cisco Nexus9000 one link no come up

[athan1234]

Hello to everybody.

This issue is with the interfaces nexux,. New device  new cable, and sfp all new

One side doesn't come up . I changed the negotiation to auto at the same problem; does anyone know why?

Can you share the config of port channel 

MHM

[athan1234]

Hi @MHM Cisco World 

As I watch, one of the pO11s has configured interface Eth1/47, and the other has not. Perhaps it's not necessary given that nothing is configured in this interface as of 1/47.

NEXUS 1

Eth1/47 e2 xcvrAbsen trunk auto auto --
Eth1/48 e2notconnec trunk auto auto SFP-H10GB-CU1M

NEXUS 2

Eth1/47 -- xcvrAbsen routed auto auto --
Eth1/48  connected trunk full 10G SFP-H10GB-CU1M

Maybe the issue might be resolved if I just enter the portchanel's interface 1/48.

[MHM Cisco World]

Remove vpc 11 from both PO'

The PO with vpc dont config to interconnect back to back two NSK

Note:- disable auto in both side' and shut/no shut PO after remove vpc

MHM

It's so late; I'll do  it tomorrow. Regards, @MHM Cisco World  I  will provide you with feedback tomorrow,

[athan1234]

Sorry  I had a mistake on the eschema

The idea is to do a conexion beteewn core 1 and core 2  againts 9200

The interface core 1 eth 48 -- ten1/1/4 is up

The interface core 2 eth48 --ten 1/1/3 is down ---> this is the problem

CORE 1

interface port-channel11
switchport
switchport mode trunk
speed 10000

duplex full

vpc 11

11 Po11(SU) Eth LACP Eth1/47(D) Eth1/48(P)

CORE 2

  - You may also want to compare the problem against the latest software version for your nexus 9000 model , 
     if applicable ,

  -  Have you any more recent versions to be able to test and or use ?

  M.

[athan1234]

No i havent . I am seraching some bug about my version i can not find anythhing 

[MHM Cisco World]

But I still see vpc 11 under PO?

Remove it if you connect NSK back to back

MHM

[athan1234]

Yes, however as you can see, the connection is made via nexus eth 48 in the most recent shecaema against Cisco 9200. You informedi to me t nexus— nexus  it is not necessarily. It is inexus - cisco 9200 dor this reason leve the vpc

why one of them interface is up and the other is down with the same configuration ? 

[MHM Cisco World]

can I see the config of peer-link trunk PO and config of PO of 9200/9300 

MHM

[athan1234]

Hi @MHM Cisco World  sure

This PO of 9300/9200 I need to see Po10 use between two NSK SW

Thanks
