Issue
Can Sigma operate in a network environment using Layer 3 switches?
Product Line
Satchwell BAS & SigmaEnvironment
- Satchwell Sigma
- Layer 3 switches
Cause
The site is transitioning from Layer 2 switches to Layer 3 switches, prompting a need to understand Sigma’s compatibility with Layer 3 networking.
Resolution
Yes, Sigma products support IPv4 Layer 3 networking.
- Routing Protocol: Sigma uses RIP version 1 (Routing Information Protocol) for message routing.
- IP Communication: Sigma devices communicate using 32-bit IPv4 addresses with various subnet masks.
- Ensure that the Layer 3 switches are configured to support RIP v1 to maintain proper routing between Sigma devices.
Additional Notes
- RIP v1 is a classful routing protocol, which may limit subnet flexibility. Consider network design implications when planning your Layer 3 migration.
- If your infrastructure requires more advanced routing protocols (e.g., RIP v2, OSPF), Sigma may not be compatible without additional configuration or hardware.
