You’ll see Overview, Connectivity, Anomalies, and Advisories that will provide more information on the switch, with Overview shown first by default.
Overview
The Overview tab shown first by default when you view switch details. The following appear below Overview.
-
Anomaly level :
Hover over the Anomaly Level to see what category the anomalies belong to. Click the Anomaly Level to get more specific information on the anomalies present for this controller. A slide-in appears, showing all the anomalies that occurred for this controller. See Anomalies to understand how to navigate across the anomalies.
-

Hover over the Advisory Level to see what category the advisories belong to. Click the Advisory Level to get more specific information on the advisories present for this switch. A slide-in appears, showing all the advisories that occurred for this switch. See Advisories to understand how to navigate across the advisories tab.
-
Interfaces :
Interfaces provides the following information:
-
The total number of interfaces in this switch
-
The number of physical interfaces
-
The overall status of the interfaces in the switch (the number of interfaces that are up, down, or physical not in use)
Click on the number above the Total text to get additional information on the interfaces in this switch.
You can filter the list of interfaces based on Anomaly Level, Interface, Type, Operational status and Admin status. Click on a specific interface listed under the Interface column to get additional information on that particular interface. See Interfaces for more information.
-
-
Switch View :
Within the Switch View, you can see the status of the interfaces, where the state could be Up (green),Down (red), or Not in Use (gray).
If the switch has multiple modules installed, you can switch the views between the different modules.
Real Time Visualization (RTEV) feature facilitates real-time event rendering within a user interface (UI) environment. This feature allows for the smooth integration of real-time events directly into the UI, ultimately enhancing the user experience and delivering the most up-to-date information in real-time. RTEV supported features provide the current data in 10 seconds when the change happens which otherwise takes 5 minutes to get updated via the regular pipeline.
Real-time values are shown to the right of the vertical bar. Historical values (past 2 hours) are shown to the left of the bar and may have larger gaps between data points.
Controller events are not real time and RTEV is limited to switches only. Only 10 sessions per pod can have real-time data for physical and virtual deployment profiles. If there are more than 10 sessions then the data will be sent via regular pipeline. All other deployment profiles support 20 sessions.
Click View All to see the switch view for all modules installed. Click these links in the Switch View to get additional information:
View Hardware Resources :
Click View Hardware Resources to view a slide-in which appears with information on the hardware resources for this switch in real time.

The hardware resources displayed with the percentage utilized per component are CPU, Fan Utilization, Memory, Power Supply, Storage, and Temperature. Click any resource to view further details about it.
For hardware resources all parameters are updated in real-time based on the cadence from the switch when it sends the data.

Supported Interface Types (Real time visualization)
-
Physical Interface: To view the interface details of the node such as,node name, physical interface name, operational status, and admin state. The page also displays protocols, QoS, and DOM properties of the physical interface.
-
Port Channel Interface: The port channel is an aggregate of physical interfaces and they can be statistically channeled or can be dynamic using LACP protocols. The statistical data that collects the counters for packets, bytes and various errors are similar to that of physical interface. The 150 sourcename differentiates the physical interface from port-channel (aggregated interfaces). The operational data is obtained by looking at an additional set of objects that gives the admin-status, oper-status and list of member interfaces for both PC and vPC.
-
vPC Interface: The vPC is a logical interface that spans across two physical switches for fault tolerance. For a vPC interface type, the Logical Neighbors information is also displayed. The categories that are supported are L3Out, IPN, ISN, L4-L7.
-
SVI Interface: An SVI is a virtual routed interface that connects a VLAN on the device to the Layer 3 router engine on the same device. Specific information such as Member Interfaces over which the SVI is deployed, VLAN ID, VLAN Type, Encap VLAN are displayed for the SVI interface.
Click an interface to view more details about it.

Filtering Information
In some cases, you might be able to filter results to find information more easily.
For example, you might have a situation where there a large number of endpoints under a single leaf switch, but you are only interested in endpoints that have a certain VLAN value.
You could filter the information to show only those specific endpoints in this situation.
Use the following operators for the filter refinement:
| Operator | Description |
|---|---|
|
== |
With the initial filter type, this operator, and a subsequent value, returns an exact match. |
|
!= |
With the initial filter type, this operator, and a subsequent value, returns all that do not have the same value. |
|
contains |
With the initial filter type, this operator, and a subsequent value, returns all that contain the value. |
|
!contains |
With the initial filter type, this operator, and a subsequent value, returns all that do not contain the value. |
|
< |
With the initial filter type, this operator, and a subsequent value, returns a match less than the value. |
|
< = |
With the initial filter type, this operator, and a subsequent value, returns a match less than or equal to the value. |
|
> |
With the initial filter type, this operator, and a subsequent value, returns a match greater than the value. |
|
> = |
With the initial filter type, this operator, and a subsequent value, returns a match greater than or equal to the value. |
