The Cisco ISR 1101 platform supports LTE and Wi-Fi capabilities. It is part of the Cisco 1000 Series Integrated Services Routers, which are designed for secure SD-WAN, LTE, and Wi-Fi connectivity.

The BFD value of 8 represents the number of Bidirectional Forwarding Detection (BFD) sessions. BFD is a network protocol used to detect faults between two forwarding engines connected by a link. Each session continuously verifies that the data flow between the network devices is functional. In this context, the value 8 indicates that there are 8 active BFD sessions on the device.

When a WAN edge router connects to the Cisco SD-WAN fabric, it establishes a DTLS or TLS tunnel with the vSmart controller to ensure secure and reliable control plane connections. Additionally, the WAN edge router forms IPsec tunnels with other WAN edge routers to secure the data plane traffic passing between the branches. Hence, DTLS or TLS tunnels are used for control plane communication with controllers like vSmart, while IPsec tunnels are used for data plane communication among WAN edge routers.

The Cisco SD-WAN component used to upload an authorized serial number file when Smart Account Sync is not used is vManage. vManage is the management plane component of Cisco SD-WAN architecture and is responsible for the centralized configuration, management, and monitoring of the SD-WAN environment. It is the component capable of handling tasks such as uploading serial number files for device authorization.

The default port used for vBond under controller certificates, if no alternate port is configured, is 12345. This is a standard port number associated with vBond in Cisco SD-WAN configurations.
