Mac-Address Mac-Learning Disable - H3C S7500E Series Command Reference Manual

Description
Use the mac-address command to add or modify a MAC address entry.
Use the undo mac-address command to remove one or all MAC address entries.
Note that:
A static or blackhole MAC address entry will not be overwritten by a dynamic MAC address entry,
but a dynamic MAC address entry can be overwritten by a static or blackhole MAC address entry.
If you execute the undo mac-address command without specifying any parameters, this
command deletes all unicast MAC address entries and static multicast MAC address entries.
You can delete all the MAC address entries (including unicast MAC address entries and static
multicast MAC address entries) of a VLAN, or you can choose to delete its dynamic, static, or
blackhole MAC address entries only. You can single out some ports and delete the corresponding
unicast MAC address entries, but not the corresponding static multicast MAC address entries.
As your MAC address entries configuration cannot survive a reboot, save it after completing the
configuration. The dynamic entries however will be lost whether you save the configuration or not.
Related commands: display mac-address.
