We have two EX4500's in a virtual chassis that form the core of our network. These are connected via fiber to our 22 edge data closets which all have stacks of EX4200's. The EX4500 runs layer 2 and 3 routing between about 30 different vlans. Out of the box, the EX series switches all have a bridge priority of 32768. On our core we have this in the config
Since the core switch has the lowest bridge priority, it is the Root Bridge. We are about to trade out the EX4500s for a stack of two EX4600s that will be the core of our network. Based on a previous post, I think that the EX4600 handles spanning-tree differently. Besides including the same rstp statement in the EX4600 config, is there something else I should be aware of with the EX4600 and spanning-tree?
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
