The shut and no shut configuration commands may not use the SFP transceiver’s TX Disable control register software. Instead, the TX Disable hardware low-speed pin signal will always be used. This does not result in operational or behavioral differences for Arista Networks transceivers. The configuration commands transceiver frequency and transceiver channel are not supported on the first eight ports (ports 1-8).
