Interface Monitoring:
1. Copy packets to local interface for monitoring
2. Packets entering or exiting an interface (up tp 256 interfaces)

VLAN Monitoring:
1. Copy packets to a analyzer VLAN for remote monitoring
2. Packets entering VLAN (up to 256 vlan‟s)

Policy:

The lower the #, the more serious the event!
The system will log messages at specific “severity” level AND at ALL more serious
levels!
IF we log at level “warning”, we not only log warning, but also log 3, 2, 1 and 0 levels.
If we wish to NOT log a specific level, then we use the “facility” and “none” option.

Kill area 5 physical connection…. ( kill the 172.16.5.0 network ).
On the “Phillies” router, user the “monitor start messages” command.
Essentially, this network failure will cause ospf to converge and hence run spf calculations.
