DUL 20 Configuration¶

The DUL can be configured via

• OSS-RC (Ericsson operations support system-radio and core - a centralized server)
• EMA (Element Manager - a Windows WebUI utility)
• moshell (a javabased command line utility - runs on linux)
• ncli (a command line utility which runs on the DUL itself)

Configuration tools¶

EMA - Element Manager¶

There are different versions of this tool. An ancient version can be downloaded from the DUL itself:
http://169.254.1.10/em/index.html

ncli¶

With the ncli basic operations can be performed. However the ncli usually doesn't have a ManagedObject tree loaded which means it doesn't know which attributes an ManagedObject can have.

moshell¶

The most powerful tool to configure the DUL. It loads the ManagedObject on startup. But can also operate offline on backups.
See moshell for further information how to install and use it.

Backup & Recover¶

A backup of the DUL can be created via ftp and serial.
The serial is required to boot into the recovery mode.

Backup¶

Configure the serial connection to 9600 baud (alternative 115200).
Restart the DUL by removing the power for 5 seconds.
If the connection is working a boot message is shown:

Verify the address of the LMT B interface.

$ ifconfig
le0: inet 169.254.1.10 netmask 255.255.0.0 broadcast 169.254.255.255

If the address is not correct, the address can be set by:

$ ifconfig le0 169.254.1.10 netmask 255.255.0.0

The DUL should be reachable by icmp/ping and ftp.
