8.7.1 Changing the Port Mode
To change the operational mode of a port, proceed as follows.
1. Use the arrow keys to highlight the Port Mode field for the module and port combination you
wish to change.
2. Use the SPACE bar or BACKSPACE key to step through the available selections. A port may
be configured for any of the following modes:
• HYBRID – This is the default mode for all ports on the switch. The initial Port VLAN List
includes the PVID with a frame format of untagged. Any other VLANs desired for the Port
VLAN List need to be manually configured. By changing the default mode to 1Q Trunk or
1D Trunk, the Port VLAN List and the associated frame type are automatically configured.
• 1Q TRUNK – This mode sets the port for transmitting to another 802.1Q aware device. In
this mode, all frames are transmitted with a tag header included in the frame (excluding
BPDUs). The switch will drop all untagged frames it receives on the 1Q Trunk port. The Port
VLAN List for the port includes all VLANs.
• 1D TRUNK – This mode sets the port for transmitting to a legacy 802.1D switch fabric. In
this mode, all incoming frames are classified into the default VLAN and all frames are
transmitted untagged. The switch expects to receive only untagged frames through the
1D Trunk port. This mode also updates the Port VLAN List and makes the port eligible to
transmit frames for all VLANs.
3. When the desired operational mode for the port is displayed, use the arrow keys to highlight the
SAVE command at the bottom of the screen.
4. Press ENTER. The message “SAVED OK” displays.
Ingress Filtering
(Toggle) Enable or disable the ingress filtering on a port.
When ENABLED, the module will discard the incoming frames for
VLANs which do not include this Port in its Member set. When
DISABLED, the port will forward the frames.
This control does not affect VLAN independent BPDU frames, such as
GVRP and STP. It does affect VLAN dependent BPDU frames.
GVRP Status
(Toggle) Enable or disable a port to support dynamic VLANs created by the
GARP VLAN Registration Protocol (GVRP). For more information
about GVRP, refer to
Appendix A .
