Deleting the Port Security Database
switch# port-security database copy vsan 1
Use the port-security database diff active vsan command to view the differences between the active database
and the configuration database. This command can be used when resolving conflicts.
switch# port-security database diff active vsan 1
Use theport-security database diff config vsan command to obtain information on the differences between
the configuration database and the active database.
switch# port-security database diff config vsan 1
Tip
We recommend that you issue the port-security database copy vsan command after disabling auto-learning.
This action will ensure that the configuration database is in sync with the active database. If distribution is
enabled, this command creates a temporary copy (and consequently a fabric lock) of the configuration database.
If you lock the fabric, you need to commit the changes to the configuration databases in all the switches.
Deleting the Port Security Database
Tip If the distribution is enabled, the deletion creates a copy of the database. An explicit port-security commit
command is required to actually delete the database.
Use theno port-security database vsan command in configuration mode to delete the configured database
for a specified VSAN
switch(config)# no port-security database vsan 1
Cleaning the Port Security Database
Use the clear port-security statistics vsan command to clear all existing statistics from the port security
database for a specified VSAN.
switch# clear port-security statistics vsan 1
Use the clear port-security database auto-learn interface command to clear any learned entries in the
active database for a specified interface within a VSAN.
switch# clear port-security database auto-learn interface fc1/1 vsan 1
Use the clear port-security database auto-learn vsan command to clear any learned entries in the active
database for the entire VSAN.
