DES-7200 Configuration Guide Chapter 12 QinQ Configuration
12-14
Note
Flow-based outer VID change policy table takes
precedence over protocol-based outer VID change policy
table.
When you configure member port on AP, the configured
VID add policy or VID change policy will be deleted.
Reconfiguration of VID add policy or VID change policy is
necessary. It is recommended to configure VID policy on
AP after configuring member port.
Once ACL is deleted, the ACL related policies will be
deleted as well.
If a packet matches two or more flow policies without
priority specified simultaneously, the early configured
policy takes effect.
Note
This function is supported on the 7200-24, 7200-24G, 7200-48,
7200-48P, 7200-2XG, 7200-4XG, 7200-24GE and
7200-24G2XG line cards of DES-7200 series.
The following example changes the VID of inner tag as 6 for the packets to
1.1.1.2:
DES-7200# configure
DES-7200(config)# ip access-list standard to_6
DES-7200(config-acl-std)# permit host 1.1.1.2
DES-7200(config-acl-std)# exit
DES-7200(config)# interface gigabitEthernet 0/1
DES-7200(config-if)# switchport mode trunk
DES-7200(config-if)# traffic-redirect access-group to_6 inner-vlan 6 out
DES-7200(config-if)# end
Caution
When you configure flow-based policy table, inner VID is
necessary to match user VID, or otherwise outer VID is
matched.
