The software allows the use of transceivers and direct attach cables from any vendor, which means that the switch will bring up the port operationally when using any transceiver. Extreme Networks does not provide support for operational issues related to the use of non-Extreme Networks branded transceivers and direct attached cables used in the switches.
To find product descriptions and compatibility information for optical transceivers and components, visit the Extreme Optics website.
Use auto-negotiation to enable the device to automatically negotiate the best common data rate and duplex mode to use between two auto-negotiation-capable Ethernet devices.
When you use a 1 Gb SFP transceiver on a 10 Gb SFP+ port, ensure that auto-negotiation is enabled.
For 1000BASE-T SFP transceivers, the best practice is to perform custom auto-negotiation at the remote native copper port. This can prevent connections from failing if the speed or duplex negotiation changes.
Forward Error Correction (FEC) is a method of obtaining error control in data transmission over an unreliable or noisy channel in which the source (transmitter) encodes the data in a redundant way by using an error correcting code (ECC). This redundancy enables a destination (receiver) to detect a limited number of errors and correct them without requiring a re-transmission.
For more information about FEC, see VOSS User Guide.
