Is there any way to enable all interfaces on an EX4600 for Spanning Tree Protocol (STP) with a single command?
I am not sure what you mean by this
"PS if you run the EX4600 in a VC then change the access interfaces to ae and remove the SPT which has up to 6 seconds of convergence-time"
Nearly all of our edge data closets have stacks of EX4200 switches. We have a fiber connection to the top of the stack and the bottom of the stack. The fiber runs to our EX4500 stack to complete the connection. These are setup as LACP aggregate interfaces. We have few edge data closests that only have 1 switch so a single fiber connection to the core
