Modifying a Filter Policy
There are several ways to modify an existing filter policy. A filter policy can be modified
dynamically as part of subscriber management dynamic insertion/removal of filter policy entries
(see SROS Triple Play Guide for details). A filter policy can be modified indirectly by
configuration change to a match list the filter policy uses (as described earlier in this guide). In
addition, a filter policy can be directly edited as described below.
To access a specific IP (v4/v6), or MAC filter, you must specify the filter ID, or if defined, filter
name. Use the
no
form of the command to remove the command parameters or return the
parameter to the default setting.
Example :
config>filter>ip-filter# description "New IP filter info"
config>filter>ip-filter# entry 2 create
config>filter>ip-filter>entry$ description "new entry"
config>filter>ip-filter>entry# action drop
config>filter>ip-filter>entry# match dst-ip 10.10.10.104/32
config>filter>ip-filter>entry# exit
config>filter>ip-filter#
The following output displays the modified IP filter output:
A:ALA-7>config>filter# info
