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.
We read that too but it is not working correctly in practice. A little more about our setup. We have two 4507's that are trunked together. The blade enclosure has two switches that are also trunked together via the internal fabric in the enclosure. The global config on 4507A is this:
Port 3/7 is connected to enclosure switch B. Currently both 4507's think they are the root for vlan 300 so that is problem 1. On the enclosure switches side A thinks that side B is the root, side be agrees with side A and also thinks it is root.
Spanning Tree Group 1: On VLANs: 1 300
Current Root: Path-Cost Port Hello MaxAge FwdDel Aging fde8 00:0f:6a:f3:14:00 4 17 2 20 15 180
We know that the legacy enclosure switches do not support rapid-pvst so we are suspecting that they are not sending the correct bpdu's to the 4507's and therefore they are not properly electing the 4507 as the root. If there is a way to manually set the port 3/7 to pvst instead of rapid-pvst I haven't been able to find out how to do it. If you know how to force the port on the 4507 to use pvst please share. If you have more questions please let me know.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
