Chapter 3 Configuring Remote Access to MPLS VPN
Monitoring and Maintaining RBE to MPLS VPN
Caution Because debugging output is assigned high priority in the CPU process, it can render the system
unusable. For this reason, use debug commands only to troubleshoot specific problems or during
troubleshooting sessions with Cisco Systems technical support personnel. Moreover, it is best to use
debug commands during periods of lower network traffic and fewer users. Debugging during these
periods decreases the likelihood that increased debug command processing overhead will affect system
use.
Note For more information, see the “Troubleshooting DSL Access to MPLS VPN Integration” chapter in the
Troubleshooting Cisco Remote Access to MPLS VPN Integration, Release 2.0.
Monitoring and Maintaining RBE to MPLS VPN
To monitor and maintain RBE to MPLS VPN environments, enter any of the following commands in
privileged EXEC mode:
Router# debug radius
Displays information associated with the Remote Authentication
Dial-In User (RADIUS) server.
Router# debug vpdn pppoe-events
Displays PPPoE protocol errors that prevent a session from being
established or errors that cause an established session to be
closed.
Router# debug vtemplate
Displays cloning information for a virtual access interface from
the time it is cloned from a virtual template to the time the virtual
access interface comes down when the call ends.
Command Purpose
Command Purpose
Router# show atm map
Displays the list of all configured ATM static maps to remote
hosts on an ATM network and on ATM bundle maps.
Note This command enables you to confirm the configuration
of the map statements in a static map. This command is
useful when an encapsulation failure occurs on a packet
because a Layer
3 address could not be mapped to a
corresponding Layer 2 address.
Router# show atm vc
Displays all ATM PVCs, SVCs, and traffic information.
Router# show interfaces atm interface
Displays information about the ATM interface.
Router# show ip arp vrf name
Displays the Address Resolution Protocol (ARP) cache
associated with a VRF.
Router# show ip route vrf name
Displays the IP routing table associated with a VRF.
