2960X Switch will only uplink with 1 port on QNAP NAS.

ello,

 

I have a 2960X-48FPS-L with 15.2-7.E5 (also tested on 15.0), and when I plug in the first port from a QNAP NAS it will not recognize it being plugged in, but it will recognize the second port.  With Term Mon turned on, it shows no log of it being plugged in. 

 

I plug the same NAS into a 2960S switch and it will recognize both ports.  I have also tried a different 2960X with the same result of Port 1 on the NAS not going UP.

 

Another side note on these 2960X's, when I try to plug in our building security system in to ports 1-24 it will not recognize the device, but if I plug it into ports 25-48, it works.

 

Below is my port config:

interface GigabitEthernet2/0/5
description To QNAP
switchport access vlan 31
switchport mode access
switchport voice vlan 100
priority-queue out
mls qos trust device cisco-phone
spanning-tree portfast edge
spanning-tree bpdufilter disable
spanning-tree bpduguard disable

 

Thanks in advance for any advice!

Jason

QNAP Port 1 ------> DLink (Dummy Switch) -------> Cisco 2960X Int Gi1/0/5

May this prove the QNAP side issue - some handshake with a new switch somehow.

But it works with a 2960S?
