USER’S GUIDE

BRIDGE FILTER CONFIGURATION ELEMENTS

PROTOCOL DEFINITION CONFIGURATION ELEMENTS

PROTOCOL NAME

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

ETHERNET 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.

BRIDGE 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-ADDRESS

An assigned Media Access Control address as defined by IEEE 802.3 specifications. MAC- addresses are specified as 12 character hexadecimal numbers.

MULTICAST ADDRESS

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

DISTRIBUTION 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).

MASK

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.

DATA 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.

PACKET 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.

PROTOCOL-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.)
