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:
Enter configuration commands, one per line. End with CNTL/Z.
The duplex command does not show up until the port's media type is set.
