Overview

ONTAP CIFS sessions show functionality is used to provide a list of currently established CIFS sessions.

The following lists the fields retrieved using the CIFS sessions GET API:

node.name: Node name hosting this record; basically the node hosting the "server_ip". node.uuid: Node UUID hosting this record; basically the node hosting the "server_ip". svm.name: Svm name to which the "server_ip" belongs to. svm.uuid: Svm uuid to which the "server_ip" belongs to. server_ip: All clients connected to this interface are displayed in rows. client_ip: IP address of the client connected to the interface. identifier: Unique identifier used to represent each SMB session. connection_id: Unique identifier used to represent each SMB Connection. authentication: Type of authentication supported by the server when a client accesses a SMB share. user: Username for the Windows client. mapped_unix_user: Mapped UNIX user name. open_shares: Number of shares opened by the client on a specific SVM. open_files: Number of files opened by the client on a specific SVM. open_others: Number of other files opened by the client on a specific SVM. connected_duration: Time elapsed since the first request was sent by the client for this SMB session. idle_duration: Time elapsed since the last request was sent by the client for this SMB session. protocol: SMB protocol dialects over which the client accesses the SMB share. availability: Level of continuous availabilty of protection provided to the files from the SMB share smb_signing: Specifies whether SMB signing is enabled. smb_encryption: Specifies the SMB session encryption status. large_mtu: Specifies whether the SMB session's large MTU is enabled. connection_count: Counter used to track requests that are sent to the volumes to the node. volumes.name: Name of the active volumes the client is accessing. volumes.uuid: UUID of the active volumes the client is accessing.
