Network Requirements
- There is authentication server (AAA Server), video server and one terminal device (PC) in the network.
- Configure the SP+WRR function. When the traffic of the egress port is congested, first ensure that the traffic of the authentication server all can pass and the terminal traffic and video traffic can pass by the proportion of 1:2.

Configuration Steps
Step 1: Configure the link type of the VLAN and port on Device.
#Create VLAN2.
Device#configure terminal
Device(config)#vlan 2
Device(config-vlan2)#exit
|
#Configure the link type of port gigabitethernet0/1 as Access and permit the services of VLAN2 to pass.
Device(config)#interface gigabitethernet 0/1
Device(config-if-gigabitethernet0/1)#switchport mode access
Device(config-if-gigabitethernet0/1)#switchport access vlan 2
|
#Configure the link type of port gigabitethernet0/2 as Trunk and permit the services of VLAN2 to pass.
Device(config-if-gigabitethernet0/1)#interface gigabitethernet 0/2
Device(config-if-gigabitethernet0/2)#switchport mode trunk
Device(config-if-gigabitethernet0/2)#switchport trunk allowed vlan add 2
Device(config-if-gigabitethernet0/2)#exit
|
Step 2: Configure the L3 action group.
#Configure the L3 action group named LP7 and the action is to remark the packet to queue 7.
Device(config)#l3-action-group LP7
Device(config-action-group)#remark l2-priority 1p 7
Device(config-action-group)#exit
|
#Configure the L3 action group named LP6 and the action is to remark the packet to queue 6.
Device(config)#l3-action-group LP6
Device(config-action-group)#remark l2-priority 1p 6
Device(config-action-group)#exit
|
#Configure the L3 action group named LP5 and the action is to remark the packet to queue 5.
Device(config)#l3-action-group LP5
Device(config-action-group)#remark l2-priority 1p 5
Device(config-action-group)#exit |
Step 3: Configure the IP standard ACL.
#Configure the IP standard ACL with serial number 1 on Device.
Device(config)#ip access-list standard 1
|
#Configure binding the rule with the L3 action group named LP7, realizing that the authentication traffic packets are remarked to queue 7.
Device(config-std-nacl)#permit host 100.0.0.1 l3-action-group LP7
|
#Configure binding the rule with the L3 action group named LP6, realizing that the authentication traffic packets are remarked to queue 6.
Device(config-std-nacl)#permit host 100.0.0.2 l3-action-group LP6
|
#Configure binding the rule with the L3 action group named LP5, realizing that the authentication traffic packets are remarked to queue 5.
Device(config-std-nacl)#permit host 100.0.0.3 l3-action-group LP5
Device(config-std-nacl)#commit
Device(config-std-nacl)#exit
|
Step 4: Configure applying the IP standard ACL.
#Apply the IP standard ACL with serial number 1 to the ingress direction of port gigabitethernet0/1 on Device.
Device(config)#interface gigabitethernet 0/1
Device(config-if-gigabitethernet0/1)#ip access-group 1 in
Device(config-if-gigabitethernet0/1)#exit
|
#View the information of the ACL applied to the port on Device.
Device#show acl-object interface
-----------Interface-----Bind-----Instance
Interface----------------Direction----AclType---AclName
gi0/1 IN IP 1
Step 5: Configure the SP + WRR function.
#Configure the SP+WRR function on port gigabitethernet0/2, permitting all the packets of queue 7 to pass and scheduling the packets of queue 5 and queue 6 by the proportion of 1:2.
Device(config)#interface gigabitethernet 0/2
Device(config-if-gigabitethernet0/2)#queue-schedule wrr 1 1 1 1 1 1 2 0
Device(config-if-gigabitethernet0/2)#exit
|
Step 6: Check the result.
#When the traffic of port gigabitethernet0/2 is congested, the authentication traffic all passes first. The terminal traffic and video traffic pass by the proportion of 1:2.
