INS Filters Window
This window appears when you choose Device >
INS Filters on the menu bar. Use it to:
- Create security filters that control traffic on selected interfaces
- Create QoS filters that give preferential service to selected packets on selected interfaces
- See detailed information about security and QoS filters
You can click here to launch the window.
Follow these steps:
- Select a device from
the Host Name list. The Interface column of the table will list the interfaces
on the device.
- Click in the row of an interface to select it.
Notes: - The first time you use this window, you see none
throughout the Security and QoS columns of the table, meaning that no security
or QoS filter is associated with the interfaces. When you create a filter, an
instance of none is replaced by a field set notation. A field set
is the fields of a Layer 2, Layer 3, or Layer 4 packet header against which a
filter is matched. For example, the notation ip-sa, ip-da is for a field
set that means "match the filter against the fields that contain the IP source
and destination addresses."
- An interface can have any number of filters
but only one field set for security and one for QoS. A device can have no more
than two security field sets and two QoS field sets.
- Take one of
the following actions:
- To create a filter for the interface
or to modify an existing filter, click Modify and use the Modify INS Filter
window.
- To see the detailed information underlying a field set, click
Details and use the INS Filter Details window.
- Click
OK to save work in other windows and to close this window.
