Summary
• Hosts need notification list from DHCP
– During network boot
• Can’t get information from disk, which isn’t there yet
• Need to notify management station if boot fails
– For centrally-configured environments
• Similar to DNS, NTP, other standard DHCP options
• New DHCP option
– List of hosts (hostname/IP address / UDP port) to notify
– Community or security model, level, and name
• Scope of solution
– SNMP notification list option
– Does not include other SNMP parameters
Next Steps
