Release L.10.02 includes the following enhancements:

MSTP Default Path Cost Controls

Summary: 802.1D and 802.1t specify different default path-cost values (based on interface speed).
These are used if the user hasn't configured a "custom" path-cost for the interface. The default of this
toggle is to use 802.1t values. The reason one might set this control to 802.1D would be for better
interoperability with legacy 802.1D STP (Spanning Tree Protocol) bridges.
To support legacy STP bridges, the following commands (options) have been added to CLI:
spanning-tree legacy-path-cost - Use 802.1D values for default path-cost
no spanning-tree legacy-path-cost - Use 802.1t values for default path-cost
The "legacy-path-cost" CLI command does not affect or replace functionality of the "spanning-
tree force-version" command. The "spanning-tree force-version" controls whether MSTP will
send and process 802.1w RSTP, or 802.1D STP BPDUs. Regardless of what the "legacy-path-cost"
parameter is set to, MSTP will interoperate with legacy STP bridges (send/receive Config and
TCN BPDUs).
spanning-tree legacy-mode - A "macro" that is the equivalent of executing the "spanning-tree legacy-
path-cost" and "spanning-tree force-version stp-compatible" commands.
no spanning-tree legacy-mode - A "macro" that is the equivalent of executing the "no spanning-tree
legacy-path-cost" and "spanning-tree force-version mstp-compatible" commands.
When either legacy-mode or legacy-path-cost control is toggled, all default path costs will be
recalculated to correspond to the new setting, and spanning tree is recalculated if needed.
