Parameters
count
: Specifies the maximum number of MAC addresses that can be learned on an interface.
When the argument is set to 0, the interface is not allowed to learn MAC addresses. The value range
for this argument is 0 to 4096.
Usage guidelines
This command helps limit the MAC address table size. When the number of MAC address entries
learned by an interface reaches the limit, the interface stops learning MAC address entries.
Examples
# Configure GigabitEthernet 1/0/1 to learn a maximum of 600 MAC address entries.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
