1. Abstract

The goal of this document is to model and define management MIB for the 
FCIP device so that it can be part of an enterprise class storage 
network. The FCIP device is specified in the Internet-draft 
<draft-ietf-ips-fcovertcpip-02.txt> [1].
Since the FCIP device is one of the SAN fabric devices, the FCIP 
management 
MIB is defined such that it can extend the existing framework MIB, which 
is specified in <draft-ietf-ipfc-fcmgmt-int-mib-06.txt> [2], to model 
the new FCIP device under the existing overall FC management framework. 
This approach will enable the FCIP devices to integrate smoothly into 
the SAN integrated management environment for the enterprise customer.


2. Overview of FCIP-Device Based Interconnection Model 

Note that the FCIP-Device is fully described in [1] from functional 
point of view; whereas this section describes the FCIP-Device from 
management point of view.

The FCIP device is modeled as a "gateway" FC Connectivity Unit as the 
FCIP device acts as a gateway connection unit to bridge the FC onto the 
IP technology. 

The FCIP-devices provides IP-based interconnection model to interconnect 
the FC fabric elements. In this model, the FCIP-devices, along with 
their IP-network, provides a new FCIP transport network. The FC fabric 
elements (FC-FEs) will support the Logical FC Links in their overlay 
network that resides on this FCIP transport network.
 
This IP-based FCIP Interconnection Model supports the following 
topology:
-	The FCIP-based transport network is formed by 
interconnecting the FCIP-devices.
-	The peer FCIP-devices are interconnected by the Virtual-
Links. 
?	An FCIP-device establishes Virtual-Links with its 
peer FCIP devices. 
?	There will be only one Virtual-Link between two 
peer FCIP devices. 
-	A single Virtual-Link consists of multiple sets of TCP 
connections (known as the TCP Links in this document).
?	There could be one of set of TCP links for 
transmitting FC frames.
?	There could be another set of TCP links for 
transmitting control and priority messages.
-	An FCIP-device may have one or more FCIP-endpoints (known 
as the FCIP-ports in this document) facing the IP network.
?	One FCIP-port can be used to form one or more 
Virtual-Links.
-	An FCIP-device may have one or more B-ports or E-Ports 
facing the FC fabric side. 
?	These ports might connect one or more FC-FEs to the 
FCIP-device.
?	If the B-port is used to connect the neighboring 
FC-FE and FCIP_device, it establishes a bridge-
links between the FC-FE and FCIP-device. 
-	The FCIP-device can work as a stand-alone box or as part 
of a FC fabric element. 

The MIB specified in this document supports the above FCIP-devices, 
FCIP-based transport network, and FC overlay network under the existing 
overall FC management framework [2] by extending/augmenting the 
framework MIB [2].

Note that a Virtual Inter-Switch Link, as per [1], is a Logical FC Link 
between two E-ports. The association between the Virtual Inter-Switch 
Link (Virtual-Link) and the related Virtual-Links and Bridge-Links is as 
follows:
?	One Virtual Inter-Switch Link spans one Virtual-Link if both the 
FCIP-devices, through which this Virtual-Link passes through, 
operate in E-port mode.
?	One Virtual Inter-Switch Link spans one Virtual-Link and two 
Bridge-Links if both the FCIP-devices, through which this Virtual-
Link passes through, operate in B-port mode.
?	One Virtual Inter-Switch Link spans one Virtual-Link and one 
Bridge-Link if one FCIP-device operates in B-port mode and the 
other FCIP-Device operates in E-port mode.
