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

Nexux 1

interface Ethernet1/48

Can you share the config of port channel 

MHM

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.

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,

Sorry  I had a mistake on the eschema

athan1234_3-1723539151594.png

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)

Eth1/48 connected trunk full 10G SFP-H10GB-CU1M

 

CORE 2


interface port-channel11
switchport
switchport mode trunk
speed 10000
duplex full
vpc 11

11 Po11(SD) Eth LACP Eth1/47(D) Eth1/48(D)

Eth1/48 e2 notconnec trunk full 10G SFP-H10GB-CU1M

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

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

But I still see vpc 11 under PO?

Remove it if you connect NSK back to back

MHM

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 ? 

 

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

MHM

Hi @MHM Cisco World  sure

interface Port-channel1
switchport trunk allowed vlan 2163,2255,3000
switchport mode trunk
speed nonegotiate
duplex full
end

endshow run interface Te1/1/4

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

Thanks
