394 | Chapter 16. Network Login
NETGEAR 8800 User Manual
Note: If you use 802.1x network login, authenticated clients remain
authenticated during failover; however, shortly after failover, all
authenticated clients automatically re-authenticate themselves.
Re-authentication occurs without user intervention.
If failover occurs during the authentication or re-authentication of a client, the client must
repeat the authentication process.
Note: Before initiating failover, review the section Synchronizing Nodes on
Modular Switches on page 825 to confirm that your switch and both
(or all) nodes are running software that supports the synchronize
command.
To initiate hitless failover on a network that uses network login:
1. Confirm that the nodes are synchronized and have identical software and switch
configurations using the
show switch {detail} command. The output displays the
status of the primary and backup nodes, with the primary node showing
MASTER and the
backup node showing
BACKUP (InSync).
If the primary and backup nodes, are not synchronized and both nodes are running a
version of firmware that supports synchronization, proceed to
step 2.
If the primary and backup nodes, are synchronized, proceed to step 3.
2. If the primary and backup nodes, are not synchronized, use the synchronize command to
replicate all saved images and configurations from the primary to the backup.
After you confirm that the nodes are synchronized, proceed to step 3.
3. If the nodes are synchronized, use the run msm-failover command to initiate failover.
For more detailed information about verifying the status of the nodes and system redundancy,
see
Understanding System Redundancy on page 64. For more information about hitless
failover, see Understanding Hitless Failover Support on page 69.
