Stp Max-Hops - H3C S7500E Series Command Reference Manual

Parameters
None
Description
Use the stp loop-protection command to enable the loop guard function on the port(s).
Use the undo stp loop-protection command to restore the system default.
By default, the loop guard function is disabled.
Configured in Layer 2 Ethernet interface view, the setting takes effect on the current interface only.
Configured in port group view, the setting takes effect on all ports in the port group. Configured in Layer
2 aggregate interface view, the setting takes effect only on the aggregate interface. Configured on a
member port in an aggregation group, the setting can take effect only after the port leaves the
aggregation group.
Among loop guard, root guard and edge port settings, only one function (whichever is configured the
earliest) can take effect on a port at the same time.
Related commands: stp edged-port and stp root-protection.
