PREDEFINED PROTOCOL FILTERS
The following protocol filters are predefined on the Summit:
•IP
•IPX
•NetBIOS
•DECNet
•IPX_8022
•IPX_SNAP
•AppleTalk
DEFINING PROTOCOL FILTERS
If necessary, you can define a customized protocol filter based on EtherType, LLC,
and/or SNAP. Up to six protocols 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>
For example:
create protocol fred
The protocol name can have a maximum of 31 characters.
•Configure the protocol using the following command:
config protocol <protocol_name> add <protocol_type> <hex_value>
Supported protocol types include:
—etype — EtherType
The values for etype are four-digit hexadecimal numbers taken from a list
maintained by the IEEE. This list can be found at the following URL:
http://standards.ieee.org/regauth/ethertype/index.html
—llc — LLC SAP
The values for llc are four-digit hexadecimal numbers that are created by
concatenating a two-digit LLC Destination SAP (DSAP) and a two-digit LLC
Source SAP (SSAP). The list of LLC SAPs can be found at the following URL:
