MSTP

Dear Friends
I wish u r all fine ..... Ihave question about MSTP and wish u could help me solve it ... why switches wait until you are finished making changes to MST to commit them , rather than changing MST as you enter commands ??? I mean that when u enter mst configuration mode and begin configuring revision number , region name , vlans to instance, the commands are not committed until you exit mst configuration mode......why ????

Thanks in advance

Perhaps to prevent every comand you enter from causing spanning-tree to rebuild your L2 forwarding topology and only do it once when you exit MST configuration mode, less network instability that way. I'm not sure if this is why but that would be my guess.

Not only what dtlokee said, but in addition, until your commands are completed you can have a faulty config that hurts your network connectivity.

It's a problem I've noticed with ACL's, actually.
