spanning tree portfast for cisco to palo links

M.Allen — Thu, 21 Aug 2025 11:11:07 GMT

I am moving some palo interfaces to a new cisco switch.

What is the recommended spanning tree configuration on both palo and cisco sides when connecting these devices?

PA(config-if)# spanning-tree port type ?
edge Consider the interface as edge port (enable portfast)
network Consider the interface as inter-switch link
normal Consider the interface as normal spanning tree port

should they be setup as normal on the cisco switch? and is there a setting on the palo to do the same?

Hi @M.Allen ,

Can you please elaborate more on your current design?

On the Cisco side, are the switchports connected to the Palo configured as access or trunk. On the Palo, are the interfaces operating in Layer 2, Layer 3, or vWire mode?
