                                                Monitoring a vPC

                                                The virtual port channel (vPC) feature enables you to view the links that are physically connected to different devices as a single port channel. A vPC is an extended form of a port channel which allows you to create redundancy and increase bisectional bandwidth by enabling multiple parallel paths between nodes and allowing load balancing traffic. Traffic is distributed among two single device vPC end points. If there is an inconsistency in the vPC configurations, the vPC does not function correctly.


                                                Note

                                                To view the vPC in vPC Performance, both primary and secondary device should be designated to the user. If either one kind of switch is not designated, vPC information will not displayed.

                                                      Creating SAN User Defined Reports

                                                      You can create custom reports from all or any subset of information obtained by Cisco DCNM-SAN. You create a report template by selecting events, performance, and inventory statistics you want in your report and set the desired SAN, fabrics or VSAN to limit the scope of the template. You can generate and schedule a report of your fabric based on this template immediately or at a later time. DCNM Web Client saves each report based on the report template used and the time you generate the report.

                                                      Since the Cisco MDS NX-OS Release 5.0, the report template design has changed to resolve the limitations of the earlier versions. With the new design model, you can perform add, delete, and modify functionalities on a single page. You can choose multiple fabrics and VSANs using the new navigation system, which allows you to add new items and categories in the future.

                                                      The new design model has three panels:

                                                      • Template panel - The Template panel allows you to add new templates, modify existing templates and delete existing templates.
                                                      • Configuration panel - The Configuration panel allows you to configure a new template when it is added, and modify an existing template. The options in the configuration panel are disabled until you either add a new template or select an existing template. The upper portion of the configuration panel contains many categories that you can choose and configure.
                                                      • User Selection panel - The User Selection panel displays your configuration options in real-time. While the configuration panel can display information pertaining to one category at a time, the User Selection panel displays all of your selections or configurations.

                                                              This section contains the following:

                                                              Compare Configuration Files

                                                              This feature allows you to compare one version of a configuration file with another version of the same configuration file in the same device, or the configuration files of two different devices.

                                                              Perform the following task to compare configuration files.

                                                              Procedure
                                                                Step 1   In the Cisco DCNM web client home page, choose Monitor > Configuration > Archives.
                                                                Step 2   In the Archives area, click the arrow adjacent the name of the device whose configuration files you want to view. The list of configuration files is displayed.
                                                                Step 3   Check the check box next to configuration files and select two configuration files to compare.

                                                                The first file you select is designated as source and the second configuration file is designated as the target file.

                                                                Step 4   Click Compare.

                                                                The View Config Diff page displays the difference between the two configuration files.

                                                                The Source and Target configuration files' content are displayed in two columns. From the drop-down list in the right-top corner, choose All to view the entire configuration or choose Changed to view the configuration differences between the configuration files.

                                                                The differences in the configuration files are shown in a table, with legends.

                                                                Red—Deleted configuration details

                                                                Green—Newly added configuration

                                                                Blue—Modified configuration details

                                                                View or Edit Configuration

                                                                You can view an archived configuration file, or you can edit and save this file on your local system. The changes made to the archived configuration file is applied only to the file saved in your local system. The archived configuration file on the DCNM host server remains unchanged.

                                                                Perform the following task to view or edit the configuration file for the devices.

                                                                Procedure
                                                                  Step 1   In the web client home page, choose Monitor > Configuration > Archives.
                                                                  Step 2   In the Archives area, click the arrow adjacent the name of the device whose configuration files you want to view. The list of configuration files are displayed.
                                                                  Step 3   Click the radio button adjacent the corresponding file you want to view or edit.
                                                                  Step 4   Click the View/Edit configuration icon.

                                                                  The View/Edit configuration window appears showing the configuration file content in the right column.

                                                                  Step 5   Edit the configuration file as required.
                                                                  Step 6   Click Save to apply the changes and download the configuration file on your local system, or click Cancel to discard changes.

                                                                  Exploring Endpoint Locator Details

                                                                  Procedure
                                                                  From the menu bar, choose Monitor > Endpoint Locator > Explore. The Endpoint Locator dashboard appears. The Endpoint Locator Dashboard displays the following information:

                                                                  • Endpoint History—Real time plot displaying Endpoint events for the period specified in the relative or absolute date range. A user can search for a specific metric value in the search bar. Search is supported on any of the fields as specified under the “Available Fields” column on the menu on the left. A sample screenshot of the endpoint history based on an IP address specified in the search field is depicted below.

