NETGEAR 8800 Chassis Switch CLI Manual You should not configure any STP parameters unless you have considerable knowledge and experience with STP. The default STP parameters are adequate for most networks. By changing the priority of the port, you can make it more or less likely to become the root port or a designated port. A setting of 0 indicates the highest priority. The range for the priority parameter is 0 through 31 for STP and 0 through 15 for MSTP and RSTP. NETGEAR 8800 introduces support for a new ports priority command: configure stpd ports port-priority. The priority range of this command is 0 through 240 and is subject to the multiple of 16 restriction. For more information see configure stpd ports port-priority on page 764. Example The following command assigns a priority of 1 to slot 2, ports 1 through 5 in STPD s0: configure stpd s0 ports priority 1 2:1-2:5 configure stpd ports restricted-role disable configure stpd ports restricted-role disable Description Disables restricted role on the specified port inside the core network. Syntax Description stpd_name port_list Specifies an STPD name on the switch. Specifies one or more ports or slots and ports. Default NA Usage Guidelines The restricted role is disabled by default. If set, it can cause a lack of spanning tree connectivity. A network administrator enables the restricted role to prevent bridges external to a core region of the network from influencing the spanning tree active topology, possibly because those bridges are not under the full control of the administrator. Note: Disabling Restricted Role at CIST is inherited by all MSTI. 766 | Chapter 17. STP Commands
