Firewall
The fall-back policy will be used for traffic that is not matched by any other policy. If there
is no default policy associated with this binding, packets that do not match any policy
rules will be dropped. If the policy is not a fall-back policy, you must configure at least one
rule:
i. Change to the rule node of the configuration:
(config firewall qos 2 policy 0)> rule
(config firewall qos 2 policy 0 rule)>
ii. Add a rule:
(config firewall qos 2 policy 0 rule)> add end
(config firewall qos 2 policy 0 rule 0)>
New QoS binding policy rules are enabled by default. To disable:
(config firewall qos 2 policy 0 rule 0)> enable false
(config firewall qos 2 policy 0 rule 0)>
iii. (Optional) Set a label for the new binding policy rule:
(config firewall qos 2 policy 0 rule 0)> label my_binding_policy_
rule
(config firewall qos 2 policy 0 rule 0)>
iv. Set the value of the Type of Service (ToS) packet header that defines packet priority. If
unspecified, this field is ignored.
(config firewall qos 2 policy 0 rule 0)> tos value
(config firewall qos 2 policy 0 rule 0)>
where value is a hexadecimal number. See
a list of common TOS values.
v. Set the IP protocol matching criteria for this rule:
(config firewall qos 2 policy 0 rule 0)> protocol value
(config firewall qos 2 policy 0 rule 0)>
where value is one of tcp, udp, or any.
vi. Set the source port to define a source traffic matching criteria:
(config firewall qos 2 policy 0 rule 0)> srcport value
(config firewall qos 2 policy 0 rule 0)>
where value is the IP port number, a range of port numbers using the format IP_port-
IP_port, or any.
vii. Set the destination port to define a destination matching criteria:
(config firewall qos 2 policy 0 rule 0)> dstport value
(config firewall qos 2 policy 0 rule 0)>
