4.12 Changing Community Values

The ODU communicates with the management application using

SNMPv1 protocol. The protocol defines three types of communities:

• Read-Only for retrieving information from the ODU

• Read-Write to configure and control the ODU

• Trap used by the ODU to issue traps.

The community string must be entered at login. The user must know

the password and the correct community string in order to gain access

to the system. A user may have read-only privileges.

It is not possible to manage the ODU if the read-write or the read

community values are forgotten. A new community value may be

obtained from technical support for the purpose of setting new

community; the serial number or the MAC address of the ODU must be

supplied.

The manager application and the ODU use the community strings

public-bru1 for the local unit and public-bru4097 for the remote unit.

These are the factory defaults, but can only be used one time on the

first installation.

A new community string must be set when entering the system for the

first time. The read-write community and read-only community have a

minimum of five alphanumeric characters. (Bru1 and bru4097 are not

permitted). Changing the trap community is optional by clicking the

check box.

Note

Editing Community Strings

The community change dialog box is available from the Configuration

> Security tab. Both read-write and read-only communities must be

defined.

On entering for the first time, use netman as the current community.

The community string must be changed when entering the system for

the first time, and the community string netman cannot be used again.

To change a community:

1. From the Configuration dialog box, select the Security tab

2. Type the current read-write community (default is netman).
