The first chain sequence is really a little bit strange, but it was just to show that such combinations also work. You are right, such a sequence would cause bottlenecks if you transfer heavy traffic through this chain, so servers at the end of the chain are no clever idea. But for a client...

Hello jjcelma For this case you need a router between these subnets. A 3COM SuperStack III 4400 (anyone of this series) can't do this job for you because this device has no routing functionality.

Hello Diffy1 To question 1 There wouldn't be any problems and limitations to chain switches together. At one location I have 7 switches (3COM SuperStack II 1100) chained together in series and there aren't any problems so far. (sw1 to sw2; sw2 to sw3; sw3 to sw4; sw4 to sw5; ...) At another...

Hello Dwayne Oh, now I know why your switch doesn't work like you want. The main problem is that you have different firmware versions in your stack. That always causes a lot of problems. Apart from the very old firmware on your switch. How to update your switch stack: First you have to...

Hello Dwayne Which firmware version do you use on your Superstack switches? When this problem occured, were you able to log into the switch via telnet or does the managemet completely hang on? And did the switch process it's main taks (switching, VLAN, resilent links, trunks, SNMP)? I had the...

Hello Ramzi Which WIC do you use in your Cisco 2611XM router for the leased line? And which Enterprise OS is running on your NETBuilder 111? Do you use OSPF or RIP on your line? What's the interface status on your Cisco router (show interface serial ?/?) We use a lot of Cisco routers (Cisco...

Have you already tried one of these files? http://support.3com.com/software/netbuilder_ii_files_netbuilder_10.1.htm

I don't use the SSIII 4900 for routing because I also have to route DEC and have to provide QOS on some VLAN's. And so all routing actvities were executed trough 3COM Netbuilder's and CISCO routers. On these devices you can also specify a second interface on a VLAN. I use the SSIII 4900...

Hello You can always connect to the switch trough the console port. Maybe you have used a wrong serial cable. To connect to the switch you must use a crossed over cable. If you don't have such a cable and you don't know where to get one, the following link will show you the pinouts...

It would be easy to create a new VLAN if the waggon directly connects to the SSIII 4900. But in my case the waggon is far away from the SSIII 4900 and every packet hops trough several switches. Example: SSIII 4900 Switch 1 Switch 2 Switch 3 Switch 4 Switch 5 Switch 6 Waggon (Workstation) If I'd...

The purpose of the secondary interface: We have technical teams which are situated in waggons. (Track system building, overhead contact line building, signal technicans) These teams have a lot workstations, servers and measuring instruments with fixed IP-Adresses on board.(For example...

The highest level in 3COM Netbuilder enterprise OS is "root" The default root password is a null string, which is generated by pressing the Return key. Hope this helps Sheffield

I think there is no chance for a workaround. Why does your probe need to talk to the console? 3COM says: "When the roving analysis port is set up, it is disabled from receiving or transmitting any other data. It only transmits data to the network analyzer that it receives from the monitor port...

Have you already tried to build the aggregated link trough the web-menue? I haven't configured a SSIII 4250 so far but I guess it will work the same way like on a SSIII 4400. There I have created an aggregated link like the following example: Select menu option (bridge/linkAggregation/modify)...

Have you already cleaned the 100 Base-FX module? The 3300 switches are real dust catcher. Sometimes the dust on the module causes a lot of errors. For example last week I hade the "Christmas Tree syndrom" on a switch but after cleanig the module everythings gonna be okay. Try to upgrade to the...
