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.
