Ingress VLAN and Egress Tagging

Ingress VLAN functionality allows customers to assign dedicated VLAN Tags to ingress traffic, creating a mapping between the Network port and tool ports.

Traffic received on network ports can be added with an additional VLAN tag and sent towards the tools for identifying the Network Port(with the assigned VLAN tag).

The following image shows a visual representation of Ingress VLAN and Egress Tagging:

Configuration:

1. Configure Network/Tool port(s)

2. Configure ingress VLAN

3. Enable egress tagging on tool port(s)

4. Configure flow

5. Verify

By default, the Interface will have a native VLAN of n+2 (i.e. Eth12 will have a tag of 14)
