The documentation doesn't seem to indicate that "policer will by
default be shared among multiple interfaces" is the case, unless EX is
different from mainline in it's implementation of a long-standing knob.
When you configure the filter-specific statement, a single policer set
is created for the entire filter. All traffic matching the terms of
the firewall filter with the action policer goes through that single
policer. The default is a term-specific policer in which a single
policer set is created for each term within the filter. All traffic
matching the terms of the firewall filter with the action policer goes
through the part of the policer that is specific to that term.
So this knob just widens the scope from one term to the whole filter
so that you can police multiple terms/types of traffic in one
aggregate token bucket, and has nothing to do with sharing policers
amongst multiple interfaces.
