BPDU conflict between Cisco meraki and Dell Switch force10

[NABILOU]

Hi Guys,

I have BPDU Conflict between Dell Switch (force10) and cisco meraki ms210, as you can see in the pecture attached

I have configued the lacp port and stp. is anyone had the same issue ? could help me please ?

Thank you

What version of STP are the F10's running? Are all ports configured as trunks? Are native VLANs consistent?

Edit: Oh, some of that is in there.. Just upside down. Can you fix the picture?

Fixed the image

Can you provide how you have Te0/24 on the DELL switches configured, as well as how you have the x/28 ports configured on the Meraki switches

Did you use the vlt-peer-lag port-channel command on the Dells?

This setup guide for Dell looks good.  Ignore the VMWare side, and the MTU change.

Hi, 

Yes, I have configured trunk and vlan natative ...... on both

the VLT port lag has added already. here is the configuration on 2 dell switchs : 

# interface Port-channel 100
 no ip address
 portmode hybrid
 switchport
 channel-member TenGigabitEthernet 0/24
 vlt-peer-lag port-channel 100
 no shutdown 

I have tried with dynamique LACP, static LACP. unfortunately I have same erreur
