The MIB's DESCRIPTION for cucsLicenseFileFsmRmtErrDescr is only the auto-generated stub 'Cisco UCS license:FileFsm:rmtErrDescr managed object property', but the 'rmtErrDescr' property name together with its SnmpAdminString type tell us this column, on the finite-state-machine record that tracks a license file's install/validation workflow, holds the rmtErrDescr as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). The rmtErrDescr is the text explanation that accompanies rmtErrCode, spelling out in words what the remote peer reported wrong with the finite-state-machine record that tracks a license file's install/validation workflow's operation, rather than leaving the admin to decode a bare error number. If the peer fabric interconnect couldn't reach the license server it might populate this with something like 'connection to peer failed'.
