DESCRIPTION

"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."

"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. "

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."

|
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. "

|
|

|
In RSTP and MSTP modes, if a Loop guard-enabled port becomes designated port because of a failure
