Enabling bridging on an Ethernet interface
When an incoming packet arrives, the switch looks up the destination MAC address of the packet in the
MAC address table. If an entry is found, but the outgoing interface is the same as the receiving interface
(for example, if the destination and source MAC addresses of the packet are the same), the switch
discards the packet.
To enable the switch to return such packets to the sender through the receiving interface rather than drop
them, enable the bridging function on the Ethernet interface.

Testing the cable connection of an Ethernet interface
Optical interfaces do not support this feature.
If the link of an Ethernet interface is up, testing its cable connection will cause the link to come down and
then go up.
Test the cable connection of an Ethernet interface for a short or open circuit. The device displays cable
test results within five seconds. If any fault is detected, the test results include the length of the faulty cable
segment.
