Before you begin
During bulk port operations, change the 
Pagination to cover more ports
			on the page as only the ports listed on the current page are updated.
About this task
XCO 3.5.0 and later releases support multiple or bulk port edits.
		Procedure
- 
				In the Navigation menu, select
						Device
						Inventory.
			
- 
				In the Devices page, click anywhere in the
                                        required device row except the Actions column ( )
                                        to proceed to the device Overview page. )
                                        to proceed to the device Overview page.
- 
				In the Device Config menu,
					select . 
				The list of ports is
					displayed. 
- 
				Select the check boxes for the
					ports you want to edit.
			
- 
				Select Edit from the
					ports table menu ( ). ).
- 
				Take the following steps to edit
					the selected ports configuration.
				
					- 
						(SLX and 9920 only) In the Forward Error
								Correction (FEC) 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. 
- (9920
									only) Though you can select an FEC value for 400G during bulk
									port edit, it fails eventually as FEC value change is not
									supported for 400G.
 
 
							 Note    FEC can be updated only when the port is in shutdown state. 
 
- 
						(9920 only) To enable communication
							between two Ethernet devices, select Link Fault
								Signaling (LFS).
						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 admin status to Up.
						When you select this
							field, you initiate the no shutdown
							command on the device, which changes the admin status to Up. When the
							field is not selected, the shutdown
							command runs on the port and the admin status changes to Down. 
 
- 
				Select Save.
				A notification is displayed to
					show the status of the edited ports.
