I'm having some trouble with a nexus 3k and vlan configuration. This is the first cisco device I've touched in many years and normally use Arista and Ubiquiti switches.
This seems like it should be pretty simple, there are a few hypervisors and storage boxes with lacp 40gbit redundant interfaces.
All ports on the switch are switchport mode trunk, switchport trunk allowed vlan all and vlans 1-255 are defined.
Trunk port 1/64 is qsfp to Arista trunk port configured the same way, same vlans defined, allowed, etc.
I have two problems
I can't get traffic going out from a server into the switch to leave the switch untagged/native, I do see inbound untagged traffic getting to my test server trunk interface.
I tried to resolve this by removing vlan native from our entire network putting that traffic into vlan 10, this works great everywhere I tested (Arista and other non cisco switches)
The other issue I have is I can't get traffic from some vlans, such as 10 to work from the test server, some do work like server management vlans over the trunk lacp interface.
When moving the server from the 40g cisco port to a 40g arista port it all works perfect, and traffic on the local cisco switch seems to work.
What have I missed about the vlan setup on these cisco switches when working with other switches?
