Hello everyone, Thanks for thoughtful and thorough advice. No luck so far, though. I have two VLAN's now - 0003 and 0004, named "vlan3" and "vlan4" respectively - and still for some reason the CentOS fails to recognize them as one would expect. So I am puzzled as to what is still missing from the

Boris, I'd suggest reviewing the guide from Redhat on configuring your server (https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s2-networkscripts-interfaces_802.1q-vlan-tagging.html) In essence, eth0 is a shell. eth0.x is where all the traffic h

[CentOS] Centos box and Cisco 3750 VLAN's

2014-05-30 Thread Boris Epstein
Hello all, I have a CentOS box that has a NIC (eth0) on which I defined 4 VLAN's (counting the NIC itself): eth0, eth0.1, eth0.2 and eht0.3. Initially the Cisco switch was not partitioned into VLAN's which means that the only VLAN running on it was the default one (VLAN 1). I have then played wit
