Telnet/SSH is suboptimal because of speed but mainly because we need to use an interface meant for humans (error-handling problems and lots of back and forth). We never recommend using linkup/linkdown traps on more than a handful of switches. One booting PC tends to generate 2-3 linkup events and 2-3 linkdown events. On each of the linkups PacketFence needs to reserve a thread polling the switch in SNMP to see the MAC address appear in the MAC detection VLAN. There are mechanism to remove duplicated traps but it is still way more work than getting a port-security trap with the MAC already in there. Bottomline is: If the switch is rebooted, linkup/linkdown will cause greater load than port-security even if using Telnet for authorization. Also, on the Telnet vs SSH, telnet is lighter than SSH on the switch. > I have a few of these and also some 3Com 5500G and 4800G - the software on > those is very similar to the 4200G so I am hoping to get it to work with all > of them. > > Sadly, HP bought 3Com out last year and I suspect these will go end-of-life > shortly, if they haven't already - so I doubt HP will be of much help. > For access products I think you are right, in the long term they'll go end-of-life but I've heard that the 3Com stuff is pretty good for the core and that they might keep the core products around. I'll email you in private with some pricing for development/testing on the modules to improve them. Usually we aim that the vendor pays for that but I'll let you know anyway since you don't seem to have a lever on them unfortunately.
