Close: if spanning trees are enabled globally, are enabled on the affected port, and the switch port isn't set for "portfast" (see below), then the device will fail DHCP/BOOTP if it tries to get it's lease before the switch port is in the FORWARDING state. With standard 802.1D STP it takes 30 seconds for the port to move from the BLOCKING state to the FORWARDING state, or 10 seconds with the newer 802.1w RSTP. Unfortunately blindly turning off STP in a working environment can be... devastating to the uptime of your network infrastructure ;) Any and all modern bridges (switches are a type of bridge) that support STP also support "portfast" (the Cisco term for it, HP calls it an edge port, many brands use Cisco's terminology) where the switchport will *immediately* begin forwarding traffic while still listening for (and broadcasting) STP bridge PDUs. -- Phil Brutsche [EMAIL PROTECTED] _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
