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:

—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:
