Field Description
Enable/Disable You can click the Enable and Disable radio buttons to
activate/deactivate the service. Although each rule
can be independently enabled and disabled, no rules
will be effective unless the Enable radio button is
selected here.
Default Action Your selection in the Default Action drop-down list
determines the action to be taken on all packets that
do not match a bridge filter rule. The available options
are:
o Accept: All packets are accepted on all interfaces
— except those specifically denied by a bridge
filter rule. (Packets may still be denied due to
firewall or IP filter restrictions.)
o Deny: All packets are denied on all interfaces —
except those specifically accepted by a bridge
filter rule.
Do not select CallMgt option — it is for manufacturer
use only.
Adding Bridge Filter Rules
Adding and enabling a new bridge filter rule is a multi-step process:
f First, you add the rule, which defines general information
such as the rule number, the direction of traffic it applies to,
and the action to be taken when a match is detected.
f Next, you add one or more subrules, which specify the
specific criteria that the bits in the packet must meet. A
packet must match the rule criteria and all criteria in its
subrules in order for the rule action to taken.
f Finally, you enable the rule and any subrules that you want
to be in effect, and then enable the bridge filtering service.
Follow this process to add a rule, then proceed to the next set of
steps to add subrules:
