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:
a. 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
needs to be manually configured. By changing the default mode to
1Q Trunk or 1D Trunk, the Port VLAN List and the associated
frame type is automatically configured.
b. 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.
c. 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. The 1D Trunk mode can be used in conjunction with the
"Forward Default VLAN Out All Ports" parameter and the
Default VLAN to allow all stations on a legacy portion of the
network to access all stations or servers in the 802.1Q portion of
the network.
