Enabling MAC Address Learning

MAC address learning is enabled on all switch ports by default.
Ports can learn MAC addresses freely. The device can bind MAC
addresses to a port (configure these addresses manually) when
these devices will always be connected to that port. Disable MAC
address learning so that the port will no longer learn MAC ad-
dresses.
To enable MAC Address learning on a port, use the following com-
mand.

Limiting MAC Address Count

When there are too may users online and MAC address table size
is near its upper limit, the count of MAC addresses learned by low
priority user ports can be limited.
Limiting the MAC address count of a port is a good countermeasure
against MAC address flood attacks.
For limiting MAC Address count on a port, perform the following
steps.
MAC address count is unlimited by default. To cancel MAC address
count limit, set the limit to 0.
Function
When adding MAC address, if
the VLAN ID is not designated
, add according to port PVID.
If a VLAN ID is not specified
while deleting a MAC
address, all entries matching
<mac-address>will be
deleted.
Function
This enables MAC address
learning on a port.
Function
This limits MAC address count
on a port.
