Introduction This memo defines a portion of the Management Information Base (MIB) used by Simple Network Management Protocol (SNMP) in GMPLS networks in patricular for Wavelength Switched Optical Networks (WSON) as defined in [RFC6163]. Those extensions were divided in two parts: generic constrains (as they can be easily applied to other technologies) and WSON specific contraints. This document aim to defines MIBs extentions to conver Galimberti, et al. Expires January 15, 2014 [Page 2] Internet-Draft GMPLS General Constrain MIB July 2013 only the generic constrain part. The WSON specific MIB extentions will be covered by a separate document [I-D.gmggm-ccamp-wson-snmp-mib]. As such, document [I-D.ietf-ccamp-general-constraint-encode] defines specific TLVs while [RFC6825] implement OSPF-TE related extentions. This MIB document aim to cover information defined in those general constrain drafts. [EDITOR NOTE] Very early draft to start MIB activity on GMPSL-WSON related extentions and collect feedback from working group. 2. The Internet-Standard Management Framework For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. 3. Conventions The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119] In the description of OIDs the convention: Set (S) Get (G) and Trap (T) conventions will describe the action allowed by the paramenter. 4. Overview Regarding exsting GMPLS MIBs modules, since the TED module [RFC6825] already provide and extention to previous GMPLS modules, we provide here a direct extention to it. Additional GMPLS MIB modules this document uses are [RFC4802] and [RFC4803]. Current GMPLS MIBs are covered by several documents. The most important to refererence here are the [RFC4802] and [RFC4803]. Most recent works on GMPLS MIBs is in [RFC6825], whenever possible this document will reuse the same approach. Galimberti, et al. Expires January 15, 2014 [Page 3] Internet-Draft GMPLS General Constrain MIB July 2013 General constrains can be classified in two broads categories: link information (as other GMPLS TED information) and Node information (this is different from what currently available). For link information the most similar definions are the ones from [RFC4803] where the label table is defined. For node information however, new specific information has to be defined. 5. Structure of the MIB Module Modules defined here provide additional information to existing GMPLS MIBS in order to represent the general constrains information as reported in [I-D.ietf-ccamp-general-constraint-encode]. This module is organized into two tables as reported in the following sub sections. 5.1. gmplsGenConsAvailableLabelsTable This object represent the Labels availability as defined by [I-D.ietf-ccamp-general-constraint-encode] section 2.3. This information may be introduced by specific technologies but is represented in a general form. An application example is [draft- ietf-ccamp-wson-signal-compatibility-ospf] that advertise such information under its specific ISC values. The table entry is composed by: o gmplsGenConsLabelIndex (type: Unsigned 32) o gmplgGenConsLabelInterface (type: typesInterfaceIndexOrZero) o gmplsGenConsISCD (type: IANAGmplsSwitchingTypeTC needs to be properly extended). [EDITOR NOTE1: could we assume that ISCD=151 for WSON hence the associated label follows RFC6205. Likely flexgrid will have the same constrain.] [EDITOR NOTE2: we could probably add an index reference to the tedSwCabTable so we have all switching capability info through one pointer.] o gmplsGenConsLabelValue (type: a value that might be greater than 32 bits, not sure about max length). Value format may vary upon the ISCD however the generic label format defined in the past still apply. A type might be reused could be (gmplsLabelPortWavelength Unsigned32) defined in GMPLS LSR MIB. However we need to support labels bigger than 32 bits. Depending on switching capability available on an interface, this table MUST initialized with all possible available labels values. As Galimberti, et al. Expires January 15, 2014 [Page 4] Internet-Draft GMPLS General Constrain MIB July 2013 long an tunnels are created and labels are used, the existing gmplsLabelTable defined in [RFC4803], is filled up while entries are removed from this gmplsGenConsAvailableLabelsTable. 5.2. gmplsGenConsSharedBackupLabelsTable The purpose of shared backup labels is defined in [I-D.ietf-ccamp-general-constraint-encode]. As in the previous case the information is advertised through the specific ISCD. The entry for this table is equal to definitions in Section 5.1 hence we have the same table format. 5.3. gmplsGenConsConnMatrixTable The Connectivity Matrix indicates the Node constraints introduced by [I-D.ietf-ccamp-general-constraint-encode] as additional constrains compared to link/label constrains. The table entry shall have the following information: o An identifier of the local node. E.g. tedLocalRouterId (type: TedRouterIdTC). o Connectivity Matrix Type (1: RWA, 2: Optical Impairments) o Connectivity Matrix ID: the unique identifier for the current connectivity matrix. Type: integer. o Link Ingress: (Type: TedLinkIndexTC) the link identifier for the ingress link (ingress and egress link identify a possible connectivty for the node). o Link Egress: (Type: TedLinkIndexTC) the link identifier for the egress link (ingress and egress link indentify a possible connectivty for the node). 5.4. gmplsGenConsPortLabelRestrictionTable This table the port label constraints introduced by [I-D.ietf-ccamp-general-constraint-encode] as an additional constrains on the port or vs permitted labels. This constrains related to the connectivity matrix (from previous section) and are advertised through [I-D.ietf-ccamp-gmpls-general-constraints-ospf-te]. The entry for this table has the following elements: Galimberti, et al. Expires January 15, 2014 [Page 5] Internet-Draft GMPLS General Constrain MIB July 2013 o An identifier for the local node. E.g. tedLocalRouterId (type: TedRouterIdTC). o Connectivity matrix id: an index in the previous table o Restriction Type (Values: 0 Simple Label, 1 Channel Count, 2 Label Range1, 3 Simple Label and Channel Count, 4 Link Label Exclusivity) o Label Set: used depending on restriction type o Max Channel Count / Max Label Set (Integer): used depending on restriction type o Link Set: used depending on restrictio type 6.

Security Considerations There are a number of management objects defined in this MIB module with a MAX-ACCESS clause of read-write and/or 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. These are the tables and objects and their sensitivity/vulnerability: Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. SNMP versions prior to SNMPv3 did not include adequate security. 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 module. Galimberti, et al. Expires January 15, 2014 [Page 12] Internet-Draft GMPLS General Constrain MIB July 2013 It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy). Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module 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. 9. IANA Considerations Option #1: The MIB module in this document uses the following IANA-assigned OBJECT IDENTIFIER values recorded in the SMI Numbers registry: Descriptor OBJECT IDENTIFIER value ---------- ----------------------- sampleMIB { mib-2 XXX } Option #2: Editor's Note (to be removed prior to publication): the IANA is requested to assign a value for "XXX" under the 'mib-2' subtree and to record the assignment in the SMI Numbers registry. When the assignment has been made, the RFC Editor is asked to replace "XXX" (here and in the MIB module) with the assigned value and to remove this note. Note well: prior to official assignment by the IANA, an internet draft MUST use placeholders (such as "XXX" above) rather than actual numbers. See RFC4181 Section 4.5 for an example of how this is done in an internet draft MIB module. Option #3: This memo includes no request to IANA. 10. Contributors to be added. Galimberti, et al.
