Analyze connections between remote sites: Difference between revisions

1. You need two Allegro Network Multimeter of any type.

2. One Multimeter (the master device) will get traffic information from the remote Multimeter via a regular SSL connection. This means the master device must be able to connect to the remote device. If a firewall is in place between both devices, an additional rule might be necessary to connect the remote device on port 443.

1. Install the master device somewhere in your network where it can see the traffic sent to the remote site and received from the remote site. The multimeter can be installed on a mirror port on a switch which sees all the traffic, or inline between the local network and uplink to the remote site.

2. Install the remote device on the remote site at a network position where it sees all traffic from and to the local network. Again, this can be a mirror port on a switch on the remote site, or inline between the remote network and the link to the local network.

1. Remote device: There are no special configuration settings necessary on the remote device. You need the following information to use the device on the master device:

   - The TCP port under which the web site of the Multimeter is accessible (defaults to 443).

   - The username and password of the admin user (or any other user with admin role).

   1. Access the web page of the Multimeter and go to "Generic -> Path measurement".

   4. You can enter an descriptive name for the master device which makes it easier to read the statistics.

   5. For the remote device, enter the information described above. You can select a descriptive name for this device, too.

   6. Enter a maximum packet delay. This parameter defines how long the master device waits for data from the remote device until it decides whether or not a packet as been lost. Larger values requires more memory. Typical values are between 2 and 5 seconds.

   8. At the bottom of page a note will appear in most cases that arestart of the packet processing is necessary. Follow the link to the administration page and click on "Restart processing". Be aware that this will interrupt the network connection for a few seconds (if in bridge mode) and you will lose all previously measured data.

   10. The "Measurement" tab should say that the measurement status is either warming up or running.

   11. The "Remote client status" should say "connected". If not, a button appears which can be clicked to reconnect to the remote device. Any error will be printed in a info box.
