updated device configuration to the physical security device for those changes
to take effect. You can update multiple devices at one time. See Updating
Devices for more information.
Ethernet LANs are vulnerable to attacks such as address spoofing and Layer 2 denial of
service (DoS) on network devices. Port security features such as DHCP snooping, DAI
(dynamic ARP inspection), MAC limiting, and MAC move limiting, as well as trusted DHCP
server, help protect the access ports on your switch against the losses of information
and productivity that can result from such attacks.
To configure port security:
In the navigation tree, select Device Manager > Devices. In Device Manager, select
1.
the device for which you want to configure port security.
In the Configuration tree, expand Ethernet Switching Options.
