Table 30: Resource Consumption - Juniper POLICY MANAGEMENT - CONFIGURATION GUIDE V11.1.X Configuration Manual

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 179.

Table 30: Resource Consumption

Interface Attachment Resources Overview
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 information about supported line modules. See E120 and E320 Module
Guide, Appendix A, IOA Protocol Support for information about the modules that
support BGP.
On ASIC-based line modules (OC48/STM16, GE-2, and GE-HDE line modules),
you can have a maximum of 8191 IP policy attachments and 8191 layer 2 policy
attachments for ingress policies per forwarding controller, and 8191 IP policy
attachments and 8191 layer 2 policy attachments for egress policies per
forwarding controller.
