Full-duplex, 100Mb/s, 100BaseTX/FX -----Original Message----- From: Jon D [mailto:[EMAIL PROTECTED] Sent: 20 February 2008 14:42 To: NT System Admin Issues Subject: Determining duplex of cisco router interface? I've got a router that is running at 10mb half duplex. I'm planning on trying to force it to full duplex, but I'm wondering if there's a way to tell what duplex it is before I try to force it to full? I would ASSUME that no card sold in the last 10 years would be only half duplex?
