NETGEAR 8800 Chassis Switch CLI Manual configure stpd add vlan configure stpd add vlan ports [all | ] {[dot1d | emistp | pvst-plus]} Description Adds all ports or a list of ports within a VLAN to a specified STPD. Syntax Description stpd_name vlan_name all port_list dot1d emistp pvst-plus Specifies an STPD name on the switch. Specifies a VLAN name. Specifies all of the ports in the VLAN to be included in the STPD. Specifies the port or ports to be included in the STPD. Specifies the STP encapsulation mode of operation to be 802.1D. Specifies the STP encapsulation mode of operation to be EMISTP. Specifies the STP encapsulation mode of operation to be PVST+. Default Ports in the default STPD (s0) are in dot1.d mode. Ports in user-created STPDs are in emistp mode. Usage Guidelines To create an STP domain, use the create stpd command. To create a VLAN, use the create vlan command. In an EMISTP or PVST+ environment, this command adds a list of ports within a VLAN to a specified STPD provided the carrier VLAN already exists on the same set of ports. You can also specify the encapsulation mode for those ports. In an MSTP environment, you do not need a carrier VLAN. A CIST controls the connectivity of interconnecting MSTP regions and sends BPDUs across the regions to communicate region status. You must use the dot1d encapsulation mode in an MSTP environment. You cannot configure STP on the following ports: • Mirroring target ports • Software-controlled redundant ports If you see an error similar to the following: Error: Cannot add VLAN default port 3:5 to STP domain You might be attempting to add: • A carrier VLAN port to a different STP domain than the carrier VLAN belongs 746 | Chapter 17.
