A SNMP MIB to manage GMPLS TED with WSON specific support
draft-gmggm-ccamp-wson-snmp-mib-00
Abstract
This memo defines a portion of the Management Information Base (MIB)
used by Simple Network Management Protocol (SNMP) for GMPLS based
networks.
In particular in the context Wavelength Switching Optical Network
(WSON) two sets of information were defined: a general constrains set
(reusable by other technologies) and a WSON specific set. This
document defines a MIB module for supporting GMPLS WSON specific
information.

Internet-Draft GMPLS WSON MIB July 2012
1. Introduction
This memo defines a portion of the Management Information Base (MIB)
used by Simple Network Management Protocol (SNMP) in GMPLS networks.
Extentions to current GMPLS to support Wavelength Switched Optical
Networks (WSON) [RFC6163] include new objects with specific protocol
extentions. Some information where selected as a generic constrains
since they could be easily apply to other technologies than WSON. As
such this [I-D.ietf-ccamp-gmpls-general-constraints-ospf-te] OSPF-TE
was proposed and those information will be managed through a
separated MIB [ref required].
In case of WSON some technology specific information are required and
defined through [I-D.ietf-ccamp-rwa-info] and
[I-D.ietf-ccamp-wson-signal-compatibility-ospf]. This MIB module
will defines objects related to WSON specific informaton.
[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
This MIB module should be used in conjunction with
[I-D.ietf-ccamp-gmpls-ted-mib] since it only defineds additional
parmaters to GMPLS TED MIB.
5. Structure of the MIB Module

5.1.4. tedWsonResourcePoolState
5.1.5. tedWsonBlockSharedAccessWavelengthAvailability
6. Relationship to Other MIB Modules

6.2. MIB modules required for IMPORTS
7. Definitions
[TEMPLATE TODO]: put your valid MIB module here.
A list of tools that can help automate the process of
checking MIB definitions can be found at
http://www.ops.ietf.org/mib-review-tools.html
8. 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:
Galimberti, et al. Expires January 7, 2013 [Page 4]
Internet-Draft GMPLS WSON MIB July 2012
o
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.
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"
Galimberti, et al. Expires January 7, 2013 [Page 5]
Internet-Draft GMPLS WSON MIB July 2012
(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.
