Lab 2.1: Subnet Design

Summary

In this lab we setup a Packet Tracer file with the network shown below in the Subnet Table. During this lab we learned how to setup access and trunk ports from the CLI as well how to configure multiple ports at once. this lab also gave insight into how intervlan communication works at a Multilayer Switch.

Subnet Table

VLAN	VLAN_NAME	Hosts Needed	Network	Netmask	Router Address
200	StuWireless	900	10.8.0.0	/22	10.8.0.1
210	FSWireless	650	10.8.4.0	/22	10.8.4.1
110	Student	450	10.8.8.0	/23	10.8.8.1
1	Management	250	10.8.10.0	/24	10.8.10.1
100	FacStaff	200	10.8.11.0	/24	10.8.11.1
130	StuLab1	35	10.8.12.0	/26	10.8.12.1
140	StuLab2	35	10.8.12.64	/26	10.8.12.65

Commands to navigate different modes on a Cisco Switch/Router (enable, config t…) and how you know what mode you are in

• If terminal reads Router> type enable to enter Router#
  • Under Router> you’re allowed to do ping, show, enable, etc...
• If terminal reads Router# type config to enter Router(config)#
  • Under Router# you’re allowed to do all User EXEC Commands, debug commands, reload, configure(config), etc...
• If terminal reads Router(config)# view the Official Guide because config branches into 3 different sections.
  • Under Router(config)# you’re allowed to do hostname, enable secret, ip route, interface (ethernet, serial, bri, etc...), router (rip, ospf, igrp, etc...), line (vty, console, etc...)
• Official Cisco Guide (Below is image and table included on the website)

EXEC Mode	Description
Router>	- User EXEC mode
Router#	- Privileged EXEC mode
Router(config)#	- Configuration mode (notice the # sign indicates this is accessible only at privileged EXEC mode)
Router(config-if)#	- Interface level within configuration mode
Router(config-router)#	- Routing engine level within configuration mode
Router(config-line)#	- Line level (vty, tty, async) within configuration mode

Commands to create VLANS on switch

Switch(config)# vlan 100 
Switch(config-vlan)# name student

Setting access and trunk ports on switch

• For this to work you must select an interface using Switch(config)# interface range FastEthernet 0/{port}
• For an individual port type Switch(config-if)# switchport 'access or trunk' vlan {port}
• Configure interfaces in “ranges”
  • in ‘Config’ mode type Switch(config)# interface range FastEthernet 0/{start port}-{stop port}

IP Routing

• To turn on routing on multilayer switch type Router(config)ip routing
• To enter vlan mode Router(config) interface vlan 100
• To set the ip address and subnet for vlan 100 Router(config-if) ip address {ip} {subnet}

Side Notes

• side note you can cut down writing if it’s within the ball park. The two below do the same thing.
  • Switch(config)# interface range FastEthernet 0/{start port}-{stop port}
  • Switch(config)# inter rang FastEthernet 0/{start port}-{stop port}