                                                                  • Endpoint Activity—This view displays the current state of the active endpoints in the fabric. The number of active endpoints including the number of active VRFs and active networks are listed in the top 3 tiles. The break-up of active endpoints is also available on a per VRF as well as a per switch basis. This is depicted by the first two tiles in the second row. If there is at least one active endpoint in a given VRF behind a switch, then that VRF is considered as active on that switch. Note that the VRF may be configured on a number of switches but it is only considered active and justifies burning resources on the switch, if there is at least one active endpoint in that VRF behind that switch. In that sense, the “ACTIVE SWITCHES BY VRF” tile can provide a good insight for the network administrator into removing extraneous VRF configurations from switches where it may not be needed. At the bottom of the dashboard, there is a data table that provides a list of endpoints with context information such as the VRF, IP, MAC, Switch, VLAN, Port etc. By default, the endpoint information is refreshed every 30 seconds. However, the refresh interval may be changed as desired.

                                                                    Users can search for specific endpoints using various search filters such as VRF, switch, IPv4/IPv6 address etc. Multiple filters may be applied at the same time. The entire dashboard view across all tiles and the data table, are updated as soon as the search filters are applied. The search results can be downloaded in csv format by clicking on the “DOWNLOAD RAW” icon. A sample snippet of the downloaded csv file from a search result is shown below:

                                                                    It is possible to search based on any of the fields describing the information of each endpoint. For example, if the user wants to know the list of endpoints in a given network, that can be achieved as follows. Recall that each network is represented by a unique 24-bit identifier. This parameter is represented by the field L2_VNI. Here are the steps:

                                                                    1. Go to the ‘List of endpoints’ data table and click on any row. This will expand the row as shown below:

                                                                    2. Click on the + icon next to the L2_VNI field. This selects the highlighted value (10000 in this example) and filters the search results based on that. In other words, the information of all active endpoints in the network associated with L2_VNI 10000 is displayed on the dashboard. If instead, all endpoints that are not in the network L2_VNI are required, click the – icon next to the L2_VNI value of 10000. In the same manner, one can choose any combination of fields to get the set of endpoints matching the corresponding selected filter criteria.

                                                                  • Network Historical View— The NHV view displays historical information of endpoints, networks, and VRFs (tenants) captured on a daily basis. These graphs are updated once a day at mid-night based on the DCNM server time. The time at which the data is refreshed/updated is listed at the top right. The idea is to provide a daily report of the Active, Added (New) and Deleted endpoints, networks, and VRFs respectively. If the same endpoint is added and removed on a day, then that contributes to an add count of 1 and a delete count of 1. Users can select one of the 3 dots at the bottom to toggle between the endpoints, networks, & VRF views. There are options to zoom in/out using zoom icons on top right. The users can also select the type of visualization with the choices being – Grouped or Stacked (shown below). Daily reports up to 180 days in the past can be displayed. Active endpoints/networks/VRFs are shown in blue color, deleted ones are shown in red color while the added ones are shown in green color. Every block in all screens is ‘clickable’ and the complete dataset associated with the selection, can be downloaded in csv format.

                                                                    The historic endpoint count in ‘Stacked’ format is shown below:

                                                                    The same representation with the Grouped visualization selection is shown below:

                                                                    Similarly, the figure below depicts the historic network count in stacked format:

                                                                    Along the same lines, the figure below depicts the historic vrf count:

                                                                    The figure below provides a sample screenshot of the endpoints added on 01-03-2018 obtained by clicking on the blue bar for that day.

                                                                  • Operational Heatmap—This view displays a heat-map of all endpoint operations occurring in the fabric.

                                                                    The heat-map is color coded and the intensity of the color varies based on the number of endpoint operations captured on an hourly basis. The break down is available per hour across dates, and user can see the details of operations that occurred during a particular hour on a particular day by clicking on the appropriate square. The figure below depicts the endpoint operations reported by BGP on 01-02-2018 between 12 and 1pm.

                                                                    Again, as with the other views, the complete data set can be downloaded in csv format using the Download option. A sample screenshot of a downloaded csv file is shown below:

                                                                  • Endpoint Life—This view displays a time line of a particular endpoint in its entire existence within the fabric. Specifically, given an identity of an endpoint in terms of its IP address and VRF/Network-identifier, the output displays the list of switches that an endpoint was present under including the associated start and end dates. This view is essentially the network life view of an endpoint. If the endpoint is viewed as active by the network, it will have a band here. If an endpoint is dual-homed, then there will be 2 horizontal bands reporting the endpoint existence, one band for each switch (typically the VPC pair of switches). As endpoints move within the network, for example with VM move, this view provides a succinct and intuitive pictorial view of this activity.

                                                                    The underlying data that drives this view can also be downloaded in csv format (shown below) by clicking on download icon on right bottom corner.
