Command Description
create stpd 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 stpd [ | all] Enables the STP protocol for one or all STPDs.
The default setting is disabled.
enable stpd port Enables the STP protocol on one or more ports.
If STPD is enabled for a port, BPDUs will be
generated on that port if STP is enabled for the
associated STPD. The default setting is enabled.
config stpd add vlan Adds a VLAN to the STPD.
config stpd hellotime Specifies the time delay (in seconds) between
the transmission of BPDUs from this STPD when
it is the Root Bridge.
The range is 1 through 10. The default setting is
2 seconds.
config stpd forwarddelay
Specifies the time (in seconds) that the ports in
this STPD spend in the listening and learning
states when the switch is the Root Bridge.
The range is 4 through 30. The default setting is
15 seconds.
config stpd maxage Specifies the maximum age of a BPDU in this
STPD.
The range is 6 through 40. The default setting is
20 seconds.
Note that the time must be greater than, or equal
to 2 X (Hello Time + 1) and less than, or equal to
2 X (Forward Delay –1).
config stpd priority Specifies the priority of the STPD. By changing
the priority of the STPD, you can make it more or
less likely to become the Root Bridge.
The range is 0 through 65,535. The default
setting is 32,768. A setting of 0 indicates the
