Configuring VLAN Translation
34
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 102 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:
• Old VLAN – The original VLAN ID. (Range: 1-4093)
• New VLAN – The new VLAN ID. (Range: 1-4093)
Interface
To configure VLAN translation:
1. Click VLAN, Translation.
2. Select Add from the Action list.
3. Select a port, and enter the original and new VLAN IDs.
4. Click Apply.
