Tagging Modes of the Bridge Ports

Each frame is routed according to its VID. If the frame is untagged, it receives tag at egress from the uplink port.

Uplink and Host Ports

The uplink port operates in the following tagging modes:

•Unmodified – frames (tagged and untagged) are left unchanged.

•Tag – untagged frames are tagged and tagged frames are left unchanged.

•Stack – all frames (tagged and untagged) receive tags.

The host port of the internal bridge can be configured to add VLAN ID tags to the frames.

Management and Data Ports

The management and data ports can strip the frame tags at egress or leave the frames unchanged.

Default Tagging

Whenever the port access mode (None, MNG only or All) or forwarding mode of the bridge (Filter or Filter Tagged) is changed, the tagging modes of the bridge ports are set to one of the default tagging modes, as illustrated in Table B-1.This is made to simplify the bridge configuration procedure for the most common applications.

Table B-1. Default Tagging Modes
