Are the switch MAC address entries matching destination MAC addresses of packets aged out

In V100R005 and earlier versions, by default, MAC address entries are aged out no matter whether the entries match destination MAC addresses of packets. To resolve network problems, modify the V100R005SPH007 patch as follows: The aging time is recalculated for the MAC address entries to be aged out when the entries match destination MAC addresses of packets. In V100R006 and later versions, by default, the aging time is recalculated for the MAC address entries to be aged out when the entries match destination MAC addresses of packets.

NOTE:
This command is used only when one-way services are deployed on the network. Packets of two-way services are transmitted bidirectionally; therefore, dynamic MAC address entries match both the source MAC addresses and destination MAC addresses of packets and are not aged.
When a user uses one-way services such as the 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 one-way packets. Therefore, the destination MAC address of the packets matches the MAC address entry and the MAC address is never aged out.
