is compared with the MAC address of the switch. If the MAC address does not match, the
packet is forwarded to all ports that are members of the same VLAN, just like any other
broadcast packet. The packet is not forwarded to the port from which it was received.
If the source MAC address matches the MAC address of the switch, the switch can perform
one of the following actions, depending on how you configure the action:
• The port is shut down.
• A log message is generated. (If a syslog server is configured, the log message can be
sent to the syslog server.)
• The port is shut down and a log message is generated.
Loop
protection is not intended for ports that serve as uplinks between
spanning tree–aware
switches. It is intended for unmanaged switches that drop spanning tree BPDUs. Loop
protection detects physical and logical loops between Ethernet ports on a device. You must
enable loop protection globally before you can enable and configure it at the interface level.
Loop protection is supported on physical interfaces and static LAG interfaces, but not on
dynamic LAG interfaces.
Configure global Layer 2 loop protection
To configure L2 loop protection globally:
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 off-network using an Ether
net 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 18 or Access the switch off-network on page 27.
The Local Device Login page displays.
If you did not yet register the switch with your NETGEAR account, the
Register to unlock
