1.3.6.1.4.1.34751.9.253.6
Loop guard prevents alternate and root ports from becoming designated ports. In SSTP and PVST modes, if a Loop guard-enabled port is designated port, it is always blocked. In RSTP and MSTP modes, if a Loop guard-enabled port becomes designated port because of a failure that can't receive BPDUs, it is blocked.
