Hi,
A customer is experimenting with Requested TRT (amongst others) in
an FDDI-ring for some research purposes.He's using SMT and it's working
fine for all stations except DECconcentrator 500 (DEFCN-AB).
The DEFCN_AB has got a management module in place (DEFCN-MB),and he
should (?) therby be able to change t_req by SMT.
This fails,and as the DEFCN-AB has no OBM-port he has found himself stuck.
Questions:
What does it take to make SMT work as expected ?
or
What does it take to get an OBM-port on the DEFCN-AB ?
Any help deeeeply appreciated !!!
SMT-response from the DEFCN-AB follows:
( polling for t_req av DecConcentrator 500 from 3Com
Linkbuilder 3GH :)

Jon,
The controller/backplane card contains a 20 pin connector
provided for connecting an external UART card (22-00912-01), or
you can use the internal UART (54-19449-01). Remove the top cover
and connect either UART to the backplane connector using the cable
(70-16738-01). You may want to tape over the back of the UART to
insure it doesn't short out against the box, to limit access to
the inside of the box drape the cable over the back of the box and
replace the cover.
Terminal speed will be 2400 baud, after power-up the OBM menu
should come up. If the power indicator led on the box is flashing
reverse the connection of the cable to the UART.
We'll look into the SMT difficulty.

When you say you are "using SMT" are you trying to do PMF SETs and GETs? If so, you have to have SMT 7.2 running in the DEFCN. PMF frames were optional before SMT 7.2. I'm not sure what version of firmware has 7.2 (DEFCN people can answer that.) If you are doing PMF SETs the Authorization (parameter 00 21) must be used and have the value of the SNMP community string. One comment : WHY are they using PMFs? SNMP is THE right way to manage your network. PMF SETs are still optional. Luc | |||||
| 1213.3 | SMT 7.2 is in defcn 3.2 | NPSS::TAYLOR | Mon Jan 24 1994 08:09 | 5 | |
SMT 7.2 is in DEFCN version 3.2 and later.
