duplex (10/100 Interfaces) c e s Configure duplex mode on any physical interfaces where the speed is set to 10/100.Syntax duplex {half | full} To return to the default setting, enter no duplex. Parameters half Enter the keyword half to set the physical interface to transmit only in one direction. full Enter the keyword full to set the physical interface to transmit in both directions. Defaults Not configured Command Modes INTERFACE Command History Version 8.3.5.0 Version 8.1.1.0 Version 7.6.1.0 Version 7.5.1.0 Version 6.4.1.0 Introduced on the S55. Introduced on E-Series ExaScale Introduced on S-Series Introduced on C-Series Introduced Usage Information This command applies to any physical interface with speed set to 10/100. 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. Related Commands speed (for 10/100/1000 interfaces) negotiation auto Set the speed on the Base-T Ethernet interface. Enable or disable auto-negotiation on an interface. flowcontrol c e s Control how the system responds to and generates 802.3x pause frames on 1Gig and 10Gig line cards. Syntax flowcontrol rx {off | on} tx {off | on} threshold { } The threshold keyword is supported on C-Series and S-Series only. To return to the default, use the no flowcontrol rx {off | on} tx {off | on} threshold command. Parameters rx on rx off tx on Enter the keywords rx on to process the received flow control frames on this port. This is the default value for the receive side. Enter the keywords rx off to ignore the received flow control frames on this port. Enter the keywords tx on to send control frames from this port to the connected device when a higher rate of traffic is received. This is the default value on the send side. Interfaces | 451
