Output from the show port security mac command TABLE 22
Field Description
Port The slot and port number of the interface.
Num-Addr The number of MAC addresses secured on this interface.
Secure-Src-Addr The secure MAC address.
Resource Whether the address was secured using a local or global resource.Refer to Local and global
resources used for MAC port security on page 218 for more information.
Age-Left The number of minutes the MAC address will remain secure.
Shutdown/Time-Left Whether the interface has been shut down due to a security violation and the number of
seconds before it is enabled again.
NOTE
For FCX and ICX switches, after every switchover or failover, the MAC "Age-Left" timer is reset to start
since it is not synchronized between the master and the standby stack unit. This behavior is different on
the FSX devices where the "Age-Left" timer is not reset.
Displaying port security statistics
You can display port security statistics for an interface or for a module.
For example, to display port security statistics for interface 7/11, enter the following command.
device#show port security statistics e 7/11
Port Total-Addrs Maximum-Addrs Violation Shutdown/Time-Left
----- ----------- ------------- --------- ------------------
7/11 1 1 0 no
Syntax: show port security statistics port
Output from the show port security statisticsport command TABLE 23

Port The slot and port number of the interface.
Total-Addrs The total number of secure MAC addresses on the interface.
Maximum-Addrs The maximum number of secure MAC addresses on the interface.
Violation The number of security violations on the port.
Shutdown/Time-Left Whether the port has been shut down due to a security violation and the number of seconds
before it is enabled again.
