I just tried to establish a fiber (MM) connection between a c2960x and a c2960x using SFP-10GBase-SR modules on both sides, but link is not coming up
Both side link not come up and while check getting
TenGigabitEthernet1/0/1 is down, line protocol is down (notconnect)
All on the same ports and modules and also different ports an modules per switch.
Any suggestions on why a connection between the c2960x and the c2960X doesn't work?
