2. 2 © 2002, Cisco Systems, Inc. All rights reserved. Motivation Fit within the architecture defined [PWMIB], PWE3 ATM Encapsulation draft, and PWE3 Framework. Works with any supported PSN. Fit within the model for VC definition/management as defined in the [AToM] MIB. MIB supports automatically and manually configured ATM VCs The MIB supports point-to-point ATM VC connections.

3. 3 © 2002, Cisco Systems, Inc. All rights reserved. Motivation (cont) Point-to-multipoint and multipoint-to-point connections are for future study. The MIB allows configuration of all the parameters needed to establish a PW ATM VC. The MIB reports: ATM performance metrics for the PW ATM VC.

PW VC ATM Inbound Table This Table is used to configure a inbound ATM VC Entry. PW VC ATM Outbound Perf Table This Table contains the statistics for an ATM VC Entry in the outbound direction PW VC ATM Inbound Perf Table This Table contains the statistics for an ATM VC Entry in the inbound direction

6. 6 © 2002, Cisco Systems, Inc. All rights reserved. Open Issues A TrafficParamDescr Table is not defined as part of this MIB so that users can refer to any ATM TrafficDescr Table (e.g atmTrafficDescrParamTable present in the [AToM] MIB) The MIB does not consider ILMI support, should it?
