I am replacing a 6120 blade switch with 6127XLG. With the 6120 I had bpdu filter configured for an uplink port so it drops bpdus sent on the uplink interface connected to a switch which has a bpduguard enabled. However, the 6127 does not have a bpdu filter option but instead it has bpdu drop, which I am assuming should do the same thing. In fact, it seems to keep forwading the bpdus up the port connected to the switch with the bpduguard enabled, since the port immediately transitions to Error Disabled. I ended up disabling the STP on the port to workaround this.
Anyone knows why it's not working and what else I can do with keeping stp enabled?
