I am working on setting up PacketFence in a test environment and most of it is running smoothly and working very well. I am currently having an issue where the user machine that I am using to test with is Ubuntu 10.04 and there seems to be some setting in Ubuntu (maybe Linux in general I haven't tried any other distros yet) where it delays for about 5 seconds before the network interface registers as down after it has been unplugged or the interface is shutdown. My guess is it does that so if there is a slight hiccup in the link it doesn't lose its connection.
The problem is it causes the connection to not be reset when PacketFence flips the vlan and admin status of the port. Looking at the logs in packetfence and the switch, it is actually shutting down the port and bringing it back up. Ubuntu though, is not showing the interface as down so I have to manually reset the interface on Ubuntu to get an IP address on the newly set vlan. I tried a Windows 7 machine and it worked fine because it immediately registers the interface as being down. Has anyone else run into this issue? Would there be a way to program in a delay between the admin status down and up SNMP writes to the switch so it would leave the port down for some set amount of seconds? Thanks for any help.
