Ethernet Link Aggregation Test
Link aggregation enables one or more network links to be aggregated together to form a link aggregation group. When network links are aggregated, more bandwidth resources become available to the network and load on the network can be uniformly distributed across the links. If one/more links in a group go down, it may limit the bandwidth resources available to the group and may even overload a few other links in the group. To avoid this, administrators must continuously track the state of every link within every aggregation group that is configured. This is where the Ethernet Link Aggregation test helps! This test periodically checks the status of each link aggregated within every link aggregation group and instantly alerts administrators when a link goes down or is in an unknown state. This way, the test enables administrators to ensure that all links in an aggregate group are available at all times for providing bandwidth resources and handling the network load.
Target of the test : A Solaris virtual server
Agent deploying the test : An internal agent
Outputs of the test : One set of results for each link in each link aggregation group
Parameter | Description |
---|---|
Test period |
How often should the test be executed |
Host |
The host for which the test is to be configured. |
Port |
The port number at which the specified host listens. By default, the port is NULL. |
Connect Using |
By default, this parameter is set to sudo. This indicates that, by default, this test uses the sudo command to connect to the Solaris virtual server and pull out metrics. If you want the test to use the pfexec command instead, select the pfexec option from the Connect Using drop-down. |
Detailed Diagnosis |
To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

Measurement | Description | Measurement Unit | Interpretation | ||||||||
---|---|---|---|---|---|---|---|---|---|---|---|
Link aggregation status |
Indicates the current status of this link within this link aggregation group. |

The values that this measure can report and their corresponding numeric values are listed in the table below:
Note: By default, this measure reports the Measure Values in the table above to indicate link status. In the graph of this measure however, the same is represented using the corresponding numeric equivalents only. The detailed diagnosis of this test reveals the speed, operational state, and duplex state of a link. |
