Setup
With this option, you can erase the bridge database, reset counters, restore
the default settings, and disable, enable, or restart the bridge. Toggle
between the selections by pressing the Return key. You can edit the time,
date, IP Address, or the screen refresh time for the bridge. The new values
for these fields must be manually entered. From the Port Setup option you
can also set up the NB30's Redundancy feature, and DSX-1 parameters if
one is installed. This option is explained in Section 5.1.
Save Names
If you choose to assign names to a bridge, a bridge location, a network, or
a port, you can do so by entering the appropriate name(s) at the Bridge
Information Screen, and then selecting this option. This option is
explained in Section 5.2.
Port Counters
Selection of this option provides a breakdown of frame activity for each
port on the bridge. Counts of valid frames forwarded and frames received
but discarded are displayed. An additional option, the Network Errors
Option, displays the number of errors detected per port. This option is
explained in Section 5.3.
Filtering Database
With this option, you can add or delete addresses from the Source
Address Table for the Acquired Database or Permanent Database of the
Ethernet port. You can also display database statistics for the bridge.
Statistics include current and maximum number of entries in the
databases, type of filtering, and Ageing Time parameters.
The Filtering Database Option also includes a Special Database Option.
With this option, you can add or delete filters that will screen packets
according to four parameters: destination address, source address, type
(protocol), and data field. You can use the parameters individually or in
combination to filter (block) or relay (forward) certain packets. This
option is explained in Section 5.4.
