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.

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.

      Figure 1: Interconnect between iFCP Gateways

The iFCP MIB module is designed to allow a network management protocol such as SNMP to be used to monitor and manage local iFCP gateway instances, including the configuration of iFCP sessions between gateways.

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.

Differences from RFC 4369

As explained in RFC6172, the iFCP address translation mode is deprecated. This document obsoletes the iFCP MIB module RFC4369 for this change.

"Each entry contains information about one iFCP session consisting

of a pair of N_PORTs joined by a single TCP/IP connection.  This
table's INDEX includes ifcpLclGtwyInstIndex, which identifies the
local iFCP gateway instance that created the session for the
entry.

Soon after an entry is created in this table for an iFCP session, it
will correspond to an entry in the tcpConnectionTable of the TCP-MIB
(RFC 4022).  The corresponding entry might represent a preexisting
TCP connection, or it might be a newly created entry.  (Note that if
IPv4 is being used, an entry in RFC 2012's tcpConnTable may also
correspond.)  The values of ifcpSessionLclPrtlAddrType and
ifcpSessionRmtPrtlIfAddrType in this table and the values of
tcpConnectionLocalAddressType and tcpConnectionRemAddressType used
as INDEX values for the corresponding entry in the
tcpConnectionTable should be the same; this makes it simpler to
locate a session's TCP connection in the TCP-MIB.  (Of course, all
four values need to be 'ipv4' if there's a corresponding entry in
the tcpConnTable.)

If an entry is created in this table for a session, prior to
knowing which local and/or remote port numbers will be used for
the TCP connection, then ifcpSessionLclPrtlTcpPort and/or
ifcpSessionRmtPrtlTcpPort have the value zero until such time as
they can be updated to the port numbers (to be) used for the
connection.  (Thus, a port value of zero should not be used to
locate a session's TCP connection in the TCP-MIB.)

When the TCP connection terminates, the entry in the
tcpConnectionTable and the entry in this table both get deleted
(and, if applicable, so does the entry in the tcpConnTable)."

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
    ifcpSessionAttributesTable

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.

IANA Considerations

The MIB module in this document uses the following IANA-assigned OBJECT IDENTIFIER value recorded in the SMI Numbers registry:
