The auto-created embedded filters can be viewed through CLI but cannot be modified and/or
deleted through filter policy CLI/SNMP. Operator can see the above embedded filters under show
filter context, including the details on the filters themselves, entries programmed, interface
association, statistics, etc.
The following picture depicts the H-OFS to service operator-configurable mapping example.

The router allows mixing H-OFS rules from one or more H-OFS instances in a single filter policy.
Co-existence of H-OFS rules in a single policy with CLI/SNMP programmed rules and/or BGP
flowspec programmed rules in a single line card filter policy is also supported. Note that for
mixing of the rules from multiple management entities, the controller should not program an entry
in its Flow Table that would match all traffic, as this would stop evaluation of the filter policy.
