Defined Values

stp 1.3.6.1.4.1.3320.9.253
OBJECT IDENTIFIER    

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.
Status: mandatory Access: read-write
OBJECT-TYPE    
  INTEGER true(1), false(2)  

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.
Status: mandatory Access: read-write
OBJECT-TYPE    
  INTEGER true(1), false(2)  

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.
Status: mandatory Access: read-write
OBJECT-TYPE    
  INTEGER true(1), false(2)  

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.
Status: mandatory Access: read-write
OBJECT-TYPE    
  INTEGER true(1), false(2)  

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.
Status: mandatory Access: read-write
OBJECT-TYPE    
  INTEGER true(1), false(2)  

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.
Status: mandatory Access: read-write
OBJECT-TYPE    
  INTEGER true(1), false(2)  

stpPortOptfTable 1.3.6.1.4.1.3320.9.253.7
A table of stpPortOptf operation.
Status: mandatory Access: not-accessible
OBJECT-TYPE    
  SEQUENCE OF  
    StpPortOptfTableEntry

stpPortOptfTableEntry 1.3.6.1.4.1.3320.9.253.7.1
A collection of Stp Port Optf operation.
Status: mandatory Access: not-accessible
OBJECT-TYPE    
  StpPortOptfTableEntry  

stpPortOptfPortFast 1.3.6.1.4.1.3320.9.253.7.1.1
Port Fast immediately brings a port to the forwarding state from a blocking state, bypassing the listening and learning states.
Status: mandatory Access: read-write
OBJECT-TYPE    
  INTEGER no(0), enabled(1), disabled(2)  

stpPortOptfBpduGuard 1.3.6.1.4.1.3320.9.253.7.1.2
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.
Status: mandatory Access: read-write
OBJECT-TYPE    
  INTEGER no(0), enabled(1), disabled(2)  

stpPortOptfBpduFilter 1.3.6.1.4.1.3320.9.253.7.1.3
This featue 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.
Status: mandatory Access: read-write
OBJECT-TYPE    
  INTEGER no(0), enabled(1), disabled(2)  

stpPortOptfLoopFast 1.3.6.1.4.1.3320.9.253.7.1.4
This feature is used to minimize the convergence time in RSTP mode.
Status: mandatory Access: read-write
OBJECT-TYPE    
  INTEGER no(0), enabled(1), disabled(2)  

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.
Status: mandatory Access: read-write
