I just saw this bit about RSTP detecting unidirectional links: http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/12-2SX/configuration/guide/book/spantree.html#wp1098785
Detecting Unidirectional Link Failure Using the dispute mechanism included in the IEEE 802.1D-2004 RSTP standard, the switch checks the consistency of the port role and state in the received BPDUs to detect unidirectional link failures that could cause bridging loops. When a designated port detects a conflict, it keeps its role, but reverts to a discarding (blocking) state because disrupting connectivity in case of inconsistency is preferable to opening a bridging loop. So I'm wondering if there's any reason to keep loop guard configured on a switch? Any current hardware that doesn't support rapidSTP? Some other reason??
