This alternative concerns interface and route operational show-command discipline; its associated risk is: An administratively up interface does not establish that tagging, adjacency or end-to-end forwarding works correctly. The observed case An engineer pastes legacy ArubaOS-Switch syntax into an AOS-CX switch without checking parser differences requires the more specific aos-cx cli configuration context and verification control. The targeted action is: Use the appropriate AOS-CX global, VLAN, interface and routing CLI contexts, and verify commands against the exact platform and version.

This alternative concerns layer 2 protection dhcp snooping and arp inspection; its associated risk is: Untrusted DHCP servers or forged ARP messages can redirect clients or disrupt campus communications.
