This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP based internets. In particular it defines objects for managing a client of the Common Open Policy Service (COPS) protocol.
This memo includes a MIB module in a manner that is compliant to the SMIv2 [V2SMI].
The SNMP Management Framework presently consists of five major components:
A more detailed introduction to the current SNMP Management Framework can be found in RFC 2570 [V3INTRO].
Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A MIB conforming to the SMIv1 can be produced through the appropriate translations. The resulting translated MIB must be semantically equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable information in SMIv2 will be converted into textual descriptions in SMIv1 during the translation process. However, this loss of machine readable information is not considered to change the semantics of the MIB.
The COPS protocol [COPS] is a client-server protocol intended for the communication of policy requests and decisions between a Policy Enforcement Point (PEP) and a Policy Decision Point (PDP). The PEP acts as a COPS client in this scenario. The model for policy out- sourcing, of which the COPS protocol provides one part, is described in [FRAMEWORK].
This MIB is intended to provide management of the important features of a COPS protocol client module. It does not provide management for a COPS server - this is outside the scope of the current memo. It provides for monitoring of status and protocol statistics, as well as for configuration of the client, in particular for telling it where to locate its servers. Other mechanisms for achieving this function without SNMP configuration might include use of the Service Location Protocol [SRVLOC] although this is outside the scope of this memo and are not specified by the COPS protocol itself.
This MIB also does not provide management of specific COPS client- types e.g., for use with the RSVP protocol [RSVP][COPSRSVP].
Objects in this MIB are arranged into groups. Each group is organized as a set of related objects. The overall structure is described below.
This group contains objects that represent COPS protocol capabilities implemented by this COPS client.
This group contains objects that indicate the current status of connection(s) to COPS servers, including per-server protocol statistics. It maintains last-known statistics for all of the servers with which the client has ever been connected since agent restart.
This group contains objects that allow for configuration of COPS server addresses and the order to which connections should be attempted. It contains a table of per-server objects as well as scalars for configuration of the retry algorithm to be used by a client to obtain a connection to an appropriate server.
The datatypes CopsClientState, CopsServerEntryType, CopsErrorCode, CopsTcpPort and CopsAuthType are used as textual conventions in this document. These textual conventions have NO effect on either the syntax nor the semantics of any managed object. Objects defined using these conventions are always encoded by means of the rules that define their primitive type. Hence, no changes to the SMI or the SNMP are necessary to accommodate these textual conventions which are adopted merely for the convenience of readers.
This MIB contains definitions for a single COPS protocol client represented by a single SNMP agent and instance of the MIB-2 system group [MIB2]. It does not address the case of multiple co-located COPS protocol clients.

This document describes instrumentation for the client side of the COPS protocol which was defined by the RSVP Admission Policy (rap) Working Group, now known as the Resource Allocation Protocol (rap) Working Group.
There are a number of management objects defined in this MIB that have a MAX-ACCESS clause of read-create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations.
SNMPv1 by itself is not a secure environment. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB.
It is recommended that the implementers consider the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model [USM] and the View-based Access Control Model [VACM] is recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, is properly
configured to give access to the objects only to those principals
(users) that have legitimate rights to indeed GET or SET
(change/create/delete) them.
