We will soon have a lab setup that has two core routers that have GigE
LX(long haul) interfaces. We need to test connectivity between the two
routers with a switch in between. The problem is the switch we have has GigE
SX(not LX) interfaces. The physical cable distance will be very short(under
400m). My question: will the switch have to have the LX interfaces in order
for this to work even at relatively short distances? or will the SX
interfaces work as well. I'm not sure what the difference is between SX and
LX is at the physical layer. TIA,
Scott
