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.
Note:
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.
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 the following as the current
community:
• For Read/Write community, use netman.
• For Read Only community, use public.
• For Trap community, use public-bru1.
Æ To change a community:
1. From the Configuration dialog box, select the Security tab
2. Type the current read-write community (default is netman).
