Re: Multiple "link up" messages, SP 8.25A, Windows 2008
I finally ended up going to Insight Manager and disabling the LinkUp trap. (Options -> Events->SNMP trap settings.) the trap is in mib rfc1215. I still get enough traps on reboots to tell what is going on (coldstart, etc) but it keeps my mailbox from being flooded with LinkUp traps. Not the optimum solution but that's the best I could come up with.

Re: Multiple "link up" messages, SP 8.25A, Windows 2008
What I'm not sure yet is if this is specific to ESX VM Guests, or whether this will be the case with physical servers as well. All of our 2K8's are ESX VM's right now, but I'm in the process of building out a physical server to see if there's any difference in the trap reports. The VM guests don't have the agent installed, so that may be a factor as well.
Has anyone seen these errors on physical servers? Please let me know what your experiences have been with this.
Google hasn't been too helpful. If I can get some info on your experiences/scenarios, I'll go to either MS PSS or VMWare support next and post results.
Thanks,
John

A linkUp trap signifies that the sending protocol entity recognizes that one of the communication links represented in the agent``s configuration has come up.

Re: Multiple "link up" messages, SP 8.25A, Windows 2008
To illustrate what I'm talking about with my issue, take a look at a 2K3 server and a 2K8 server. Go to the 'Tools and Links" tab for that server and run the 'Data Collection Report'. In my case, comparing 2 VMs in this report I get significantly different results, notably in the network/NIC section. Where there is only 1 entry in the 2K3 report, there are about 15 in the 2K8 one - most reporting the same MAC addy.
I think this has something to do with the new 2008 network stack/config. SNMP is reporting 'linkup' for each protocol, instead of just for the NIC/IP. What I'd like to be able to do is turn off the firehose of info.

Re: Multiple "link up" messages, SP 8.25A, Windows 2008
After having checked things out with a Escalation Tech, I was told the following by PSS:
"As we discussed, it appears that Windows Server 2008 is sending traps on the additional interfaces (ipv6, wan-mini, qos, etc) where 2003 did not. I will dig into the captures you provided. Unfortunately, if this is the case, there is currently no configuration granularity within the available SNMP interfaces that would allow you specify which interfaces to alert on. The solution may be to turn of Physical alerting, as being suggested in the HP threads, and using EVNTWin to alert on selected Event Log entries, such a start up events or service start event."
The latter suggestion is the use of a little-known utility to create custom alerts. Not sure how efficient this will be in a large enterprise.
I sent him network captures that the HPSim box received during a 2008 server reboot, so it's not TOTALLY written off, but it doesn't look like this is configurable from the 2008 OS perspective.
HP is coming in a week or so to upgrade our HPSim to the most recent version. Is anyone running the most recent, and is there any way to trim the alerts at the HPSim point in this version?
If PSS comes back with anything else, I will post results here.
