What Are the Differences in AP-side Switch Interface Configuration and Intermediate Switch Configuration in Direct and Tunnel Forwarding Modes?
Differences in configurations on switch interfaces connected to APs are as follows:
- In tunnel forwarding mode, interfaces connected to APs transparently transmit only packets of the management VLAN. These interfaces must be added to the management VLAN in untagged mode.
- In direct forwarding mode, interfaces connected to APs must be trunk or hybrid interfaces. These interfaces must be added to the management VLAN in untagged mode and added to service VLANs in tagged mode. If a trunk interface is connected to an AP, the PVID of the interface must be set to the management VLAN ID.
Differences in configurations on intermediate switches are as follows:
- In tunnel forwarding mode, intermediate switches transparently transmit only packets of the management VLAN.
- In direct forwarding mode, intermediate switches transparently transmit packets of both the management VLAN and service VLANs.
