tions
brcdIp.1.1.3.5.1.1.7
Syntax: Integer32 None Shows the number of times this port has transitional from the
Learning state to the Forwarding state.
snPortStpPortState
brcdIp.1.1.3.5.1.1.8
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, whose state is forwarding(5). 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 bridge(s) 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.
snPortStpPortDesignatedCo
st
brcdIp.1.1.3.5.1.1.9
Syntax: Integer32 Read only The cost to the root bridge as advertised by the designated bridge
that is connected to this port. If the designated bridge is the root
bridge itself, then the cost is 0. The identity of the designated
bridge is shown in the Design Bridge field.
This value is compared to the Root Path Cost field in the
receivedbridge PDUs.
snPortStpPortDesignatedRo
ot
brcdIp.1.1.3.5.1.1.10
Syntax: BridgeId Read only The root bridge as recognized on this port. The value is the same as
the root bridge ID listed in the Root ID field.
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.
snPortStpPortDesignatedBri
dge
brcdIp.1.1.3.5.1.1.11
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.
snPortStpPortDesignatedPo
rt
brcdIp.1.1.3.5.1.1.12
Syntax: OctetString 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.
