6031.0. "mcc problems" by GLDOA::DSMITH () Wed Jun 22 1994 19:17

I am doing consulting at a site with DECmcc (V1.3) and am having a couple
problems.   Any assistance would be appreciated!  Thanks...Doug

1.) what causes this message in the mcc_evc_sink.log file?

>>Error translating MCC event 3, status = 1000, 16-JUN-1994 15:51:05.41
16-JUN-1994 19:18:30.41, Received COLLECTOR message over UDP/IP

2.) We have a recording that gathers all counters for part = * every 15 
minutes.  We have rules that check inbound/outbound util against this
historical data. [i.e.:
    (SNMP RT0001 Interface 4 inbound utilization > 70,   AT every 00:15:00,
     FOR start  = (-00:15:05) duration 00:15:00,    in domain 
     .domain.brk-routers) ]

Occasionally during the day I get interminate rule failures with 
this information: "Statistics requires two counter samples; fewer
returned."

Does this mean I missed receiving a poll?  Is there a work around?

3.) Can I limit the IP poller to only one domain (and not a domain's 
children)?

4.) When I upgrade TCP/IP services for OPENVMS from 2.0 to 2.0e or 2.0e
to 3.1 will this break MCC?  Will I have to relink the TCPIP_AM or any
other components?

6031.1	udp_timeout, udp_retries?	GLDOA::DSMITH	`Thu Jun 23 1994 10:13`	8
	>> Does this mean I missed receiving a poll? Is there a work around? If I am missing polls, is there any way to tune the udp_timeout/retries parameters used by the historian process? Thanks Doug
6031.2	MCC specialized exception code : 3	GLDOA::DSMITH	`Mon Jun 27 1994 14:24`	11
	RE: .0, ITEM 2 I am seeing the following error code when I went back and looked at the last poll failure reason. Any pointers that might help me track down an exception code : 3 error? Time of last failed poll = "27-JUN-1994 08:32:59.40", Last poll failure reason = "MCC specialized exception code : 3", Thanks, Doug
6031.3	MCC specialized exception code : 2	GLDOA::DSMITH	`Mon Jun 27 1994 14:38`	11
	RE: .-1 I am also seeing exception code 2 errors. Any pointers to where these are described? Time of last failed poll = "26-JUN-1994 07:38:44.06", Last poll failure reason = "MCC specialized exception code : 2", Thanks, Doug
6031.4	can I minimize my exception 3s?	GLDOA::DSMITH	`Mon Jun 27 1994 15:38`	12
	From reviewing previous notes (I know I should of done this first) exception code 2 is "no response from entity" and exception code 3 is Internet communications device error !<InetDevError>". Given this insight the code 2's occurred when upgrading ucx. RE: .1 Is there anyway to increase retries or timeout values to minimize the exception code 3s? I poll 64 interfaces and the interfaces two routers away on the slower lines are giving me the most indetermine alarm messages (utilization statistics). Thanks Doug
6031.5	Invalid SNMP PDU	GLDOA::DSMITH	`Thu Jun 30 1994 18:46`	10
	I set up protocol traces of the "no response from entity" errors from supposedly missed polls (re: .-1). The traces show that occasionally a misformed snmp packet gets generated by MCC. They are resent at UDP_TIMEOUT intervals and of course get no response. If anyone is interested I will be happy to post trace information here. In the mean time my customer and I have escalated this problem through proper support channels. Thanks, Doug
6031.6	invalid protocol generated	GLDOA::DSMITH	`Mon Jul 11 1994 16:55`	104
	The MCC station sends an SNMP packet that appears to be invalid in frames 11, 14, and 17. The following frames result from polls generated by the historian process from the following recording: record snmp .ip.RCHRT0001 interface 2 PARTITION = * , - poll PERIOD = 00:15:00, keep age 30, - in domain .domain.brk-routers In the PROTOCOL SAMPLE below frames 1-4 result get the "Identifiers" partition information. Frames 5-8 result get the "Status" partition information. Frames 9-17 should be attempting to get the "Counters" partition, but the get SNMP Protocol Data Unit appears to be an INVALID ENCODING. Frames 18-21 get the "Characteristics" partition information. I have included a protocol breakdown and hex dump of the PDU with the INVALID ENCODING below. The protocol sample should be viewed in 132 column mode as it doesn't quite fit in 80 colums. ------------------------------------------------------------------------ PROTOCOL SAMPLE: Notes: 1. In this example BRKRT0001 is the DEFAULT IP GATEWAY for the MCC subnet. 2. The MCC station's IP address is 167.6.2.10/DECnet address 15.108. 3. BRKRT0003 is the IP GATEWAY directly attached to the destination router. 4. The destination router's (RCHRT0001) IP address is 180.9.254.253.
