Hi, I am new in vlan 802.1q and I really need your help. 1) I?d like to know how to active vlan 802.1q on SUN Solaris 8 and 9 ? And where to find the patch ? 2) I use also Red Hat 7.2 kernel 2.4.26, the module 8021q is already installed, and ? modprobe 8021q ? works well. But should I compile a new vconfig for my kernel or can I use the vconfig in the file ? vlan.1.8.tar.gz ? found on the web or this file http://scry.wanfear.com/~greear/vconfig? What is the best choice ? And where should I copy the file vconfig ? In /sbin/ , /usr/local/sbin/ or /usr/local/bin/ ? 3) I have create two vlans : it works well vconfig add eth0 2 vconfig add eth0 3 but when I reboot the vlans disappear. So how can I do to make it permanent after the reboot ? I have heard that we can modify or patch some files for vlan 8021q like : /etc/sysconfig/network-script/ifup /etc/sysconfig/network-script/ifdown /etc/init.d/network Is there some patch for that ? On a Debian server, I have tried to do this an dit work well : ? auto eth0.2 iface eth0.2 inet static address 192.168.1.1 netmask 255.255.255.0 pre-up /usr/local/sbin/vconfig add eth0 2 ? What is the best practice ? 4) I want to change the IP address, and want to use trunk 802.1q to help me doing that by creating two vlans per server and per NIC, do you know if the applications like apache, mysql, dns server, postfix server, etc will accept and work with two IP addresses per server in their config files ? If anyone has already changed Ip address by using 802.1q, I will be happy to accept your advices. 5) I have a broadcom card, should I use the driver tg3 or bcm5700 (version 7.3.5) for trunk 8021q ? Does it need to patch ? Thanks you very much for your help, Robert ___________________________________________________________________________________________________ Le nouveau Yahoo!
