address entry has an aging timer. When the device receives a packet with the source or destination MAC
address matching a dynamic MAC address entry, it restarts the aging timer for the entry.
If you want the device to restart the aging timer of dynamic entries for only matching source MAC
addresses, disable MAC entry aging timer refresh based on destination MAC address.
