| switchBridgeMib | 1.3.6.1.4.1.207.8.9.2.2.5 | | | The MIB module for bridge and spanning tree protocol. This
mib is based on RFC 1493 with modifications to support
multiple bridges, one for each virtual LAN (VLAN), in one
physical chassis. The bridge protocol attributes are now in
a table indexed by the vLanNumber. The port number used to
index various tables is now a virtual port number
corresponding to the virtual port defined in the
SWITCH-VLAN-MIB. |

of switchBridgeBasePortIfIndex as another port on the
same bridge, this object contains the name of an

value might identify an (e.g., the first) object

corresponding to this port.
For a port which has a unique value of
switchBridgeBasePortIfIndex, this object can have the
value { 0 0 }. |

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 bridge is
currently using, in contrast to
switchBridgeStpBridgeForwardDelay which is the value that

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. |

application of the Spanning Tree Protocol. This
state controls what action a port takes on
reception of a frame. If the bridge has detected
a port that is malfunctioning it will place that
port into the broken(6) state. For ports which
are disabled (see switchBridgeStpPortEnable), this object
will have a value of disabled(1). |
| INT switchBridgeStpPortEnable | 1.3.6.1.4.1.207.8.9.2.2.5.2.15.1.4 | INTEGER | read-write | The enabled/disabled status of the port. |

counter is increasing, it indicates that the
Forwarding Database is regularly becoming full (a
condition which has unpleasant performance effects
on the subnetwork). If this counter has a
significant value but is not presently increasing,
it indicates that the problem has been occurring
but is not persistent. |

being used to determine if and how
frames addressed to the value of
the corresponding instance of
switchBridgeTpFdbAddress are being

(e.g., it was learned but has since
aged-out), but has not yet been

configured into the bridge by (local or network)
management specifying the set of ports to which
frames received from specific ports and containing
specific destination addresses are allowed to be
forwarded. The value of zero in this table as the

1 through 8, the second octet specifying ports 9
through 16, etc. Within each octet, the most
significant bit represents the lowest numbered
port, and the least significant bit represents the
highest numbered port. Thus, each port of the
bridge is represented by a single bit within the
value of this object. If that bit has a value of
'1' then that port is included in the set of
ports; the port is not included if its bit has a
value of '0'. |

as the new root, e.g., upon expiration of the
Topology Change Timer immediately subsequent to
its election. Implementation of this trap is
optional. |
| NTF switchTopologyChange | 1.3.6.1.4.1.207.8.9.2.2.5.6.0.2 | | | A topologyChange trap is sent by a bridge when
any of its configured ports transitions from the
