Note:
Since each type of traffic uses two physical interfaces, use of a vPC is recommended if possible.
Otherwise, a regular PortChannel configuration should be used, but the two physical links need to connect to a
single upstream switch.
Network Connection Option 5 (Flexible Network)
With the addition of the flexible network option, users can now more flexibly deploy their VSBs on the Cisco Nexus
1100 Series. With this option, you do not need to specify which ports allow which types of traffic (management,
control, or data traffic). One of the main advantages of this option is that you can define a VSB to use a particular
interface. This approach enables a more specific level of traffic engineering for security purposes. For example, a
VSM VSB for production can use an interface connected to the production network, and another VSM VSB can be
created for the DMZ, which uses another interface connected to the DMZ network. Figure 13 shows two of the
possible options with the flexible network traffic flow options.

Network Connection Option 5
Note:
The options shown here are just two possible options; other options are possible that are a mix of the
combinations shown.
Another feature enhancement in the Cisco Nexus 1100 Series Version 4.2(1)SP1(4) release is the capability to
create a PortChannel with the LOM interfaces as well with the other four Gigabit Ethernet interfaces. This
enhancement can simplify the configuration for network connectivity, as shown in Figure 14.
