Traceconfig result The output will look similar to this one:
When a packet is received it will be checked against all the rules.
On the first line we see that the packet is checked against the
rule 17 in the chain
qos_default_labels
.
On the second line we see that
rule 17
aplies to all packets of the
ike
type.
Line three shows that the packet does not match the rule. (
-
expr serv ike)
Line four shows the next rule that will be checked. This is
rule 18
of the chain
qos_defqult_labels
.
Line five shows that this rule applies to all packets of the
icmp
type.
Line six and seven show that this rule applies to this packet. (
+
expr serv icmp)
Line eight shows that the rule matching has ended.
