Certification to the Connectivity Level means the product can be physically connected, installed, operated, reinstalled and disconnected to/from an Industrial IT system.
The product will exchange information with the Industrial IT system via defined interfaces, and basic data – e.g. the most frequent operational data -- can be handled reliably over at least one defined protocol.
The product is certified not to introduce disturbances in the environment where it is deployed.
Cisco products certified to Level 1 include the Catalyst 2955 industrial ethernet switches. They are considered to be generic devices. This means:
Cisco equipment has been tested and proven not to interfere with the operation of an Industrial IT control network.
The Cisco CMS software can be integrated by configuring a Web Page aspect (User Interface Integration).
In the server network, add Cisco CMS Application by adding a web page aspect to access port statistics and performance graphics.
Faceplates can also be added as aspects to monitor port status data. Alarms can be configured in PPA based on the status of the ports.

Intelligent Ethernet is Critical for Industrial Ethernet Deployments Security Availability QoS
Robust access control
SSH, Intrusion Detection, L2-L4 ACLs, etc.
Different data traffic models require intelligence to guaranty scalability and resilience of the network
Control Networks MUST prioritize Control Traffic over Configuration, Data Collection and other applications to ensure deterministic data flows with low latency and low jitter
Control Video Data (Best-Effort) Voice Bandwidth Low to Moderate Moderate to High Moderate to High Low to Moderate Random Drop Sensitivity High Low High Low Delay Sensitivity High High Low High Jitter Sensitivity High High Low High
Multilayer Quality of Service (QoS) Application Device Profiles L2 Data Link L1 Physical L3 Network L4 Transport Fieldbus Specific QoS Parameters
The Catalyst 2955 allows for traffic prioritization based on MAC address, IP address, type of traffic (control, data, voice, etc. based on L4 port number)
