Bob, on A44RTR is see SG1 flapping as well. After breakfast I'll see whether there is a pattern. Initially I thought it was the linux laptop going to sleep after a whule. That may not be the case.

Let me know if you need an extra pair of hands with VMware ESXi; I run a big host machine here and several more for clients. And...What model of VAXstation?

This end is a FVS318... -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Bob Armstrong Sent: Saturday, June 09, 2012 18:45 To: hecnet at Update.UU.SE Subject: RE: [HECnet] netowrk flapping.... and Bob A has a home gw (forgot what it was) that he claims do the right thing, (not decnet routing..) Well, I have a Netgear FVS338. It's a "SOHO" box - somewhere between a turnkey home router and a fancy Cisco box. I never thought of it as all that great, but it does allow me to set up static routes. In particular I can map specific external ports/Internet IPs to internal ports/IPs independent of the NAT. Bob

Any chance this device can be replaced with something IP compatible? (What's the uplink interface?) I don't know of a device that I could easily replace it with that is still supported, has VLAN support with multiple virtual interfaces, and without being too prohibitive for a home router. The uplink port is a gigabit port connected to my FiOS ONT (connected at 100 Mbps). --Marc

netowrk flapping....

by roll＠Stupi.SE

With my connection, I noticed that the circuit would disconnect and reconnect periodically. It corresponded to the timeout in my firewall causing the UDP association to be lost. When I increased the timeout in my firewall for these port 700 UDP "connections", that made my circuit much more stable. Like Peter said, Peter and I had a big debate about this at lunch today. UDP is, by definition (or so I thought), both stateless and connectionless. I can't understand what state or connection is being timed out in this case.... Yes, a UDP session is connectionless, however when a firewall is doing NAT and/or PAT (remember I mentioned that my firewall is randomizing the source port number, so the LAN port numbers are different from the ones sent over the internet), it needs to maintain a session table to keep track of which IP addresses and port numbers map to which systems and port numbers locally. Those connections time out after a while, and then subsequent UDP packets wouldn't be recognized. Any chance this device can be replaced with something IP compatible? (What's the uplink interface?) --P

Network flapping, what's it all mean????

by bob＠jfcl.com

Ok, I looked thru 36 hours of OPERATOR.LOG on LEGATO for listener receive timeout adjacency down/adjacency up ( flapping as Peter calls it). Here s what I found The Multinet connection to SG1 flaps all the time, almost like clockwork, with a period of about 20 minutes. The Multinet connection to GORVAX flapped once in that same 36 hour period. The Multinet connection to STUPI never flapped, although it did suffer from one corrupted packet error. The Multinet connections to CIERE and FRUGAL never, ever, flapped nor suffered any corrupted packets. So, what s it mean?? Bob
