SET STP
Syntax
set stp [rstptype=normal|stpcompatible| [priority=

[forwarddelay=

] [default]
Parameters
rstptype
Sets the RSTP mode. The options are:
normal: The bridge uses RSTP. It transmits RSTP BPDU
packets, except on ports connected to bridges running STP.
This is the default setting.
stpcompatible: The bridge uses the RSTP parameter settings,
but transmits only STP BPDU packets from the ports. These
options are equivalent.
priority
Specifies the priority number for the bridge. This number is used in
determining the root bridge for RSTP. The bridge with the lowest
priority number is selected as the root bridge. If two or more
bridges have the same priority value, the bridge with the
numerically lowest MAC address becomes the root bridge. The
range is 0 to 61,440 in increments of 4,096, as shown in Table 39.
The default value is 32,768. If you enter a value that is not an
increment of 4096, the switch rounds the value down to the
previous increment.
