6–8 MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL
ACCESS CONSIDERATIONS CHAPTER 6: ACCESS CONSIDERATIONS
Example 6-5 illustrates these steps for setting up port security on a specific port:
Once port security is setup, it is important to manage the log and review the log often. If
the signals are sent to the trap receiver, the traps should also be reviewed for intrusion and
other infractions.
6.2.2 Security Logs
All events occurring on the MultiLink family of switches are logged. The events can be
informational (e.g. login, STP synchronization etc.), debugging logs (for debugging network
and other values), critical (critical events), activity (traffic activity) and fatal events (such as
