Abstract
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in TCP/IP-based internets.
In particular, it defines objects for managing Fibre Channel Over
TCP/IP (FCIP) entities, which are used to interconnect Fibre Channel
(FC) fabrics with IP networks.

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. Overview of FCIP Management Model
Note that the Fibre Channel Over TCP/IP (FCIP) Entity is fully
described in [RFC3821] from a functional point of view. A collection
of multiple instances of FCIP Entities and the corresponding FC
Entities, described in [FCBB2], within an SNMP Context is referred to
as an FCIP device here. This section describes FCIP from a
management point of view.
+------------------------------------------+
| FCIP Device |

+------------------------------------------+
The FCIP device provides an IP-based interconnection model for
interconnecting FC fabric elements. In this model, the FCIP devices
along with the IP network on which they are running provide a new
FCIP transport network.
This IP-based FCIP Interconnection Model supports the following
topology:
o The FCIP-based transport network is formed by interconnecting the
FCIP devices.
o Each FCIP device has one or more FCIP Entities or Instances.
o Peer FCIP Entities are connected by FCIP Links attached to
VE_ports/B_Access.
o Each FCIP Link Endpoint contains one or more Data Engines.
o The FCIP device can work as a stand-alone box or as part of a FC
fabric element.
Each FCIP Entity managed by this MIB is referred to as an FCIP
Instance. The MIB is broken up as follows:
2.1. FCIP Entity Instances Table
The FCIP Entity table contains information about this entity's
existing instances of FCIP entities.
2.2. FCIP Link Table
The FCIP link table contains information about this FCIP device's
existing FCIP links.
2.3. FCIP TCP Connection Table
The FCIP TCP Connection table contains information about existing TCP
connections. Each FCIP link within an FCIP entity contains one or
more TCP connections. The FCIP entity employs a Data Engine for each
TCP connection for handling FC frame encapsulation, de-encapsulation,
and transmission of FCIP frames on the connection.
2.4. FCIP Dynamic Route Table
The FCIP dynamic route table contains routing information that is
dynamically discovered by this FCIP device. The FCIP device may use
the SLPv2 protocol [RFC3822] in conjunction with other protocols,
such as Fabric Shortest Path First (FSPF), to dynamically discover
other FCIP entities and populate this table to map destination
domains to FCIP Links.
2.5. FCIP Static Route Table
The FCIP static route table contains routing information that is
statically configured into this FCIP device by the Network Admin. In
the absence of dynamic discovery of remote FCIP entities, the Network
Manager can configure remote domains and FCIP Entities that are
reachable by this device into this table.
At any point in time, both the static and dynamic routing tables can
be active. If a DID is present in both tables, information in the
static route table will take precedence over the entry in the dynamic
route table for the same DID.
2.6. FCIP Discovery Domain Table
The FCIP Discovery Domain Table maps this device's FCIP Entities into
FCIP Discovery Domains.
2.7. FCIP Link Error Table
The FCIP Link Errors Table contains counters that indicate error
conditions on an FCIP Link.
3. Relationship to Other MIBs
Objects accessible from other MIB modules applicable to FCIP devices
have not been included in this MIB module. The following subsections
list all applicable MIB modules that should be present with FCIP-
MGMT-MIB.
3.1. Relationship to the 'TCP' Group
This group is mandatory for all systems that implement TCP. Objects
relevant to TCP must be obtained from this group [RFC4022].
3.2. Relationship to the 'interfaces' MIB
The 'interfaces' group is defined as being mandatory for all systems
and contains information on an entity's interfaces. Each
logical/virtual interface created as an FCIP Link should be
represented as a row in the ifTable with a unique ifIndex value and a
value of ifType 'fcipLink' (224) for each such interface. For a
complete list of interface types, refer to the IANA registry at
"http://www.iana.org/assignments/smi-numbers". These are the only
ifIndex values of relevance to an FCIP Entity because FCIP runs on
top of TCP/IP.
FCIP runs over TCP. Thus, by definition, there is no ifTable
interface directly beneath it, and so ifStackLowerLayer is always 0.
For any protocol using FCIP (i.e., above FCIP), FCIP appears to be a
regular FC interface. As stated in [RFC4044], a regular "FC
interface will typically have no other ifTable rows stacked on top of
it", and thus, ifStackHigherLayer is typically zero.
3.3. Relationship to the Fibre Channel Management MIB
The Fibre Channel Management MIB [RFC4044] is assumed for FC
functionality managed objects.
3.4. Specific Interface Group MIB Objects
The following table provides specific implementation guidelines for
applying the objects defined in the Interfaces Group MIB to FCIP
Links. For those objects not listed here, refer to their generic
definitions in [RFC2863].
Object Guidelines
ifType 'fcipLink' (224)
ifSpeed The ifSpeed for the physical interface(s)
over which the FCIP Link runs.
ifPhysAddress There is no physical address corresponding
to an FCIP Link (only World Wide Name, WWN).
Reported as 0.
ifAdminStatus Write access is not required, and support
for 'testing' is not required.
ifOperStatus Support for 'testing' is not required.
The value 'dormant' has no meaning for
FCIP Links.
ifInOctets The number of octets of FCIP information
ifHCInOctets contained in received frames in TCP
streams, starting with FCIP header.
ifInUcastPkts The number of FCIP frames received
ifHCInUcastPkts on this FCIP Link.
ifOutOctets The number of octets of FCIP information
ifHCOutOctets contained in transmitted frames in TCP
streams, starting with FCIP header.
ifOutUcastPkts The number of FCIP frames transmitted
ifHCOutUcastPkts on this FCIP Link.
ifInMulticastPkts These counters are not incremented.
ifInBroadcastPkts
ifOutMulticastPkts
ifOutBroadcastPkts
ifHCInMulticastPkts
ifHCInBroadcastPkts
ifHCOutMulticastPkts
ifHCOutBroadcastPkts
ifLinkUpDownTrapEnable Default is 'disabled'.
ifPromiscuousMode This will be 'false'.
ifConnectorPresent This will be 'false'.

5. Security Considerations
There are a number of management objects defined in this MIB that
have 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. In particular, write access to
fcipDiscoveryDomainName and fcipEntityAddress can cause a loss of
reachability to portions of the Fibre Channel fabric, while write
access to fcipStaticRouteStatus can create incorrect routes to remote
devices.
There are a number of managed objects in this MIB that contain what
could be considered as sensitive information. In particular, the
objects which provide information on identification and network
topology:
fcipDeviceWWN, fcipEntityName, fcipEntityAddress,
fcipLinkLocalFcipEntityAddress, fcipLinkRemFcipEntityWWN,
and fcipLinkRemFcipEntityAddress
-- information on identification;
fcipDiscoveryDomainName
-- information on discovery domains;
fcipDynamicRouteLinkIndex
-- information on dynamic routes;
fcipStaticRouteLinkIndex and fcipStaticRouteStatus
-- information on static routes
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.
6. IANA Considerations
The IANA has assigned a MIB OID assignment under the transmission
branch. Specifically, { transmission 224 } for fcipMIB since this
MIB contains the media-specific definitions that correspond to the
ifType value of fcipLink(224).
