That is correct, most enterprise level switches support the Spanning-Tree protocol that checks when a device is connected that it does not cause a loop. A loop would be when someone connects a hub to two switches, a loop like that could take down an entire network. In MOST cases if the switch is being used as an access layer the switch will be configured for portfast to avoid this all together but if the switch is in a datacenter it is probably enabled. This is not an issue that NM has faced alone, Win9x and older MAC OS versions had problems with this. Here are some links (Dry reading!) on STP and portfast on Cisco switches in particular: http://www.cisco.com/warp/public/473/12.html http://en.wikipedia.org/wiki/Spanning_tree_(networks) http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/sw_ntman/cwsimain/cwsi2/cwsiug2/vlan2/stpapp.htm Thanks, Darren _______________________________________________ NetworkManager-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/networkmanager-list
