learning. Be sure you enable the learning function long enough to ensure
that all valid VLAN members have been registered on the selected port.
Note that you can also restrict the maximum number of addresses that can
be learned by a port.
To add new VLAN members at a later time, you can manually add secure
addresses with the Static Address Table (page 3-140), or turn off port
security to reenable the learning function long enough for new VLAN
members to be registered. Learning may then be disabled again, if desired,
for security.
