Switching disable mstp cist port 8-109
Software Release 2.7.3
C613-03098-00 REV A
disable mstp
Syntax DISable MSTp
Description This command disables the multiple spanning tree operation on the switch. By
default MSTP is disabled on switch start-up. This command overrides the
following commands:
enable mstp cist port
disable mstp cist port
enable mstp msti port
disable mstp msti port
Once MSTP has been disabled, no port for the CIST or MSTIs can be enabled or
disabled. MSTP must be disabled before any STP instances can be enabled.
Examples To enable MSTP, use the commands:
dis mst
Related Commands enable mstp
show mstp
disable mstp cist port
Syntax DISable MSTp CIST POrt={port-list|ALL}
where port-list is a port number, range (specified as n-m), or comma-separated
list of port numbers and/or ranges. Port numbers start at 1 and end at m,
where m is the highest numbered Ethernet switch port, including uplink ports.
Description This command disables operation of the Multiple Spanning Tree algorithm on
specific ports or all ports for the Common Internal Spanning Tree. Disabled
ports are placed in a discarding state and cannot forward frames. All of the
ports are enabled for the CIST by default.
The mstp module must be enabled first before any port for the CIST can be
enabled or disabled.
The port parameter specifies a list of ports to be disabled for the CIST. If all is
specified, all of the ports on the switch will be disabled for the CIST. If the
command would succeed on a subset of the ports specified, but cause an error
on the others, then the command as a whole will fail and have no effect.
Example To disable port 2 in the CIST, use the command:
disable mstp cist port=2
Related Commands show mstp msti
show mstp cist port
