Defining Protocol Filters
If necessary, you can define a customized protocol filter based on
EtherType, LLC, and/or SNAP. Up to six filters may be part of a protocol
filter. To define a protocol filter, do the following:
■ Create a protocol using the following command:
create protocol <protocol_name>
■ Configure the protocol using the following command:
config protocol <protocol_name> add <protocol_type>
<hex_value>
Supported protocol types include:
■ EtherType
■ LLC
■ SNAP
A maximum of seven protocol names, each containing a maximum of
six protocol filters, can be defined.
VLAN Names The Switch 3800 supports up to 64 different VLANs. Each VLAN is
given a name that can be up to 32 characters. VLAN names can use
standard alpha-numeric characters. The following characters are not
permitted in a VLAN name:
■ Space
■ Comma
■ Quotation mark
VLAN names must begin with an alphabetical letter unless quotation
marks are used to enclose a VLAN name that does not begin with an
alphabetical character, or that contains a space, comma, or other
special character.
VLAN names are locally significant. That is, VLAN names used on one
Switch are only meaningful to that Switch. If another Switch is
connected to it, the VLAN names have no significance to the other
Switch.
