XClarity Adaptor Network Port Status Test

The XClarity Controller uses two network controllers. One network controller is connected to the dedicated management port and the other network controller is connected to the shared port. Each of the network controllers is assigned its own burned in MAC address. If DHCP is being used to assign an IP address to the XClarity Controller, when a user switches between network ports or when a fail-over from the dedicated network port to the shared network port occurs, a different IP address may be assigned to the XClarity Controller by the DHCP server.

The health of Network Adaptor Ports is vital to the commmunication and overall functioning of controller, any issue with ports can affect the ability of controller to communicate.

This test auto-discovers the ports and reports metrics like port number, status and link speed of the port. If administrators find that link status is down or speed is low, then can take corrective actions in timely manner.

Target of the test : A Lenovo XClarity Controller

Agent deploying the test : An external agent

Outputs of the test : One set of results for each Network Adaptor port on XClarity Controller.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the target server that is being monitored.

SNMPPort

The port at which the monitored target exposes its SNMP MIB;

Data Over TCP

By default, in an IT environment, all data transmission occurs over UDP. Some environments however, may be specifically configured to offload a fraction of the data traffic – for instance, certain types of data traffic or traffic pertaining to specific components – to other protocols like TCP, so as to prevent UDP overloads. In such environments, you can instruct the eG agent to conduct the SNMP data traffic related to the monitored target over TCP (and not UDP). For this, set this flag to Yes. By default, this flag is set to No.

Timeout

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

SNMPVersion

By default, the eG agent supports SNMP version 1. Accordingly, the default selection in the SNMPversion list is v1. However, if a different SNMP framework is in use in your environment, say SNMP v2 or v3, then select the corresponding option from this list.

Context

This parameter appears only when v3 is selected as the SNMPVERSION. An SNMP context is a collection of management information accessible by an SNMP entity. An item of management information may exist in more than one context and an SNMP entity potentially has access to many contexts. A context is identified by the SNMPEngineID value of the entity hosting the management information (also called a contextEngineID) and a context name that identifies the specific context (also called a contextName). 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. In such cases therefore, specify the context name of the Username in the Context text box.  By default, this parameter is set to none.

Username

This parameter appears only when v3 is selected as the SNMPversion. SNMP version 3 (SNMPv3) is an extensible SNMP Framework which supplements the SNMPv2 Framework, by additionally supporting message security, access control, and remote SNMP configuration capabilities. To extract performance statistics from the MIB using the highly secure SNMP v3 protocol, the eG agent has to be configured with the required access privileges – in other words, the eG agent should connect to the MIB using the credentials of a user with access permissions to be MIB. Therefore, specify the name of such a user against this parameter. 

Authpass

Specify the password that corresponds to the above-mentioned Username. This parameter once again appears only if the SNMPversion selected is v3.

Confirm Password

Confirm the AuthPass by retyping it here.

AuthType

This parameter too appears only if v3 is selected as the SNMPversion. From the AuthType list box, 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. You can choose between the following options:

  • MD5 - Message Digest Algorithm
  • SHA - Secure Hash Algorithm
  • SHA224 - Secure Hash Algorithm 224 bit
  • SHA256 - Secure Hash Algorithm 256 bit
  • SHA384 - Secure Hash Algorithm 384 bit
  • SHA512 - Secure Hash Algorithm 512 bit

EncryptFlag

This flag appears only when v3 is selected as the SNMPversion. By default, the eG agent does not encrypt SNMP requests. Accordingly, the this flag is set to No by default. To ensure that SNMP requests sent by the eG agent are encrypted, select the Yes option. 

EncryptType

If the EncryptFlag is set to Yes, then you will have to mention the encryption type by selecting an option from the EncryptType list. SNMP v3 supports the following encryption types:

  • DES - Data Encryption Standard
  • 3DES - Triple Data Encryption Standard
  • AES - Advanced Encryption Standard
  • AES128 - Advanced Encryption Standard 128 bit
  • AES192 - Advanced Encryption Standard 192 bit
  • AES256 - Advanced Encryption Standard 256 bit

EncryptPassword

Specify the encryption password here.

Confirm Password

Confirm the encryption password by retyping it here.

EngineId

This parameter appears only when 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 this flag to Yes. By default, this parameter is set to No.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Physical Port Number

Indicates the port number of the port for which measurement is taken,

number

This is the physical port number in the network.

Physical port link status

Indicates the current status of network link of current physical port.

 

If the status is down, that means all communication on this port is stopped and controller is not able to communicate with server.

The values reported by this measure and its numeric equivalent are mentioned in the table below:

Measure value Numeric Value
Down 0
Up 1

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the current status of this fan. The graph of this measure, however, represents the status of the fan using the numeric equivalents only .

Physical port link speed

Indicates the current physical link speed of this port.

Gbps

If the speed of the port is too low, there may be some issue with either port or network which needs to be investigated.
