2622.0. "pb DECmcc/ULTRIX T1.2.4/ETHERNET_AM/FDDI/ETHERNET" by ZTOIS1::VISTA (Renato VISTA, SIS Strasbourg, France) Wed Mar 25 1992 05:47
Hello,
After reading 2612.0 from Fran�ois EBLE, I'm working on the same DECmcc/ULTRIX
T1.2.4 platform (DECstation 5000-25, with Ethernet controller and FDDI
DECcontroller 700c) and I've investigated more precisely about ETHERNET_AM
behavior :
# manage
DECmcc (T1.2.4)
MCC> show mcc 0 ethernet_am all attributes
MCC 0 ETHERNET_AM
AT 1992-03-25-11:35:01.582Iinf All Attributes
Available Ports = { "ln0
,
"fza0
" }
Component Version = T1.2.4
Component Identification = "DECmcc Ethernet AM"
!-----------------------------------------------------------------------------
! First, registration at station level WITH FUNCTIONS SUPPORTED clause given
! AND without VIA PORT clause given...
MCC> register station .station_node.stras4 Address = 08-00-2B-23-83-63,
alternate addres AA-00-04-00-D3-BD,Functions Supported = DEC_ENETV2
STATION LOCAL_NS:.station_node.stras4
AT 1992-03-25-11:05:18.937Iinf
Registration successful.
MCC> show station .station_node.stras4 all char, all id
STATION LOCAL_NS:.station_node.stras4
AT 1992-03-25-11:05:54.016Iinf Characteristics
Examination of attributes shows:
Functions Supported = DEC_ENETV2
Alternate Address = aa-00-04-00-d3-bd
Maintenance Version = V3.0.0
Implementation = DESVA Microvax-2000 3100 3300 CSMA/CD
controller
STATION LOCAL_NS:.station_node.stras4
AT 1992-03-25-11:05:55.008Iinf Identifiers
Examination of attributes shows:
Name = LOCAL_NS:.station_node.stras4
Address = 08-00-2b-23-83-63
MCC> deregister station .station_node.stras4
STATION LOCAL_NS:.station_node.stras4
AT 1992-03-25-11:06:27.004Iinf
Deregistration successful.
!-----------------------------------------------------------------------------
! Next test, registration at station level WITHOUT FUNCTIONS SUPPORTED
! clause AND without VIA PORT clause...
MCC> register station .station_node.stras4 Address = 08-00-2B-23-83-63,
alternate addres AA-00-04-00-D3-BD
STATION LOCAL_NS:.station_node.stras4
AT 1992-03-25-11:06:32.023Iinf
The requested operation cannot be completed
MCC Routine Error = %MCC-E-MMABORT, target management
module thread has aborted
!-----------------------------------------------------------------------------
! Next test, registration at station level WITH FUNCTIONS SUPPORTED
! clause specified AGAIN...
MCC> register station .station_node.stras4 Address = 08-00-2B-23-83-63,
alternate addres AA-00-04-00-D3-BD,Functions Supported = DEC_ENETV2
! NO message, command aborted by CONTROL_C ; NO partial registration done...
! In fact, the mcc_enet_am process seems to be corrupted...
MCC> dir station .station_node.stras4
STATION LOCAL_NS:.station_node.stras4
AT 1992-03-25-11:12:18.133Iinf
The entity STATION LOCAL_NS:.station_node.stras4 is not registered
Not Registered Entity = STATION LOCAL_NS:.station_node.stras4
! SO, KILLing the mcc_enet_am process...
MCC> spa ps -ax | grep mcc
36 ? IW 0:00 /usr/etc/mcc_dna4_evl_monitor 1
8415 ? S 0:16 mcc_tcpip_am 15 N

22055 ? S 3:30 /usr/mcc/mmexe/mcc_tcpip_sink
9906 p0 S 0:00 -h -c ps -ax | grep mcc (csh)
9908 p0 S 0:00 grep mcc
MCC> spa kill -9 9757
MCC> spa ps -ax | grep mcc
36 ? IW 0:00 /usr/etc/mcc_dna4_evl_monitor 1
8415 ? S 0:16 mcc_tcpip_am 15 N

8968 ? S 0:12 mcc_domain_fm 7 N
22055 ? S 3:31 /usr/mcc/mmexe/mcc_tcpip_sink
9914 p0 S 0:00 -h -c ps -ax | grep mcc (csh)
9916 p0 S 0:00 grep mcc
!--------------------------------------------------------------------------
! Next step, doing the first command WITH FUNCTIONS SUPPORTED clause ;
! As the process has been killed, the first command has fails,
! BUT the second one has run correctly because the mcc_enet_am process
! has been created... (always WITHOUT VIA PORT clause...)
MCC> register station .station_node.stras4 Address = 08-00-2B-23-83-63,
alternate addres AA-00-04-00-D3-BD,Functions Supported = DEC_ENETV2
STATION LOCAL_NS:.station_node.stras4
AT 1992-03-25-11:13:50.930Iinf
The requested operation cannot be completed
MCC Routine Error = %MCC-E-TRANSMITERROR, error trying to
transmit a packet
MCC> register station .station_node.stras4 Address = 08-00-2B-23-83-63,
alternate addres AA-00-04-00-D3-BD,Functions Supported = DEC_ENETV2
STATION LOCAL_NS:.station_node.stras4
AT 1992-03-25-11:13:53.906Iinf
Registration successful.
MCC> deregister station .station_node.stras4
STATION LOCAL_NS:.station_node.stras4
AT 1992-03-25-11:38:21.605Iinf
Deregistration successful.
!--------------------------------------------------------------------------
! FINAL step, the registration command WITHOUT FUNCTIONS SUPPORTED clause
! BUT WITH VIA PORT clause...
MCC> register station .station_node.stras4 Address = 08-00-2B-23-83-63,
alternate addres AA-00-04-00-D3-BD, via port = ln0
STATION LOCAL_NS:.station_node.stras4
AT 1992-03-25-11:36:05.285Iinf
Registration successful.
MCC>exit
NOTE that
1) the registration command runs also correctly with a VIA PORT =
fza0 (ie via FDDI controller) clause !
2) if a the Ultrix Command is done previoulsy
#ifconfig fza0 down
and a registration command is done with VIA PORT = fza0,
a partial registration is done with the following messages :
Partial registration success. Please retry later to complete the registration.
Reason for Partial Registration = Cannot communicate with target
SO, the mcc_enet_am process seems to be corrupted by a registration command
WITHOUT FUNCTIONS SUPPORTED clause (without also VIA PORT clause).
Note that this way of registration runs correcty on a DECmcc/VMS V1.1 platform
(ie on a DECmcc/VMS V1.1 mVAX 3800 platform with ETHERNET controller only,
so with a registration command WITHOUT FUNCTIONS SUPPORTED CLAUSE and
WITHOUT VIA PORT clause).
Thank you for your help !
