What is hmMgmtDiscCfgPrefLen?
This read-write value sets the prefix length, or netmask size, associated with the device's configured management IP address. Admins set it together with hmMgmtDiscCfgIPAddr to correctly define the device's subnet boundaries for management access. For example, an admin configuring a /24 management subnet would set hmMgmtDiscCfgPrefLen to 24 alongside the desired IP address.
