Users Guide

Usage Information Dell EMC recommends increasing the hello-time for large congurations, especially congurations with multiple
ports.
Example
OS10(config)# spanning-tree vlan 10 hello-time 5
Supported Releases 10.2.0E or later
spanning-tree vlan mac-ush-threshold
Congures the MAC-ush threshold value for the specied VLAN.
Syntax
spanning-tree vlan vlan-id mac-flush-threshold threshold-value
Parameters
• vlan-id — Enter the spanning-tree VLAN ID number, from 1 to 4093.
• threshold-value—Enter the threshold value for the number of ushes, from 0 to 65535. The default
value is 5.
Default Not congured
Command Mode CONFIGURATION
Usage Information The threshold value indicates the number of port-based ush requests allowed to be invoked before starting the
ush optimization. When the ush interval value is non-zero, port-and-instance-based ushing is triggered until the
threshold is reached. Once the threshold is reached, MAC-ush timer starts. On timer expiry, the system triggers
VLAN-based ushing. When the timer is running, any port-and-vlan-based ushing is suppressed. The no form of
the command resets the ush indication threshold of the specic instance to its default value.
Example
OS10(config)# spanning-tree vlan 100 mac-flush-threshold 255
Supported Releases 10.4.0E(R1) or later
spanning-tree vlan max-age
Congures the time period the bridge maintains conguration information before refreshing the information by recomputing RPVST.
Syntax
spanning-tree vlan vlan-id max-age seconds
Parameters max-age seconds — Enter a maximum age value in seconds, from 6 to 40.
Default 20 seconds
Command Mode CONFIGURATION
Usage Information None
Example
OS10(config)# spanning-tree vlan 10 max-age 10
Supported Releases 10.2.0E or later
spanning-tree vlan priority
Sets the priority value for RPVST+.
Syntax
spanning-tree vlan vlan-id priority priority value
Parameters priority priority value — Enter a bridge-priority value in increments of 4096, from 0 to 61440. Valid
priority values are: 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864, 40960, 45056, 49152, 53248,
