In a packet capture from an upstream switch port mirror, you would see the VLAN assignment. The port mirror captures the traffic as it is on the network, including any VLAN tags. GRE or IPsec tunnels encapsulate the original packet, including VLAN tags, but the VLAN information is not visible within the encapsulation headers.

The CLI output displays EVPN routes and their corresponding next hops. The "Route Distinguisher" entries followed by IP addresses in the 172.21.11.x range indicate these are loopback addresses used by the underlay network. The underlay network provides the basic routing and forwarding plane for the overlay network that EVPN is part of. These loopback addresses are crucial for the proper functioning of the EVPN control plane.

In HPE Aruba Networking User Experience Insight (UXI), when a sensor performs continuous network and application testing, it generates packet captures as part of the diagnostic information available for download from the UXI dashboard. These captures are packaged into a compressed (.zip) file that typically contains multiple .pcap files categorized by test results and test types.

According to the Aruba UXI operational documentation, the sensor separates captured test traffic based on success or failure results for clarity and troubleshooting efficiency. The “datagrams.pcap” file includes only packet captures of successful tests that completed as expected, while the “datagrams-failed.pcap” file contains captures for failed or incomplete tests.

Therefore, if you review only the datagrams.pcap file, you will see data from tests that passed successfully and will not find the failed attempts that may reveal connectivity or performance problems. To analyze failure-related issues (for instance, packet loss, authentication failures, or latency problems), it is necessary to examine the “datagrams-failed.pcap” file included in the same downloaded archive.

This behavior ensures a logical separation between functioning and problematic test sessions and allows engineers to focus analysis on the most relevant captures without confusion between successful and failed transactions.
