Abstract
The iFCP protocol provides Fibre Channel fabric functionality on an
IP network in which TCP/IP switching and routing elements replace
Fibre Channel components. The iFCP protocol is used between iFCP
Gateways. This draft provides a mechanism to monitor and control
iFCP Gateway instances, and their associated sessions, using SNMP.
This memo is a product of the IP Storage (IPS) working group within
the Internet Engineering Task Force. Comments are solicited and
should be addressed to the working group's mailing list at
ips@ece.cmu.edu and/or the authors.

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].
2. Introduction
The iFCP protocol can be used by FC to IP based storage gateways
for FCP storage interconnects. Figure 1 provides an example
interconnect between iFCP gateways.

The iFCP MIB is designed to allow SNMP to be used to monitor and
manage local iFCP gateway instances, including the configuration of
iFCP sessions between gateways.
3. Technical Description
Gibbons Expires September 2003 3
Internet Draft iFCP MIB March 2003
The MIB 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. Other standard MIBs, such as the Fibre
Management MIB [FCMGT01], the Interfaces Group MIB [RFC2863] and
MIB II [RFC1213] 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 are using one of the local iFCP gateway instances.
This section allows the management of specific iFCP parameters.
The iFCP session statistics section provides statistical
information on the iFCP sessions that are using 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 standard and low-
capacity (counter32) methods.

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
Gibbons Expires September 2003 20
Internet Draft iFCP MIB March 2003
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. These are the tables and objects
and their sensitivity/vulnerability:
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.
