Make sure the General tab is selected, and then the Layer 2 Architecture tile.

Layer 2 Architecture information is generated by AI from the device configuration information you upload. There is an executive summary showing current utilizations and highlighting areas to be addressed, a table showing a site-level Layer 2 Analysis, then a full inventory of Layer 2 Security Features showing their utilization, and a full description of the feature.

The Summary information displayed is:

Total Sites Analyzed - totalled across all regions

Total VLANs Configuration - totalled across all sites

Site-Level Layer 2 Analysis

For each site, AI generates a summary of the Layer 2 features:

Select the site whose details you want to view, and click on the down arrow. Details of the following are displayed:

• VLAN configuration - including Total VLANs, total Data VLANs, and total Voice VLANs. 
• Spanning Tree Protocol - including Protocol used, number of Root Bridges, plus (optionally) whether BPDU Guard, Root Guard and PortFast are configured.
• Trunk Configuration - including Total Trunk Ports, plus (optionally) whether Encapsulation, Native VLAN, DTP Mode are configured.

Layer 2 Security Features

This section lists the available Layer 2 Security Features, and the percantage of devices using those features across all sites.

There is also a Learn button which enables you to learn more information about each of the listed features.

Use this table to assess the maturity of your network, by Layer 2 security feature.

As a guide, the level of maturity can be assessed as:

• 90 - 100% - comprehensive security deployment
• 70 - 89% - strong security with minor gaps
• 50 - 69% - moderate security, improvement needed
• < 50% - poor, critical security gaps present
