AbstractStpInstance

public abstract class AbstractStpInstance

Properties
bridgeForwardDelay The value that all bridges use for ForwardDelay when this bridge is acting as the root. Note that 802.1D-1990 specifies that the range for this parameter is related to the value of bridgeMaxAge. The granularity of this timer is specified by 802.1D-1990 to be 1 second. An agent may return a badValue error if a set is attempted to a value which is not a whole number of seconds

type=int
default=15
minimum=4
maximum=30
units=seconds
bridgeHelloTime The value that all bridges use for HelloTime when this bridge is acting as the root. The granularity of this timer is specified by 802.1D- 1990 to be 1 second. An agent may return a badValue error if a set is attempted to a value which is not a whole number of seconds

type=int
default=2
minimum=1
maximum=10
units=seconds
bridgeMaxAge The value that all bridges use for MaxAge when this bridge is acting as the root. Note that 802.1D-1990 specifies that the range for this parameter is related to the value of bridgeHelloTime. The granularity of this timer is specified by 802.1D-1990 to be 1 second. An agent may return a badValue error if a set is attempted to a value which is not a whole number of seconds.

type=int
default=20
minimum=6
maximum=40
units=seconds
bridgeMode The mode of the Spanning Tree Protocol activated on this bridge.

type=layer2.StpBridgeMode
access=read-only
default=onePerVlan
designatedRoot The bridge identifier of the root of the spanning tree as determined by the Spanning Tree Protocol as executed by this instance. This value is used as the Root Identifier parameter in all Configuration Bridge PDUs originated by this node for this instance

type=MacAddress
access=read-only
default=00-00-00-00-00-00
forwardDelay This time value, measured in units of hundredths of a second, controls how fast a port changes its spanning state when moving towards the Forwarding state. The value determines how long the port stays in each of the Listening and Learning states, which precede the Forwarding state. This value is also used, when a topology change has been detected and is underway, to age all dynamic entries in the Forwarding Database. (Note that this value is the one that this instance is currently using, in contrast to bridgeForwardDelay which is the value that this instance and all others would start using if/when this bridge were to become the root.)

type=int
access=read-only
default=0
units=seconds
helloTime The amount of time between the transmission of Configuration bridge PDUs by this instance on any port when it is the root of the spanning tree or trying to become so, in units of hundredths of a second. This is the actual value that this instance is currently using.

type=int
access=read-only
default=0
units=seconds
holdTime This time value determines the interval length during which no more than two Configuration bridge PDUs shall be transmitted by this instance, in units of hundredths of a second.

type=int
access=read-only
default=0
units=seconds
id Specifies the Spanning Tree Instance.

type=int
access=read-create
minimum=0
maximum=4095
Mandatory on create
insAutoVlanContainment The current enabled status for this instance of the Auto Vlan containment feature which controls path costs in MSTP.

type=layer2.StpBridgeEnableDisable
default=disabled
insBpduSwitching When this field is enabled, the BPDUs received for this instance to be switched when spanning tree is disabled. When the field is disabled, the BPDUs received on this instance will be dropped if spanning tree is disabled.

type=layer2.StpBridgeEnableDisable
default=disabled
insBridgeTxHoldCount A limit controlling the number of PDUs transmitted per port per second for this instance.

type=int
default=6
minimum=1
maximum=10
insMode The current mode of the Spanning Tree Protocol this instance is a part of.

type=layer2.StpBridgeMode
default=onePerVlan
maxAge The maximum age of Spanning Tree Protocol information learned from the network on any port before it is discarded, in units of hundredths of a second. This is the actual value that this spanning tree instance is currently using.

type=int
access=read-only
default=0
units=seconds
priority Specifies the priority of this specific Spanning Tree Instance. It is used as the highest 4 bits of the Bridge ID included in the STP BPDU's generated by this bridge. The priority can only take-on values which multiples of 4096 (4k). If a value is specified which is not a multiple of 4K, then this value will be replaced by the closest multiple of 4K which is lower than the value entered.

type=int
default=32768
minimum=0
maximum=65535
rootCost The cost of the path to the root as seen from this bridge for this spanning tree instance.

type=int
access=read-only
rootPort The ifindex of the port which offers the lowest cost path from this bridge to the root bridge for this spanning tree instance.

type=int
access=read-only
default=0
serviceId The local service ID (may be different from the global svcComponentId).

type=long
access=read-only
default=0
siteId

type=string
access=read-only
default=0.0.0.0
maximum=50
stpProtocol The value indicates whether stp, rstp or mstp is running on this instance.

type=l2fwd.StpProtocol
default=stp
svcComponentId

type=long
access=read-only
default=0
