Spanning-Tree Commands spanning-tree mst mstp-rstp The spanning-tree mst mstp-rstp interface configuration command configures the port to convert RSTP packets to MSTP instances. Use the no form of this command to disable this feature. When interoperating with switches that do not support or are not configured for Per VLAN Spanning-Tree (PVST/PVST+) disable this feature and configure the HP PC Blade switch to use the matching IEEE standard Spanning-Tree Protocol mode. . When MSTP-to-RSTP is enabled (enabled by default), attempting to put any switch port into trunk or general mode will cause the following error message: Port , extension separated-bridge exist. This feature does not support VLAN Trunking (a.k.a VLAN Tagging). Syntax spanning-tree mst mstp-rstp no spanning-tree mst mstp-rstp Parameters This command has no arguments or keywords. Default Setting Enabled. Command Modes Global Configuration mode Command Usage This feature can only be enabled when the switch is configured for spanning-tree mode mstp. This is a non-standard feature that maps an individual PVST instance [e.g., Cisco PVST/PVST+ or Rapid PVST/PVST+] to an individual MSTP instance over a statically assigned VLAN. Ingress BPDUs are handled by the internal MSTP instance for which the participating static VLAN switch port is assigned. The egress Spanning-Tree BPDU will have a bridge ID composed of the configured priority for the switch multiplied by 4096, plus the VLAN ID assigned to the egress port, concatenated to the bridge MAC address. By default, all external switch port egress IEEE 802.1w BPDUs. If the port encounters a legacy IEEE 802.1D BPDU, the conversion process will communicate with the legacy version. For this feature to work as expected, only one VLAN can be assigned to each switch port on both the upstream and downstream switch. Since the switch ports are Access mode, the VLANs on each side of the link do not need to have the same VLAN ID. If desirable, the VLAN assigned to the HP PC Blade Switch can be changed so that its ID matches the VLAN ID of the upstream switch. HP PC Blade Switch CLI Reference Guide www.hp.com 22-39
