Is it possible to completely disable spanning-tree on a trunk port. I have a situation were a Sun server will be connected to a trunk port and will be tagging packets with various vlan ids. I have been told that the port must have spanning-tree disabled (yes I know its madness).
I had previously thought that it was only possible to turn vlan off on a vlan by vlan basis on a switch.
Is it possible to turn spanning-tree off on an individual port basis.
You can effectively turn off STP for a port by using the "spanning-tree bpdufilter enable" command under the interface -
Do you know why you have to disable it. If it is an issue with the NIC taking 45 seconds to begin forwarding you could look to use "spanning-tree portfast trunk" which allows the trunk port to begin forwarding immmediately but still runs STP - it's like normal portfast but for trunk links. It should never really be used on switch to switch links but it is fine for servers with trunk links.
