stpOptfPortFast |
1.3.6.1.4.1.3320.9.253.1 |
Port Fast immediately brings a port to the forwarding state from a blocking state, bypassing the listening and learning states. |

stpOptfBpduGuard |
1.3.6.1.4.1.3320.9.253.2 |
BPDU guard can operate in all spanning tree modes, but the feature operates with some differences.
In SSTP and PVST modes, if a Port Fast-enabled port receives a BPDU,it will be shutdown.
In RSTP and MSTP modes, if a port receives a BPDU, it will be blocked for double forward time.
In all spanning tree modes, a BPDU guard-enabled port will not send BPDUs. |

stpOptfBpduFilter |
1.3.6.1.4.1.3320.9.253.3 |
This feature prevents ports from sending BPDUs. If a BPDU is received on a Port Fast-enabled port,
the port loses its Port Fast-operational status,and BPDU filtering is disabled. |

stpOptfUplinkFast |
1.3.6.1.4.1.3320.9.253.4 |
UplinkFast can accelerate the choice of a new root port when a link or switch fails or when the spanning
tree reconfigures itself. The root port transitions to the forwarding state immediately without going through
the listening and learning states, as it would with the normal spanning-tree procedures. |

stpOptfBackboneFast |
1.3.6.1.4.1.3320.9.253.5 |
BackboneFast detects indirect failures in the core of the backbone.
When a switch receives an inferior BPDU from the designated port of another switch,
the BPDU is a signal that the other switch might have lost its path to the root,
and BackboneFast tries to find an alternate path to the root. |

stpOptfLoopGuard |
1.3.6.1.4.1.3320.9.253.6 |
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. |

stpPortOptfRootLoopGuard |
1.3.6.1.4.1.3320.9.253.7.1.5 |
Root Guard prevents a port that is receiving superior BPDUs from becoming root port.
In SSTP and PVST modes, if a Root Guard-enabled port is receiving superior BPDUs, it is always blocked.
In RSTP and MSTP modes, if a Root Guard-enabled port originally didn't receive superior BPDUs, but now
it is receiving superior BPUDs, it is blocked.
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. |
