7-12 Reference Guide
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:
+-#---Source IP Addr---Dest IP Addr----Proto-Src.Port-D.Port--On?-Fwd-+
| 1 192.211.211.17 0.0.0.0 TCP 0 23 Yes No |
| |
| |
| |
| |
+--------------------------------------------------------------------+
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.
Proto: The protocol to match. This can be entered as a number (see
the table below) or as TCP or UDP if using those protocols.
Protocol Number to use Full name
N/A 0 Ignores protocol type
ICMP 1 Internet Control Message Protocol
TCP 6 Transmission Control Protocol
UDP 17 User Datagram Protocol
