MAC Address Table Management Commands 337
undo mac-address max-mac-count
View
Ethernet port view
Parameter
count: Enter a value in the range 0 to 32768 to specify how many MAC
addresses a port can learn. 0 means that the port is not allowed to learn MAC
addresses.
Description
Use the mac-address max-mac-count command to configure the maximum
number of MAC addresses that can be learned by a specified Ethernet port. The
port stops learning MAC addresses when the specified limit is reached.
Use the undo mac-address-table max-mac-count command to cancel the
maximum limit on the number of MAC addresses learned by an Ethernet port. This
is the default. If you set no maximum limit, the MAC address table controls the
number of MAC addresses a port can learn.
