Switch Services 5-39
5.4.2 Reviewing Redundancy Status
The switch is capable of displaying the status of the collective membership of the cluster. Use this
information to assess the overall health and performance of the group.
To configure switch redundancy memberships:
1. Select Services > Redundancy from the main menu tree.
The Redundancy screen displays with the Configuration tab selected.
2. Select the Status tab.
3. Refer to the Status field to assess the current state of the redundancy group.
NOTE: When ETH2 of one of the group members is unplugged, the other members report
that this member as gone, but an AP will continue to be adopted by the switch with no
ETH2 connectivity.
Protocol Version The Cluster Protocol should be set to an identical value for each switch in the
redundancy group. The protocol version is one of the parameters used to
determine whether two peers can form a group.
Redundancy state is Displays the state of the redundancy group. When the redundancy feature is
disabled, the state is “Disabled.” When enabled, it goes to a “Startup” state. From
“Startup” it goes to a “Discovery” state immediately if the STP convergence is not
enabled. Otherwise, it remains in “Startup” for a period of 50 seconds (the
standard STP convergence time). During the discover state, the switch exchanges
heartbeats and update messages to discover other members and define the
redundancy group license. After discerning memberships, it moves to an Active
state. There is no difference in state execution for Primary and Standby modes.
AP Licenses in Group Displays the number of Access Ports that can be adopted in the redundancy group.
This value is calculated when a member starts-up, is added, is deleted or a license
changes (downgrade and upgrade.) This value is equal to the highest license level
of its members. It is NOT the sum of the license level of its members. For
information on licensing rules impacting redundancy group members, see
Redundancy Group License Aggregation Rules on page 5-46.
