Use this procedure to provision Ethernet interfaces. This task helps you complete the required configuration, verification, or management action in Cisco Optical Site Manager.

Provision Ethernet interfaces by configuring Ethernet port parameters on a network card or device, ensuring proper operation and network integration.

Set operational parameters such as speed, duplex mode, MTU size, Forward Error Correction (FEC), Auto-Negotiation, and service state.

Before you begin

Follow these steps to provision the parameters for the Ethernet interfaces of a card.

Procedure

Click the Provisioning tab.
Click the Ethernet Interfaces section to expand it.
Click the Edit button.
Modify any of the Ethernet settings as described in the Table 1 table.

The available parameters depend on the card mode.
Click Apply.

The system saves your changes, and the modified ethernet interface settings are displayed for the selected card.

Table 1. Ethernet Settings
Parameter	Description	Options
Port	(Display only) Displays the port number	—
Description	Description of the port.	—
Speed	Sets the expected port speed.	—
MTU	Sets the maximum size of the Ethernet frames that are accepted by the port. The port must be in OOS or locked state.	Numeric. Default value: 1548 Valid range: 64 – 9700
FEC	Sets the FEC mode. When set to On, FEC is enabled.	NA Auto (default) On Off
Duplex	Sets the expected duplex capability of ports.	Full Half
