I have a cisco 4510R+E switch. I know how to configure uplinks on other switches via the hw-module commands. I am not seeing any options under hw-module to configure from 10gig to 1gig. Hoping someone might know how to convert the uplinks on this switch from 10 gig to 1 gig? The IOS version is 03.05.00.E 15.0(1r)SG5.

    What SUP do you have installed? dual or single as well? – knotseh Jun 3 '14 at 22:47
  • Sure its the 7E and there is only one installed. – Dave K Jun 8 '14 at 20:17

Found that the newer switches actually auto negotiate based on the GBIC rather than having to manually convert the 10gig interface to gig as the older switches did.

  • The GBIG/SFP/SFP+ almost always dictate the speed you're using (some supports more than one speed, but I haven't seen lots of them - always check the specs!) Also always check if your device supports the GBIC/SFP you're using (I've had bad experience with some devices not supporting 100mb sfps, not great when the other end doesn't support gig... :/ ) – Remi Letourneau Jun 6 '14 at 19:00
  • if you could please add the sup module that you have installed and whether its dual or single sup - that would be appreciated. Especially for others who come with similar questions! thx – knotseh Jun 7 '14 at 7:16
