25.1.5 Registering Static Entries
In addition to dynamic learning by received frame, MAC addresses can be registered statically by user specification. One port or channel group can be specified for a unicast MAC address. Also, frames can be specified for discarding, instead of specified for a port, in which case frames for the specified destination MAC address or source MAC address are discarded without being forwarded to any port.
When a unicast MAC address is statically registered, dynamic learning is not performed for the address. Already learned entries are deleted from the MAC address table and registered as static entries. Also, any frames whose source is the specified MAC address are discarded when received from outside the port or channel group. The following table describes the parameters specified for static entries.
