You can change several port properties,
including description, port speed, MTU, Forward Error Correction, and Link Fault
Signaling.
Procedure
-
In the Navigation menu, select
Configure.
-
In the Devices panel, select the
device for which you want to configure a port.
-
In the Device Config menu,
expand Ports.
-
Select a port to display a list of properties.
-
In the Description field, provide new information.
-
In the Port Speed field, select
-
In the MTU field, select the maximum transmission unit
for packets that pass through the port.
-
In the Breakout field, select one of the
following:
- 4x10G:
Configures four 10G breakout interfaces on the port.
- 4x25G:
Configures four 25G breakout interfaces on a port.
- None
-
In the Forward Error Correction field, select one of the
following:
- Auto-negotiation: Selects the appropriate
algorithm automatically.
- FC-FEC: An
algorithm that corrects errors in a block of data, with lower latency than
RS-FEC.
- RS-FEC: An algorithm that corrects errors in a
block of data, with better error correction than FC-FEC.
- Disabled: Disables the FEC feature.
FEC corrects errors in data without the need for retransmission of the data.
Port speed determines which FEC configuration is supported.
- For 100G ports, RS-FEC, Auto-negotiation, and Disabled are
supported.
- For 25G ports, RS-FEC, FC-FEC, Auto-negotiation, and Disabled are
supported.
- For 40G and 10G ports, only Disabled is supported.
-
To enable communication between two Ethernet devices, select Link
Fault Signaling.
Link Fault Signaling is a physical layer
protocol that enables a port to report fault conditions on inbound and outbound
ports.
-
Select Enable to change
the port operating status to Up.
When you select this field, you
initiate the no
shutdown command on the device, which changes the operating status
to Up. When the field is not selected, the shutdown command
runs on the port and the operating status changes to Down.
-
Save (✔) your
selections.
