I have cisco Nexus 3048TP switch (48x1G + 4x10G)

Hardware cisco Nexus 3048 Chassis ("48x1GE + 4x10G Supervisor") Intel(R) Celeron(R) CPU P4505 @ 1.87GHz with 3665240 kB of memory. Processor Board ID FOC17237JKC

I am seeing this error on port e1/49 which is 10G port and i have connected 10G SFP+ transceiver 

 Ethernet1/49 is down (SFP validation failed) Dedicated Interface Hardware: 1000/10000 Ethernet, address: f872.eaae.36b8 (bia f872.eaae.36b8) MTU 1500 bytes, BW 10000000 Kbit, DLY 10 usec reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA Port mode is access auto-duplex, 10 Gb/s, media type is 10G

As per documentation they said you need to set speed so i did and got this error

n3k(config)# int e1/49 n3k(config-if)# speed 10000 ERROR: Ethernet1/49: Configuration does not match the port capability.

Interface capability 

n3k# sh int e1/49 capabilities Ethernet1/49 Model: N3K-C3048TP-1GE-SUP Type (SFP capable): Unknown Type-(unknown) Speed: 10000 Duplex: full Trunk encap. type: 802.1Q Channel: yes Broadcast suppression: percentage(0-100) Flowcontrol: rx-(off/on),tx-(off/on) Rate mode: none QOS scheduling: rx-(6q1t),tx-(1p6q0t) CoS rewrite: no ToS rewrite: no SPAN: yes UDLD: yes MDIX: no Link Debounce: yes Link Debounce Time: yes Pvlan Trunk capable: no TDR capable: no FabricPath capable: no Port mode: Routed,Switched FEX Fabric: no

This switch located in remote datacenter so i can't re-seed until i have resources available, is there anything else i can do remotely?

  • What kind of SPF is in the port? Commented Sep 11, 2018 at 20:34
  • FS fs.com/products/11552.html I have 5000 SFP running in datacenter on all kind of hardware also i have same model of switch in other datacenter and that running fine with same model of SFP, I can guarantee its not SFP+ issue.. its something related to configuration Commented Sep 11, 2018 at 20:36

  • It could certainly be a bad SFP, or you have a different hardware or software version in the switch that simply rejects this SFP.. Commented Sep 11, 2018 at 20:42
  • Believe me we have 50 nexus switches and 5 ASR routes and all running on same SFP+ and they all fine.. even my other datacenter has Nexus 3048 switch running on same model of SFP.. do you still this it's SFP issue? I have working switch on same model Commented Sep 11, 2018 at 20:43

Solved:

After reboot switch it fixed my issue, Now its showing SFP Type 10Gbase-SR

n3k# show int e1/49 capabilities Ethernet1/49 Model: N3K-C3048TP-1GE-SUP Type (SFP capable): 10Gbase-SR Speed: 10000 Duplex: full Trunk encap. type: 802.1Q Channel: yes

Look like you need to set speed first before inserting SFP.
