Internet Draft FCIP MIB October 2004 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 FCIP Entity is fully described in [FCIP] 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 | | | | +-----------+ +-----------+ | | |FCIP Entity| |FCIP Entity| | | | | | | | | | | | | | | +--+--+--+--+ +--+--+--+--+ | | | | | | | | | | | | | | | | | | FCIP Links FCIP Links | | | +------------------------------------------+ The FCIP device provides IP-based interconnection model to interconnect 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. FCIP MIB Expires April 2005 [Page 3]
Internet Draft FCIP MIB October 2004 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 standalone box or as part of a FC fabric element. Each FCIP Entity managed by this MIB is referred to as a 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 a 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 in conjunction with other protocols, such as 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 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 of 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. FCIP MIB Expires April 2005 [Page 4]
Internet Draft FCIP MIB October 2004 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 MIBs applicable to FCIP devices have not been included in this MIB. The following lists all applicable MIB modules/objects that should be present with FCIP-MGMT-MIB. 3.1 Relationship to the 'TCP' group of MIB-II This group is mandatory for all systems which implement TCP. Objects relevant to TCP must be obtained from this group. 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 "ftp://ftp.isi.edu/mib/iana.mib/ianaiftype.mib". These are the only ifIndex values of relevance to an FCIP Entity because FCIP runs on top of TCP/IP. When an FCIP entity has data to transmit to a peer FCIP entity, it gives it to TCP, and TCP formats the data into segments and gives them to IP; IP puts the data into datagrams which it sends on whatever one or more physical interfaces IP has available. Therefore, only IP, not an FCIP Entity, has knowledge of the ifIndex values for physical interfaces. 3.3 Relationship to the Fibre Channel Management MIB The Fibre Channel Management MIB [FCMGMT] 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) FCIP MIB Expires April 2005 [Page 5]
Internet Draft FCIP MIB October 2004 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 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'. 4. Changes from draft-ietf-ips-fcip-mib-05.txt o Added ASCII picture depicting FCIP Device/Entity/Link. o Added 'fcipLink' value and IANA URL for ifType MIB. FCIP MIB Expires April 2005 [Page 6]
Internet Draft FCIP MIB October 2004 o Clarification of Static and Dynamic table conflict resolution. o Syntax for fcipEntityName and fcipDiscoveryDomainName changed from DisplayString to SnmpAdminString. o Several boilerplate and typo corrections. o Description of fcipEntityRowStatus, fcipLinkStatus and fcipStaticRouteStatus updated to describe behavior when status is set to active(1) and destroy(6).

Internet Draft FCIP MIB October 2004 6. 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 SAN. 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 fcipLinkRemFcipEntityAddress fcipDynamicRouteTable fcipStaticRouteTable fcipDiscoveryDomainTable 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.
