8 MSTP Configuration
The priority of S9300B in the CIST is lower than that of S9300A; therefore, GE 6/0/2 of S9300B
functions as the root port in the CIST. S9300A and S9300B belong to different regions; therefore,
GE 6/0/2 of S9300B functions as the master port in MSTI1. In MSTI1, the priority of S9300B
is lower than that of S9300D; therefore, GE 6/0/1 of S9300B functions as the root port. The
priority of S9300B in the CIST is higher than that of S9300B; therefore, GE 6/0/1 of S9300B
functions as the designated port in the CIST.
# Run the display stp interface brief commands on S9300D. The displayed information is as
follows:
<S9300D> display stp interface GigabitEthernet 2/0/1 brief
MSTID
<S9300D> display stp interface GigabitEthernet 1/0/2 brief
MSTID
On S9300D, GE 1/0/2 functions as the alternate port in the CIST. S9300D and S9300C are in
different regions; therefore, GE 1/0/2 of S9300D also functions as the alternate port in MSTI1.
GE 2/0/1 of S9300D is the root port in the CIST. The priority of S9300D is higher than that of
S9300B in MSTI1; therefore, GE 2/0/1 also functions as the designated port in MSTI1.
