H3C S9500 Series Routing Switches
The Ethernet switch also provides the function of MAC address aging. If the switch
receives no packet for a period of time, it will delete the related entry from the MAC
address table. However, this function takes no effect on the static MAC addresses.
You can configure (add or modify) the MAC address entries manually according to the
actual networking environment. The entries can be static ones or dynamic ones.

tasks.

2.2.1 Setting MAC Address Table Entries
Administrators can manually add, modify, or delete the entries in MAC address table
according to the actual needs. They can also delete all the (unicast) MAC address table
entries related to a specified port or delete a specified type of entries, such as dynamic
entries or static entries.
You can use the following commands to add, modify, or delete the entries in MAC
address table.
Perform the following configuration in system view.

2.2.2 Setting MAC Address Aging Time
The setting of an appropriate aging time can effectively implement the function of MAC
address aging. Too long or too short aging time set by subscribers will cause the
problem that the Ethernet switch broadcasts a great mount of data packets without
MAC addresses, which will affect the switch operation performance.
