IP assign tool
• IPassign is a basic tool to detect and configure remotely ICEPAP
MASTERs on the network, even if they have wrong IP configuration.
• i. e. IP address associated to other Beam Line, where ICEPAP came from.
• Automatically
detects ICEPAP
MASTERs on the
network
• Configures the
hostname validated
with DNS
• Writes in flash
memory the
configuration
• Remote reboot

advanced mode of configuration
• This mode allows specialists do what they want ...
• Information:
• MAC
• Configuration:
• hostname
• IP
• mask
• gateway
• BC
• Writes:
• flash
• RAM
• Remote reboot

advanced mode of configuration
• In case of error, the IP connectivity will not
exist, so IPassign must be used again to
reconfigure ICEPAP Master with good
values.

design review
• IPassign tool is supported on multicast protocol
• HW filtering with a reserved virtual MAC address for multicast packages, and IP filtering
for multicast class D address.
• class D address (224.0.0.0 – 239.255.255.255), reserved virtual MAC
(01:00:5e:xx:xx:xx)
• receiver can have wrong IP data (IP addr, gateway, mask ...)
• UDP
• A listener program must be running in ICEPAP MASTER, which is
launched at boot time.
• Bidirectional and errorless communication was implemented by in-house
developed protocol with:
• destination / source ID
• package numbering
• function code
• CRC

conclusions
IPassign tool and listener program for ICEPAP module were
developed and tested.
Connectivity was restricted to a Beam Line (TTL=1).
Structure and protocol created can be extended to use in
other tasks where simultaneous communication with a group
of receivers is needed, i. e. upgrading package files.
