Hierarchical policing is a form of two-color policing that applies different policing actions
based on whether the packets are classified for expedited forwarding (EF) or for a lower
priority. You apply a hierarchical policer to ingress Layer 2 traffic to allows bursts of EF
traffic for short period and bursts of non-EF traffic for short periods, with EF traffic always
taking precedence over non-EF traffic.
percentage —Traffic rate as a percentage of either the physical interface media rate or
the logical interface configured shaping rate. You can configure a shaping rate on a
logical interface by using class-of-service statement.
NOTE: You cannot rate-limit based on bandwidth percentage for tunnel or
software interfaces. The bandwidth percentage policer also cannot be used
for forwarding table filters. Bandwidth percentage policers can only be used
for interface-specific filters. Bandwidth percentage policers applied on an
aggregated Ethernet bundle or an aggregated SONET bundle do match the
effective bandwidth and burst-size to user-configured values by default and
do not require shared-bandwidth-policer
Range: 0 through 100
Default: None.
