Configuration Tsunami MP.11 5012-SUR Installation and Management

System Parameters

• System Name: This is the system name for easy identification of the BSU or SU. The System Name field is limited to

a length of 32 bytes. Use the system name of a BSU to configure the Base Station System Name parameter on an SU

if you want the SU to register only with this BSU. If the Base Station System Name is left blank on the SU, it can

• Country: The Dynamic Frequency Selection (DFS) is enabled automatically when you choose a country with a

regulatory domain that requires it. The Country selection pre-selects and displays only the allowed frequencies for the

selected country.

Click Configure > Interfaces > Wireless to see the channel/frequency list for the selected Country.

NOTE: Units sold in the United States are pre-configured to scan and display only the outdoor frequencies permitted

by the FCC. No other Country selections, channels, or frequencies can be configured. Units sold outside of

the United States and Canada support the selection of a Country by the professional installer. If you change

the Country, a reboot of the unit is necessary for the upgrade to take place.

Support for the 5.25 – 5.35 GHz and 5.725 – 5.825 GHz frequency bands is provided with a single country selection,

UNITED STATES (US), which does not provide DFS capability in these frequency bands.

For a non US-only device, the default country selected is United Kingdom (GB).

Note the following:

– The channel center frequencies are not regulated; only the band edge frequencies are regulated.

– If, before upgrade, US was selected as a country for a non US-Only device (which is an incorrect configuration),

the country is changed automatically to United Kingdom upon upgrade.

See Country Codes and Channels for a list of country codes.

• Location: This field can be used to describe the location of the unit, for example “Main Lobby.”

• Contact Name, Contact Email, and Contact Phone: In these fields, you can enter the details of the person to

contact.

• Mode of Operation: This field lets you choose one of two operating modes: Bridge mode or Routing mode.

The static fields on this window are described as follows:

• ObjectID: This field shows the OID of the product name in the MIB.

• Ethernet MAC Address: The MAC address of the Ethernet interface of the device.

• Descriptor: Shows the product name and firmware build version.

• Up Time: The length of time the device has been up and running since the last reboot.

Bridge and Routing Modes

Bridge Mode

A bridge is a product that connects a local area network (LAN) to another local area network that uses the same protocol

(for example, Ethernet). You can envision a bridge as being a device that decides whether a message from you to

someone else is going to the local area network in your building or to someone on the local area network in the building

across the street. A bridge examines each message on a LAN, passing those known to be within the same LAN, and

forwarding those known to be on the other interconnected LAN (or LANs).

In bridging networks, computer or node addresses have no specific relationship to location. For this reason, messages

are sent out to every address on the network and accepted only by the intended destination node. Bridges learn which

addresses are on which network and develop a learning table so that subsequent messages can be forwarded to the

correct network.

Bridging networks are generally always interconnected LANs since broadcasting every message to all possible

destination would flood a larger network with unnecessary traffic. For this reason, router networks such as the Internet

use a scheme that assigns addresses to nodes so that a message or packet can be forwarded only in one general

direction rather than forwarded in all directions.
