Port STP configuration groups
snIfStpPortState
brcdIp.1.1.3.5.2.1.8
Syntax: Integer Read-only Shows the port’s current state as defined by application of the
Spanning Tree Protocol. This state controls what action a port
takes when it receives a frame:
•
disabled(1) – The port is not participating in STP. This can
occur when the port is disconnected or STP is disabled on the
port.
•
blocking(2) – STP has blocked Layer 2 traffic on this port to
prevent a loop. The device or VLAN can reach the root bridge
using another port with the forwarding(5) state. When a port
is in this state, the port does not transmit or receive user
frames, but the port does continue to receive STP BPDUs.
•
listening(3) – STP is responding to a topology change and this
port is listening for a BPDU from neighboring bridges in order
to determine the new topology. No user frames are
transmitted or received during this state.
•
learning(4) – The port has passed the listening state and will
change to the blocking or forwarding state, depending on the
results of STP’s reconvergence. The port does not transmit or
receive user frames during this state. However, the device
can learn the MAC addresses of frames that the port receives
during this state and make corresponding entries in the MAC
table.
•
forwarding(5) – STP is allowing the port to send and receive
frames.
•
broken(6) – Ports that are malfunctioning are placed into this
state by the bridge.
•
preforwarding(7)
snIfStpPortDesignatedCost
brcdIp.1.1.3.5.2.1.9
Syntax: Integer32 Read-only The cost to the root bridge as advertised by the designated bridge
that is connected to this port. This value is compared to the Root
Path Cost field in received bridge PDUs.
snIfStpPortDesignatedRoot
brcdIp.1.1.3.5.2.1.10
Syntax: BridgeId Read-only Shows the unique ID of the root bridge. The root bridge is recorded
as the root in the configuration BPDUs, which are transmitted by
the designated bridge for the segment to which the port is
attached.
snIfStpPortDesignatedBridge
brcdIp.1.1.3.5.2.1.11
Syntax: BridgeId Read-only Shows the ID of the designated bridge. The designated bridge is
the device that connects the network segment to the root bridge.
snIfStpPortDesignatedPort
brcdIp.1.1.3.5.2.1.12
Syntax: OCTET STRING Read-only Shows the ID of the port on the designated bridge that connects to
the root bridge on the network.
This object has two octets.
snIfStpPortAdminRstp
brcdIp.1.1.3.5.2.1.13
Syntax: TruthVal Read-write Enables or disables RSTP of a port which is a member of a VLAN. If
the VLAN is not operating in RSTP, this object will return FALSE(2)
and this object is not writable.
snIfStpPortProtocolMigration
brcdIp.1.1.3.5.2.1.14
Syntax: TruthVal Read-write When operating in RSTP (version 2) mode, writing TRUE(1) to this
object forces this port to transmit RSTP BPDUs. Any other
operation on this object has no effect and it always returns
FALSE(2) when read.
snIfStpPortAdminEdgePort
brcdIp.1.1.3.5.2.1.15
Syntax: TruthVal Read-write The administrative value of the edge port parameter. A value of
TRUE(1) indicates that this port should be assumed as an edge
port and a value of FALSE(2) indicates that this port should be
assumed as a non-edge port.
