These AP models use their factory-installed certificates for IPsec Internet Protocol security. Some AP model types have factory-installed digital certificates A digital certificate is an electronic document that uses a digital signature to bind a public key with an identity-information such as the name of a person or an organization, address, and so forth. by default, so it is very important that the managed device be able to communicate with the Mobility Master when it is first provisioned. This is performed by means of using public-key self-signed certificates created by each master controller. CPsec is a secure form of communication between a controller and APs to protect the control plane communications. The ArubaOS initial setup wizard enables CPsec Control Plane Security. configuration when you first configure the managed device using the initial setup wizard. You create an initial CPsec Control Plane Security. If a managed device is unable to contact the Mobility Master to obtain it's own certificate, it will not be able to certify the APs, and those APs can not communicate with their managed device until Mobility Master- managed device communication has been re-established.
If the Mobility Master has any associated managed device, the Mobility Master sends a certificate to each managed device, which in turn sends certificates to their own associated APs. The managed device certifies its APs by issuing them certificates. using public-key self-signed certificates created by each Mobility Master. Remote APs are deplyed at branch office sites and are connected to the central network on a WAN link. or remote APs Remote APs extend corporate network to the users working from home or at temporary work sites. Campus APs are deployed as part of the indoor campus solution in enterprise office buildings, warehouses, hospitals, universities, and so on. communications between a managed device and campus APs Campus APs are used in private networks where APs connect over private links (LAN, WLAN, WAN or MPLS) and terminate directly on controllers. IPsec is a protocol suite for secure IP communications that authenticates and encrypts each IP packet in a communication session. ** server can't find .cluster.You are here: Home > Control Plane Security > Control Plane SecurityĪrubaOS supports secure IPsec Internet Protocol security. $ kubectl exec -it dnsutils - nslookup .cluster.local $ kubectl exec -it pod-deployment-65ccfdbf89-ltv5b - hostname Gives the same response $ kubectl exec -it pod-deployment-65ccfdbf89-ltv5b - cat /etc/os-release
