Similarly, all representations of Bridge-Id in this MIB Module use, as a textual convention (i.e. this convention does not affect their encoding)" SYNTAX OCTET STRING (SIZE (6)) BridgeId ::= TEXTUAL-CONVENTION STATUS current 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-1998 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." SYNTAX OCTET STRING (SIZE (8)) Timeout ::= TEXTUAL-CONVENTION DISPLAY-HINT "d" STATUS current DESCRIPTION "A Spanning Tree Protocol (STP) timer in units of 1/100 seconds. 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 hundredths 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-1998 specifies a settable granularity of no more than one second for these timers. To avoid ambiguity, a conversion algorithm is defined below for converting between the different units, which ensures a timer's value is not distorted by multiple conversions. To convert a Timeout value into a value in units of 1/256 seconds, the following algorithm should be used: b = floor( (n * 256) / 100) where: floor = quotient [ignore remainder] n is the value in 1/100 second units b is the value in 1/256 second units To convert the value from 1/256 second units back to 1/100 seconds, the following algorithm should be used: n = ceiling( (b * 100) / 256) where: ceiling = quotient [if remainder is 0], or quotient + 1 [if remainder is nonzero] n is the value in 1/100 second units b is the value in 1/256 second units Note: it is important that the arithmetic operations are done in the order specified (i.e., multiply first, divide second)."
