Thanks for your reply,
May be I missing something but do you refers to the speed of the interface? The link is UP and I believe that it's bandwidth is 1 Gbps (I forced speed of the switch to 1Gbps) Regarding the command speed of the router only give the options of 10, 100 and auto. This is for the Gigabit copper ports. If I use the same speed command for the Gigabit optical interfaces (without SFP) it appears 10,100,1000 and auto. Does it mean that the cooper interfaces (Gigabit 0/2/[28-31]) can only work to 100 Mbps even the link is up to 1Gbps). I couldn't test optical interfaces as I don't have SFPs.
Thanks in advance
