Hi all,

Recently at work we updated our switch stack firmware ( with the new cisco version 3.0.0.17 ).

Since then all our slackware laptop stopped getting IP from our win 2008 dhcp Server ... and then it ended up to be the spanning tree protocol .... is this an expected behaviour ? is there a way I can work around it ? at the moment I disabled the spanning tree ( isn't a feature I can't live without really though I d like to use it )

Thanks

Apparently it is expected behavior, but a workaround set spantree portfast for catalyst switches is available.

Using PortFast and Other Commands to Fix Workstation Startup Connectivity Delays

"If you connect a workstation or a server with a single NIC card or an IP phone to a switch port, the connection cannot create a physical loop. These connections are considered leaf nodes. There is no reason to make the workstation wait 30 seconds while the switch checks for loops if the workstation cannot cause a loop. Cisco added the PortFast or fast-start feature. With this feature, the STP for this port assumes that the port is not part of a loop and immediately moves to the forwarding state and does not go through the blocking, listening, or learning states. This command does not turn STP off. This command makes STP skip a few initial steps (unnecessary steps, in this circumstance) on the selected port."

Just found a document how to adjust the SGE2000:
