When stacking is enabled on an HPE 3800 switch, the procedures for configuring specific switch ports are the same as for 3800 switches without stacking enabled. However, the port designations for the ports in the stack are modified. That is, each port is identified by its switch’s stack member ID followed by a slash and then the port number, as it is shown on the switch. For example, for a switch with stack member ID 3, port 10 on that switch is identified as port 3/10 for CLI command input and output. Entering a CLI command on a 3800 switch configured for stacking without using the modified port designation results in the message ”Module not present for port or invalid port”.
