the port you choose
3
Set the maximum
number of MAC
addresses learned
by an Ethernet port
[SW8800-EthernetX/1/
X]
mac-address
max-mac-count
count
or
[SW8800-GigabitEther
netX/1/X]
mac-address
max-mac-count count
By default, the
switch has no limit
on the maximum
number of MAC
addresses learned
by a port
4
Set the switch to
drop the packets
whose source MAC
addresses are not
learned by the port
when the number of
MAC addresses
learned exceeds the
threshold value
[SW8800-EthernetX/1/
X]
undo mac-address
max-mac-count
enable forward
or
[SW8800-GigabitEther
netX/1/X]
undo
mac-address
max-mac-count
enable forward
By default, the
switch forwards
packets whose
source MAC
addresses are not
leaned by the port
when the number of
MAC addresses
learned exceeds
the threshold value
