snVLanByPortCfgStpMaxAge

1.3.6.1.4.1.1991.1.1.3.2.7.1.11

Syntax: Integer

Read-only

Shows the value of dot1dStpMaxAge, which is the maximum age that the STP information can exist before it is discarded. The STP information is learned from the network. The value of this object is in hundredths of a second, and is the actual value that this bridge is currently using.

(Refer to RFC 1493 Bridge MIB.)

snVLanByPortCfgStpHelloTime

1.3.6.1.4.1.1991.1.1.3.2.7.1.12

Syntax: Timeout

Read-only

Shows the value of dot1dStpHelloTime, which is the interval between the transmission of configuration bridge PDUs by this node. This value applies to any port when it is the root of the spanning tree or is trying to become the root. This is the actual value that this bridge is currently using.

This value is in hundredths of a second.

(Refer to RFC 1493 Bridge MIB.)

snVLanByPortCfgStpHoldTime

1.3.6.1.4.1.1991.1.1.3.2.7.1.13

Syntax: Integer32

Read-only

Shows the value of dot1dStpHoldTime, which is the interval when no more than two configuration bridge PDUs can be transmitted by this node. The interval is in units of hundredths of a second.

(Refer to RFC 1493 Bridge MIB.)

snVLanByPortCfgStpForwardDelay

1.3.6.1.4.1.1991.1.1.3.2.7.1.14

Syntax: Timeout

Read-only

Shows the value of dot1dStpForwardDelay, which 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 under way, to age all dynamic entries in the forwarding database.

Note: This value is the one that this bridge is currently using in contrast to dot1dStpBridgeForwardDelay, which is the value that this bridge and all others would start using should this bridge become the root. This value is measured in hundredths of a second. (Refer to RFC 1493 Bridge MIB.)
snVLanByPortCfgStpTimeSinceTopologyChange

1.3.6.1.4.1.1991.1.1.3.2.7.1.15

(Refer to RFC 1493 Bridge MIB.)

snVLanByPortCfgStpDesignatedRoot

1.3.6.1.4.1.1991.1.1.3.2.7.1.19

Syntax: BridgeId

Read-only

Shows the value of dot1dStpDesignatedRoot, which is the bridge identifier of the root of the spanning tree as determined by the Spanning Tree Protocol as executed by this node. This value is used as the root identifier parameter in all configuration bridge PDUs originated by this node.

(Refer to RFC 1493 Bridge MIB.)

snVLanByPortCfgBaseBridgeAddress

1.3.6.1.4.1.1991.1.1.3.2.7.1.20

Syntax: MAC address

Read-only

Shows the MAC address used by this bridge when it must be referred to in a unique fashion. It is recommended that this be the numerically smallest MAC address of all ports that belong to this bridge; however, it is only required to be unique. When concatenated with dot1dStpPriority, a unique bridge identifier is formed, which is used in the Spanning Tree Protocol.
