Loopbacks
The EtherNID supports in-service loopbacks on either the client or network ports. To view a
list of all loopbacks and their settings, open the
OAM > Loopback
page.
The following information is presented for each loopback:
•
Name:
This field reports the loopback instance name, as configured in the loopback
configuration page. Click on an instance name to configure it.
•
Lpbk state:
Reports the enable/disable state of the loopback. An enabled loopback may
not necessarily loopback traffic; this depends on the location setting. An instance enabled
to react on external loopback commands is not shown in this field.
•
Lpbk mode:
The loopback control logic, once enabled, may be using the standard IEEE
802.3ah mode or may be using a private or proprietary mode. When using the private
mode, the user can select filters and can allow other traffic to flow through, effectively
doing an in-service loopback.
•
Location:
A loopback instance may be local or remote. Once enabled, a local loopback
immediately applies the loopback to the unit as programmed. An enabled remote
loopback will instruct the unit to transmit a loopback request to its OAM partner.
•
Filter type:
For private loopback mode, a filter must be selected. See the loopback
configuration page for details.
