Parameters
count: Sets the maximum number of MAC addresses that can be learned on a VLAN. The value
range is 0 to 1048576. When the argument takes 0, the VLAN is not allowed to learn MAC
addresses.
Usage guidelines
This command limits the number of MAC address entries for a device. As the MAC address table is
growing, the forwarding performance of your device may degrade. When the number of MAC
address entries learned by a VLAN reaches the limit, the VLAN stops learning MAC address entries.
Examples
# Configure VLAN 10 to learn up to 600 MAC address entries.
<Sysname> system-view
[Sysname] vlan 10
[Sysname-vlan10] mac-address max-mac-count 600
