Port speed and duplex mode configuration

The following example sets the port speed of copper interface 8 on a FastIron device 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
Note: On all ICX 7xxx devices, speed-duplex 1000-full must be configured on both of the SFP sides for the front 4x10G module to link-up the port as 1G speed.

Please confirm new example
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
Note: 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.
