ENABLE STP
Syntax
ENABLE STP [ {
[ INSTANCE={ stpname | mstid | MAIN | ALL }
INTERFACE={ type:id-range | id-range | ifname-list | ALL } [ {
TOPOLOGYCHANGE | RSTPCHECK } ] ] |
[ INTERFACE={ type:id-range | id-range | ifname-list | ALL } [ {
TOPOLOGYCHANGE | RSTPCHECK } ] ] }
Description Used to enable Spanning Tree Protocol operations for the system. When this command
is issued, all interfaces in the system that have not been identified by the user to be
excluded from STP operations are processed by the Spanning Tree Protocol algorithm
(see DISABLE STP for information on interface exclusion from STP operations).
Options The following table gives the range of values for each option that can be specified with
this command and a Default Value (if applicable).
Example (Enable stp and show the all of the interfaces included)
enable stp
Info (010017): Operation Successful
show stp inst all
--- STP Information ------------------------------------------------------------
Spanning Tree Type...................... MSTP (CIST)
Instance Name......................... MAIN (0)
Instance State........................ ENABLED
Root Bridge ID Priority................. 0
Option Description Default Value
INSTANCE The instance to be enabled.
INTERFACE The interface(s) on which STP will be enabled.
RST-
PCHECK
The interface can be forced to go for migration
check. This parameter is functional only in the
RSTP and STP_COMPATIBLE_RSTP operational
mode
.
TOPOLO-
GYCHANGE
Controls the detection of topology changes on the
associated port. This allows the disabling of topology
change detection on ports that are known to be con-
nected to single end stations that could cause the Topol-
ogy Change Notification mechanism to be triggered for
the entire network when the end station is power
cycled.
