Object
scalar BridgeId
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.

OctetString
Type Description
The Bridge-Identifier as used in the Spanning Tree Protocol to uniquely identify a bridge. Its first two octets (in network byte order) contain a priority value and its last 6 octets contain the MAC address used to refer to a bridge in a unique fashion (typically, the numerically smallest MAC address of all ports on the bridge). Several objects in this MIB module represent values of timers used by the Spanning Tree Protocol. In this MIB, these timers have values in units of hundreths of a second (i.e. 1/100 secs). These timers, when stored in a Spanning Tree Protocol's BPDU, are in units of 1/256 seconds. Note, however, that 802.1D-1990 specifies a settable granularity of no more than 1 second for these timers. To avoid ambiguity, a data type is defined here as a textual convention and all representation of these timers in this MIB module are defined using this data type. An algorithm is also defined for converting between the different units, to ensure a timer's value is not distorted by multiple conversions.
