i have checked module, cable. Everything is ok but interface status still "Link not connected"

Here is port-config of 9516

Hi
whats the SFP your using on both sides ?
have you tried crossing the fibre at one end incase there mismatched tx/rx
the port-channels are admin up yes

[PhuongHTz]

Hi,

i am using Cisco SFP module for both side

Ethernet2/32
transceiver is present
type is 10Gbase-SR-S
name is CISCO-AVAGO
part number is SFBR-709SMZ-CS2

yesterday, i tried crossing the fibre at one end but nothing change and port-channel are admin up.

Po236        10      eth  trunk  down    No operational members      auto(D)  la

thanks

this configuration is the same with me but port still down.

thanks!

are you sure the fibre cable is good and the sfps are confirmed working you've tested them on an already working connection to be sure ?
Something at layer 1 is wrong , dodgy sfp , dodgy cable
is there just 1 nexus here or 2 in vpc and is it direct to the 2960 or any patch panels in between ?

that sfp type should be fine im running them too

Ethernet1/7
transceiver is present
type is 10Gbase-SR
name is CISCO-AVAGO
part number is SFBR-709SMZ-CS1
revision is G4.1

[PhuongHTz]

Yes, i am sure.

I have checked cable, SPF module for another port and another 2960x switch.

I have 2 nexus using vPC and it is connect directly to 2960x switch.

Anyway i think OS which i am using have problem :)
