■ Filtering address
Filtering addresses are manually added and determine the packets with specific source or
destination MAC addresses that will should dropped by the switch.
Security Configurations
■ Configuring MAC Notification Traps
You can configure traps and SNMP (Simple Network Management Protocol) to monitor and
receive notifications of the usage of the MAC address table and the MAC address change
activity. For example, you can configure the switch to send notifications when a new MAC
address is learned, so the administrator knows a new users accesses the network.
■ Limiting the Number of MAC Addresses in VLANs
You can configure VLAN Security to limit the number of MAC addresses that can be
learned in specified VLANs. The switch will not learn addresses when the number of
learned addresses has reached the limit, preventing the address table from being used up
by broadcasting packets of MAC address attacks.
