mac-address max-mac-count (Interface view)
Syntax

Default Level
2: System level
Parameters
count : Maximum number of MAC addresses that can be learned on a port, ranging from 0 to 4096.
When the argument takes 0, the VLAN is not allowed to learn MAC addresses.
disable-forwarding : Disables forwarding of frames with unknown source MAC addresses after the
number of learned MAC addresses reaches the upper limit. Frames with the source MAC addresses
listed in the MAC address table will be forwarded normally.
Description
Use the mac-address max-mac-count count command to configure the maximum number of MAC
addresses that can be learned on an Ethernet port.
Use the undo mac-address max-mac-count command to restore the default maximum number of
MAC addresses that can be learned on an Ethernet port.
By default, the maximum number of MAC addresses that can be learned on an Ethernet port is not
configured.
If the command is executed in interface view, the configuration takes effect on the current interface; if
the command is executed in port group view, the configuration takes effect on all ports belonging to the
port group.
