NETGEAR 8800 Chassis Switch CLI Manual Usage Guidelines If your STPD has the same name as another component, for example a VLAN, NETGEAR recommends that you specify the identifying keyword as well as the name. If your STPD has a name unique only to that STPD, the keyword stpd is optional. MSTP STPDs use 802.1D BPDU encapsulation mode by default. To ensure correct operation of your MSTP STPDs, do not configure EMISTP or PVST+ encapsulation mode for MSTP STPDs. You can specify the following STP encapsulation modes: • dot1d-This mode is reserved for backward compatibility with previous STP versions. BPDUs are sent untagged in 802.1D mode. Because of this, any given physical interface can have only one STPD running in 802.1D mode. This encapsulation mode supports the following STPD modes of operation: 802.1D, 802.1w, and MSTP. • emistp-This mode sends BPDUs with an 802.1Q tag having an STPD ID in the VLAN ID field. This encapsulation mode supports the following STPD modes of operation: 802.1D and 802.1w. • pvst-plus-This mode implements PVST+ in compatibility with third-party switches running this version of STP. The STPDs running in this mode have a one-to-one relationship with VLANs, and send and process packets in PVST+ format. This encapsulation mode supports the following STPD modes of operation: 802.1D and 802.1w. Example The following command configures STPD s1 with PVST+ packet formatting for slot 2, port 1: configure stpd s1 ports mode pvst-plus 2:1 configure stpd ports port-priority configure stpd ports port-priority Description Specifies the port priority of the port in the specified STPD. Syntax Description stpd_name priority port_list Specifies an STPD name on the switch. Specifies a numerical port priority value. The range is 0 through 240 and is subject to the multiple of 16 restriction. Specifies one or more ports or slots and ports. 764 | Chapter 17. STP Commands
