Concept Guide

• Auto Negotiation — Displays whether auto-negotiation is Enabled or Disabled on the interface.
Autonegotiation allows two devices at either end of a 10 Mbps, 100 Mbps, or 1000 Mbps link to
advertise and negotiate the link operational mode — such as the speed of the link and the duplex
configuration of half or full duplex — to the highest common denominator.
• Speed — Displays the speed of the port.
• MTU — Displays the Maximum Transmission Unit (MTU) (frame size) for an Ethernet interface.
This setting is the limit for the largest packet that can be passed through the interface.
• Remote Fault Signaling — (If applicable) Displays whether the remote fault signaling feature is
Enabled or Disabled. This feature brings the interface up or down when a Remote Fault
Indication (RFI) error is detected.
• Auto LAG — (If applicable) Displays whether the Auto LAG feature is Enabled or Disabled. This
feature has the device automatically assign internal ports to Link Aggregation Groups.
• Keep Alive — Displays whether the keep alive feature is Enabled, Disabled, or blank (not
applicable). This feature periodically transmits keepalive packets to keep an interface alive when
not transmitting data.
You can also filter this list from the Filter By menu and select All Ports, Internal Ports, or External
Ports.

Configuring Port Settings
From the Port Settings section of the Port Configuration page, you can configure port settings on the
I/O Aggregator device.
NOTE: You can only configure these settings for M1000e and FN IOA devices in standalone or VLT
mode.
Tip: You can click View Port Configurations to view all currently configured port settings.
1. From the navigation menu, click Port Configuration.
The Port Configuration page appears.
2. From the Interface drop-down menu, you can select one of the following filters:
• All Ports
• Internal Ports
• External Ports
• Custom Range
• Individual port number
3. If you select Custom Range in step 2, in the Port Range field, enter the ports in the range. Separate
individual ports with a comma. You can use a dash to denote a range. For example: 1,2,6–8.
The Interface(s) Selected field displays the selected interface types with chassis slot and port number
4. In the Interface Description field, enter a description of the interface. The maximum description
length is 240 alphanumeric characters.
5. In the Administrative State field, select Enabled or Disabled. If enabled, the port can link to another
port.
6. In the Auto Negotiation field, select Enabled or Disabled. Autonegotiation allows two devices at
either end of a 10 Mbps, 100 Mbps, or 1000 Mbps link to advertise and negotiate the link operational
mode — such as the speed of the link and the duplex configuration of half or full duplex — to the
highest common denominator. If you select
Enabled, skip to step 8.
