NETGEAR AV Line M4250 GSM4210PX 8-Port Gigabit PoE+ Compliant Managed AV Switch with SFP (220W) - Manual (Page 227)

This specifies whether spanning tree operation is enabled on the switch.
7. Select one of the following Force Protocol Version radio buttons to specify the STP
version that the switch must use:
• IEEE 802.1d: Traditional (classic) Spanning Tree Protocol.
• IEEE 802.1w: Rapid Spanning Tree Protocol.
• IEEE 802.1s: Multiple Spanning Tree Protocol.
• PVST: Per-VLAN Spanning Tree Protocol.
• RPVST: Rapid Per-VLAN Spanning Tree Protocol.
8. In the Configuration Name field, specify an ID or name that lets you identify the
configuration.
The name can be up to 32 characters. The default is the MAC address of the switch.
9. In the Configuration Revision Level field, specify an ID that lets you identify the
configuration.
For example, if you change the configuration, you can change the ID in the
Configuration Revision Level field so you can keep track of the different
configurations. You can enter an ID from 0 to 65535. The default is 0.
10. Select one of the following Forward BPDU while STP Disabled radio buttons:
• Disabled: Spanning tree BPDUs are not forwarded if spanning-tree is disabled
on the switch. The default is Disable.
• Enabled: Spanning tree BPDUs are forwarded if spanning-tree is disabled on the
switch.
11. Select one of the following BPDU Guard radio buttons:
• Disabled: The BPDU guard feature is disabled, which is the default setting.
• Enabled: The BPDU guard feature is enabled and enforces the STP domain
borders to keep the active topology consistent and predictable. Switches behind
edge ports on which STP BPDU guard is enabled do not affect the overall STP
topology. At the reception of BPDUs, the port on which BPDU guard is enabled
transitions into disabled state.
12. Select one of the following BPDU Filter radio buttons:
• Disabled: The BPDU Filter feature is disabled, which is the default setting.
• Enabled: The BPDU Filter feature is enabled and applies to all operational edge
ports. An edge port in an operational state connects to hosts that typically drop
BPDUs. If an operational edge port receives a BPDU, it loses its operational status.
If a port on which BPDU filtering is enabled receives BPDUs, the port drops the
BPDUs and remains operational.
