show ha heartbeat counters show ha heartbeat counters Description This command displays statistics for the High Availability extended controller capacity feature. Syntax No parameters. Usage Guidelines The high availability inter-controller heartbeat feature allows for faster AP failover from an active controller to a standby controller, especially in situations where the active controller reboots or loses connectivity to the network. The inter-controller heartbeat feature works independently from the AP mechanism that sends heartbeats from the AP to the controller. If enabled, the inter-controller heartbeat feature supersedes the AP's heartbeat to its controller. As a result, if a standby controller detects missed inter-controller heartbeats from the active controller, it triggers its standby APs to failover to the standby controller, even if those APs have not detected any missed heartbeats between the APs and their active controller. Use this feature with caution in deployments where the active and standby controllers are separated over high-latency WAN links. When this feature is enabled, the standby controller starts sending regular heartbeats to an AP's active controller as soon as the AP has an UP status on the standby controller. By default, the standby controller sends heartbeat messages every 100ms. If the active controller becomes unreachable for the number of heartbeats defined by the heartbeat threshold (by default, 5 missed heartbeats), the standby controller immediately detects this error, and informs the APs using the standby controller to fail over from the active controller to the standby controller . This feature is disabled by default. It can be used in conjunction with the high availability state synchronization feature only in topologies that use a single active and standby controller, or a pair dual-mode active controllers that act as standby controllers for each other. High availability inter-controller heartbeats can be enabled and configured in the high-availability group profile using the WebUI or Command-Line interfaces. Examples The following command displays high-availability heartbeat statistics for the high availability group default. (host) (HA group information "default") #show ha heartbeat counters Heartbeat stats Controller IP Active Reference Count 172.14.0.2 1 Total Heartbeat Sent 101 Total Heartbeat Received 101 Last Missed Heartbeat (Count) Time 0 The output of this command includes the following parameters: Dell Networking W-Series ArubaOS 6.5.x | Reference Guide show ha heartbeat counters | 1510

show ha heartbeat counters

Description

This command displays statistics for the High Availability extended controller capacity feature.

Syntax

No parameters.

Usage Guidelines

The high availability inter-controller heartbeat feature allows for faster AP failover from an active controller to a

standby controller, especially in situations where the active controller reboots or loses connectivity to the

network.

The inter-controller heartbeat feature works independently from the AP mechanism that sends heartbeats

from the AP to the controller. If enabled, the inter-controller heartbeat feature supersedes the AP's heartbeat

to its controller. As a result, if a standby controller detects missed inter-controller heartbeats from the active

controller, it triggers its standby APs to failover to the standby controller,

even if those APs have not detected

any missed heartbeats between the APs and their active controller

. Use this feature with caution in deployments

where the active and standby controllers are separated over high-latency WAN links.

When this feature is enabled, the standby controller starts sending regular heartbeats to an AP's active

controller as soon as the AP has an UP status on the standby controller. By default, the standby controller

sends heartbeat messages every 100ms. If the active controller becomes unreachable for the number of

heartbeats defined by the heartbeat threshold (by default, 5 missed heartbeats), the standby controller

immediately detects this error, and informs the APs using the standby controller to fail over from the active

controller to the standby controller .

This feature is disabled by default. It can be used in conjunction with the high availability state synchronization

feature only in topologies that use a single active and standby controller, or a pair dual-mode active controllers

that act as standby controllers for each other. High availability inter-controller heartbeats can be enabled and

configured in the high-availability group profile using the WebUI or Command-Line interfaces.

Examples

The following command displays high-availability heartbeat statistics for the high availability group

default
