BIOS Configuration Overview
49
• SCTP
• Linux Bonding
• Solaris Multipathing.
These protocols allow for detection of a working path to an upstream resource such as a router,
and then move a virtual IP address from a failed interface to a working interface.
Figure 3-11 illustrates this configuration. Two CPC5565 blades are connected via Fabric-A to
VLAN-1, which is connected to Router-A. These blades are also connected via Fabric-B to
VLAN-2, which is connected to Router-B. The Inter-Switch Link (ISL) between the fabrics is
disabled. For IP redundancy, the CPC5565 blades could use the Linux Bonding driver and
monitor the path to each router with ARPs and 'plumb' a Virtual IP Address onto the active
interface.

A similar H/A configuration can be achieved with this configuration using SCTP or Multipathing.
This technique can be used with or without tagged interfaces. To allow for tagged interfaces,
you must enable Port-Mode VLANs in the BIOS (see
“Port VLAN Mode,” on page 44 ).
Untagged interfaces can be used with the default Dot1Q-Mode (see “802.1Q VLAN Mode,” on
page 43 ). Since there is no potential for a loop to form, Spanning Tree may be disabled on the
ports connected to the CPC5565.
