speed (for 10/100/1000 interfaces) c e s Set the speed for 10/100/1000 Base-T Ethernet interfaces. Both sides of a link must be set to the same speed (10/100/1000) or to auto or the link may not come upSyntax speed {10 | 100 | 1000 | auto} To return to the default setting, use the no speed {10 | 100 | 1000} command. Parameters 10 100 1000 auto Enter the keyword 10 to set the interface's speed to 10 Mb/s. 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 8.3.1.0 Version 8.1.1.0 Version 7.6.1.0 Version 7.5.1.0 E-Series legacy command 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. 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 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.
