Using the CLI to Manage Message Filters
Activating and Deactivating a Message Filter
A given message filter is either active or inactive and it is also either valid or invalid. A message filter
is only used for processing if it is both active and valid. You change an existing filter from active to
inactive (and back again) via the CLI. A filter is invalid if it refers to a listener or interface which does
not exist (or has been removed).

Note
You can determine if a filter is inactive by its syntax; AsyncOS changes the colon after the filter name
to an exclamation point for inactive filters. If you use this syntax when entering or importing a filter,
AsyncOS marks the filter as inactive.

the

filter -> set
subcommand. Note that when the details of the filter are shown, the colon has been
changed to an exclamation point (and is bold in the following example).
