    Hi!

    I am just trying to disable STP on some (edge-)ports of my Arista 7050s, but I do not find a solution to disable STP on a port.

    I only found the possibility to define as "portfast", but there is not much documentation on what the commands REALLY do:

    spanning tree portfast
    --> STP is on, but with VERY short block time?
    spanning-tree portfast edge
    --> STP is off?
    spanning-tree portfast normal
    --> STP is off, but will be on, if BPDU is received?
    spanning-tree portfast network
    --> NO idea...

    Can you help me?

    Thank you for your help!!

    Hi
    we have disabled spanning tree on a port in such a way:

    interface Ethernet34
    description peering
    switchport trunk native vlan 13
    switchport trunk allowed vlan 13,791
    switchport mode trunk
    spanning-tree bpduguard disable
    spanning-tree bpdufilter enable
    !
