Dual-Homed Configuration Examples
The following sections show examples of dual-homed configurations.
You can use any of these configurations to dual home a MAP model that
has two Ethernet ports. MAP models with one Ethernet port support only
the dual-homing configuration in “Dual-Homed Distributed Connections
to WX Switches on One MAP Port” on page 188.

Dual-Homed Direct Connections to a Single WX
Figure 9 shows an
example of a dual-homed direct connection to one WX switch. In this
configuration, if the MAP’s active data link with the WX switch fails, the
MAP detects the link failure and restarts using the other link on the same
switch.
