POST can be viewed by which method on the OS9700 switch?

• A. Connecting a network management laptop to the console port of the active Chassis Management Module (CMM).
• B. Through the management VLAN interface.
• C. Via SNMP.
• D. Through the switch's web GUI.

Answer: (A)

During boot, POST output is shown on a console connection. On the OS9700, you view that output by connecting a laptop through a serial cable to the active Chassis Management Module’s console port. This gives you the real-time boot progress and POST status as the system initializes.

The other management paths—through the management VLAN interface, SNMP, or the switch’s web GUI—come up only after the device is up and its OS is running, so they won’t display POST messages. In a chassis with redundant CMMs, you specifically connect to the active CMM to see the boot and POST output.
