Outbound Traffic Filter Criteria and Actions

Figure 4-2. Predeﬁned IP Outbound Filter Criteria

Specifying Criteria Common to IP and Data Link Headers

To conﬁgure outbound ﬁlters for criteria that are common to both IP and Data

Link headers (DSAP, SSAP, Protocol ID, DLCI, NLPID), create two ﬁlters: one

for IP and the other for the Data Link type. For example, if you want a ﬁlter rule

with a priority of High for all Frame Relay trafﬁc with DLCI 400, create ﬁlters for

both IP and Data Link using the DLCI criterion and a range of 400 to 400.

To conﬁgure a ﬁlter to apply to either the IP or Data Link header only, create only

one ﬁlter. To conﬁgure ﬁlters for IP-routed packets only, always select IP instead

of Data Link. If you create a ﬁlter under Data Link to identify an IP-routed packet

(for example, using the Ethertype ﬁeld and a value of 0x0800), the rule is never

triggered because the router code recognizes the IP packet and uses IP ﬁlter rules.
