Traffic Shaping, UPC, and Virtual Interface Configuration
Compatibilities
Configuration compatibility among the ATM Traffic Shaping, UPC Support,
and VI Support features is shown in Table C-10. In the table, Yes indicates
that the two features coinciding in the matrix can be configured in the same
interface, and No indicates that they cannot. See Figure C-1 for an illustra-
tion of this concept.
