Configuration Guide
MAC Address Configuration
By configuring the static address manually, you can bind the MAC address for
the network device with the interface in the MAC address table.
Filtering Address
A filtering address is a manually configured MAC address When the device
receives the packets from a filtering address, it will directly discard them. You
can only manually add and delete a filtering address rather than age it out. A
filtering address is stored in the configuration file and will not be lost even if the
device restarts.
If you want the device to filter some invalid users, you can specify their MAC
addresses as filtering addresses. Consequently, these invalid users cannot
communicate with outside through the device.
Caution
A filtering address is invalid for the packets sent to the CPU. For
example, the L2 source MAC address for an ARP packet is a
filtering address, this ARP packet can still be sent to the CPU,
but can not be forwarded.
MAC Address Change Notification
The MAC address notification function is an effective way to let you know user
changes for the devices in a network.
Figure-13 MAC address Change Notification
After the MAC address change notification is enabled, the MAC address
change notification infornation is generated and sent in the SNMP Trap
message form to the specified NMS when the switch learns a new MAC
address or ages out a learned MAC address.
The notification about adding a MAC address lets you know a newcomer
(identified by the MAC address) is using the device. The notification about
deleting a MAC address (in the case of that the user did not communicate with
