The Configure RSTP Bridge Parameters tab is shown in Figure 131.
Figure 131. Configure RSTP Parameters Tab (Configuration)
5. Configure 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 6 on page 306.
