To display STP settings, use the following command:
show stpd {<stpd_name>}
create stpd <stpd_name> Creates an STPD. When created, an STPD has
the following default parameters:
■
Bridge priority — 32,768
■
Hello time — 2 seconds
■
Forward delay — 15 seconds
enable ignore-stp vlan <name> Configures the switch to ignore the STP protocol,
and not block traffic for the VLAN(s). This
command is useful when multiple VLANs share
the same physical ports, but only some of the
VLANs require STP protection. The default
setting is disabled.
enable stpd {<stpd_name>} Enables the STP protocol for one or all STPDs.
The default setting is disabled.
enable stpd port {<portlist>} Enables the STP protocol on one or more ports.
If STPD is enabled for a port, Bridge protocol
Data Units (BPDUs) will be generated on that
port if STP is enabled for the associated STPD.
The default setting is enabled.
