NEC N8406-022 manual Spanning Tree configuration, spanning-treestp <1-32>vlan, <1-4095>, enable

Spanning Tree configuration

The switch supports the IEEE 802.1d Spanning Tree Protocol (STP) and Cisco proprietary PVST and PVST+ protocols. You can configure up to 31 spanning tree groups on the switch (STG 32 is reserved for switch management). Spanning Tree is turned on by default.

NOTE: When RSTP is turned on, only STP group 1 can be configured.

The following table describes the Spanning Tree Configuration commands.
