User Guidelines
Root guard can be enabled when the device operates in STP, RSTP and MSTP.
When root guard is enabled, the port changes to the alternate state if spanning-
tree calculations selects the port as the root port.
Example
The following example prevents Ethernet port e1 from being the root port of the
device.
Console(config) # interface ethernet e1
Console(config-mst) # spanning-tree guard root
