What is the LSM DHCP IP Service Range? When/how are LSM DHCP IP Service Range IP addresses used?
•The range of contiguous IP addresses that will be managed exclusively by LSM
•A Machine is assigned a LSM DHCP IP Service Range IP address when its Service State is set to NetbootReady (waiting for a PXE boot to begin service) and the IP address is used while the Machine is being serviced
•If a Machine stays in a powered-on state after servicing and is set to DHCP with no other DHCP service present, it will consume a Service IP until it is powered off
How do I decide how many IP addresses to have in my LSM DHCP IP Service Range? 4-5 or more?
The number of IP addresses in LSM DHCP IP Service Range determines the maximum simultaneous number of Machines awaiting service or being serviced by LSM. Machines may also reside within the LSM DHCP IP Service Range when not being serviced by LSM.
Your LSM DHCP IP Service Range
•Must have between 4 (or 5) and 254 contiguous IP addresses (2 of which are reserved for the LSM Server) on a valid subnet, up to a /24 (.0-.255) Subnet.
•The IP address of the LSM Server can be inside or outside the LSM DHCP IP Service Range
•Should be on a subnet where the Machines to be serviced by LSM reside, otherwise the User must implement PXE forwarding
•Will service PXE requests forwarded by Machines to the IP address of the LSM Server
•Will manage DHCP IP address assignments within the LSM DHCP IP Service Range. Refer to DHCP Considerations if you have existing DHCP servicing the subnet.
The LSM DHCP IP Service Range can be a complete /24 subnet of 254 IPs or any subset of contiguous IPs in a subnet consisting of 4 IPs or more.
In this User Guide, most examples will come from a 192.168.49.0 network.
LSM DHCP IP Service Range Technical Overview
LSM provides a custom DHCP service with IP assignment within a designated LSM DHCP IP Service Range of IPs for LSM PXE response and LSM service processing.
LSM PXE Service is defined as the service process from initial PXE request through LSM service completion. During this service cycle LSM DHCP provides a service IP for the initial PXE request and the same IP for all subsequent DHCP requests made during the process.
Existing and new dedicated IPs in the designated LSM IP range can be registered to maintain these IPs in LSM range and exclude these IPs from LSM PXE Service rotation use. Once registered these Machines may also be scheduled for and receive LSM PXE service via their LSM DHCP static IP.
The LSM DHCP can be the only DHCP service on its subnet or can coexist with other DHCP services that are configured to exclude the LSM DHCP IP Service Range.
