Why does a user fail to log in to a stack system of S series switches using the web system

There are two reasons for a failed web system login after S series switches (S1700 excluded) set up a stack system:

1. A stack system of V200R001 or an earlier version does not support the web function. After a stack system is set up, the web function does not take effect and cannot be reconfigured.

2. A stack system of V200R001 or a later version supports the web function. If a standalone device is configured with the web function before joining in a stack system, but fails to become the master device, the web function does not take effect. In this case, you need to reconfigure the web function.
