In-Band Management and Out-of-Band Management

Cisco Fabric Manager requires an out-of-band (Ethernet) connection to at least one Cisco MDS 9000
Family switch. You need either mgmt0 or IP over Fibre Channel (IPFC) to manage the fabric.

MGMT0

The interface referred to as the out-of-band management connection is a 10/100 Mbps Ethernet interface
on the supervisor module, labeled mgmt0. The mgmt0 interface can be connected to a management
network to access the switch through IP over Ethernet. You must connect to at least one Cisco MDS 9000
Family switch in the fabric, through its Ethernet management port. You can then use this connection to
manage the other switches using in-band (Fibre Channel) connectivity. Otherwise, you need to connect
the mgmt0 port on each switch to your Ethernet network.
Each supervisor module has its own Ethernet connection; however, the two Ethernet connections in a
redundant supervisor system operate in active or standby mode. The active supervisor module also hosts
the active mgmt0 connection. When a failover event occurs to the standby supervisor module, the IP
address and media access control (MAC) address of the active Ethernet connection are moved to the
standby Ethernet connection.

IPFC

You can also manage switches on a Fibre Channel network using an in-band IP connection. The Cisco
MDS 9000 Family supports RFC 2625 IP over Fibre Channel, which defines an encapsulation method
to transport IP over a Fibre Channel network.
IPFC encapsulates IP packets into Fibre Channel frames so that management information can cross the
Fibre Channel network without requiring a dedicated Ethernet connection to each switch. IP addresses
are resolved to the Fibre Channel address through Address Resolution Protocol (ARP). This feature
allows you to build a completely in-band management solution.

Data management provides tools for ensuring the integrity, availability, and performance of data.
Data management services include redundant array of independent disks (RAID) schemes, data
replication practices, backup or recovery requirements, and data migration. Data management
capabilities are provided by third-party tools.
Application management provides tools for managing the overall system consisting of devices,
fabric, resources, and data from the application. Application management integrates all these
components with the applications that use the storage network. Application management
capabilities are provided by third-party tools.
