Configuring the CIST
Configure an STPD as the
CIST, specifying the mstp cist keywords in the
following command:
configure
stpd stpd_name
mode [dot1d | dot1w | mstp [cist | msti
instance]]
You can enable MSTP on a per STPD basis only. By specifying the mstp cist keywords, you can configure the mode of operation for the STPD as MSTP and identify the STPD to be the CIST.
