DHCP Option for SNMP Notifications

This proposal suggests a DHCP option for hosts to provide a notification list to DHCP servers during network boot. It aims to notify management stations if the boot process fails in centrally-configured environments. The solution includes an SNMP notification list option and can be considered as a standard DHCP option similar to DNS and NTP.

  2. 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 • Requesting a standard DHCP option • List of hosts (hostname/IP address / UDP port) to notify • Security-model, community or security-name and level • Scope of solution • Includes SNMP notification list option • Does not include other SNMP parameters

  3. Next Steps • Would like DHC to adopt as WG draft • Re-publish as DHC WG draft • Ensure scope of draft is correct • Push to Proposed Standard RFC • Enter WG Last Call as soon as practical • Technical work • Probably include INFORMs as well as TRAPs • Other, based on final scope of draft
