The Configure RSTP Bridge Parameters tab is shown in Figure 57.
Figure 57. Configure RSTP Parameters Tab (Configuration)
5. Adjust the following parameters as necessary.
Force Version
This selection determines whether the bridge operates with RSTP
or in an STP-compatible mode. If you select RSTP, the bridge
operates all ports in RSTP, except for those ports that receive STP
BPDU packets. If you select Force STP Compatible, the bridge
operates in RSTP, using the RSTP parameter settings, but it sends
only STP BPDU packets out the ports.
Bridge Priority
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. When
a root bridge goes off-line, the bridge with the next priority
number automatically takes over as the root bridge. This
parameter can be from 0 (zero) to 61,440 in increments of 4096,
with 0 being the highest priority. For a list of the increments, refer
to Table 5 on page 168.
