Analyze connections between remote sites: Difference between revisions

# You need two Allegro Network Multimeters (any model).

# One Multimeter (the master device) will receive traffic information from the remote Multimeter via a atandard SSL connection; 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.

# Install the master device in your network where it can see the traffic sent and receievd to 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.

# Install the 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.

# Remote device: There are no special configuration settings necessary on the remote device. The remote device just needs to be added as a [[Multi-device settings|multi-device]].

# Master device:

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

## Switch to the configuration tab.

## Click on the toggle button to enable the feature.

## Enter an descriptive name for the master device to make it easier to read the statistics.

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

## 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.

## Finally save the configuration settings.

## At the bottom of the page a note will appear in most cases that a restart 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); you will lose all previously measured data.

## Return to the "Generic -> Path measurement" page.

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

## 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 displayed in a information box.
