Recentdays I Can see this duplex error in my switch and router.
"Duplex mismatch discovered on Gig0/1 ( Not Halfduplex) with Switch1 Gi1/0/1(Half duplex)"
but I checked in both ends. Both ends are set it as "Full Duplex". if i set as "Half duplex" is that will lead of down time. Pls suggest to aviod the mismatch.
