The following table describes the fields in the Port Security Violations table.
Table 53. Port Security Violations information
Field Description
Port The physical interface.
Last Violation MAC The source MAC address of the last packet that was discarded at a locked port.
VLAN ID The VLAN ID corresponding to the last MAC address violation.
Configure a Port Security Interface
A MAC address can be defined as allowed on a port by one of two methods: dynamically or
statically. Both methods can be concurrently when a port is locked.
Dynamic locking implements a first arrival mechanism for port security. You specify how
many addresses can be learned on the locked port. If the limit is not reached, a packet with
an unknown source MAC address is learned and forwarded normally. If the limit is reached,
no more addresses are learned on the port. Any packets with source MAC addresses that
were not already learned are dropped. You can effectively disable dynamic locking by setting
the number of allowable dynamic entries to zero.
Static locking allows you to specify a list of MAC addresses that are allowed on a port. The
behavior of packets is the same as for dynamic locking: only packets with an allowable
source MAC address can be forwarded.
 To configure a port security interface:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is of
f-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser
, enter the IP address of the switch.
If you do not know the IP address of the switch, see Change the Default IP Address of the
Switch on page 11.
Your web browser might display a security message, which you can ignore. For more
information, see Access the Local Browser Interface on page 19.
The login window opens.
4. Enter the switch’
s password in the Password field.
The default password is password.
The System Information page displays.
5. Select Security > T
raffic Control > Port Security > Interface Configuration.
