Configure Remarking

Network Requirements

  • There are two servers in the network, that is, Video server and Data server.
  • Configure the remarking function, realizing that the 802.1p priority of the video traffic packet is marked as 5 and the 802.1p priority of the data traffic packet does not change.

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 remark and the action is to remark the 802.1p priority of the packet as 5.

Device(config)#l3-action-group remark
Device(config-action-group)#remark l2-priority dot1p 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 remark, realizing that the 802.1p priority of the video traffic packet is remarked as 5.

Device(config-std-nacl)#permit host 100.0.0.1 l3-action-group remark

#Configure the rule, permitting the data traffic to pass and not modifying the 802.1p priority of the packet.

Device(config-std-nacl)#permit host 100.0.0.2
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: Check the result.

#After the video traffic and data traffic are processed by Device, the 802.1p priority of the video traffic packet sent out from port gigabitethernet0/2 is modified to 5 and the 802.1p priority of the data traffic packet does not change.
