Token Ring Special Database

the Token Ring Special Database can be conﬁgured to ﬁlter on any part of a

packet, except its header.

A ﬁlter is based on the:

• Information within a packet – Source Address, Destination Address,

Token Ring Data Type, and Data (including the offset).

• Port designated as receiver port (where the packets are ﬁltered).

• Bridging activity on the ETWMIM’s bridge ports (e.g., forwarding/

ﬁltering).

The Cabletron Bridge Token Ring Special Database Tables for the

Token Ring Special Database application is accessed from the CT_BdgTR_App

Icon Subviews menu. The Cabletron Bridge Token Ring Special Database

Tables provide information about Token Ring Special Database ﬁlters, ports

receiving packets, and ports having special ﬁltered packets forwarded to them.

Within this view you can manipulate table entries, create ﬁlters, and delete

ﬁlters. Click on the Update button to update information in either table.

To sort and ﬁnd table entries by column heading, follow these steps:

1. Click on a column heading. The Sort and/or Find button(s) appear in the

upper-left corner of the table.

2. Click on Sort to categorize the table according to the column heading.

Click on Find to locate a speciﬁc entry.

Filter Information Table

The Filter Information Table displays the Token Ring Special Database ﬁlters.

Double-clicking on any entry accesses the Special Database Filter View. The

Special Database Filter View contains the same ﬁelds as the Filter

Information Table for the chosen ﬁlter number, and allows you to modify the

ﬁlters. The Filter Information Table provides the following information:

Filter

Displays the number of the ﬁlter. The possible range is from 1 to 19.

State

Indicates whether the ﬁlter is enabled or disabled.

Offset

Indicates the offset (in bytes, from the beginning of the data in the packet)

where the Data Mask will be applied. The default for this ﬁeld is 0000 (no data

offset). An example of a valid offset to enter into this ﬁeld is 0016.

DestinationAddress-SourceAddress-Type-PacketData Window

The four ﬁelds in this window designate what the ﬁlter is conﬁgured to search

for in a packet. Table 5-6 provides a breakdown of these ﬁlter ﬁelds.
