We are bringing up an hp pclass blade enclosure in our dmz. Historically our dual 4507's for our dmz have been running rapid-pvst but the hp
pclass enclosure software rev does not support rapid-pvst. Before we change the mode back to pvst we want to understand the impact to our switches and the servers connected to them. This is the first enclosure we will have in our dmz as all other servers are regular rackmount type with dual nic's with one nic home run back to each of the two dmz switches. Primarily, will we create any loops during the changes and if so is there anything we can do to prevent it or will stp simply converge without issue. All feedback and links to documentation are appreciated.
