Switch A
Switch D
In Figure
C has the IPv4 address 1.12.11.3, and switch D has the IPv4 address 1.12.11.4. Switch A is the gateway
switch with the Ethernet connection. The NMS uses the IPv4 address 1.1.1.10 to connect to the gateway
switch. Frames forwarded to any switch in the overlaid VSAN 1 are routed through the gateway switch.
Configuring the gateway switch's IPv4 address (1.12.11.1) in the other switches enable the gateway
switch to forward the frame to the intended destination. Similarly, if a non-gateway switch in the VSAN
forwards a frame to the Ethernet, the frame is routed through the gateway switch.
When forwarding is disabled (default), IP frames are not sent from one interface to another. In these
cases, the software performs local IP routing between two switches using the in-band option for Fibre
Channel traffic and the mgmt0 option for Ethernet traffic.
When a VSAN is created, a VSAN interface is not created automatically. You need to specifically create
the interface.
To configure default networks using IPv4 addresses, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# ip default-network 190.10.1.0
switch(config)# ip route 10.0.0.0 255.0.0.0 131.108.3.4
switch(config)# ip default-network 10.0.0.0

IPFC

IPFC provides IP forwarding on in-band switch management over a Fibre Channel interface (rather than
out-of-band using the Gigabit Ethernet mgmt 0 interface). You can be use IPFC to specify that 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.
Once the VSAN interface is created, you can specify the IP address for that VSAN. You can assign an
IPv4 address or an IPv6 address.

Purpose
Enters configuration mode.
Configures the IPv4 address for the
default network (190.10.1.0).
Defines a static route to network
10.0.0.0 as the static default route.
