Table 4-6. Filters Options (1 of 2)
IP Filters (IP Filter Table) A-G-A
The IP Filter Table screen displays the following information:
Item # – Enter a value from 1–8 to add, delete, or modify individual filter entries.
Filter Name – Name of the IP filter. (This field is read-only.)
# of Rules – Number of rules in the IP filter. (This field is read-only.)
Def filter action – Forward/discard. Default filter action. (This field is read-only.)
VNID – Interface and VNID to which the filter belongs. (This field is read-only.)
Port – Port to which the filter belongs: s1c–s1f. (This field is read-only.)
Filter status – Active/Inactive (Default = Inactive). (This field is read-only.)
Direction – Inbound/Outbound. (This field is read-only.)
On the bottom of this screen, at the
Item Number (0 to Add, # to Edit, –# to Delete) prompt:
H Select 0 (zero) to add a new filter.
H Select # ( n) to edit existing filters. Example: Enter 3 to add Filter #3.
H Select -# (– n) to delete a filter. Example: Enter –6 to delete Filter #6.
The Add or Edit selection takes you to the IP Filter Configuration screen. When you exit
that screen, you return to the IP Filters screen.
NOTE: Deleting the filter deletes all the rules associated with that filter.
IP Filters (IP Filter Configuration screen) A-G-A
Allows you to build multiple rules for an IP filter. A filter consists of a set of rules applied
to a specific interface to indicate whether a packet received or sent out of that interface
is forwarded or discarded. You can add, edit, or delete filter rules within a named set.
A filter works by successively applying the rules to the information obtained from the
packet header until a match is found. The filter then performs the action specified by the
rule on that packet, which forwards or discards the packet. If all the rules are searched
and no match is found, the configured default filter action is executed.
Host rules have higher precedence than network rules. Rules apply to the
source/destination IP address, source/destination port number, and traffic types, such
as TCP/UDP/ICMP. TCP/UDP/ICMP traffic is forwarded or discarded based on the
conditions specified in the rule, including source and/or destination address and source
and/or destination port number. You can have up to 33 rules per filter. Each rule reduces
the packet throughput of the DSL card.
There can be 8 filters per DSL card with a maximum of two filters per DSL port, one
inbound filter and one outbound filter. The same filter can be applied as an inbound filter
and an outbound filter. Filters are configured on the port card and the processing takes
place on the endpoint.
NOTE: Once your rules have been configured, you can then bind and activate the
filter on the DSL interface using the
