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." ::= { stp 2 } stpOptfBpduFilter OBJECT-TYPE SYNTAX INTEGER{ True(1), False(2) } ACCESS read-write STATUS mandatory DESCRIPTION "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. " ::= { stp 3 } stpOptfUplinkFast OBJECT-TYPE SYNTAX INTEGER{ True(1), False(2) } ACCESS read-write STATUS mandatory DESCRIPTION "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." ::= { stp 4 } stpOptfBackboneFast OBJECT-TYPE SYNTAX INTEGER{ True(1), False(2) } ACCESS read-write STATUS mandatory DESCRIPTION "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. " ::= { stp 5 } stpOptfLoopGuard OBJECT-TYPE SYNTAX INTEGER{ True(1), False(2) } ACCESS read-write STATUS mandatory DESCRIPTION "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." ::= { stp 6 } stpPortOptfTable OBJECT-TYPE SYNTAX SEQUENCE OF StpPortOptfTableEntry ACCESS not-accessible STATUS mandatory DESCRIPTION "A table of stpPortOptf operation." ::= { stp 7 } stpPortOptfTableEntry OBJECT-TYPE SYNTAX StpPortOptfTableEntry ACCESS not-accessible STATUS mandatory DESCRIPTION "A collection of Stp Port Optf operation."

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." ::= { stpPortOptfTableEntry 5 } END
