How do I set up RSTP?

How do I set up RSTP?

To enter RSTP settings: STEP 1 Click Spanning Tree > STP Status and Global Settings. STEP 2 Enable RSTP. STEP 3 Click Spanning Tree > RSTP Interface Settings.

Which process is used during RSTP convergence?

Synchronization. To participate in RSTP convergence, a switch must decide the state of each of its ports. Nonedge ports begin in the Discarding state. After BPDUs are exchanged between the switch and its neighbor, the Root Bridge can be identified.

What is the best method of ensuring that your preferred switch is the root bridge?

The switch with the lowest priority, which means lowest BID, becomes the root bridge (the lower the priority value, the higher the priority). For example, to ensure that a specific switch is always the root bridge, you set the priority to a lower value than the rest of the switches on the network.

What is the difference between STP and RSTP?

Unlike STP, which has five switchport states, RSTP has only three: discarding, learning, and forwarding….Comparing STP and RSTP Port States.

STP	RSTP
Blocking	Discarding
Listening	Discarding
Learning	Learning
Forwarding	Forwarding

When should I enable RSTP?

RSTP determines the root bridge, but you can assign one bridge a lower priority to increase the likelihood that it is selected as the root bridge. To change the bridge priority, use the following command….

Command	Purpose
console (conf-if-te-0/1)# no spanning-tree rstp edge-port	Disables Edge-port on the interface.

How does RSTP work?

RSTP works by adding an alternative port and a backup port compared to STP. These ports are allowed to immediately enter the forwarding state rather than passively wait for the network to converge. The alternative port moves to the forwarding state if there is a failure on the designated port for the segment.

What is RSTP convergence time?

When default values are used for the maximum age (20 seconds) and forward delay (15 seconds), it takes 50 seconds for the device to converge. RSTP converges faster because it uses a handshake mechanism based on point-to-point links instead of the timer-based process used by STP.

What does R in RSTP stand for?

Rating. RSTP. Rapid Spanning Tree Protocol. Computing » Networking — and more…

What is bridge priority?

The bridge priority determines which bridge is elected as the root bridge. If two bridges have the same path cost to the root bridge, the bridge priority determines which bridge becomes the designated bridge for a LAN segment.

How does a switch prevent loops?

When a new switch is introduced to the network, the spanning tree algorithm and port states are recalculated to prevent a loop. Switches communicate with Bridge Protocol Data Units (BPDU), which are frames that contain information about STP, every two seconds.

Should I enable RSTP?

It is recommended that RSTP be enabled on all ports. RSTP may be disabled at the port level. Disabling RSTP on a port removes the port from any STP processing including any STP guard configuration. Disabling RSTP on a port is not recommended unless the client device connected to the port is incompatible with STP.

What are the five Spanning Tree Protocol states?

The ports on a switch with enabled Spanning Tree Protocol (STP) are in one of the following five port states.

• • Blocking.
• • Listening.
• • Learning.
• • Forwarding.
• • Disabled.

Which is better RSTP or spanning tree protocol?

Both STP or RSTP are critical to having a healthy network and an administrator would benefit from using RSTP over STP. RSTP is the answer for businesses that require faster recovery times.

How many switch ports does RSTP have compared to STP?

Unlike STP, which has five switchport states, RSTP has only three: discarding, l earning, and forwarding. Disabled – The result of an administrative command that will disable the port.

Which is the discarding state in RSTP protocol?

In RSTP the disabled, listening and blocking port states are replaced with just one state called the Discarding state: Forwarding – port participates in traffic forwarding and is learning MAC addresses, is receiving BPDUs (forwarding=yes). Learning – port does not participate in traffic forwarding but is learning MAC addresses (learning=yes).

How old is the Spanning Tree Protocol ( STP )?

STP is a very old protocol and has a convergence time (the time needed to fully learn network topology changes and to continue properly forwarding traffic) even up to 50 seconds, which was acceptable for the 1980s when it was invented.
