In the context of ArubaOS-CX, particularly with the 6300 series switches, setting the MTU on a routed

Link Aggregation Group (LAG) interface requires the interface lag id command in the configuration,

specifying the LAG interface you're configuring. The ip mtu command is then used to set the desired

MTU size for that LAG. Option A correctly shows this configuration process, where the MTU is set to

9198 for the LAG interface, in line with the requirements for routing larger frames, which could be

necessary for certain applications or data flows that require jumbo frames.

The information related to the configuration of Aruba switches is consistent with the principles and

guidelines found in the technical documentation for the ArubaOS-CX 6300 series switches, which

emphasizes the importance of correct MTU settings for network performance and stability.
