Troubleshooting RPM/VPDN Connection
The following sample output from the debug resource-pool command displays a successful
RPM/VPDN connection. The entries in bold are of particular importance.
*Mar 1 00:15:53.639: Se0:10 RM/VPDN/rm-session-request: Allocated vpdn info for domain

Troubleshooting Customer/VPDN Profile
The following sample output from the debug resource-pool command displays when there is no VPDN
group associated with an incoming DNIS group. However, the output from the debug resource-pool
command, as shown here, does not effectively reflect the problem:
*Mar 1 03:40:16.483: Se0:15 RM/VPDN/rm-session-request: Allocated vpdn info for domain
NULL MLP Bundle SOHO
*Mar 1 03:40:16.515: Se0:15 RM/VPDN/rm-session-request: Authorization failed
*Mar 1 03:40:16.527: %VPDN-6-AUTHORERR: L2F NAS HQ-NAS cannot locate a AAA server for
Se0:15 user SOHO
*Mar 1 03:40:16.579: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to up
*Mar 1 03:40:17.539: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0:15, changed
state to up
*Mar 1 03:40:17.615: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access1,
changed state to up
*Mar 1 03:40:19.483: %ISDN-6-CONNECT: Interface Serial0:15 is now connected to SOHO
Whenever the debug resource-pool command offers no further assistance besides the indication that
authorization has failed, enter the debug aaa authorization command to further troubleshoot the
problem. In this case, the debug aaa authorization command output appears as follows:
*Mar 1 04:03:49.846: Se0:19 RM/VPDN/rm-session-request: Allocated vpdn info for domain
