Parameters

count: Specifies the maximum number of MAC addresses that can be learned for a VLAN. When the argument is set to 0, the VLAN is not allowed to learn MAC addresses. The value range for this argument is 0 to 4096.

Usage guidelines

This command limits the number of MAC address entries to limit the MAC address table size. A large MAC address table will degrade forwarding performance. 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 a maximum of 600 MAC address entries.

<Sysname> system-view
[Sysname] vlan 10
[Sysname-vlan10] mac-address max-mac-count 600
