Port Assignment Configuration Screen Fields
The following information briefly explains each Port Assignment Configuration
Screen field.
Port Mode (Selectable)
This field can be one of the following:
•
1Q Trunk - This mode sets the port to transmit all frames with a Tag Header
included in the frame, excluding BPDUs, and a forwarding list that includes all
VLANs. The primary purpose of 1Q Trunk mode is to directly connect the
switch to other 802.1Q aware switches. The Forwarding list is modifiable to
deny access to backbone connections for certain VLAN(s).
•
1D Trunk - This mode sets the port to transmit all frames without a tag header
and a forwarding list that includes all VLANs. The primary purpose of 1D
Trunk mode is to connect the switch to a legacy 802.1D switch fabric or allow
multiple VLANs to share services while still containing their unknown traffic.
The forwarding list is modifiable to deny access to certain VLAN(s). The PVID
is the default VLAN and, if the switch is configured to Forward Default VLAN
Out All Ports, allows incoming frames to be forwarded out all ports and for any
response to be able to reach the original source.
•
Hybrid (default) - This mode has a PVID of the Default VLAN and a
Forwarding list of the Default VLAN. Any change of the PVID results in the
removal of the previous PVID from the forwarding list and replacing it with the
new PVID. There is one exception - if the switch is configured to Forward
Default VLAN Out All Ports, then the Default PVID remains on the
Forwarding List. The Forwarding list always has a frame type of untagged for
the entry that matches the PVID.
VLAN ID (Toggle)
This field toggles through all configured VLANs. Selection of a VLAN sets the
port’s PVID and also places an entry in the forwarding list for that VLAN with a
frame type as untagged. All untagged frames received on the port will be
classified into the selected VLAN. The default PVID is the Default VLAN.
VLAN Name (Read-only)
This field displays the name of the VLAN.
Next/Previous (Commands)
When the screen display is full, these commands change the ports displayed on
the screen for the selected module.
