Configuring The Network-Side Port; Configuring Two-To-Two Vlan Mapping - H3C S3600V2 SERIES Layer 2-Lan Switching Configuration Manual

Configuring the network-side port

Step
1. Enter system view.
2. Enter interface view.
3. Configure the link type of the
port.
4. Assign the port to all SVLANs.
5. Configure the port as a DHCP
snooping trusted port.
6. Configure the port as an ARP
trusted port.
7. Enable network-side QinQ.

Configuring two-to-two VLAN mapping

Perform two-to-two VLAN mapping on an edge device that connects two SP networks, for example, on
PE 3 in Figure
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:

Enter Layer 2 Ethernet interface

Use one of the commands.
The default link type of an Ethernet
port is access.
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.
By default, all ports are DHCP
snooping untrusted ports.
By default, all ports are ARP
untrusted ports.
By default, network-side QinQ is
disabled on all ports.
