Configuring the network-side port
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter interface view.
•
Enter Layer 2 Ethernet interface
view:
interface
interface-type
interface-number
•
Enter Layer 2 aggregate
interface view:
interface bridge-aggregation
interface-number
N/A
3.
Configure the link type of the
port.
•
Configure the port as a trunk
port:
port link-type
trunk
•
Configure the port as a hybrid
port:
port link-type hybrid
Use one of the commands.
The default link type of an Ethernet
port is access.
4.
Assign the port to all SVLANs.
•
Assign the trunk port to VLANs:
port trunk permit vlan
{
vlan-list
|
all
}
•
Assign the hybrid port to VLANs
as a tagged member:
port hybrid
vlan
vlan-list
tagged
Use one of the commands.
By default:
•
A trunk port is assigned only to
VLAN 1.
•
A hybrid port is an untagged
member of VLAN 1.
5.
Configure the port as a DHCP
snooping trusted port.
dhcp-snooping trust
By default, all ports are DHCP
snooping untrusted ports.
6.
Configure the port as an ARP
trusted port.
arp detection trust
By default, all ports are ARP
untrusted ports.
7.
Enable network-side QinQ.
qinq enable
uplink
By default, network-side QinQ is
disabled on all ports.
Configuring two-to-two VLAN mapping
Perform two-to-two VLAN mapping on an edge device that connects two SP networks, for example, on
. Two-to-two VLAN mapping enables two remote sites in different VLANs to
communicate at Layer 2 across two service provider networks that use different VLAN assignment
schemes.
For the ease of description, the VLAN tags of the double-tagged frames that arrive at the customer-side
port are called foreign CVLANs and SVLANs, and the VLAN tags marked by the edge device are called
local CVLANs and SVLANs.
Perform these tasks to configure two-to-two VLAN mapping:
Task Description
Configuring an uplink policy for the
customer-side port
Replaces foreign SVLANs with local SVLANs for uplink traffic
(required).
