1. 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].
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].

2. 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.
Venkatesen Standards Track [Page 3]RFC 6173 iFCP MIB March 2011
3. 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 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.

DESCRIPTION
"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)."

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