An ArubaOS-CX is \ssmq DCBX on Interface 1/1/1. You enter this command:
show dcbx interface 1/1/1
Is this where you can see whether the connected converged network adapter (CNA) has accepted the application priorities advertised with DCBX?
Solution: in the Enhanced Transmission Selection (ETS) Local advertisement section

You plan to use multi-protocol BGP to implement dynamic VRF route leaking on an ArubaOS-CX switch.
Is this a rule for the setup?
Solution: You cannot leak multicast routes.

Is this part of a valid strategy for load sharing traffic across the links in an Ethernet Ring Protection Switching (ERPS) ring?
Solution: Implement Virtual Switching Extension (VSX) on pairs of ERPS switches at the same site. Then combine multiple links between two data centers into VSX LAGs (M-LAGs).

Is this how you should position switches in the ArubaOS-CX portfolio tor data center networks?
Solution: Deploy Aruba 83xx switches as data center leaf switches.

You ate using NetEdit to manage AruDaOS-CX switches. You want to deploy a standard conflg to the switches, but need the config to include a few device-specific settings such as hostname and IP address.
Is this what you should do?
Solution: Instead of using a standard configuration plan to deploy the configuration, create an auto config plan that uses scripts.
