- This is only a rough draft - Megan 04/16/92
-
- Minutes
- RMON Working Group
- 23rd IETF
- San Diego
-
- The RMON WG met in two formal sessions during the San Diego
- IETF meeting. Issues from both RFC 1271 and the developing
- Token Ring MIB were discussed. What follows is an encapsu-
- lation of the discussions
- Interoperability Interoperation between two or more indepen-
- dent implementations is a requirement for an RFC to become a
- full Internet standard (RFC 1310). Accordingly, Mike
- Erlinger and Steve Waldbusser discussed their attempt to
- organize two interoperability testing sessions for Ethernet
- RMON probes and managers.
-
- 1. Week of May 25th (after InterOp) at CMU in Pitts-
- burgh
- 2. Week of Jul 20th (after IETF) at Frontier Software
- in Boston
- It was noted that these interoperability activities
- were being organized outside of the auspices of the
- IETF and that Mike and Steve were reporting on their
- progress as part of the IETF WG meeting.
-
- The first draft of a token ring RMON MIB was created about
- 6-weeks prior to the IETF at a WG session in Fullerton CA by
- combining the Novell and ProTools MIBs. This draft was
- reviewed with the results described below. The goal is for
- the editor to have an updated draft on the mailing list by
- the middle of April, and an Internet Draft by the end of
- April.
- o+ ringOrder Table
- The MIB editor had left out the ring-order table
- because he believed the information could be
- easily obtained from the ring station table. The
- WG felt that the table was so useful that it was
- more than worth the small amount of extra complex-
- ity it added. It will be put back in.
-
- o+ ringStationControl Table
- Text needs to be added to indicated that the
- ringStationControl Table and the ringStation Table
- are associated (ifInterface).
- o+ The MAC Address of the active monitor will be
- added to the ringStationControl Table.
-
- o+ NAUN
- Needs to be added to the ringOrder Table and the
- ringStation Table.
- o+ Data Packet
- Text needs to be added indicating that a Data
- Packet is NOT a MAC Packet.
-
- o+ tokenStats
- remove the words "including those in bad MAC Pack-
- ets"
-
- o+ The AllRoutesBroadcastPckts variable was deleted
- from the basic stats because it already exists in
- the source routing group.
- o+ host Table
- Define a Station Address as "Station MAC Address
- minus Source Routing Bits"
-
- o+ matrix Table
- Make sure to indicate that Station Address (MAC
- Address) does NOT include Source Routing Bits
- o+ MAC vs LLC
- Make sure that MAC vs. LLC vs. Other is well
- defined as far as packet types. The token ring
- standard will be checked for the correct wording.
-
- o+ In/out line errors
- Add burst and in/out line errors (similar to bea-
- cons) back into error list in the ringStation
- Table, since this can improve the ability to
- correctly identify a problem domain.
- There was a lot of discussion about whether the TR MIB
- should be usable by a non-promiscuous probe. After
- much debate it was decided that token ring was signifi-
- cantly different from Ethernet and that all of the use-
- ful fault management and configuration info could be
- acquired by just examining MAC frames (without the
- overhead of promiscuous mode). Accordingly, the WG
- decided to repartition the token ring MIB into (essen-
- tially) four groups:
- 1. Promiscuous stats (frames, octets, size distri-
- bution, etc.)
- 2. MAC layer stuff (ring station table, ring order
- table, augmented with MAC layer counts which were
- previously in the stats group - these would be
- added to the ring station control table).
- 3. Ring configuration information that required
- active gathering methods.
- 4. Source routing stats
-
- For each entry in the History control table both a
- promiscuous history and a MAC layer history (with the
- same parameters) will be generated iff appropriate.
- The Config table will be split into a control table
- (containing the "push buttons" update-stats and
- remove-station and a time of last update), and a data
- table which contains the actual data. All columns must
- be present in the data table, but the row only comes
- into existence (or is updated) when the button is
- actively pushed in the control table.
