Graceful Restart (GR) allows a router to continue forwarding packets while it restarts its OSPF process. The GR helper role on AOS-CX switches supports routers during this process. OSPFrouters listen for Grace-LSAs to identify neighbors undergoing a graceful restart, maintaining adjacencies with those routers to allow uninterrupted forwarding.

In an Aruba deployment, if an AP's interfaces show different LACP states, it often indicates a configuration mismatch. If one interface is up and the other is blocked as shown in the output,it's likely due to both interfaces on the AP being set to LACP active mode, which is a correct setting for establishing an LACP channel with Aruba switches like the CX 6300 series.

The capture shows messages related to WPA key management, indicating WPA2-PSK is being used. Also, the capture includes a DHCP request from the client but no corresponding DHCP ACK, suggesting the client is not receiving an IP address, which could explain the connectivity failure.

To maximize wired bandwidth utilization, especially when multiple APs are terminating on mobility gateways, it's best practice to aggregate physical ports into a port channel. This provides redundancy and increased bandwidth by combining the throughput of multiple ports.

In the United States, the operation in the 6GHz band for Wi-Fi devices such as the AP-634 and AP-635 is regulated by the Automated Frequency Coordination (AFC) system, which determines the channels that can be used based on the location. Since the Proof of Concept (POC) was conducted in a different location using AP-635 APs, the allowable channels identified by the AFC service for that location would be different than the channels allowed for the actual deployment location of the AP-634 APs. This would result in a different set of broadcasting channels being available for use in the new warehouse deployment.

When cluster preemption is not enabled, access points (APs) will not automatically fail back to the primary gateway cluster once it is up again after having failed over to the secondary. This would result in an equal split of APs across primary and secondary clusters if both clusters are operational. Without preemption, there's no automatic rebalancing of APs back to the primary cluster, leading to the current distribution.

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.
