mac-address destination hit aging enable
Function
The mac-address destination hit aging enable command configures the device to age MAC address entries no matter whether the entries match destination MAC addresses of packets.
The undo mac-address destination hit aging enable command restores the default configuration.
By default, if MAC address entries match destination MAC addresses of packets, the system recalculates the aging time.
S5735-L, S5735S-L, S5735S-L-M, S5735-S, S5735-S-I, and S5735S-S do not support this command.
Usage Guidelines
Usage Scenario
When a user uses one-way services such as the video on demand service, packets are transmitted unidirectionally from the server to the user terminal. When the user terminal is shut down, the server still sends packets. Therefore, the dynamic MAC address entry with the destination MAC address of the packets remains in the MAC address table.
To delete MAC address entries matching one-way service packets after user terminals are shut down, run the mac-address destination hit aging enable command to enable the device to age dynamic MAC address entries matching dynamic MAC addresses of received packets.
Configuration Impact
This command is used only when one-way services are deployed on a network.
Precautions
This command only free up space in the MAC address table but cannot save system resources. If the device cannot find the matching entry in the MAC address table, it broadcasts the packets.
