Re: enable RSTP on some ports from Catalyst WS-C3550-12T
I am afraid that you cannot enable RSTP for just a few ports (vlan). This is done for the whole switch using the global command:
spanning-tree mode rapid-pvst
As you probably know, RSTP is backwards compatible with 802.1d. Therefore you can activate RSTP on your switch and still participate in the old 802.1d network.
A word of caution to finish: Be sure to use a recent software release. There are some issues with RSTP on versions 12.1(22) and below. In fact I am not even certain if these issues have been fixed yet. You might not be affected by them but be warned. When your network starts to behave erratically after the change it might be related to this topic.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
