STP, RSTP, and MSTP configuration guidelines and restrictions

STP, RSTP, and MSTP configuration guidelines and restrictions
Follow these configuration guidelines and restrictions when configuring STP, RSTP, and MSTP.
• You have to disable one form of xSTP before enabling another.
• LAGs are treated as normal links and by default are enabled for STP.
• You can have 16 MSTP instances and one MSTP region.
• Create VLANs before mapping them to MSTP instances.
• The switch supports up to 65 MSTP instances.
• For load balancing across redundant paths in the network to work, all VLAN-to-instance
mapping assignments must match; otherwise, all traffic flows on a single link.
• When you enable MSTP by using the global protocol spanning-tree mstp command, RSTP is
automatically enabled.
• For two or more switches to be in the same MSTP region, they must have the same
VLAN-to-instance map, the same configuration revision number, and the same name.
Default STP, RSTP, and MSTP configuration
Table 9 lists the default STP, RSTP, and MSTP configuration.
Table 10 lists the switch defaults that apply only to MSTP configurations.
