The Internet-Standard Management Framework   For a detailed overview of the documents that describe the current   Internet-Standard Management Framework, please refer tosection 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].   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 [RFC2119].Venkatesen                   Standards Track                    [Page 2]

RFC 6173                        iFCP MIB                      March 20112.  Introduction   iFCP (RFC 4172 [RFC4172]) provides Fibre Channel fabric functionality   on an IP network in which TCP/IP switching and routing elements   replace Fibre Channel components.  iFCP is used between iFCP   gateways.  This protocol can be used by FC-to-IP-based storage   gateways for Fibre Channel Protocol (FCP) storage interconnects.   Figure 1 provides an example of an interconnect between iFCP   gateways.

RFC 6173                        iFCP MIB                      March 20113.  Technical Description   The iFCP MIB module is divided into sections for iFCP local gateway   instance management, iFCP session management, and iFCP session   statistics.   The section for iFCP gateway management provides default settings and   information about each local instance.  A single management entity   can monitor multiple local gateway instances.  Each local gateway is   conceptually an independent gateway that has both Fibre Channel and   IP interfaces.  The default IP Time Out Value (IP_TOV) is   configurable for each gateway.  Other standard MIBs, such as the   Fibre Management MIB [RFC4044] or Interfaces Group MIB [RFC2863], can   be used to manage non-iFCP-specific gateway parameters.  The local   gateway instance section provides iFCP-specific information as well   as optional links to other standard management MIBs.   The iFCP session management section provides information on iFCP   sessions that use one of the local iFCP gateway instances.  This   section allows the management of specific iFCP parameters, including   changing the IP_TOV from the default setting of the gateway.   The iFCP session statistics section provides statistical information   on the iFCP sessions that use one of the local iFCP gateways.  These   tables augment the session management table.  Additional statistical   information for an iFCP gateway or session, that is not iFCP-   specific, can be obtained using other standard MIBs.  The iFCP   statistics are provided in both high-capacity (Counter64) and low-   capacity (Counter32) methods.   The following MIB module imports from SNMPv2-SMI [RFC2578], SNMPv2-TC   [RFC2579], SNMPv2-CONF [RFC2580], HCNUM-TC [RFC2856], IF-MIB   [RFC2863], SNMP-FRAMEWORK-MIB [RFC3411], INET-ADDRESS-MIB [RFC4001],   FC-MGMT-MIB [RFC4044], ENTITY-MIB (v3) [RFC4133], and RMON2-MIB   [RFC4502].4.  Differences fromRFC 4369   As explained in [RFC6172], the iFCP address translation mode is   deprecated.  This document obsoletes the iFCP MIB module [RFC4369]   for this change.Venkatesen                   Standards Track                    [Page 4]

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.   Changing the following object values, with a MAX-ACCESS of read-   write, may cause disruption in storage traffic:        ifcpLclGtwyInstAddrTransMode        ifcpLclGtwyInstFcBrdcstSupport        ifcpLclGtwyInstDefaultIpTOV        ifcpLclGtwyInstDefaultLTInterval        ifcpSessionIpTOV   Changing the following object value, with a MAX-ACCESS of read-write,   may cause a user to lose track of the iFCP gateway:        ifcpLclGtwyInstDescr   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.   The following object tables provide information about storage traffic   sessions, and can indicate to a user who is communicating and   exchanging storage data:        ifcpLclGtwyInstTable        ifcpSessionAttributesTableVenkatesen                   Standards Track                   [Page 28]

RFC 6173                        iFCP MIB                      March 2011   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.7.
