3.8.1 Displaying the Current Protocol, VLAN ID, and
Port Assignments
In some instances it may be desirable to see which VLAN IDs and the
associated ports that are currently assigned to a particular protocol. To
display this information, proceed as follows:
1. Use the arrow keys to highlight the Protocol field at the bottom of the
screen.
2. Press the SPACE bar to step to the appropriate protocol.
3. Press ENTER. The screen displays all VLAN IDs and associated ports
currently assigned to the selected protocol.
4. If there is more information than the screen can display, use the NEXT
and PREVIOUS command at the bottom of the screen to display the
information.
3.8.2 Assigning a Protocol Family to a VLAN ID
To assign all Ether Types associated with a Protocol Family to a
VLAN ID, proceed as follows:
Ether type
(Modifiable)
Enter the values of a new Ether type when CUSTOM is
selected in the Protocol Type field.The value 0x0 will
display, which can be modified. A protocol may have more
that one Ether Type. Any Ether Type greater than 05dc
(hex) and less than ffff (hex) may be entered. The
maximum number of Ether Types configured per switch is
32. If an attempt is made to enter more that 32, an error
message, “ETHER TYPE TABLE FULL” displays.
To enter values of a particular Ether Type, refer to
Section 3.8.2.
NOTE
The list of Ether Type configurations is searched prior to the list
of “Protocol Family” configurations when a frame is received on
a switch. This means that if Ether Type of 0x0800 is configured
on port 10 with VID of 5 and IP is configured on port 10 with
VID of 6, the incoming frame will receive the VID 5 as Ether
Types have priority over “Protocol Family”.
