wfAtmDxiTable 1.3.6.1.4.1.18.3.5.9.5.15

The ATM DXI Table - An entry in this table is either resident in the Wellfleet MIB or in the Digital Link MIB via the SNMP Proxy. The Component attribute determines local or remote residency. The ATM Data Exchange Interface (DXI) object reflects information about an ATM DXI interface between an ATM DSU and a Router/Host. In particular, it contains both configuration and performance information specific to the DXI (ATM) interface. Each DXI instance typically corresponds to several (ATM) DXIADDRs. The DXI object optionally keeps some information on a per-DXIADDR basis. Each instance of the DXI object typically has only one corresponding ATM -AAL object, but the MIB has been structured so that a DXI may have more than one. It should be noted that in the DXI MIB, the receive (transmit) direction refers to data received from (transmitted to) the ATM interface. With a 23-bit DXIADDR, the range of valid DXIADDR index values is 1 thru 2**23 inclusive. Note that the 23-bit binary DXIADDR field (with values 0 thru 2**23-1) from the Frame Relay header must be incremented by one to yield the DXIADDR index for accessing the tables in the MIB. The DXIADDR consisting of all zeros (with corresponding MIB index value of 1) is reserved for the DXI Local Management Interface (LMI) with the DSU. DxiAddr ::= INTEGER (1..8388608) ** For DL200 and DL3200 DSUs, there is only one ATM DXI per DSU ** and only one AAL object (specifically VBR) per ATM DXI. ** For these products, the mapping between the DXI (Frame Relay) ** DXIADDR and the ATM VPI/VCI is fixed. The LMI DXIADDR has no ** corresponding VPI/VCI. Otherwise, the eight most significant ** bits of the DXIADDR map into the the VPI (the eight most ** significant bits of the VPI/VCI), the fifteen least ** significant bits of the DXIADDR map into the fifteen least ** significant bits of the VCI, and the most significant bit of ** the VCI is set to zero.
