function.
Syntax
clear port_security_entry port <portlist>
Description This command is used to clear MAC address entries which were learned by the Switch
by a specified port. This command only relates to the port security function. This
command will only take effect if the lock address mode set using the config
port_security ports command is set as permanent or delete on reset.
Parameters
<portlist> − Specifies a port or port range to clear. The port list is specified by listing the
lowest switch number and the beginning port number on that switch, separated by a
colon. Then the highest switch number, and the highest port number of the range (also
separated by a colon) are specified. The beginning and end of the port list range are
separated by a dash. For example, 1:3 specifies switch number 1, port 3. 2:4 specifies
switch number 2, port 4. 1:3–2:4 specifies all of the ports between switch 1, port 3 and
switch 2, port 4 − in numerical order. Non–contiguous portlist entries are separated by a
comma. (ex: 1:1–1:3,1:7–1:9)
