Troubleshooting Switch Connectivity Issues

The following tests are available to diagnose issues related to wired network connections:

Ping Test

Sends ICMPInternet Control Message Protocol. ICMP is an error reporting protocol. It is used by network devices such as routers, to send error messages and operational information to the source IP address when network problems prevent delivery of IP packets. echo packets to the IP address of the selected switch to check for latency issues.

To perform a ping test on switches, complete the following procedure:

1. In the Network Operations app, select one of the following options:
   • To select a group, label, site, or all devices in the filter, set the filter to one of the options under Groups, Labels, or Sites. For all devices, set the filter to Global.

     The dashboard context for the selected filter is displayed.

   • To select a switch in the filter:
     1. Set the filter to Global.
     2. Under Manage, click Devices > Switches.

        A list of switches is displayed in the List view.

     3. Click a switch under Device Name for which you want to perform diagnostic test.

        The dashboard context for the switch is displayed.

2. Under Analyze > Tools, click Network Check.
3. From the Device Type drop-down, select Switch.
4. From the Test drop-down, select Ping Test.
5. From the Sources drop-down, select source(s). You can select multiple switches.

   You can select Aruba Switch or Mobility Access Switch from the Sources drop-down.

6. From the Destination Type drop-down, select one of the following:
   • Hostname/IP Address—Enter the hostname or IP address in the Hostname/IP Address field.
   • Client—Select a client from the Client drop-down.

7. To use additional parameters, click Show Additional Test Settings and enter values in the following fields:

   Show Additional Test Settings is not displayed when a Test type is not selected.

   1. In the Repetitions field, enter the repetition value. The value should be between 1 to 500.
   2. In the Data Size field, enter the data size. The value should be between 0 to 65399.

   Mobility Access Switches do not support repetition and data size.

8. Select the Use Management Interface option if you want to use VRFVisualRF. VRF is an AirWave Management Platform (AMP) module that provides a real-time, network-wide views of your entire Radio Frequency environment along with floor plan editing capabilities. VRF also includes overlays on client health to help diagnose issues related to clients, floor plan, or a specific location. Management interface. To use VRF Default interface, clear this option, which is the default.

   Use Management Interface option is available only for AOS-CX switches.

9. Click Run. The test output is displayed in the Device Output section.
   

Traceroute

Tracks the packets routed from a network host.

To perform a traceroute test on switches, complete the following procedure:

   • To select a group, label, site, or all devices in the filter, set the filter to one of the options under Group, Label, or Site. For all devices, set the filter to Global.

     The dashboard context for the selected filter is displayed.

   • To select a switch in the filter:
     1. Set the filter to Global.
     2. Under Manage, click Devices > Switches.

        A list of switches is displayed in the List view.

     3. Click a switch under Device Name for which you want to perform diagnostic test.

        The dashboard context for the switch is displayed.

2. Under Analyze > Tools, Network Check.
3. From the Device Type drop-down, select Switch.
4. From the Test drop-down list, select Traceroute.
5. From the Sources drop-down, select source(s). You can select multiple switches.
6. Enter the hostname or IP address in the Hostname/IP Address field.
7. To use additional parameters, click Show Additional Test Settings, and select the Use Management Interface option, if you want to use the VRF Management interface. To use the VRF Default interface, clear this option.

   Show Additional Test Settings is disabled when no Test type is selected.
