of switch connects are fixed, that is, the interface that each device
MAC address in switch MAC address table corresponds is fixed,
then make the mac address that learns from port and will learn
from port permanent to prevent MAC deceiving format network
attack. Even if after device is rebooted, these MAC addresses still
can be used. Of course, the premise is that automatic writing
function is opened or write operation is implemented.
MAC address permanent means making dynamic MAC address of
corresponding port in MAC address table permanent. After this
configuration, the MAC address learns from the corresponding port
can convert to permanent automatically. These MAC addresses
don't join aging after converting and can be saved into disk. Mean-
while if data frame with this source address occurs on other ports
switch won't learn again. The MAC permanent entry number is lim-
ited. Therefore when the newly learned MAC entry on port can't
continue converting, alarm will occur and subsequent MAC will still
be handled as dynamic entry. When this function is disabled, all
MAC entries converted by this way on this port will be deleted.
To configure MAC address permanent, perform the following com-
mands.
