Configuration of CiscoLEDDisplayTest

Issues with the network switch could be the source of critical infrastructural problems such as excessive bandwidth usage, slow delivery of data packets, or even worse, loss of data during transit!. The administrator can easily identify the health of the switch and Cisco device using a set of LEDs. This test reports the current status of each LED on the switches and color of each LED which can help to determine the status of the Cisco device

The default parameters associated with this test are:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, specify the HOST for which this test is to be configured.

• In the SNMPPORT text box, specify the port at which the monitored target exposes its SNMP MIB. The default port is 161.

• To instruct the eG agent to conduct the SNMP data traffic related to the monitored target over TCP (and not UDP), set DATA OVER TCP flag to YES. By default, this flag is set to NO.

• Specify the duration (in seconds) within which the SNMP query executed by this test should time out in the TIMEOUT text box. The default is 10 seconds.

• Specify the SNMP version according to the SNMP framework used in your environment, SNMP v1, v2 or v3 in the SNMP VERSION text box. By default, the eG agent supports SNMP version 1.

• Specify the SNMP community name that the test uses to communicate with the firewall in the SNMPCommunity textbox. This parameter is specific to SNMP v1 and v2 only. Therefore, if the SNMPversion chosen is v3, then this parameter will not appear.

• The eG agent should connect to the MIB using the credentials of a user with access permissions to be MIB when v3 is selected as the SNMPversion. Specify the name of such a user in the USERNAME textbox.

• If the Username provided is associated with a context name, then the eG agent will be able to poll the MIB and collect metrics only if it is configured with the context name as well. When v3 is selected as the SNMPversion, specify the context name of the Username in the CONTEXT text box.

• If v3 is selected as the SNMPversion, Specify the password that corresponds to the above-mentioned Username in the AUTHPASS textbox.

• Confirm the Password by retyping it in the CONFIRM PASSWORD text box.

• If v3 is selected as the SNMPversion, choose the authentication algorithm using which SNMP v3 converts the specified username and password into a 32-bit format to ensure security of SNMP transactions, from the AUTHTYPElistbox. You can choose between the following options:

  • MD5-Message Digest Algorithm

  • SHA-Secure Hash Algorithm

• If v3 is selected as the SNMPversion,to ensure that SNMP requests sent by the eG agent are encrypted set ENCRYPTFLAG to YES, By default, this FLAG is set to NO.

• If this Encryptflag is set to YES then you will have to mention the encryption type supported by SNMP v3 version by selecting an option from the ENCRYPTTYPE list. You can choose between the following:

  • DES-Data Encryption Standard

  • AES-Advanced Encryption Standard

• Specify the encryption password in the ENCRYPTPASSWORD text box.

• Confirm the Password by retyping it in the CONFIRM PASSWORD text box.

• If v3 is selected as the SNMPversion, sometimes, the test may not report metrics when AES192 or AES256 is chosen as the Encryption type. To ensure that the test report metrics consistently, administrators need to set ENGINEID flag to YES, By default, this FLAG is set to NO.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of “none” in the parameter value indicates that the corresponding parameter value can be changed if required.
