Testing The Cable Connection Of An Ethernet Interface; Enabling Bridging On An Ethernet Interface; Displaying And Maintaining An Ethernet Interface - HP FlexFabric 12900 Series Configuration Manual

Testing the cable connection of an Ethernet interface

IMPORTANT:
Fiber ports do not support this feature.
This feature tests the cable connection of an Ethernet interface and displays cable test results within 5
seconds. The test results include the cable's status and some physical parameters. If any fault is detected,
the test results include the length of the faulty cable segment.
To test the cable connection of an Ethernet interface:
Step
1. Enter system view.
2. Enter Ethernet
interface view.
3. Test the cable
connected to the
Ethernet interface.

Enabling bridging on an Ethernet interface

When a packet arrives at an interface, the switch looks up the destination MAC address of the packet
in the MAC address table. If an entry is found and the outgoing interface is the same as the incoming
interface, the switch drops the packet.
To enable the switch to forward such packets rather than drop them, enable the bridging function on the
Ethernet interface.
To enable bridging on an Ethernet interface:
Step
1. Enter system view.
2. Enter Ethernet interface
view.
3. Enable bridging on the
Ethernet interface.

Displaying and maintaining an Ethernet interface

Execute display commands in any view and reset commands in user view.
Task

If the link of an Ethernet port is up,
testing its cable connection will cause
the link to go down and then come
up.
