Port Security
– 640 –
addresses when it reaches a configured maximum number. Only
incoming traffic with source addresses already stored in the dynamic or
static address table will be accepted.
◆
First use the port security max-mac-count command to set the
number of addresses, and then use the port security command to
enable security on the port. (The specified maximum address count is
effective when port security is enabled or disabled.)
◆
Use the no port security max-mac-count command to disable port
security and reset the maximum number of addresses to the default.
◆
You can also manually add secure addresses with the
command.
◆
A secure port has the following restrictions:
■
Cannot be connected to a network interconnection device.
■
Cannot be a trunk port.
◆
If a port is disabled due to a security violation, it must be manually re-
enabled using the
no shutdown
command.
