Thank you Peter for your writing. I have another question. 8021q module does not exist on my Montavista CGE 3.1. If I want to install 8021q module, can you point me to links to get this module. I have 2.4.20 kernel.

How do I load the 8021q module on Montavista CGE 3.1? I don't know for sure what tools are included in the MontaVista product, but you could always try the command that is used on less specialized distributions: modprobe 8021q > 2. What is PROCFS and how do I install PROCFS? procfs is a virtual filesystem mounted in the /proc directory on Linux systems. It contains gobs of information published by almost all parts of the Linux kernel. Some kernel drivers also use procfs to communicate with userspace in both directions. > 3. Where can I get VLAN package and how to install VLAN package? Footnote on http://www.mvista.com/products/cge/features.html: "VLAN support requires hardware-specific device driver/ethernet device support. Contact MontaVista Software for specific driver/device combinations that have been pre-validated." So I guess the answer to this is to talk to MontaVista. > 4. What do I need to do in order to reproduce the issue above? Reproduce? Well, you should just have to re-run vconfig. It is supposed to present the same error message consistently when all it's prerequisities aren't available. Resolve? Try the modprobe command as per above, if it completes without error check that the directory /proc/net/vlan exists and then re-run vconfig, it should work now. Hope this helps. //Peter _______________________________________________ Vlan mailing list Vlan@xxxxxxxxxxxxxxx http://www.lanforge.com/mailman/listinfo/vlan
