D-Link DES-3226 User Manual page 50

This group contains the objects that denote the bridge's state with
respect to the Spanning Tree Protocol. If a node does not implemented
the Spanning Tree Protocol, this group will not be
implemented.
The dot1dSr Group
This group contains the objects that describe the entity's state with
respect to source route bridging. If source routing is not supported this
group will not be implemented. This group is applicable to source route
only, and SRT bridges. This group will be described in a separate
document applicable only to source route bridging.
The dot1dTp Group
This group contains objects that describe the entity's state with respect
to transparent bridging. If transparent bridging is not supported this
group will not be implemented. This group is applicable to transparent
only and SRT bridges.
The dot1dStatic Group
This group contains objects that describe the entity's state with respect
to destination-address filtering. If destination-address filtering is not
supported this group will not be implemented. This group is applicable
to any type of bridge which performs destination-address filtering.
Relationship to Other MIBs
As described above, some IEEE 802.1d management objects have not
been included in this MIB because they overlap with objects in other
MIBs applicable to a bridge implementing this MIB. In particular, it is
assumed that a bridge implementing this MIB will also implement (at
least) the 'system' group and the 'interfaces' group defined in MIB-II.
Relationship to the 'system' group
In MIB-II, the 'system' group is defined as being mandatory for all
systems such that each managed entity contains one instance of each.
Bridge aging time can be adjusted in the Information window; otherwise Bridge
802.1 windows are read-only
