Airmux-200 Ver. 1.750 Changing Community Values 4-23

Use extra caution when decreasing the value, since the service quality might be

affected during interference. In cases of asymmetric interference, the jitter buffer

can be set to different values per site. Latency is also asymmetric in these cases.

4.14 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.

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).

3. Select the communities to be changed by clicking the check box.

4. Type the new community and re-type to confirm.

5. Click OK to save.
