Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The module role in the stack.
What is rlPhdModuleRole?
This read-only INTEGER reports the role this module plays within a stack: standalone, master, backup, or slave. An admin managing a stack needs to know which unit is currently master, handling management and control-plane duties, versus backup or slave, especially when planning a firmware upgrade or troubleshooting a failover. For example, if the admin sees a module's role change from backup to master, they know the previous master failed or was reset and the backup unit has taken over stack management.
