With a managed switch, a savvy network manager can sidestepG those problems by forcing the switch to the right settings.  A confused - network manager will often make things worse.   H Autonegotiation problems mostly plague 100 Mbit/sec ethernet links.  The= duplex setting ends up wrong more often than the speed.  On a A lightly-loaded network, the symptoms may be hard to notice.  On a E heavily-loaded network, the protocols that are least aggressive about J re-transmitting lost packets quickly (usually DECnet) will suffer greatly,) but problems can be seen in any protocol.   H My (limited) understanding is that the 100 Mbit/sec ethernet specs leaveF some of the autonegotiation process a bit vague, and different devicesI behave differently (while still complying with the specs).  Sometimes the F result is a mismatch.  1 Gbit/sec devices seem to have gotten past the* problem, since the spec has been improved.  I Recent VMS versions have MUCH better robustness around autonegotiation in J the LAN device drivers.  And the LANCP utility makes it easier to see whatC is going on from the VMS side, and control network settings to some G extent.  You no longer have to reboot to change the duplex setting, for  example.  L >Also, my netgear box with a built-in unmanaged switch has shown it doesn't ' >handle cluster traffic 100% properly.    G Details of the deficiencies might be useful here.

They filter E based on LAN address.  They pay no attention at all to the high-level " protocol buried inside the packet.  J VMS and windows send and receive packets.  Typical PCs probably do it muchE faster than your VMS hardware, since (I believe) typical PCs are much I newer than your dated VMS systems.  So stuff "designed for the PC market" G may be designed to handle network loads that you can never acheive with # your VMS systems.  Sounds ok to me.   M I'm curious how you perceive a PC's use of ethernet to differ from VMS's use.   M >In practice, is the loss of ethermon capabilities with use of a dumb switch   >an issue ?   E Dunno.  I've never used it.  Do you find yourself diagnosing a lot of E ethernet problems?  In a small installation, you can often get enough J monitoring information from the hosts, so you may not need to monitor from the switch side.    I >Would I be better off buying an older used Cisco switch with management  J >capbilities (also gives me experience on Cisco's IOS), or is buying just * >any cheap switch brand new still better ? > E >(I don't need gigabit speeds, since as far as I know, HP hasn't yet  M >produced a q-bus gigabit ethernet adaptor for my VAXes...) ajnd even on the  = >alphas, it is 100mbps with the built-in ethernet adaptors.).  > C >Also, in terms of speeds, since a switch is store-and-forward and  J >introduces a latency in packet delivery, is that significant in terms of 8 >clustering and most notably MSCP access over ethernet ?  G Almost any switch can handle traffic on a few ports at full wire speed, I with small enough latency that it doesn't matter.  Good switches can keep E all the ports busy, with little or no latency degradation under heavy  load.   I Read the specs for the switch you are considering.  If you think it is an E issue in your situation, spend more money to get a switch with better  latency.  J Unless you make an effort to actually measure latency and response time onG your VMS system, you likely won't notice a difference due to a switch.  J One of the first places latency problems can be seen in often lock managerE traffic in a VMS cluster.  What is your performance now?  Do you have D problems under heavy locking loads?  (Do you ever have heavy lockingI loads?)
