We have a WS-C3560-8PC. we have a 100 mb Gbic in G0/1. these 100mb GBICS default to half duplex when inserted. on the 24 and 48 port 3560 I can just go into the CLI and force the port to full duplex. for some reason that is not an option on this 8 port switch. Auto is the only option. Is this an IOS or architecture issue?

The gig0/1 port can be

hardcoded to full duplex if you issue the following commands:


Switch#config t

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)#int gig0/1

Switch(config-if)#media-type sfp

Switch(config-if)#duplex full

Switch(config-if)#end


The duplex command does not show up until the port's media type is set.

Architecture design when using fiber. When using Auto/Auto - do you negotiate to 100/FD?
