Parameter
alarm: when the current number of MAC addresses exceeds the threshold value,
whether the switch gives the network administrator an alarm or not. By default, the
switch doesn't give an alarm.
Description
Use the mac-address max-mac-count enable { alarm | forward }* command to
enable the switch to send alarms to network administrator.
Use the undo mac-address max-mac-count enable { alarm | forward }* command to
disable the function.
After the mac-address max-mac-count enable { alarm | forward }* command is
executed, if the MAC addresses learned by a port reach the maximum number of MAC
addresses that the port can learned, the port will send an alarm to network
administrator to prompt that the port will no longer learn any MAC addresses.
Related commands: mac-address, mac-address timer.
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.
Example
# Set the maximum number of MAC addresses learned by Ethernet port Ethernet3/1/3
to 600, and the switch will give an alarm to the network administrator and forward the
packets when the number of MAC addresses learned exceeds 600.
