Trunk between Cisco 3850 and HP8212zl

[mnour401917_2]

Hi All,

I'm setting a Trunk between Cisco 3850 switches and HP for a customer, I have a problem with 10GB interfaces (Cisco and HP) where the speed Auto negotiation only achieves 1GB, any idea what i need to do to achieve 10GB? Also hard coding the interfaces doesn't seem to help.

Thanks

Nour

Hello

he trunk is up/up state correct but just only works at 1GB ( hardcoded or negociated)

Can you show the capabilites of either port please:

Cisco

HP
Sh interface Brief or Ehternet  ( no sure)
