Other filter attributes
There are three other attributes to each filter:
■ The filter’s order (i.e., priority) in the filter set
■ Whether the filter is currently active
■ Whether the filter is set to pass (forward) packets or to block (discard) packets
Putting the parts together
When you display a filter set, its filters are displayed as rows in a table:
The table’s columns correspond to each filter’s attributes:
#: The filter’s priority in the set. Filter number 1, with the highest priority, is first in the table.
Source IP Addr: The packet source IP address to match.
Dest IP Addr: The packet destination IP address to match.
