Assigns an StpdID to an STPD.
| stpd_name | Specifies an STPD name on the switch. |
| stpd_tag | Specifies the VLAN ID of the carrier VLAN that is owned by the STPD. |
N/A.
If your STPD has the same name as another component, for example a VLAN, we recommend 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.
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.
An STPD ID is used to identify each STP domain. You assign the StpdID when configuring the domain. An STPD ID must be identical to the VLAN ID of the carrier VLAN in that STP domain, and that VLAN cannot belong to another STPD. Unless all ports are running in 802.1D mode, an STPD with ports running in either EMISTP mode or PVST+ mode must be configured with an STPD ID.
You must create and configure the VLAN, along with the tag, before you can configure the STPD tag. To create a VLAN, use the create vlan command. To configure the VLAN, use the configure vlan commands.
MSTP uses two different methods to identify the STPDs that are part of the MSTP network. An instance ID of 0 identifies the CIST. The switch assigns this ID automatically when you configure the CIST STPD. To configure the CIST STPD, use the configure stpd stpd_name mode [dot1d | dot1w | mstp [cist | mstiinstance]] command.
An MSTI identifier (MSTI ID) identifies each STP domain that is part of an MSTP region. You assign the MSTI ID when configuring the STPD that participates in the MSTP region. Each STPD that participates in a particular MSTP region must have the same MSTI ID. To configure the MSTI ID, use the configure stpd stpd_name mode [dot1d | dot1w | mstp [cist | mstiinstance]] command.
The following example assigns an StpdID to the purple_st STPD:
configure stpd purple_st tag 200
This command was first available in ExtremeXOS 10.1.
This command is available on all Universal switches supported in this document.
