DHC Working Group Meeting Minutes - 8/98 (Chicago)
(Back to dhcp.org home)
The WG met twice on 8/24. Several issues were discussed in the morning
session. DHCP authentication and the web proxy server option were
discussed in the afternoon session. The morning session included the
following topics; any WG action associated with each topic is included with
the topic summary:
- Relay options draft, Mike Patrick (Motorola): summary of changes to option
spec based on input from WG; WG agreed to WG last call and submit this option
for Proposed Standard status
- DHCP in cable modem nets, Poornima Lalwaney (General Instruments): described
use of DHCP in both RF and telco return cable systems, asked that WG consider
additional DHCP functions to support cable modem operation: server MIB, 3rd
party query, relay agent information option; WG asked that the proposed
use of
DHCP be published as an I-D
- VAMAC agent sub-option, Burcak Beser (3Com): described proposed sub-option
to relay agent information option for "virtual agent" operation; WG asked
that
the proposed sub-option be published as an I-D; WG also asked that Beser and
Lalwaney consider merging their proposals into a single document
- New process for allocating option numbers, Ralph Droms (Bucknell): reviewed
modified process published in ; WG asked
process be modified so option number is assigned when RFC for new option
is published; WG agreed to WG last call after editorial changes and submit
this option for Informational status (to be merged into RFC2132 when DHCP
goes to Standard status)
- Host systems characteristics options, Mike Henry (Intel): reviewed changes
to host systems characteristics options and changes to WFM spec that
accommodate use of existing options, and asked that the WG change the 'client
identifier' option to be a globally unique identifier; WG agreed to change,
and agreed to publish host systems characteristics options as Informational,
with limitation on use of these options to 6 years; WG asked that
relevant text from WFM docs be extracted into I-D for DHC WG
- DHCP futures panel, Mike Carney (Sun): reported that there is a new draft of
recommendations from the futures panel
- DHCP autoconfiguration control, Ryan Troll (CMU): reviewed a proposal for
a draft of an option that controls use of autop-configuration by DHCP
hosts; WG agreed to WG last call four weeks after revised draft published and
submit for Proposed Standard status
- DHCP MIB, Glenn Waters (BayNetworks): announced that new server MIB would
be available in two weeks
- There was an expression of interest in development of DHCP schema, with
the
suggestion for an interim meeting to work on convergence of the several (3?)
outstanding proposals
- User authentication server option, Steve Drach (Sun): described
option to provide URL of NC authentication server; WG agreed to go to WG last
call 4 weeks after publication of revised draft and submit option for
Propsoed Standard
- Safe failover protocol, Bernie Volz (Process): described protocol resulting
from merger of failover and safe failover I-Ds
In the afternoon session, Ralph Droms reviewed the minutes from the interim
meeting on DHC authentication from June. Bill Arbaugh described the
Schiller/Huitema/Droms/Arbaugh (SHDA) protocol, which performs "delayed
authentication" based on discussion at the interim meeting. The outcome of
the interim working group was to recommend the SHDA and Patel protocols to
the WG. The WG agreed to select the SHDA protocol for future development.
Finally, Josh Cohen (Microsoft) described the web proxy server option.
There was discussion of the advisability of combining this option with the
authentication server option in a general purpose "typed URL option". The
WG came to consensus that the two options should be left separate and the
URL option should be considered for the expanded option space (recommended
by the futures panel). The WG acknowledged that the current options space
is nearly exhausted; Mike Carney agreed to investigate recovering some of
the option space in 128-254 and Ralph Droms agreed to try to recover
previously assigned options that have not been used.
