Appendix A: System Maximums
Policy and QoS Maximums
Table 5 lists policy and QoS maximums for the ERX routers. The following notes
are referred to in Table 5:
1. The OC48 line module supports only 131,071 entries. The GE-2 and GE-HDE
line modules support only 65,535 entries.
2. For line modules other than the GE-2, GE-HDE, and OC48/STM16 line modules,
the router supports two sizes of policies: 8127 policies, each with a maximum
of 32 classifiers, and 16,255 policies, each with a maximum of 16 classifiers. A
combination of the two sizes of policies is also supported, in which case the
total number of policies is between 8127 and 16,255, depending on the actual
configuration.
3. The GE-2, GE-HDE, and OC48/STM16 line modules support CAM classifiers
instead of hardware policy assignments. For most configurations, each
classifier entry in a policy consumes one CAM entry. However, a policy that has
only the default classifier consumes no CAM resources. Policies that use CAM
hardware classifiers consume one interface attachment resource, regardless of
the number of classifier entries in a policy.
