auto | optic }no speed-duplexBy default, the speed is auto-negotiated. For 08.0.95C and above, speed optic is the default configuration.
Interface configuration mode
The Gigabit Ethernet copper ports are designed to auto-sense and auto-negotiate the speed and duplex mode of the connected device. If the attached device does not support this operation, you can manually enter the port speed to operate at either 10, 100, or 1000 Mbps. The default and recommended setting is 10/100/1000 auto-sense.
On FastIron devices, when setting the speed and duplex-mode of an interface to 1000-full, configure one side of the link as master (1000-full-master ) and the other side as slave (1000-full-slave ).
Both ends of the link must be configured to operate at the same speed.
2500 and the 5G speeds are applicable only to Multi-Gigabit ports.
The
no form of the command restores the default.
For the Ruckus ICX 7850-48F, SFP28 ports are grouped into fours. For example, ports 1/1/1 to 1/1/4 are one group and ports 1/1/5 to 1/1/8 are another group, and so on. All ports in a four-port group must be configured to the same value. This restriction does not apply if configuring values between 1G and 10G.
When the speed-duplex optic command is used, ICX switches can automatically set the port speeds based on the type of optics present. For example, when 1G optics are installed on a 10G SFP+ port that is capable of running at 1G, the speed should be automatically set to 1G. If a 10G optic is installed, the port should revert back to its default of 10G. For Copper GBICs, auto-negotiation is applied as applicable. This is applicable for 10G fiber ports, and speed optic is the default configuration for 8095C and above.
Refer RUCKUS FastIron Management Configuration Guide for more information.
The following example changes the port speed of copper interface 1/1/8 on a device from the default of 10/100/1000 auto-sense, to 100 Mbps operating in full-duplex mode.
device(config)# interface ethernet 1/1/8 device(config-if-e1000-1/1/8)# speed-duplex 100-full
The following example changes the port speed of a four port group to 10 Mbps operating in full-duplex mode for an ICX 7850-48F device.
ICX-7850# configure terminal ICX-7850(config)# interface ethernet 1/1/45 to 1/1/48 ICX-7850(config-if-e1000-1/1/8)# speed-duplex 10g-full
The following example sets the speed based on optic type where the speed has been automatically set to 1G.
