force-configured-state Forces adopted APs to auto revert when a failed wireless controller or service platform (in a cluster) restarts
When an active controller (wireless controller, or service platform) fails, a standby controller in the cluster
takes over APs adopted by the failed active controller. If the failed active controller were to restart, it starts a
timer based on the ‘force-configured-state-delay’ interval specified. At the expiration of this interval, the
standby controller releases all adopted APs and goes back to a monitoring mode. If the active controller
fails during this interval, the ‘force-configured-state-delay’ timer is stopped. The timer restarts as soon as
the active controller comes back up.
This feature is disabled by default.
force-configured-state-dela
y <3-1800> Forces cluster transition to the configured state after a specified interval
•
<3-1800> – Specify a delay from 3 - 1800 minutes. The default is 5 minutes.
This is the interval a standby controller waits before releasing adopted APs, when a failed active controller
becomes active again.
handle-stp Enables/disables Spanning Tree Protocol (STP) convergence handling. This feature is disabled by default.
In layer 2 networks, this protocol is enabled to prevent network looping. If enabled, the network forwards
data only after STP convergence. Enabling STP convergence delays the redundancy state machine
execution until the STP convergence is completed (the standard protocol value for STP convergence is 50
seconds). Delaying the state machine is important to load balance APs at startup.
master-priority
<1-255> Configures cluster master priority
•
<1-255> – Specifies cluster master election priority. Assign a value from 1 - 255. Higher the value
higher is the precedence. The default is 128.
In a cluster environment, one device from the cluster is elected as the cluster master. A device’s master
priority value decides the device’s priority to become cluster master.
member Adds a member to the cluster. It also configures the cluster VLAN where members can be reached.
ip <IP> level [1|2] Adds IP address of the new cluster member
•
<IP> – Specify the IP address.
•
level – Optional. Configures routing level for the new member. Select one of the
following routing levels:
•
1 – Level 1, local routing
•
2 – Level 2, In-site routing
vlan <1-4094> Configures the cluster VLAN where members can be reached
•
<1-4094> – Specify the VLAN ID from 1- 4094.
