16.2.1 Assured Forwarding (AF) PHB for DiffServ
Assured Forwarding (AF) behavior is defined in RFC 2597. The AF behavior group defines four AF
classes. Inside each class, packets are given a high, medium or low drop precedence. The drop
precedence determines the probability that routers in the network will drop packets when
congestion occurs. If congestion occurs between classes, the traffic in the higher class (smaller
numbered class) is generally given priority. Combining the classes and drop precedence produces
[no] policy controll-virtual-server-rules
activate
Gives policy routes priority over NAT virtual server rules (1-1 SNAT).
Use the no command to give NAT virtual server rules priority over
policy routes.
[no] policy6 override-direct-route
activate
Has the ZyWALL / USG forward IPv6 packets that match a policy route
according to the policy route instead of sending the packets to a
directly connected network. Use the no command to disable it.
show bwm activation Displays whether or not the global setting for bandwidth management
on the ZyWALL / USG is enabled.
show bwm-usage < [policy-route
policy_number] | [interface
interface_name]
Displays the specified policy route or interface’s bandwidth allotment,
current bandwidth usage, and bandwidth usage statistics.
show policy-route [policy_number] Displays all or specified policy route settings.
show policy-route begin <1..200> end
<1..200>
Displays the specified range of policy route settings.
show policy-route conn-check Displays the policy route for the connection check.
show policy-route conn-check
[policy_number]
Displays the specified policy route for the connection check.
show policy-route conn-check status
[policy_number]
Displays the connection check status for the specified policy route.
show policy-route controll-ipsec-dynamic-
rules
Displays whether the ZyWALL / USG checks policy routes first before
IPSec dynamic rules.
show policy-route override-direct-route Displays whether or not the ZyWALL / USG forwards packets that
match a policy route according to the policy route instead of sending
the packets to a directly connected network.
show policy-route controll-virtual-server-
rules
Displays whether or not policy routes have priority over NAT virtual
server rules (1-1 SNAT).
show policy-route6 override-direct-route Displays whether or not the ZyWALL / USG forwards IPv6 packets that
match a policy route according to the policy route instead of sending
the packets to a directly connected network.
show policy-route rule_count Displays the number of policy routes that have been configured on the
ZyWALL / USG.
show policy-route underlayer-rules Displays all policy route rule details for advanced debugging.
show policy-route6 [policy_number] Displays all or specified IPv6 policy route settings.
show policy-route6 begin <1..200> end
<1..200>
Displays the specified range of IPv6 policy route settings.
show policy-route6 controll-ipsec-dynamic-
rules
Displays whether the ZyWALL / USG checks IPv6 policy routes first
before IPSec dynamic rules.
show policy-route6 rule_count Displays the number of IPv6 policy routes that have been configured
on the ZyWALL / USG.
