Port VLAN configuration table

snVLanByPortCfgStpForw
ardDelay
brcdIp.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
underway, 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 RFC1493 Bridge MIB.)

snVLanByPortCfgStpTime
SinceTopologyChange
brcdIp.1.1.3.2.7.1.15
Syntax: Time ticks

Read-only

Shows the time since the last topology change was detected by the
bridge entity. This time is in hundredths of a second.

snVLanByPortCfgStpTopC
hanges
brcdIp.1.1.3.2.7.1.16
Syntax: Counter

Read-only

Shows the total number of topology changes detected by this bridge
since the management entity was last reset or initialized.

snVLanByPortCfgStpRoot
Cost
brcdIp.1.1.3.2.7.1.17
Syntax: Integer

Read-only

Shows the value of dot1dStpRootCost, which is the cost of the path to
the root as seen from this bridge.
(Refer to RFC1493 Bridge MIB.)

snVLanByPortCfgStpRoot
Port
brcdIp.1.1.3.2.7.1.18
Syntax: Integer

Read-only

Shows the value of dot1dStpRootPort, which is the port number of the
port which offers the lowest cost path from this bridge to the root
bridge.
(Refer to RFC1493 Bridge MIB.)

snVLanByPortCfgStpDesi
gnatedRoot
brcdIp.1.1.3.2.7.1.19
Syntax: BridgeId

Read-only

Shows the 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 RFC1493 Bridge MIB.)

snVLanByPortCfgBaseBri
dgeAddress
brcdIp.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.

snVLanByPortCfgVLanNa
me
brcdIp.1.1.3.2.7.1.21
Syntax: DisplayString

Read-write

Shows the name of the VLAN community string.
Valid values: Up to 32 characters.

snVLanByPortCfgRouterI
ntf
brcdIp.1.1.3.2.7.1.22
Syntax: Integer

Read-write

This object is optional. It identifies the virtual interface for the router to
the VLAN, and applies only to the router. If an SNMP-Get value is zero,
that means this object was not configured.
