Enabling Bridging On An Ethernet Interface; Testing The Cable On An Ethernet Interface - H3C S5810 Series Operation Manual

When crossover cables are used, the local MDI mode must be the same as the remote MDI mode,
or the MDI mode of at least one end must be set to auto.
Follow these steps to configure the MDI mode for an Ethernet interface:
To do...
Enter system view
Enter Ethernet interface view
Configure the MDI mode for the
Ethernet interface

Enabling Bridging on an Ethernet Interface

After an Ethernet port receives a data packet, it looks up the MAC address table of the device for an
entry that contains the destination MAC address of the packet. If such an entry exists but the egress
interface in the entry is the receiving interface itself, the device discards this packet. However, if bridging
is enabled on the receiving interface, the device does not discard the packet. Instead, it sends the
packet out the receiving interface.
Follow these steps to enable bridging on an Ethernet interface:
To do...
Enter system view
Enter Ethernet interface view
Enable bridging on the Ethernet
interface

Testing the Cable on an Ethernet Interface

T10-Gigabit Ethernet ports and combo ports operating as optical interfaces do not support this function.
Follow these steps to test the current operating state of the cable connected to an Ethernet interface:
To do...
Enter system view
Enter Ethernet interface view
Use the command...
system-view
interface interface-type
interface-number
mdi { across | auto | normal }
Use the command...
system-view
interface interface-type
interface-number
port bridge enable
Use the command...

Optional
Defaults to auto. That is, the
Ethernet interface determines
the physical pin roles (transmit
or receive) through negotiation.
