A client connecting to a tunneled open network is receiving the wrong VLAN Your customer has a gateway and has sent over a packet capture from a switch port mirror taken from the upstream switch with a packet capture from the IPsec tunnel and the GRE tunnel to help Identify the VLAN being sent from the controller to the AP.
Where will you see the VLAN assignment?
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.
Refer to the CLI output below:
What statement about the output above is correct?
The CLI output indicates a tunnel creation process, where 'SW hw tun created' refers to the switch hardware tunnel being created. The line mentioning 'BYP-10.10.10.101 -> SW hw tun created to 10.10.10.151 tunnel 15.' implies that a tunnel was established to the secondary tunnel endpoint with the IP address 10.10.10.151. This is a common configuration for User-Based Tunneling (UBT) setups where traffic is tunneled to a specific endpoint.
Exhibit.
An engineer has applied the above configuration to R1 and R2 However the routers OSPF adjacency never progresses past the "EXSTART-DR" slate as shown below.
Which configuration action on either router will allow R1 and R2 to progress past the "EXSTART/DR" state?
In OSPF, the 'EXSTART/DR' state indicates that the routers are trying to establish an adjacency but are unable to progress. This can happen if the OSPF network type is incorrectly configured for the type of connection between the routers. Given that R1 and R2 are connected via a point-to-point link (as suggested by the /31 subnet), setting the network type to point-to-point on both routers will remove the need for DR/BDR election, which is unnecessary on a point-to-point link, and allow OSPF to progress past the 'EXSTART' state and form a full adjacency.
Which command would allow you to verity receipt of a CoA message on an AOS 10 GW?
The Change of Authorization (CoA) messages are used in network access control scenarios and are typically received by the network access server, in this case, an Aruba AOS 10 Gateway. The correct command to verify the receipt of a CoA message is related to the control path traffic because CoA is a control plane function.
Option B, packet-capture controlpath udp 3799, is the correct answer because it specifies capturing control plane traffic on UDP port 3799, which is the standard port for CoA messages.
Options A, C, and D are incorrect because:
Option A captures data plane traffic, not control plane traffic.
Option C's packet-capture interprocess udp 3799 does not refer to a standard command for capturing CoA messages.
Option D, tcpdump host-port 3799, does not specify the correct syntax for capturing traffic on Aruba devices.
A university owns a campus with several buildings segmented into east and west wings, which are L3 separated. The east wing has 1600 APs. and the west wing has 1200 Aps. Each wing has a single gateway cluster managed by HPE Aruba Networking Central. Each cluster contains one 7210 mobility gateway The gateways are configured with DHCP relay and route all client VLANs. A new business-critical faculty real-time application requires users to roam within wings but not across wings without disconnections or delay increments.
Which changes must the network administrator make lo successfully meet the requirement without performance degradation matching best practices? (Select two.)
To support a business-critical faculty real-time application that requires seamless roaming within wings without cross-wing roaming, it's essential to ensure high availability and sufficient capacity. Adding an additional 7210 mobility gateway to each cluster would provide the required redundancy and capacity. Running L2 for all SSIDs and permitting user VLANs on gateway uplinks would facilitate the necessary traffic flow without L3 segmentation issues, thus supporting seamless roaming within each wing.
