Syntax

BridgeId

Source: BridgeId
Base type: 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.
