spanning-tree rstp mac-ush-threshold
Sets the threshold value to ush MAC addresses on RSTP instance.
Syntax
spanning-tree rstp mac-flush-threshold threshold-value
Parameters threshold-value—Enter the threshold value for the number of ushes, ranging from 0 to 65535. The default
value is 0.
Default Not congured
Command Mode CONFIGURATION
Usage Information The no version of this command removes the threshold value.
Example
OS10(config)# spanning-tree rstp mac-flush-threshold 255
Supported Releases 10.4.0E(R1) or later
spanning-tree rstp max-age
Congures the time period the bridge maintains conguration information before refreshing the information by recomputing the RSTP
topology.
Syntax
max-age seconds
Parameters seconds — Enter a maximum age value in seconds (6 to 40).
Default 20 seconds
Command Mode CONFIGURATION
Usage Information None
Example
OS10(config)# spanning-tree rstp max-age 10
Supported Releases 10.2.0E or later
spanning-tree rstp
Sets the priority value for RSTP.
Syntax
spanning-tree rspt priority priority value
Parameters priority priority value — Enter a bridge-priority value in increments of 4096 (0 to 61440). Valid priority
values are: 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864, 40960, 45056, 49152, 53248, 57344,
and 61440. All other values are rejected.
Default Not congured
Command Mode CONFIGURATION
Usage Information RSTP determines the root bridge but you can assign one bridge a lower priority to increase the probability it being
the root bridge. A lower priority value increases the probability of the bridge becoming a root bridge.
Example
OS10(config)# spanning-tree rstp priority 200
Supported Releases 10.2.0E or later
