Configuring IP Services
Cisco MDS 9000 Family switches can route IP traffic between Ethernet and Fibre Channel interfaces.
The IP static routing feature is used to route traffic between VSANs. To do so, each VSAN must be in a
different IP subnetwork. Each Cisco MDS 9000 Family switch provides the following services for
network management systems (NMSs):
• IP forwarding on the out-of-band Ethernet interface (mgmt0) on the front panel of the supervisor
modules.
• IP forwarding or in-band Fibre Channel interface using the IP over Fibre Channel (IPFC)
function—IPFC specifies how IP frames can be transported over Fibre Channel using encapsulation
techniques. IP frames are encapsulated into Fibre Channel frames so NMS information can cross the
Fibre Channel network without using an overlay Ethernet network.
• IP routing (default routing and static routing)—If your configuration does not need an external
router, you can configure a default route using static routing.
Switches are compliant with RFC 2338 standards for Virtual Router Redundancy Protocol (VRRP)
features. VRRP is a restartable application that provides a redundant, alternate path to the gateway
switch.
Note For information about configuring IPv6, see Chapter 54, “Configuring IPv6 for Gigabit Ethernet
Interfaces.”
