Configuring SNAX/XF Passthrough
You should have performed Tasks 1 through 3 of Configuration Quick Start on
page 1-1.
Figure 5-2
on page 5-4 shows an example of SNAX/XF passthrough. The SNAX/XF
SCF configuration, shown alongside, configures a secondary line that has three
passthrough LUs configured for different types of passthrough:

$SNAS1.#PLU1 is configured for dynamic passthrough.

$SNAS1.#PLU2 is configured for associated passthrough.
