NSE-12 and NSE-22 quick start guide
Introduction
Network Service Element come in two varieties: SPAN and TAP.
The SPAN model has two independent monitor interfaces labeled LAN 3 and LAN 4. In a typical configuration, both ports will be connected to two SPAN output ports: one port representing all packets from the network to the site and the other port representing all packets in the opposite direction. The NSE offers great WAN visibility, including a more precise traffic measurements method than possible with flow based analysis or snmp. Other applications of NSE are possible, for example the monitoring of server bound traffic in a relatively small remote datacenter.
The fail-safe TAP model has been designed to be installed inline between the CPE and the local switch. No specific configuration of those devices is required.
Solution
Accessing the appliance
 | We recommend using MobaXterm to access the appliance. Download MobaXterm at: http://mobaxterm.mobatek.net/download.html |
The appliance is accessible through ssh using a terminal emulator program and ships with two local user accounts, Administrator and comcert. User Administrator has been created for the end-user to safely shut down and reboot the appliance. User comcert is reserved for COMCERT Support (C-TAC). To connect to NSE from another terminal session, run the following command:
ssh -l Administrator <IPaddressPMA>
Shutdown or reboot the appliance
 | All applications and virtuals machines must be brought-down properly before shutting down or rebooting the appliance. Failure to do so may result in irreparable damage to the databases and loss of recorded data. |
Connect to PMA and login as Administrator.
Once authenticated, run one of the following commands:
To shut-down the appliance:
$ sudo systemctl halt
To reboot the appliance:
$ sudo systemctl reboot
In case and only in case the above commands fail (risk of data loss):
To power-off the appliance (equivalent of removing the power source).
$ sudo systemctl poweroff
