KHIKA App for Cisco Switch

Introduction

Most of the network devices, such as firewalls, switches, routers, web proxies etc send the traffic and user activity related information in the form of logs over syslog protocol. Some applications such as Oracle database server, Symantec antivirus server, EMC SAN Storage etc also support syslog protocol as syslog is very efficient and simple to integrate with. KHIKA Data Aggregator is pre-configured with syslog services on port 514. The key parts to get here are :

1. Enabling Syslog forwarding on the device
2. Install the KHIKA App for Cisco Switch
3. Get data from your Cisco Switch into KHIKA Aggregator

How to Install the KHIKA App for Cisco Switch?

It is assumed, that you have already configured KHIKA Data Aggregator in your environment. If not, please read how to configure KHIKA Data Aggregator and perform the pre-requisite steps.

This section explains how to pick and install the KHIKA application for Cisco Switch. Installing the application shall put together and activate the adapter (parser) that can handle Cisco Switch data format, the dashboards, and the alert rules preconfigured.

Go to the “Applications” tab in the “Configure” menu.

Check whether the appropriate Workspace is selected. Note: Application is always loaded in a Workspace. Read the section KHIKA Workspaces to know more about KHIKA Workspaces. Also select your KHIKA aggregator name in the Node dropdown. This is to ensure that we are collecting data from the desired source and into the correct workspace which is ready with the configured application and components.

Click on the “+” button. A pop up appears.

User can now select the contents of the application required. For example, on the dropdown for “Reports”, click to expand it. List of all reports can be seen. User can individually select the reports required by checking on the checkbox next to each. Alternatively, check on “Select All” option to get all of them. Similarly you can select contents from Alerts and Dashboards.

Click “OK” to proceed with the installation of the selected Application. After successful installation, following status should be displayed :

This simple procedure to install a KHIKA App, automatically configures the Adapter (required for parsing the data from raw syslogs), calculated KHIKA reports on raw data, Visualizations, Dashboards and Alerts – all in one click.

How to get your Cisco Switch data into KHIKA ?

KHIKA recommends, popular syslog forwarding to monitor the Cisco Switch. You must configure the network device (or the end node) to send its logs to KHIKA Data Aggregator by providing IP address of Data Aggregator and port 514 so that the device can send its logs to KHIKA syslog service. (Please refer the documentation of individual device/vendor/OEM to understand how to configure remote syslogging for the device. Many vendors support web based configuration these days and some vendors support command based configurations)

NOTE: You will have to repeat these steps on each of the APPLICATION that you wish to monitor using KHIKA.

Alerts are generated when certain critical behavior is observed in the system – real-time and notified on the Alerts Dashboard in KHIKA as well as can be received an email to relevant stakeholders. The details of KHIKA Alerts are mentioned here Click on “Alert Dashboard” on the left menu.

Certain alerts for Cisco Switch are pre-canned and shipped with KHIKA, keeping in mind the requirements of the users. They are mentioned in the table below :

Alerts Description

Alert Details Table

Alert Name	Description	Suggested Resolution
Neighbor Down of a Switch	This alert is triggered when the event occurs such that a neighbor is in the down state.	This alert signifies that the neighbor relationship with the corresponding router/switch is down. This typically happens when Router/Switch does not receive keepalive/HELLO packets from the neighbor for a period of time longer than the Dead timer interval. If neighbor in the downstate, verify that the neighbor router is up, is running, and is properly configured for OSPF on the interface. You may refer the OEM Router/Switch manual for further information in this regard.
Command executed on switch	This alert is triggered when "cfglog_loggedcmd" message is available in the event.	Certain Commands have been executed on switch. You need to ensure that admin/configuration change commands are executed by authorized user only. White listing of common/non intrusive commands or authorized users may be done so as to avoid to avoid noisy alerts.
SLA Down on a Switch	This alert is triggered when the state changed Up to Down for SLA reachability	With Cisco IOS IP SLAs, service provider customers can measure and provide. service level agreements, and enterprise customers can verify service levels, verify outsourced service level agreements, and understand network performance. Cisco IOS IP SLAs can perform network assessments, verify quality of service (QoS), ease the deployment of new services, and assist with network troubleshooting. This alert denotes that network performance (as defined by SLAs) between multiple network locations or across multiple network paths is down/lower than expected SLAs. You should share the SLAs numbers with concerned service providers/network team so as to provide enable the to understand that SLAs are being missed and ask them to do the necessary changes so that SLAs are met.
Link down on switch	This alert is triggered when "changed state to down" message available in an event for particular switch device.	Link down on switch Admin may refer switch manual to take required action.
