MAC Address-Based Security

The MAC address-based security feature allows you to set up network access control, based on source MAC addresses of authorized stations.

You can:

•Create a list of up to 448 MAC addresses and specify which addresses are authorized to connect to your switch or stack configuration. The 448 MAC addresses can be configured within a single standalone switch or they can be distributed in any order among the units in a single stack configuration.

•Specify which of your switch ports each MAC address is allowed to access.

The options for allowed port access include: NONE, ALL, and single or multiple ports that are specified in a list, for example, 1/1-4,1/6,2/9 (see “Port List Syntax” on page 3-34).

•Specify optional actions to be exercised by your switch if the software detects a security violation.

The response can be to send a trap, turn on destination address (DA) filtering, disable the specific port, or any combination of these three options.

For instructions on using the console interface (CI) to set up network access control, see “MAC Address-Based Security” on page 3-23.

The MAC address-based security feature is based on Nortel Networks BaySecure™ LAN Access for Ethernet, a real-time security system that safeguards Ethernet networks from unauthorized surveillance and intrusion.
