Several of you have been kind enough to offer advice about the repeated "SVCDOWN ... Interface(x) .... missed 1" I get from several of my Cisco routers. I have been asked for more specific details about the affected machines: the models include 2501, 2610 and 3640, running a range IOSs from 10.3 to 12.2. The interfaces affected include Ethernet, Serial (leased line) and Serial (frame-relay) . Thus there seems to be no common link between the devices. Also, all interfaces were successfully "auto discovered" by WUG during initial configuration.
In a bid to better understand the Service Interface mechanism I have begun to look at the debug log (which provides a wealth of information). It seems to me (and this is borne out in the Help Manual) that when a device is polled, the specified interfaces' MIBs are checked to determine whether the given interface is up or down. For some reason, at regular intervals, when polled these machines appear to be asserting that certain interfaces are down. However, a check of the devices' Syslog logs shows quite clearly there was no such outage. Furthermore, I've started ICMP polling individual interfaces, and they show no pings being missed. This is all most annoying , because it means my logs fill up with spurious SVCDOWN messages and I am rather losing faith in what is or isn't an alarm. I would rather not have to disable interface monitoring but at the moment I don't see any other option. Has anyone else experienced similar problems with Service Monitoring interfaces? -- NOTICE: The information contained in this electronic mail transmission is intended by Convergys Corporation for the use of the named individual or entity to which it is directed and may contain information that is privileged or otherwise confidential.
