My networks all use VLANs for QoS. Unfortunately, Elastix does not have vconfig installed so there is no turnkey support for VLANs. However, it is a quick fix which takes about 5 minutes to remedy. *****Make sure your switches/routers support and are configured for VLAN tagging, or this will NEVER work for you.***** Here's the scoop: //PRODUCT SPECIFICS Summary: Linux 802.1q VLAN configuration utility Version: 1.9 Size: 49371 License: LGPL Packager: Comodo Trustix //INSTALL INSTRUCTIONS First we need to change to a temporary storage location for our RPM... cd /tmp Now we will snag the RPM from the web... wget ftp://ftp.trustix.org/pub/trustix/relea ... r.i586.rpm Finally we need to install the RPM... rpm -ivh vconfig-1.9-2tr.i586.rpm That's all!!! //SIMPLE VLAN SETUP (This is just a sample, as always YMMV) Down interface and reset IP... ifconfig eth0 down ifconfig eth0 0.0.0.0 up Add the 8021q module to the kernel... modprobe 8021q Add your VLAN(s)... vconfig add eth0 10 or vconfig add eth0 <YOUR VLAN HERE> Configure VLAN(s)... ifconfig eth0.10 192.168.1.12 netmask 255.255.255.0 broadcast 192.168.1.255 up or ifconfig eth0.<YOUR VLAN HERE> 192.168.1.12 netmask 255.255.255.0 broadcast 192.168.1.255 up Ping out to test ...done.
