plz see the attachment......in the image if the rogue switch is trying to become the root then in this scenario if we want to protect the root bridge on which ports root guard can be applied ??
2. Also if root guard is applied then the ports go into root inconsistent state ....then as an administrator how can we know that the root bridge has changed, i mean to ask what changes can be observed in the network BEFORE using the "show spanning-tree inconsistent ports command"
