An unconfigured LANCOM device boots with an activated DHCP client and uses this to retrieve an IP address, netmask, DNS address, and gateway address from the network's DHCP server.
By means of the vendor-specific DHCP option 43, a suitably configured DHCP server sends information about how to reach an LSR (Large Scale Rollout) server, among other things. The rollout agent of the LANCOM device processes this information, contacts the LSR server and, according to the rollout strategy, it retrieves its configuration, updates its firmware, or whatever is required.
This function simplifies the rollout process as the devices no longer have to be preconfigured. This LSR information can also be compiled from variables, in which case it is possible to operate without a central rollout system (LSR).
The LSR server connects via HTTP, HTTPS or TFTP, in which case an SSL certificate needs to be stored on the LANCOM device to secure the connection.
It remains possible to configure a rollout agent in advance. In this case, the LSR information received by the LANCOM device is sure to contain the current address of the LSR server.
