Which command is used to change priority STP?

switch(config)#spanning-tree vlan vlan-id priority priority – Sets the switch priority. The default is 32768, so any value lower than that will render the switch root. It is advisable to make use of the earlier commands instead of this one. switch(config)#end – It is used to exit the configuration mode.

How do I change the priority of a switch?

How do users change the priority value? From the global configuration mode, issue the command switch stack-member-number priority new-priority-value. From the Bootloader switch: prompt, issue the command set SWITCH_PRIORITY new-priority-value.

What is the default spanning-tree priority?

The default is 32768. The lower the number the more likely the switch will be chosen as the root switch. Valid priority values are multiples of 4096. Spanning-tree priority xxx configures the priority in RSTP if RSTP is running, or configures the CIST priority if MSTP is running.

How do I change the priority of a Cisco switch?

Switch Stack Configuration Scenarios

  1. Connect two switches through their StackWise ports.
  2. Use the switch stack-member-number priority new-priority-number command to set one stack member with a higher member priority value.
  3. Restart both stack members at the same time.

What is STP configuration?

The Spanning Tree Protocol (STP) is defined by IEEE standard 802.1D-1988. The STP generates a single spanning tree inside a network. Such mode proved to be useful for supporting applications and protocols in which frames are delivered out of sequence or as duplicates.

What is spanning tree Portfast command?

Portfast feature causes a switch port to enter the spanning tree forwarding state immediately, bypassing the listening and learning states.

What is STP in CCNA?

Spanning Tree Protocol (STP) is a network protocol designed to prevent layer 2 loops. It is standardized as IEEE 802. D protocol. STP blocks some ports on switches with redundant links to prevent broadcast storms and ensure loop-free topology.

How do I check my spanning tree Portfast?

To view the configured Spanning Tree PortFast enabled ports, run the “show running-config” IOS command as shown below. We can see that PortFast is enabled on access ports fa0/1 to fa0/24. To display a detailed summary of interface information, run “show spanning-tree detail” command as shown below.
