3. Refer to the
History
field to view the current state of the redundancy group.
4. Click
Apply
to save any changes to the screen. Navigating away from the screen without clicking the
Apply button results in all the changes on the screen being discarded.
5. Click the
Revert
button to undo the changes to the screen and revert to the last saved configuration.
5.4.1 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.
Hold Time
Define the
Hold Time
for a redundancy group. If there are no heartbeats received from a
peer during the hold time, the peer is considered to be down. In general, the hold period is
configured for three times the heartbeat period. Meaning, if three consecutive heartbeats
are not received from the peer, the peer is assumed down and unreachable. The hold time is
required to be greater than the heartbeat interval.
Handle STP
convergence
Select the
Handle STP convergence
checkbox to enable STP convergence for the switch.
STP stands for Spanning Tree Protocol. In general, this protocol is enabled in layer 2
networks to prevent network looping. If the network is enabled for STP to prevent looping,
the network forward is 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
execution is important to load balance Access Ports at startup.
Revert Now
Click the
Revert Now
button to immediately revert back to the previous version of the
redundancy configuration. Clicking this button disregards any interval that may have been
set using the Auto Revert In feature. If you have made extensive changes, and then change
your mind about them, you can get rid of them by reading in the previous version of the file.
State
Displays the new state (status) of the redundancy group after a Trigger event has occurred.
Time
Displays the Timestamp (time zone specific) when the state change occurred.
Trigger
Displays the event causing the redundancy group state change on the switch.
Description
Displays a redundancy event description defining the redundancy group state change on the
switch. Typical states include Redundancy Disabled or Redundancy Enabled.
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.
