Default Re: ClusterXL and VLANS

A couple things to add, as well as some questions...

I imagine this is common. As our network has grown, we initially just used unused interfaces, as we realized we were running out of them, we started adding VLAN's. At this point, we wish we'd known more about VLAN's earlier in our growth, as we've really wasted a lot of physical interface on networks segments with low traffic.

Setting up the Vlans, must i configure a IP adreess to the physical interface associated with the VLANs ? If yes, how must it be configured in the topology ? using Monitored Private ?
Well, we are doing this, but our pivot is spamming /var/log/messages with warnings. It works, but we're getting more out-of-state messages than we think we should be, and the warnings in /var/log/messages are disconcerting, at least.

After 6 weeks of having a ticket about the warnings, they finally came back with "remove the IP's from the physical interface, and only use IP's on the subinterfaces." That's a pretty big project with some pretty big implications, so we're working on it, but I agree with chillyjim, the proper way is to have no IP assigned on the physical interface, and to only use subinterfaces.

They said to make the physical interface "monitored private". I'm not sure how this will work when there's no IP assigned, but I'm going to find out in just over a week.

In SmartViewMonitor i just see the physical interface and the IP address of the VLan with the lowest Tag ID....
If this is how it works when no IP is assigned to the physical interface, I'll be quite happy.
