Trunking in FSW

Just realized that the term Trunk is not the same in FSW as in Cisco. Thats why I am trying to clarify trunking between cisco and FWS.

I have a:

  • FWS
    • with just one VLAN (VLAN 10)
    • on Port3 is a computer connected:
      • native & allowed vlan 10
    • Trunk:
      • no Ling Aggression.
      • just want to use the nr port 24 to forward traffic from vlan 10 to a cisco port which is in access mode vlan 10.
  • cisco swich
    • with VLAN 9 & 11
    • on port 15 is a laptop connected:
      • mode access vlan 10
    • Trunk on port 25
      • mode trunk
      • native vlan 9
      • allowed vlan 1, 10 & 11

So my question is:

  • I know that, while trunking both switches's ports should have the same vlan as native vlan.
  • Since my cisco switch has vlan 9 as native, i configured the FSW like this:
    • edit port24
    • set native-vlan 9
    • set allowed-vlan 10
    • set stp-state enabled

I see that my traffic goes through and i can ping the laptop on my cisco switch. Am i doing it correctly ?

Your descriptions are mismatching. If the diagram is correct, the config for port24 on the FSW should be:
config switch interface

  edit port24

    set native-vlan 9

    set allowed-vlan 10

  next

end

 

STP/MSTP is enabled by default at all ports.

And for the device port:
edit port3

  set native-vlan 10

next

 

You don't need to configure allowed-vlan for the native-vlan. Then this is practically the same as Cisco's "access" port with "switchport access vlan 10".
