Hi Breland, Uplink fast makes use of root ports (or alternate root ports) and listens for BPDUs originated from the Root bridge in order to determine if the primary uplink has failed and it should switch to the alternate port.
The root bridge only has designated ports and originates the BPDUs. Also, uplink fast purposesly increases the bridge priority on purpose so it significantly reduces the chance of the bridge becoming root because the feature doesn't make sense to have active on a root bridge. Perhaps this link can help further http://www.cisco.com/en/US/tech/tk389/tk621/technologies_tech_note09186a0080094641.shtml#uplink_fast_theory Cheers, Adam On Thu, Jan 5, 2012 at 11:50 AM, Breland Rogers <[email protected]>wrote: > Hello, > > > Would anyone know as to why were not able or not suppose to use the Uplink > feature on the root bride? > > Thanks > _______________________________________________ > For more information regarding industry leading CCIE Lab training, please > visit www.ipexpert.com > > Are you a CCNP or CCIE and looking for a job?
