CHAPTER 6: ACCESS CONSIDERATIONS

CONFIGURING PORT SECURITY THROUGH THE COMMAND LINE INTERFACE

MULTILINK ML1600 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL

6–7

(Optional step) Add any specific MAC addresses, if needed, to allow
designated devices to access the network (use the

add

mac=00:c1:00:7f:ec:00 port=11,15

command).

Disable access to the network for unauthorized devices (Use

action port=11 <diable|drop>

depending on whether the

port should be disabled or the packed dropped. Follow that with a

show port-security

command to verify the setting).

(Optional step) Set the notification to notify the MGMNT station on
security breach attempts (use the command

signal port

make a log entry or send a trap).
