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:
Entering a range of ports
switch(config)# show port-security 1-3,6,8
