cisco switches uplink issue
hi
i have problem connecting two cisco catalyst switch UPLINK
1- Cisco catalyst 2960 >> interface gigaethernet 0/1
2- Cisco 3750 fiber only >> interface gigaethernet1/0/5
========================== ========== ========== ========== =======
The problem is after some configuration i have made the led from the 2960 is blinking and from the 3750 core switch no blinking at all !!

if you notice that the status from the 3750 side is notconnect !!
any idea how to fix that issue

Is the cable ok? And didn't you switch the connectors?
ASKER
cable is new
you know what !! i found that the connector is SM and am using MM cable
could be this is the reason ?

ASKER
u correct man
i swapped then found both of them notconnect status
thats mean one of the connectors are not working
am i correct ?
