Cat 5500 and spanning tree problem and port fast

Hi Guyes,

I have a question about the following

A server is connected to a port. Whenever the backup are taken or the server restarts there is loss of connectivity on a perticular vlan on that switch. Even changing the port on the switch hasn't helped. Even configurinh port fast on that port didn't help. Only when port fast was enabled for all devices on that vlan the problem went away. Why a Server should initiate such a outage?

Re: Cat 5500 and spanning tree problem and port fast

What type of switch do you have?

You may want to see if the SET PORT HOST command is available on your switch. This is a batch command that sets portfast, and disables the automatic Etherchannel and trunk detection as well. This takes the startup time of a port down to less than a second. You want to make sure you use that ONLY on ports that have end stations (workstations, servers, etc) connected to them.
