Displaying port security settings
Syntax:
show port-security
show port-security <port-number>
show port-security [<port-number>-<port-number>]...[,<port-number>]
The CLI uses the same command to provide two types of port security listings:
-
All ports on the switch with their Learn Mode and (alarm) Action
-
Only the specified ports with their Learn Mode, Address Limit, (alarm) Action, and Authorized Addresses
Without port parameters,
show port-security displays Operating Control settings for all ports on a switch.
Port security listing (ports 7 and 8 show the default setting)
switch(config)# show port-security Port Security Port Learn Mode | Action Eavesdrop Prevention ---- ----------- + ------------------------ -------------------- 1 Continuous | Send Alarm, Disable Port Enabled 2 Continuous | Send Alarm, Disable Port Enabled 3 Static | Send Alarm Enabled 4 Continuous | Send Alarm, Disable Port Enabled 5 Continuous | Send Alarm, Disable Port Enabled 6 Continuous | Send Alarm, Disable Port Enabled 7 Continuous | None Enabled 8 Continuous | None Enabled
With port numbers included in the command,
show port-security displays Learn Mode, Address Limit, (alarm) Action, and Authorized Addresses for the specified ports on a switch. The following example lists the full port security configuration for a single port:
The port security configuration display for a single port
switch(config)# show port-security 3 Port Security Port : 3 Learn Mode [Continuous] : Static Address Limit [1] : 1 Action [None] : None Eavesdrop Prevention [Enabled] : Enabled Authorized Addresses -------------------- 00906d-fdcc00
The next example shows the option for entering a range of ports, including a series of non-contiguous ports. Note that no spaces are allowed in the port number portion of the command string:
