Configuring Traffic Filters and Protocol Prioritization

1-12

Actions

The ﬁlter action determines what happens to packets that match a ﬁlter criterion’s

ranges. Trafﬁc ﬁlter actions are mutually exclusive, except the Log action.

In addition to the common trafﬁc ﬁlter actions described in this section, there are

protocol-speciﬁc actions, described in Chapter 3.

Filtering Actions

You can apply the following actions to any trafﬁc ﬁlter:

• Accept — The router processes any packet that matches the ﬁlter criteria and

ranges.

• Drop — The router does not route any packet that matches the ﬁlter criteria

and ranges.

• Log — For every packet that matches the ﬁlter criteria and ranges, the router

sends an entry to the system Events log. You can specify the Log action in

combination with other actions.

Prioritizing Actions

Outbound trafﬁc ﬁlters for WAN protocols also include the following actions for

directing matching trafﬁc into circuit-based protocol priority queues:

• High — Packets that match the ﬁlter criteria and ranges are processed in the

high queue.

• Low — Packets that match the ﬁlter criteria and ranges are processed in the

low queue.

• Length — For packets that match the ﬁlter criteria, the packet length

determines the priority queue into which it is placed.

Note: Specify the Log action only to record abnormal events; otherwise, the

Events log will ﬁll up with ﬁltering messages, leaving no room for critical log

messages.

Note: Site Manager does not support protocol prioritization on outbound LAN

trafﬁc ﬁlters.
