For each loopback session listed, this information is displayed:
• Header containing the Interface name and session ID, which uniquely identify the local loopback
session,
• Direction which specifies the direction of the loopback,
• Time out – the time out period specified when the loopback was started,
• Time left – the amount of time left until the loopback session is automatically stopped,
• Status – the status of the loopback session,
• Filters – details of the filters specified when the loopback session was started. Similar to the start
CLI, only the filters supported by the platform are displayed.
