Parameter
count: Maximum number of MAC addresses learned by a port, ranging from 0 to 14,336,
the value of 0 means that address learning is disabled.
Description
Use the mac-address max-mac-count command to set the maximum number of MAC
addresses learned by an Ethernet port.
Use the undo mac-address max-mac-count command to remove the limit on the
maximum number of MAC addresses learned by an Ethernet port.
By default, a port can learn as many MAC addresses as a board can have. You can
change the default value by using this command: if you set the value to count, and
when the number of MAC addresses learned by the port reaches this value, this port
will no longer learn any more MAC addresses; and you can use the undo
mac-address max-mac-count command to remove the limit on the number.
Note:
The maximum number of MAC addresses of a board ranges from 12 K to 16 K
depending on various software versions and board types.
The aforementioned number of MAC addresses includes only the MAC addresses
learned by the switch dynamically, and excludes those configured by the user.
When executing the mac-address max-mac-count command, if the current
number of MAC addresses exceeds the threshold value, the switch neither delete
the present MAC address entries nor learn new MAC address until the number of
entries less than the threshold value after some entries are aged out.
Related command: mac-address and mac-address timer.
Example
Set the maximum number of MAC addresses learned by Ethernet port Ethernet3/1/3 to
600.
