mac-address
max-mac-count
Syntax

undo mac-address max-mac-count
View
Ethernet port view
Parameter
count: Enter to specify how many MAC addresses a port can learn. This can be in
the range 0 to 32768. 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.
Related commands: mac-address, mac-address timer, mac-address
mac-learning disable
Examples
To configure the port “Ethernet 1/0/3” to learn at most 600 MAC addresses, enter
the following:
[SW7700-Ethernet1/0/3]mac-address max-mac-count 600
To cancel the maximum limit on the number of MAC addresses learned by the port
“Ethernet1/0/3”, enter the following:
[SW7700-Ethernet1/0/3]undo mac-address max-mac-count
