Add Tags to Map Rules

You can associate tags to the map rules. Each rule within a map can be associated with different tag keys and tag values. Tagging at rule level allows you to view the statistics of the flow of traffic based on the rules associated to the traffic.

Consider the following maps and map rules associated to tags:

Maps	Tag Key	Tag Value
Map 1 Src: 1/1/x1 Dst: 1/1/x2	Maptag	M1
- Rule 1 Vlan 100	Flow	Flow1
- Rule 2 Vlan200		Flow2
Map 2 Src: 1/1/x3 Dst: 1/1/x4	Maptag	M2
- Rule 1 Vlan 100	Flow	Flow1
- Rule 2 Vlan200		Flow2

With rule-level tagging, you can view the traffic flow associated with Rule 1 of both the Maps based on the tag value Flow1, even though the rules are defined as part of different maps. Refer to the Map Rule Statistics Dashboard section for viewing statistics related to the flow of traffic based on the rules defined.

To associate tags to map rules:

1. When creating a map, click on Add a Rule.
2. Add the required tags to the rule.

Notes

Refer to the following notes:

• Rule level tagging is applicable for:
  • Flow Maps
  • Fabric Maps
• Rule level tagging is applicable for the following map types:
  • Regular Maps
  • First Level Maps
• You can associate only aggregation tags with map rules. However, traffic statistics displayed in the Map Rule Statistics dashboard is based on the following
  • RBAC tags associated at the map level.
  • Aggregation tags associated at the rule level.

Map Rule Statistics Dashboard

The Map Rule Statistics dashboard displays statistical data related to the map rules and the associated traffic. To view the Map Rule Statistics dashboard:

1. On the left navigation pane, select -> Analytics -> Dashboards.
2. Click Dashboards from the top menu. Select Map Rule Statistics from the list of dashboards.

The Map Rule Statistics dashboard is displayed. The visualizations are displayed in the following two tabs:

• Metric
• Trend

The Metric tab displays the following visualizations

• Total Traffic: Total traffic in packets per second
• Average Traffic: Average traffic in packets per second
• Associated Map Rules: Map rules associated with the traffic

The Trend tab displays the following visualizations:

Visualizations	Displays...
Maximum vs. Average Traffic in pps	Maximum traffic versus average traffic in packets per second on an hourly interval.
Maximum vs. Average Traffic in bps	Maximum traffic versus average traffic in bytes per second on an hourly interval.
Traffic Distribution at Rule Level in pps	Traffic distribution at rule level in packets per second.
Top-N Rules by Maximum Traffic in pps	Top 5 rules contributing to the maximum traffic in packets per second
Top-N Rules by Average Traffic in pps	Top 5 rules contributing to the average traffic in packets per second

Use the following 'Control Visualizations' to filter the traffic:

• Flow Sample
• Cluster ID
• Host Name
• Map Rule Sample

Customize the Flow Sample and Map Rule Sample options to filter the data based on the tags configured in GigaVUE-FM. Refer to the Filter Data Using Tags in Control Filters section for more details.

Note:  Refer to the Fabric Health Analytics section for information about filtering and searching in the dashboards page.
