VLANs 349
Similarly, there may be implied dependencies between encapsulations, so that
specifying an encapsulation implies defining the protocol group for related
encapsulations. An example of this is specifying the Ethernet encapsulation,
even by default, implies IEEE802 encapsulation, as per RFC 1042.
The following standards are relevant:
• IEEE802.1V defines VLAN assignment by protocol type.
• IETF RFC 10-2 defines a standard for the transmission of IP datagram

Defining Protocol Groups
Define protocol groups in two steps:
1
Define a protocol group by assigning one or more protocols to the group
and giving it a protocol-group ID (any integer), using the
Protocol Group
pages.
2
Associate the group with a desired VLAN classification, per port, using the
Protocol Port
pages.
To define a protocol group:
1
Click
Switching
>
VLAN
>
Protocol Group
in the tree view to display
the
Protocol Group: Summary
page.
The currently-defined protocol groups are displayed.
2
To add a new protocol group, click
Add
, and enter the fields:
–
Frame Type
— Select a frame type to be accepted in the protocol
group.
–
Protocol Value
— Select a protocol name.
or
–
Ethernet-Based Protocol Value (0600 - FFFF)
— Enter the Ethernet
protocol group type.
–
Protocol Group ID
— Assign a protocol group ID number.
