Cisco Network Proposal Part 1: Springfield Device and STP Configurations

Springfield Site Device and STP Configurations

The Springfield site requirements are innovating device hostnames by implementing, banners and secure device passwords. These are all basic initial configurations that should be made prior to connecting the switch. Spanning-Tree Protocol prevents loops from forming when switches or bridges are interconnected. The advantages are that you can add another link between the switches or bridges that provides fault tolerance. The link can also provide port bundling that will increase the speed by twice its capacity. Whenever you are configuring spanning tree after the adding the additional link, it stops switching loop by making sure there is only one active path between the links. Switching loop will keep the circling around the network which can take down. Since the administrators are having some problems placing switch 1 as the root, there will be a reconfiguration to the spanning tree configurations. The mode best suited for the environment will be chosen. Also, there will a test of multiple security measures that can be implemented to protect the devices. Comment by Jeanette: Why? Don’t just make statements, explain why they are the basic initial configurations that should be made prior to connecting the switch? These have nothing to do with the switches operation so why do you think this? Comment by Jeanette: What do you mean by “the best mode suited for the environment will be chosen?

Device Configurations

To correctly word Message of the Day and login banners, it is best to consult with the legal department first before proceeding. Once the verbiage is approved and carefully considered, it can be implemented into these banners. Switch 2 is configured as the root. In order to fix the problem the administrators are having, there will need to be configuration of switch 1 by changing the priority number to force it to become the root switch. Comment by Jeanette: Why does someone need the MOTD? Why problem are the administrators having?

Currently PVST is enabled on switches 1, 3 and 4 while Switch 2 has RSTP enabled. Spanning tree protocol will be changed on switches 1, 3 and 4 from the default mode of PVST to RSTP in order to take advantage of the benefits of RSTP. RSTP improves processing times by using port roles, using a method of sending messages between bridges on designated ports, calculating alternate paths, and using faster timers. This feature ensures that a bridging loop cannot form, because the switch's shutting down the port removes the possibility for a loop forming. Root guard is a feature that will be enabled to prevent unauthorized switches from becoming the root bridge. Uplink Fast will be disabled because RSTP has a similar function built into it that will work the same. Comment by Jeanette: Way too many acronyms! Don’t assume that your reader will know what these acronyms mean Comment by Jeanette: Don’t spend a lot of time providing definitions about these protocols, this is probably why your Turnitin grade is so high. Why are you recommending that the admins implement change from PVST to RSTP? Which of the identified problems will this fix.

Message of the Day banner: Comment by Jeanette: You have not provided any explanation of Banner MOTD, what value it will provide the Admins.

Springfield – Switch1 >enable

Springfield – Switch1 #configure terminal

Springfield – Switch1 (config)#banner motd

Unauthorized Use or Access Prohibited: You must have permission to access or configure this device. All activities performed on this device may be logged, and violations of this policy may result in disciplinary action, and| may be reported to law enforcement authorities. There is no right to privacy on this device.# [4] Comment by Jeanette: Banner MOTD requires delimiters to indicate the beginning and end of a Banner. Where are your delimiters? This is something you would to explain to your readers.

Springfield – Switch1 (config)#exit

Springfield – Switch1#copy run start

Login banner: Comment by Jeanette: What’s the difference between a Banner MOTD and a Login Banner and why would the Admins want to use 1 or both at the same time?

Springfield – Switch1>enable

Springfield – Switch1#conf t

Springfield – Switch1(config)#banner login # Only administrators are allowed access. Please login now.#

Springfield – Switch1(config)#exit

Springfield – Switch1#copy run start

Implementing device passwords on both console port and VTY: Comment by Jeanette: Don’t assume that the reader will know that your are configuring Telnet. You don’t provide any explanations for these configurations. Why do the admins want to configure Telnet?

Springfield – Switch1>enable

Springfield – Switch1#configure terminal

Springfield – Switch1 (config)#line con 0

Springfield – Switch1 (config-line)#password $UpeR$eCrEt

Springfield – Switch1 (config-line)#login

Springfield – Switch1 (config-line)#line vty 1

Springfield – Switch1 (config-line)#password $UpeR$eCrEt

Springfield – Switch1 (config-line)#login

Springfield – Switch1 (config-line)#exit

Springfield – Switch1 (config)#service password-encryption

Springfield – Switch1 (config)#exit

Implementing RSPT on the switch:

Springfield – Switch1>enable

Springfield – Switch1#conf t

Springfield – Switch1(config)#spanning-tree mode rapid-pvst

Springfield – Switch1(config)#spanning-tree vlan 1 priority 4096

Springfield – Switch1(config)#no spanning-tree uplinkfast

Springfield – Switch1(config)#int range gi0/1 – 2

Springfield – Switch1(config-if)#spanning-tree guard root

Springfield – Switch1(config)#int range gi0/96

Springfield – Switch1(config-if)#spanning-tree bpduguard enable

Springfield – Switch1(config)#end

Springfield – Switch1#copy run start
