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.
