Request parameters

Parameter Type Required Example Description
Action String Yes ModifyAccessRule

The operation that you want to perform.

Set the value to ModifyAccessRule.
AccessGroupName String Yes classic-test

The name of the permission group.
AccessRuleId String Yes 1

The ID of the rule.
SourceCidrIp String Yes 192.1.1.1

The IP address or CIDR block of the authorized object.

You can specify only one IP address or CIDR block for this parameter.

Note If the permission group resides in the classic network, you can specify only one IP address for this parameter.
RWAccessType String No RDWR

Grants access permissions on the file system to the authorized object.

Valid values:

  • RDWR: the default value, which indicates the read and write permissions.
  • RDONLY: the read-only permissions.
UserAccessType String No all_squash

The access permissions for different types of users in the authorized object.

Valid values:

  • no_squash: allows access from root users to the file system.
  • root_squash: grants root users the least permissions as the nobody user.
  • all_squash: grants all users the least permissions as the nobody user.

The nobody user has the least permissions in Linux and can access only the public content of the file system. This ensures the security of the file system.
