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.
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.
• 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
