MAC STUDY AND AGING
This section allows the network administrator to specify the maximum amount of MAC addresses that can be
learned per port, the default interface maximum being 8191 addresses. Interface maximums cannot exceed
the device maximum, which is also 8191.
Item Description
Ports Select one or multiple ports for which you want to dene the MAC address study limit

study limit
Key in the maximum MAC address limit for the selected port(s).
The Intellinet Network Solutions switch also provides a mechanism to adjust the aging time for stored MAC
addresses. The aging time controls how long the switch keeps storing the MAC address in the MAC address
table. Every time a client sends or receives trac, the aging time for the client’s MAC address is reset. If there
is no trac for a MAC address in a time frame that exceeds the time dened in the aging time eld, the MAC
address is removed from the MAC address table. The default aging time is 300 seconds. Setting the value
to “0” disables the aging time mechanism, which means that the MAC address table will keep the learned
address until the switch is reset. Since the Intellinet Network Solutions switch has only nite space to hold
MAC addresses, it is recommended to keep the aging time at or around the default value.
MAC FILTER
With this feature the network administrator can prevent access to the network for selected MAC addresses
and VLAN IDs (1 = default VLAN).
Item Description
MAC Address Type in the MAC address that you want to block.
