Switch > VSX

Aruba Virtual Switching Extension (VSX) is virtualization technology for aggregation and core AOS-CX switches. The VSX solution lets the switches present as one virtualized switch in critical areas.

VSX is supported in the AOS-CX 6400, AOS-CX 8320, and AOS-CX 8325 Switch Series.

Aruba Central provides support for VSX by displaying information about the configurations of the switches and the status of the inter-switch link (ISL) between the switches.

Viewing the VSX Page

To navigate to the VSX page in the Switch dashboard, complete the following steps:

1. In the Network Operations app, set the filter to one of the options under Group, Label, or Site. Ensure that the filter selection contains at least one AOS-CX switch. For all devices, set the filter to Global.

   The dashboard context for the selected filter is displayed.

2. Under Manage, click Devices > Switches.

   A list of switches is displayed in the List view.

3. Click an AOS-CX switch under Device Name.

   The dashboard context for the switch is displayed.

4. Under Manage, click VSX.

   The VSX page displays the following details:

   • Switch > VSX
   • Info
   • Actions
5. To exit the switch dashboard, click the back arrow on the filter.

VSX Summary

Displays state information of the switch, connections to the peer switch, and the role of the switch in the VSX configuration.

Table 1: VSX Summary Details

Field	Description
ISL State	State of the ISL connection with the peer AOS-CX switch. Following are the supported values: WAITING_FOR_PEER—Waiting for connectivity to the peer. PEER_ESTABLISHED—Steady state. VSX LAGs are up when the device is in this state. SPLIT_SYSTEM_PRIMARY—Lost ISL connectivity to the peer and the device is operating as primary. SPLIT_SYSTEM_SECONDARY—Lost ISL connectivity to the peer and the device is operating as secondary. SYNC_PRIMARY—ISL connectivity to the peer restored and the device is syncing states to the peer. SYNC_SECONDARY—ISL connectivity to the peer restored and he device is learning states from the peer. VSX LAGs are down when the device is in this state. SYNC_SECONDARY_LINKUP_DELAY—Device has learned its states from the peer and monitoring for hardware is to be programmed. VSX LAGs are down when the device is in this state.
ISL Mgmt State	Management state of the ISL. Following are the supported values: OPERATIONAL—ISL management is operational. INTER_SWITCH_LINK_MGMT_INIT—ISL management is in initialization state. CONFLICTING_OR_MISSING_DEVICE_ROLES—Either the role is missing on one of the VSX peers or the same role is configured on both VSX peers. SW_IMAGE_VERSION_MISMATCH_ERROR—Software version on the primary device does not match with the software version on the secondary device. INTER_SWITCH_LINK_DOWN—ISL is down. INTERNAL_ERROR—ISL management has internal errors.
Config Sync Status	Status of the configuration synchronization between the VSX switches. Following are the supported values: IN-SYNC—Configuration synchronization is operational and the VSX switches are in sync. DISABLED—Configuration synchronization is disabled. SW_IMAGE_VERSION_MISMATCH_ERROR—Software image version on the primary device does not match with the software image version on the secondary device. CONFLICTING_OR_MISSING_DEVICE_ROLES—Either the role is missing on one of the VSX peers or the same role is configured on both VSX peers. PEER_DB_CONNECTION_ERROR—Error in connecting to peer database. It involves errors due to ISL or ISL management. CONFIGURATION_SYNC_CONFLICT—Configuration synchronization is operational but has conflicts synchronizing the configuration. Conflicts can occur if the configuration on the primary device is marked for sync, but the same configuration on the secondary device is not marked for sync. CONFIGURATION_SYNC_MISSING_REFERENCE—Configuration synchronization is operational but has missing references in synchronizing the configuration.
NAE	Status of the NAE connection between the VSX switches.
HTTPS Server	Status of the HTTPSHypertext Transfer Protocol Secure. HTTPS is a variant of the HTTP that adds a layer of security on the data in transit through a secure socket layer or transport layer security protocol connection. server connection between the VSX switches.
Last Synched	Timestamp of when the configuration was synched between the peer switch. NOTE: Last synced data is displayed in the Switch > VSX page only when VSX synchronization is enabled for the AOS-CX switch. However, enabling VSX synchronization using template configuration in Aruba Central is not recommended. By enabling VSX synchronization, the peer switch may get into an unknown configuration state.
Role	Role of the AOS-CX switch in the VSX configuration. Supported values are Primary and Secondary

Info

Displays system and configuration information of the switch and its peer. The following details are displayed:

• System
  • Local MAC—MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address of the selected switch.
  • Peer MAC—MAC address of the peer switch.
  • Peer Hostname—Hostname of the peer switch.
  • Peer IP—IPv4 address of the peer switch.
• Configuration
  • Config Sync—Indicates whether the configuration synchronization between the peers are enabled or disabled.
  • ISL Port—Inter-switch Link (ISL) port number of the selected AOS-CX switch. If the ISL is a LAGLink Aggregation Group . A LAG combines a number of physical ports together to make a single high-bandwidth data path. LAGs can connect two switches to provide a higher-bandwidth connection to a public network. , then this field displays the LAG name.
  • Peer ISL Port—ISL port number of the peer switch. If the ISL is a LAG, then this field displays the LAG name.
  • MC LAGs—List of MC LAG names present in the switches.

Actions

The Actions tab displays the various options available for remote administration of the switch. The following options are available:

• Reboot—Reboots the switch. See Rebooting Switches.
• Tech Support—Allows the administrators to generate a tech support dump for troubleshooting the device. See Troubleshooting Aruba Switches.
• Console—Opens the remote console for a CLI session through SSHSecure Shell. SSH is a network protocol that provides secure access to a remote device. . Ensure that you allow SSH over port 443. The default user ID is admin, but you can edit and customize the user ID. This custom user ID must be mapped to the device. See Opening Remote Console for Switch.
