To configure loop guard use the following command:
switch (config interface etherent <inf>)# spanning-tree guard root
5.5.6 MSTP
Spanning Tree Protocol (STP) is a mandatory protocol to run on L2 Ethernet networks to elimi-
nate network loops and the resulting broadcast storm caused by these
loops. Multiple STP
(MSTP) enables the virtualization of the L2 domain into several VLANs, each governed by a
separate instance of a spanning tree which results in a network with higher utilization of physical
links while still keeping the loop free topology on a logical level.
Up to 64 MSTP instances can be defined in the switch. Up to 64
VLANs can be mapped to a sin-
gle MSTP instance. MSTP instance 0 (the default instance) may have all
possible VLANs (1-
4094) mapped to it.
For MSTP network design over Mellanox L2 VMS, please refer
to Mellanox Virtual Modular
Switch Reference Guide.
