Note: This i speed is not supported on the LC-EH-GE-50P or the LC-EJ-GE-50P card. If the command is entered for these interfaces, an error message appears. Enter the keyword 100 to set the interface's speed to 10/100 Mb/s. Note: When this setting is enabled, only 100Base-FX optics are supported on the LC-EH-GE-50P or the LC-EJ-GE-50P card. Enter the keyword 1000 to set the interface's speed to 1000 Mb/s. (Auto-negotiation is enabled. See negotiation auto for more information) Note: When this setting is enabled, only 100oBase-FX optics are supported on the LC-EH-GE-50P or the LC-EJ-GE-50P card. Enter the keyword auto to set the interface to auto-negotiate its speed. (Auto-negotiation is enabled. See negotiation auto for more information) Defaults auto Command Modes INTERFACE Command History Version 8.3.5.0 Version 8.3.1.0 Version 8.1.1.0 Version 7.6.1.0 Version 7.5.1.0 E-Series legacy command Introduced on the S55. Supported on LC-EH-GE-50P or the LC-EJ-GE-50P cards. Introduced on E-Series ExaScale Introduced on S-Series Introduced on C-Series Usage Information This command is found on the 10/100/1000 Base-T Ethernet interfaces. With speed 1000 configured on a copper interface, the speed is not auto-negotiated. The interface will operate only at 1000 Mbps. With speed 100 configured on a copper interface, the speed is auto-negotiated. The interface will operate at 10 Mbps or at 100 Mbps. When auto is enabled, the system performs and automatic discovery to determine the optics installed and configure the appropriate speed. When you configure a speed for the 10/100/1000 interface, you should confirm the negotiation auto command setting. Both sides of the link should have auto-negotiation either enabled or disabled. For speed settings of 1000 or auto, the software sets the link to auto-negotiation, and you cannot change that setting. Note: Starting with FTOS 7.8.1.0, when a copper SFP2 module with catalog number GP-SFP2-1T is used in the S25P model of the S-Series, its speed can be manually set with the speed command. When the speed is set to 10 or 100 Mbps, the duplex command can also be executed.
