Explains how to map customer VLANs to service-provider VLANs and provides configuration guidelines for implementing Quality in Quality tunneling on trunk ports.
VLAN mappings
This topic explains how VLAN mapping translates customer VLAN IDs into service-provider VLAN IDs on Cisco Catalyst IE9300 Rugged Series Switches. VLAN mapping enables VLAN ID reuse across a shared backbone while maintaining secure traffic isolation for dispersed customer sites.
Configuration guidelines for VLAN mapping
Use these guidelines when configuring VLAN mapping on Cisco Catalyst IE9300 switches to ensure correct traffic isolation and feature compatibility. This topic describes requirements for EtherChannels, S-VLAN setup, and control traffic processing, while highlighting restrictions for Selective QnQ and trunk port operations.
Mapping customer VLANs to service-provider VLANs
This process describes how VLAN mapping translates customer VLAN IDs into unique service-provider IDs to resolve conflicts in multi-tenant environments. It outlines the stages from ingress mapping to egress restoration, ensuring traffic isolation while preserving original customer VLAN configurations across the backbone.
