By convention, objects -- with this syntax are declared as having -- -- SIZE (0..255) PhysAddress ::= OCTET STRING -- This data type is used to model media addresses. For many -- types of media, this will be in a binary representation. -- For example, an ethernet address would be represented as -- a string of 6 octets. -- All representations of MAC addresses in this MIB Module use, -- as a textual convention (i.e. this convention does not affect -- their encoding), the data type: MacAddress ::= OCTET STRING (SIZE (6)) -- a 6 octet address in -- the "canonical" order -- defined by IEEE 802.1a, i.e., as if it were transmitted least -- significant bit first, even though 802.5 (in contrast to other -- 802.x protocols) requires MAC addresses to be transmitted most -- significant bit first. -- -- 16-bit addresses, if needed, are represented by setting their -- upper 4 octets to all 0's, i.e., AAFF would be represented -- as 00000000AAFF. -- Similarly, all representations of Bridge-Id in this MIB Module -- use, as a textual convention (i.e. this convention does not affect -- their encoding), the data type: BridgeId ::= OCTET STRING (SIZE (8)) -- 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/D9 -- 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. -- The data type is: Timeout ::= INTEGER -- a STP timer in units of 1/100 seconds -- 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 non-zero] -- 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). -- -- SNMP system group added to make things easier from a NM console -- -- system OBJECT IDENTIFIER ::= { mib-2 1 } chipcom OBJECT IDENTIFIER ::= { enterprises 49 } chipmib02 OBJECT IDENTIFIER ::= { chipcom 2 } chipGen OBJECT IDENTIFIER ::= { chipmib02 1 } chipEcho OBJECT IDENTIFIER ::= { chipmib02 2 } chipProducts OBJECT IDENTIFIER ::= { chipmib02 3 } chipExperiment OBJECT IDENTIFIER ::= { chipmib02 4 } oebm OBJECT IDENTIFIER ::= { chipProducts 2 } midnight OBJECT IDENTIFIER ::= { chipProducts 3 } dot1dBridge OBJECT IDENTIFIER ::= { chipExperiment 14 } -- the System group -- Implementation of the System group is mandatory for all -- systems.
