BRIDGE FILTER CONFIGURATION ELEMENTS

PROTOCOL DEFINITION CONFIGURATION ELEMENTS

ROTOCOL NAME

A user-defined name for the protocol to be filtered. It can be from 1 to 17 alphanumeric characters

in length.

THERNET TYPE IN HEX

A four digit hexadecimal number (from 0600 to FFFF) that checks the protocol Id of a MAC frame.

LSAP

IN HEX

A four digit hexadecimal number (from 0000 to FFFF) that checks the protocol Id of a MAC frame.

RIDGE FILTER CONFIGURATION ELEMENTS

FILTER ACTION

For each filter category, there are three filtering actions that the system can perform on a packet:

discard, forward, or connect the packet.

MAC-A

DDRESS

An assigned Media Access Control address as defined by IEEE 802.3 specifications. MAC-

addresses are specified as 12 character hexadecimal numbers.

ULTICAST ADDRESS

A Media Access Control address with the group bit set to 1.

ISTRIBUTION LIST

A distribution list is defined as the WAN and/or LAN ports to which the filter action will be

applied. The distribution list is selected from a displayed list of possible choices (LAN, WAN,

Device Table, or all destinations).

ASK

Hexadecimal number up to 80 characters in length that specifies which bits in the data packets are

significant. There must be an even number of hexadecimal digits in the number. A scale will be

displayed to help you enter the Mask accurately.

ATA VALUE

Hexadecimal number up to 80 characters in length that specifies the value used to determine if the

packet matches the filter. The value field must be a subset of the mask field. That is, the value field

logically “anded” with the mask field must be equal to the value field. The value and mask fields

must have equal lengths. There must be an even number of hexadecimal digits in the number.

ACKET OFFSET

A decimal number between 1 and 100 that indicates the starting offset in a data packet where a

packet filter will begin its data comparison.

ROTOCOL-ID

The symbolic name for the Ethernet protocol to be filtered. The protocol-Id is selected from a

displayed list of previously defined protocols. (Refer to the section titled Protocol Definitions.)
