In this example, the policy list named polWestford5 references four classifier lists with
a combination of software and hardware classifiers.

For a given line module, the policy list named polWestford5 consumes a total of one
FPGA hardware classifier resource and two software classifier resources, as indicated in
Table 30 on page 170.

JunosE Software allocates interface attachment resources when policies are attached
to interfaces—when you attach a policy to an interface, the policy consumes one of the
interface's attachment resources. Each interface has two attachment resource pools. IP
and IPv6 policy attachments are allocated from the interface's IP attachment resource
pool; all other attachments are allocated from the interface's layer 2 attachment resource
pool.
The type of line module determines the number of policies attachments supported by
interfaces. See ERX Module Guide, Appendix A, Module Protocol Support for more
