M4300 Intelligent Edge Series Fully Managed Stackable Switches The options are IEEE 802.1d, IEEE 802.1w, IEEE 802.1s, PVST, and RPVST. 7. Use Configuration Name to specify an identifier used to identify the configuration currently being used. It can be up to 32 alphanumeric characters. 8. Use Configuration Revision Level to specify an identifier used to identify the configuration currently being used. The values allowed are between 0 and 65535. The default value is 0. 9. Select the Forward BPDU while STP Disabled Disable or Enable radio button. This specifies whether spanning tree BPDUs are forwarded or not while spanning-tree is disabled on the switch. 10. Select the BPDU Guard Disable or Enable radio button. This specifies whether the BPDU guard feature is enabled. The STP BPDU guard allows a network administrator to enforce the STP domain borders and keep the active topology consistent and predictable. The switches behind the edge ports with STP BPDU guard enabled do not influence the overall STP topology. At the reception of BPDUs, the BPDU guard operation disables the port that is configured with this option and transitions the port into disable state. This would lead to an administrative disable of the port. 11. Select the BPDU Filter Disable or Enable radio button. This specifies whether the BPDU Filter feature is enabled. STP BPDU filtering applies to all operational edge ports. Edge Port in an operational state is supposed to be connected to hosts that typically drop BPDUs. If an operational edge port receives a BPDU, it immediately loses its operational status. In that case, if BPDU filtering is enabled on this port then it drops the BPDUs received on this port. 12. Select the e Fast Backbone Mode Disable or Enable radio button. (PVSTP only.) Use this option to choose a new indirect link when an indirect link fails. The system does not ignore inferior BPDUs, as is done in 802.1d. Rather the system uses the BPDUs to age out on the port it received the BPDUs. Later the system sends out root link queries on other non-designated ports. Based on the replies, if there is a positive response to at least one of them, it chooses a new indirect link. Fast Backbone mode is disabled by default. 13. Select the Fast Uplink Mode Disable or Enable radio button. (PVSTP only.) This option reduces the recovery time in selecting a new root port when the primary root port goes down. Fast Uplink mode is disabled by default. 14. Use the Max Update Rate field to configure the Fast Uplink Maximum Update Rate. This field is enabled for configuration when Fast Uplink mode is enabled. Allowed values are 0 to 32000 packets per second. The default value is 150. 15. Click the Apply button. Your settings are saved. Configure Switching Information 215 User Manual
