Service Filters in ACX Series
When you apply a service set to the traffic at an inline services interface, you can optionally
use service filters to refine the target of the set of services and also to process traffic.
Service filters enable you to manipulate traffic by performing packet filtering to a defined
set of services on an inline services interface before the traffic is delivered to its destination.
In ACX Series routers, you can apply a service filter to traffic before packets are accepted
for input service processing.
NOTE: In ACX Series routers, the service-set filters are implemented using
ternary content addressable memory (TCAM) space. The allocated TCAM
space is shared by the bridge family filter. The same space is shared by the
NNI-Address-Overload-Reverse filter (for each service set that is configured
with address overloading, the internal filters are configured for the given
overloaded IP address and the port range to redirect the matched reverse-nat
(public to private) traffic to the service). From a scaling perspective, the
allocated 124 hardware TCAM entries are shared by these features and the
allocation of TCAM entries works on a first-come-first-serve basis mode.
