Configuring VLAN Translation
– 190 –
the service providers VLAN ID with the customers VLAN ID for downstream
traffic.
For example, assume that the upstream switch does not support QinQ
tunneling. Select Port 1, and set the Old VLAN to 10 and the New VLAN to 100
to map VLAN 10 to VLAN 100 for upstream traffic entering port 1, and VLAN 100
to VLAN 10 for downstream traffic leaving port 1 as shown below.
Figure 103: Configuring VLAN Translation
The maximum number of VLAN translation entries is 8 per port, and up to 96 for
the system. However, note that configuring a large number of entries may
degrade the performance of other processes that also use the TCAM, such as IP
Source Guard filter rules, Quality of Service (QoS) processes, QinQ, MAC-based
VLANs, VLAN translation, or traps.
If VLAN translation is set on an interface, and the same interface is also
configured as a QinQ access port on the VLAN > Tunnel (Configure Interface)
page, VLAN tag assignments will be determined by the QinQ process, not by
VLAN translation.
Parameters
These parameters are displayed:
Port – Port identifier.
Direction - Specifies to apply VLAN translation to ingress or egress traffic, or
both.
Old VLAN – The original VLAN ID. (Range: 1-4094)
New VLAN – The new VLAN ID. (Range: 1-4094)
Web Interface
To configure VLAN translation:
1. Click VLAN, Translation.
2. Select Add from the Action list.
