1. Port Hardware Limitations Most 10G SFP+ ports are designed to operate at 10 Gbps and do not support manual speed reduction to 1 Gbps unless the port or PIC explicitly supports dual-rate operation. Attempting to configure the port speed via CLI often fails because the underlying hardware does not allow a lower speed setting . 2. Using Compatible SFP Transceivers The standard method to achieve 1G operation on a 10G port is to replace the 10G SFP+ module with a 1G SFP module (e.g., SFP-1GE-SX or SFP-1GE-LX). The switch will then automatically configure the port to operate at 1 Gbps . This is the only reliable approach on most Juniper QFX and Cisco 10G switches. 3. Auto-Negotiation and Configuration
link-speed 1g only work on aggregated interfaces or when using compatible 1G optics .show interfaces or equivalent CLI command.Directly forcing a 10G SFP+ port to 1G via software is generally not possible. The recommended and supported method is to use a 1G SFP transceiver, which allows the port to operate at 1 Gbps while maintaining compatibility with the connected device . Attempting to override the speed in software without changing the optics is typically unsupported and may leave the port in an unconnected state.
