Insight Managed 28-Port Gigabit Ethernet Smart Cloud Switch with 2 SFP 1G & 2 SFP+ 10G Fiber Ports
forwarded to all ports that are members of the same VLAN, just like any other multicast
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.
If loop protection is disabled, the multicast packet is silently dropped.
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 global Layer 2 loop protection:
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 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
The login window opens.
4.
Enter the switch’s password in the
password
field.
The default password is
password
. If you added the switch to a network on the Insight
app before and you did not yet change the password through the local browser interface,
enter your Insight network password.
The System Information page displays.
