rx2660 flooding problem on MP LAN
when more then one rx2660 connected to a LAN-segment under control of CheckPoint Firewall, massive UDP flooding can be observed, leading to difficulties reaching other machines connected to the same segment. DHCP on the MP is Disabled. When disconnecting one rx2660 from the segment state is normal again.
MP-Version: F.01.58
Firewall Nodes: CheckPoint SecurePlatform NG withApplication Intelligence (R55) Build 091
Messages captured are zillions like tis here:
13:03:35.107388 IP (tos 0x0, ttl 189, id 0, offset 0, flags [none], proto: UDP (17), length: 65) 10.90.10.57.8116 > 167.66.66.0.8116: [bad udp cksum 6ceb!] UDP, length 37
Any followers??
//best,

Re: rx2660 flooding problem on MP LAN
It is probably a hardware flaw.
First try updating the firmware of the MP. If this does not help call hardware, report the behavior and the MP card can be replaced.

Re: rx2660 flooding problem on MP LAN
It would be good to do that even if 10.90.10.57 happens to be an IP from one of the MPs. Serves as a sanity check in case say more than one MP/system has been configured with the same IP address.

Re: rx2660 flooding problem on MP LAN
I do have exactly the same issue, and am very interested in what the solution will be! I logged a call with HP when we first noticed the issue here (some months ago now), but they were (are still?) unaware of any issues - our rx2660's are certainly at the very latest firmware revs...
Currently, the network group have had to put acl's on the switches so the traffic is "blocked", but it is a pain.
I'm actually very glad to see someone else have the same problem (if you know what I mean) - perhaps you could officially log this with HP also so they know it is not just me!
Cheers,
Graham.

Re: rx2660 flooding problem on MP LAN
Thank to all of you who ansered me. Some answers:
@Steven: I already opened a case at HP. Solution see answer to Graham. Firmware is latest and greatest.
@Sameer: we did that. But we need the synching, so we cannot stop it.
@Rick: This was the first thing that we checked (douple IP's/ double MAC-Addresses). We found no duplicates. We also have 30 rx2620 machines connected to the same network. They behave normal. If all 23 rx2660 machines are connected to an independent Network-Switch (which means the CheckPonit Package does not reach them) they behave also normal. But then I have to access them via a notebook in order to access the MP. See also workaround as proposed by HP in the anser to Graham.
@Graham: This ist really good news to me to hear that someone else also suffers from the same problems as I do.
The workaround from HP is as follows: put a small router between the 10.90.x.y network and the flood-causing machines, which isolates them from receiving the CeckPoint StateSynch package. Of course, the isolated machines must change their MP-IP too (we use 10.91.1.x).
We also received statements from HP that the MP-multicast issue will be solved in the upcoming Firmware-release (scheduled to be availabe November to January)

Re: rx2660 flooding problem on MP LAN
So it looks like the issues revolves around iLO 2 MP in here and maybe HP is aware of this and is working on them.
Specifically in this case and I don't know how far it will make any sense, iLO2 MP ASIC does have an inbuilt firewall and somehow closing the port 8116 at MP level could have avoid this issue?
