Parameter lms-ipv6 lms-ping-interval lms-preemption maintenancemode Description Range In multi-controller ipv6 - networks, specifies the IPv6 address of the local management switch (LMS)- the controller-which is responsible for terminating user traffic from the APs, and processing and forwarding the traffic to the wired network. This can be the IP address of the local or master controller. When using redundant controllers as the LMS, set this parameter to be the VRRP IP address to ensure that APs always have an active IP address with which to terminate sessions. Default - Specifies the interval at which application level ping needs to be sent to primary controller to check the reachability. Applicable only for RAP. NOTE: If this parameter is changed, UDP session timeout on an intermediate router which performs NATing should be set accordingly. The preferred timeout value is (lms-ping-interval + 30sec). 10-60 seconds 20 seconds Automatically reverts to the - primary LMS IP address when it becomes available. disabled Enable or disable AP maintenance mode. This setting is useful when deploying, maintaining, or upgrading the network. If enabled, APs stop flooding unnecessary traps and syslog messages to network management systems or network operations centers when deploying, maintaining, or upgrading the network. The controller still generates debug syslog messages if debug logging is enabled. disabled 217| ap system-profile Dell Networking W-Series ArubaOS 6.5.x | Reference Guide
