Accesspoint Group Throughputs Test

The Peplink WAN router is associated with multiple access points to serve a large number of WAN users. To manage the access points and simplify the load distribution among the users, administrators create access point groups. By default, the target router is automatically created with a default access point group which can have up to 16 access points. However, administrators can create multiple access point groups using the web admin interface. Using the access point groups so created, administrators can easily share the load among the users and manage the access points without any hassles. Administrators may also wish to calculate the throughput of the access point groups to find out how well/badly the access point groups handle the network traffic in the environment. Poor traffic handling by the access point groups may result in low throughput which indicates bursty network traffic in the environment. This in turn can cause WAN users to experience slowness when interacting through the router. To prevent such eventualities, it is important for the administrators to check the throughput of the access point groups at regular intervals. For this purpose, administrators can use the Accesspoint Groups Throughputs test!

This test auto-discovers the access point groups, and reports the amount of data sent and received and the number of packets transmitted and received by each access point group. Using this test, administrators can easily identify the access point group that handled the higher level of traffic to the router.

Target of the test : A Peplink WAN Router

Agent deploying the test : An external agent

Outputs of the test : One set of results for each access point group created on the target router.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the host for which this test is to be configured.

SNMPPort

The port at which the monitored target exposes its SNMP MIB; The default value is 161.

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.

SNMPCommunity

The SNMP community name that the test uses to communicate with the target router. This parameter is specific to SNMP v1 and v2 only. Therefore, if the SNMPVersion chosen is v3, then this parameter will not appear.

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. 

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.

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

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 this 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
  • AES – Advanced Encryption Standard

EncryptPassword

Specify the encryption password here.

Confirm Password

Confirm the encryption password by retyping it here.

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.

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.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Data Transmitted

Indicates the rate at which the data was transmitted from this access point group.

Bytes/sec

Comparing the values of these measures will reveal the access point group that transmitted/received the maximum amount of data.

 

Data received

Indicates the rate at which the data was received by this access point group.

Bytes/sec

Packets transmitted

Indicates the number of packets transmitted from this access point group.

Packets

Compare the values of these measures to identify the access point group that transmitted/received the maximum number of packets.

 

Packets Received

Indicates the number of packets received by this access point group.
