Configuring Network Login
ExtremeWare XOS 11.3 Concepts Guide

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.
To initiate hitless MSM failover on a network that uses network login:
1 Confirm that the MSMs are synchronized and have identical software and switch configurations
using the
show switch {detail}
command. The output displays the status of the MSMs, with the
primary MSM showing
MASTER
and the backup MSM showing
BACKUP (InSync)
.
If the MSMs are not synchronized, proceed to step 2 .
If the MSMs are synchronized, proceed to step 3 .
2 If the MSMs are not in sync, replicate all saved images and configurations from the primary to the
backup using the
synchronize
command.
3 Initiate failover using the
run msm-failover
command.
For more detailed information about verifying the status of the MSMs and system redundancy, see
“Understanding System Redundancy with Dual MSMs Installed—Modular Switches Only” on page 70 .
For more information about hitless failover, see “Understanding Hitless Failover Support—Modular
Switches Only” on page 74 .
