With version 3.6 uploading a new certificate adds to the old one. You can delete all by pressing the "Remove all CA certificates" and also remove separate certificates. | With version 3.6 uploading a new certificate adds to the old one.

=== Time Settings === | |||
The Allegro Network Multimeter can be configured to use a time synchronization service. NTP is supported for all variants of the Allegro Network Multimeter. PTP service may be used if management interface supports hardware time stamping. If a GPS-capable PTP grandmaster card is available, GPS time synchronization is available and the antenna cable delay in nanoseconds can be configured. | |||
To enable a time service, switch to the desired type in the dropdown box. The time service field will show whether the selected service is running or not. | |||
'''NTP''' - For active NTP time retrieval, you can specify and edit dedicated NTP servers the Allegro Network Multimeter should communicate with. If you do not specify a NTP server, a set of predefined NTP servers will be automatically selected. | |||
'''NTP from data plane''' - For passive time retrieval, NTP from data plane can be used to retrieve the time to be synchronized passively from NTP packets within the traffic that is analyzed. The IP address of a desired NTP server must be set. As soon as a NTP server packet is seen, the system time of the Allegro Network Multimeter will be set. The wait period field can be used to set a time period where subsequent updates are ignored. If set to 0, every time packet of that server will be used. NTP from data plane is ideal in situation where the Allegro Network Multimeter MGT interface can not or may not actively connect to the network. | |||
'''PTP''' - For PTP time retrieval, the PTP grandmaster clock identity is shown. This is usually an EUI-64 address. The first and last set of octets of the identity represent the (EUI-48) MAC address of the grandmaster. | |||
The following settings are possible for PTP and should match the settings of the PTP grandmaster: | |||
*Delay mechanism: Use end-to-end (E2E), peer-to-peer (P2P) or automatic delay measurement. In case automatic measurement is selected, E2E is used at the beginning and switched to P2P when a peer delay request is received. Default is '''Auto'''. | |||
*Network transport: Use UDPv4, UDPv6 or Layer 2 as network transport. Default is '''UDPv4'''. | |||
*Domain number: The domain number of the grandmaster. This is used to define logical groups of synchronized clocks. | |||
'''GPS''' - The GPS time retrieval option will become available when a GPS capable PTP grandmaster card is installed in the Allegro Network Multimeter. | |||
If no time synchronization mechanism is selected the date and time of the device can be manually configured by entering a properly formatted date and time description. Below the time synchronization settings, the time zone used by the device can be configured. The drop-down list provides a list of cities grouped by world regions to select the appropriate time zone. | |||
When a nanosecond-resolution capture card with support for '''PPS'''-synchronization is installed, the toggle ''Enable PPS synchronization'' can be used to enable this type of synchronization. It is only shown when the time service chosen is not ''GPS'' as those two modes cannot be used simultaneously. The time offset in nanoseconds is also configurable allowing to compensate for the PPS connection cable length. This feature should only be enabled when it is made sure that a proper PPS signal is provided to the network adapter. Otherwise the packet timestamps may be incorrect. | |||

=== Email notification === | |||
Certain modules support the sending of email notifications. The following settings are used to globally configure the SMTP server used and the target email address that will receive the notifications: | |||
*Enable email notifications: globally enables or disables the sending of email notifications. | |||
*SMTP server address: the address of the SMTP server that will be used to send notification emails. | |||
*SMTP server port: the TCP port on which the SMTP server is listening. | |||
*SMTP server uses SSL: must be set to On if the SMTP server expects an SSL connection from the very start. If the SMTP server uses no SSL or STARTTLS this setting must be set to Off. | |||
*Ignore certificate errors: if the SSL certificate should not be validated because e.g. it is a self-signed certificate this setting can be used to turn off certificate validation. | |||
*Allow unencrypted connections: if an unencrypted connection must be allowed because e.g. a legacy SMTP server does not support it this setting can be used. | |||
*Username: the username used to log in to the SMTP server. | |||
*Password: the password used to log in to the SMTP server. | |||
*From email address: the email address from which incident notifications will be sent. | |||
*Target email address: the email address to which incident notifications will be sent. | |||
*Email links base URL: this base URL will be used to generate the HTML links in notification emails. Since the device cannot by itself determine the proper address by which it is visible to the email recipient this setting can be used to set the correct URL prefix for links sent with the notification emails. | |||
*Send periodic system status mail: if set to hourly or daily, a periodic system status report email will be sent to the configured target address with the selected frequency. It will contain basic system information and system health status, management interface configuration and a list of detected LLDP neighbours if the management LLDP feature is enabled. | |||
The Send test email button can be used to verify that the entered settings are working. | |||
