Ethernet Switches: Managed vs. Unmanaged

In 9Line, the /ethernetswitches endpoint allows users to manage and configure both managed and unmanaged switches. Understanding the distinction between these two types is key to properly using this endpoint.

What is a Managed Switch?

A managed switch in 9Line is a switch that:

• Supports SNMP communication: The 9Line Agent can poll the switch for detailed information about its chassis, ports, and connected devices.
• Enables Automatic Discovery: Using SNMP, 9Line can automatically discover and configure the chassis ID and ports, simplifying setup and maintenance.

What is an Unmanaged Switch in 9Line?

An unmanaged switch in the context of 9Line is defined as:

• A switch that does not support SNMP communication or where SNMP polling is disabled by the customer.
• Despite the lack of SNMP polling, you can still manually:
  • Create the switch entity and define the chassis ID.
  • Define ports and assign locations to those ports.
• No Automatic Discovery: Unlike managed switches, there is no automatic discovery of the chassis ID or ports since SNMP is not utilized.
• Integration with Webex via HELD: The Webex client can report the chassis ID and switchport ID via HELD, which is then used to assign a location if the corresponding information has been provided.

When to Use Managed vs. Unmanaged Switches

• Use Managed Switches if you want the convenience of automatic discovery and detailed monitoring capabilities via SNMP. This is ideal for scenarios where switches need to be centrally managed and frequently monitored.
• Use Unmanaged Switches if SNMP is not available, or you prefer to manually configure the switch details without relying on SNMP polling. This setup provides flexibility and is useful when SNMP is not required or feasible.
