the dialer maps in the remote configuration, and use dial string
instead.
DDR: link negotiation Down on interface ***
This debugging information may be generated by the following caus es: incorre ct PP P
configuration, so that PPP consulting fails and thus the connection is hook ed on.
The solution is: configure with reference of the example above.
DDR: NAME authentication ERROR failed
This debugging information may be generated by the following causes: the nam e
(dialer remote-name, name in dialer map) configured by DDR is inconsistent with the
name configured in PPP, local DDR authentication fails to pass thus this connection is
hooked on.
The solution is: configure with reference of the example above.
DDR: peeraddr matching error on interface *** shutdown lin k
This debugging information may be generated by the following cause: there is no
remote network layer address in the local dialer map.
The solution is: add in the local router, the dialer map corresponding to remote network
layer address, or remove all the dialer maps in the local configur ation, and use dial
string instead.
DDR:idle-timeout on interface *** shutdown! start enable-time
This debugging information does not indicate any error, instead, it means that the local
DDR idle-timeout time is timeout and DDR hooks on the connection normally.
DDR: wait-for-carrier-timeout on a link on interface *** shutdown!start
enable-time
This debugging information may be generated by the followin g cause: local router fails
to dial and connect the opposite end, because the opposite end is busy or te lephone
line quality is poor.
DDR: The interface has no dialer-group discard the packet !
This debugging information may be generated by the following cause: dialer-group
configuration command is not configured on the corresponding logical dial interface or
on the physical port directly enabling DDR.
The solution is: configure with reference of the example above.
DDR: there is not a dialer string on the interface failed disca rd packet
This debugging information may be generated by the following cause: dialer-map is not
configured on the corresponding logical dialer interface or on the physical por t dir ect l y
enabling DDR, and no dial string is configured.
The solution is: configure dialer map and dial string locally accordin g to the c a lls t o be
sent by local end.
DDR: Enable-timeout is effective failed
This debugging information does not indicate any error, instead, it is because t hat th e
enable-timeout timer of the corresponding physical port is not yet timeout. When the
timer is timeout, the corresponding physical port can be used to dial.
