Configure port security settings
A MAC address can be defined as allowable by one of two methods: dynamically or statically.
Both methods are used 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 was not reached, then a
packet with an unknown source MAC address is learned and forwarded normally. When the
limit is reached, no more addresses are learned on the port. Any packets with source MAC
addresses that were not already learned are discarded. 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 port security settings:
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
Access the switch on-network and
connected to the Internet on page 21 or Access the switch off-network and not
connected to the Internet on page 29.
The Device UI login page displays.
If you did not yet activate your warranty, the Register to activate your warranty page
displays. For more information, see
Register the switch on page 32.
4. Enter one of the following passwords:
• Enter your device admin password.
• If you previously managed the switch through the Insight app or Cloud portal, enter
the Insight network password for the last Insight network location.
For information about the credentials, see
Credentials for the device UI on page 30.
5. Click the Go button.
