[KBA-00010] VSIP discovery and manual discovery process for SmartSight units in Omnicast™

This article explains the VSIP discovery process used for discovering new Verint SmartSight units on the network, and how to manually add new units which are not automatically detected in Omnicast™.

Summary

In Omnicast™, SmartSight units are automatically discovered. However, with some network configurations, the discovery process is blocked. You must understand the discovery process so you can troubleshoot when automatic discovery does not work.

Discovery by the Archiver

Periodically, the Archiver runs through a discovery process to detect new units and to make sure that the existing units are still online. By default, the Archiver repeats the discovery process every minute. If a unit does not respond after 3 rounds of the discovery process, it is considered unreachable and turns red in the system.
The discovery process includes the following three steps:
Step 1: Multicast discovery
The Archiver sends a VSIP ping request using a UDP packet to port 5510 of 224.16.32.1 (a Multicast address). These values are default values that can be changed. If the unit is configured to listen on the same multicast address and port and receives the request, it responds to the Archiver with a VSIP ping response.

The Archiver waits for 5 seconds for the responses to arrive, and then proceeds to the following step.

Step 2: Broadcast discovery
The Archiver sends a VSIP ping request using a UDP packet to port 5510 of 255.255.255.255 (a Broadcast address). The port number is the default value that can also be changed. If the unit is configured to listen on the same UDP port and receives the request, it responds to the Archiver with a VSIP ring response.

The Archiver waits for 5 seconds for the responses to arrive, and then proceeds to the following step.

Step 3: Individual discovery
The Archiver tracks all the responses received from the previous 2 steps and compares them to its list of known units. If there are any units that are registered which have not responded to the VSIP ping requests, the Archiver tries to reach those units by establishing a direct connection using TCP and UDP on port 5510. The port number is the default value that can also be changed. If the unit is configured to listen on the same TCP or UDP port and receives the request, it responds to the Archiver with a VSIP ping response.

The Archiver waits for 5 seconds for the responses to arrive before ending the discovery process.

Discovery by the unit

When a unit first boots, and periodically afterward, it sends a VSIP ping response using a UDP packet to port 5510 of 255.255.255.255 (a Broadcast address). If the Archiver is configured to listen on the same UDP port and it receives the response, the unit is discovered by the Archiver. If the unit cannot be discovered because of network related issues, it is possible to force the discovery manually in two different ways.
  • Manually adding a unit to an Archiver
  • Manually configuring a unit to connect to a specific Archiver

Manually adding a unit to an Archiver

To manually add a unit to an Archiver, the unit must have a static IP address. If the unit has a dynamic address issued through a DHCP server, then you must manually configure the unit to connect to a specific Archiver.
  1. Verify the IP connectivity by pinging the unit from the Archiver, by using the ping <ip address> command in a Windows Command Prompt.
  2. Open Omnicast™ Config Tool and logon as an Administrator.
  3. Click the Physical View.
  4. Right-click the VSIP Archiver that you want to add the unit to, and click Add VSIP Unit.
  5. Type the IP address of the VSIP unit and click Ok.

    The unit is automatically discovered during the Archiver's next discovery process if unit and the Archiver are configured with the same VSIP port.

Manually configuring a unit to connect to a specific Archiver

This manual discovery method works if the unit has either a static or dynamic IP address.
  1. Start a CLI session with the unit using telnet or a serial connection.

    If you have issues connecting to the CLI, see [KBA-00014] Cannot connect to SmartSight unit CLI in Omnicast™.

  2. Verify the IP connectivity by pinging the Archiver from the unit.
  3. From the CLI of the unit, click Network Setup > Set Ping Request, and then enter the IP address of the Archiver.
  4. Click Advanced Menu > VSIP Setup, and then enter the IP address of the Archiver for the Set VSIP Discovery IP option.

    The unit is automatically discovered during the Archiver's next discovery process if unit and the Archiver are configured with the same VSIP port.
