1 Overview of ifIndex

RFC2863 (RFC1213) defines ifTable MIB to manage various types of interfaces provided by devices in the network in a unified manner. In ifTable, the ifIndex is defined as the index of every interface. As defined in RFC2863, ifIndex ranges from 1 to ifNumber (the number of interfaces currently provided by a device in a network). In addition, ifNumber maps an interface uniquely in the stable period (that is, from the current system start to the next system start). Note that RFC does not define meanings of interfaces; therefore, the interfaces can be specific physical interfaces or abstract network interfaces. Working as the network access product, the MA5600T&MA5603T supports a large number of services that are configured based on different interfaces, such as ADSL, SHDSL, and Ethernet interfaces. Therefore, generally, the network device interfaces of the MA5600T&MA5603T that map ifTable are specific interfaces; however, there are also abstract network interfaces. In addition, there are various types of interfaces for service access. To facilitate unified management, the indexes of different types of physical interfaces are encoded in a systematic manner in the MA5600T&MA5603T. In this case, the range of ifIndex displayed on the MA5600T&MA5603T is not subject to 1ifNumber.2 ifIndex Encoding Rules

This chapter describes the ifIndex encoding rules based on different interfaces.2.1 Encoding Element

Generally, the ifIndex of an interface of the MA5600T&MA5603T depends on the following elements: Internal interface

Shelf ID of the interface, ranging from 0 to 1 (currently, only 0 is used and 1 is reserved for expansion.) Slot ID of the interface, ranging from 0 to 22

Sequence number (SN) of the interface (for value range, see 2.2

REF _Ref255560525 \h \* MERGEFORMAT Encoding Rules) (Here, the SN can be a port ID, or a VLAN ID, or IMA group ID or IMA link ID.)

Interface parameter (for parameters, see 2.2

REF _Ref255560525 \h \* MERGEFORMAT Encoding Rules) (currently, this element is used for only xDSL channel interfaces)

The ifIndex encoding of an interface is a 32-bit digit. The sequence of the preceding five elements in the ifIndex encoding is encoding, shelf ID, slot ID, SN, and parameter in a descending order.

In the ifIndex encoding, the SN refers to the ID of the interface such as the ADSL interface, SHDSL interface, and Ethernet interface. In the case of the abstract interface, the SN is the index of the system resource because the interface does not have the mapping interface. The Ethernet VLAN interface is such an interface.

To configure the encoding rules, the shelf and slot IDs of the Ethernet VLAN interface invariably use the shelf ID and slot ID of the active control board, and the SN of the Ethernet VLAN interface is the index of the VLAN.

The Ethernet VLAN interface is used for only creating the service interface and is invisible in ifTable and ifXTable.

If the Shelf ID is equal to or larger than 32, the rules for the following internal interface encoding are extended. Specifically, the Shelf ID occupies 9 bits and the most significant bit is 1. Bits occupied by Slot ID and Port ID remain the same. For details, see the following.InterfaceEncoding Rules

In the case of the abstract interface, the ifIndex is the index of the system resource allocated from internal index pool because the interface does not provide the fixed encoding rule. The Ethernet VLAN L3 interface & loopback interface & null interface are such interfaces, so for these abstract interfaces the encoding rule is invisible for OSS system.The MA5600T&MA5603T system provides a query interface (get) in MIB for VLAN L3 interface & loopback interface & null interface so that the operator/OSS can use this query interface to get ifIndex for specific L3 interface or loopback interface.

For details of query interface, see chapter 1.6.9 in the HUAWEI-ANSOI-INTERFACE.Configure the MA5600T&MA5603T through the OSS system, if the ifindex recorded in the operation log of the MA5600T&MA5603T system is a negative value, the ifindex is converted to Integer32. Then, need to convert the value to Unsigned Integer32 to show a correct ifindex.2.3 Internal Interface
