●
Revision Level—This number is reserved for future use.
●
Common and Internal Spanning Tree (CIST)—The name of the CIST that controls the connectivity of
interconnecting MSTP regions.
●
Total number of MST Instances (MSTI)—The number of MSTIs running in the MSTP region.
If you use the
show stpd
command and specify the name of an STPD, in addition to the data
previously described, the command displays more detailed information about the STPD. If you specify
the
detail
option, the switch displays the same type of information for all of the STPDs configured on
the switch.
The additional output includes the following:
●
STPD mode of operation
●
Autobind mode
●
Active VLANs
●
Timer information
●
Topology change information
If you have MSTP configured, the command also displays the following information:
●
Bridge role
●
CIST root
●
CIST regional root
●
MSTI instances
●
Master port (Displayed only on MSTI STPDs)
If your STPD has the same name as another component, for example a VLAN, Extreme Networks
recommends that you specify the identifying keyword as well as the name. If you do not specify the
stpd
keyword, an error message similar to the following is displayed:
%% Ambiguous command: "show Test"
In this example, to view the settings of the STPD
Test
, enter
show stpd Test
.
If your STPD has a name unique only to that STPD, the keyword
stpd
is optional.
Example
The following command displays the STPD settings on a switch that has MSTP configured:
