The above command to save the configuration can also be accomplished with copy run start Ports 1-2 are assigned to VLAN2 and ports 3-4 to VLAN3ДЄccess-switch1(config)# interface range fa 0/1-2ДЄccess-switch1(config-if-range)#В switchport mode accessДЄccess-switch1(config-if-range)# switchport access vlan 2ДЄccess-switch1(config)# interface range fa 0/3-4ДЄccess-switch1(config-if-range)# switchport access vlan 3 ! Now assign the physical ports to each VLAN. ! First create the Layer2 VLANs on the switchДЄccess-switch1(config-vlan)# name TEACHERSДЄccess-switch1(config-vlan)# name STUDENTS LetвЂ™s create two new vlans (VLAN2 and VLAN3) and assign two ports to each one. In order to do the above Layer2 segmentation you need to create additional VLANs from the default VLAN1 and then assign physical ports to these new vlans. One of the most important functions of an Ethernet switch is to segment the network into multiple Layer2 VLANs (with each VLAN belonging to a different Layer3 subnet). STEP9: Configure Layer2 VLANs and assign ports to the themД«y default, all physical ports of the switch belong to the native VLAN1. ! Assume that we have a 48-port switch and we donвЂ™t need ports 25 to 48ДЄccess-switch1(config)# interface range fa 0/25-48ДЄccess-switch1(config-if-range)# shutdown ! This step is optional but enhances security STEP8: Disable unneeded ports on the switch STEP7: Assign default gateway to the switchДЄccess-switch1(config)# ip default-gateway 10.1.1.254 !Management IP is assigned to Vlan 1 by defaultДЄccess-switch1(config-if)# ip address 10.1.1.200 255.255.255.0 STEP6: Assign IP address to the switch for management !Apply the access list to Telnet VTY LinesДЄccess-switch1(config-line)# access-class TELNET-ACCESS in STEP5: Define which IP addresses are allowed to access the switch via TelnetДЄccess-switch1(config)# ip access-list standard TELNET-ACCESSДЄccess-switch1(config-std-nacl)# permit 10.1.1.100ДЄccess-switch1(config-std-nacl)# permit 10.1.1.101

#REBOOT CISCO SWITCH PASSWORD#

Although it is much better to configure an external AAA server (for centralized Authentication Authorization and Accounting), in this article we will just configure a password on each access line (VTY lines for Telnet and Console line):ДЄccess-switch1(config-line)# password strongtelnetpassДЄccess-switch1(config-line)# password strongconsolepass It is a very good security practice to lock-down all access lines of a switch with a password. STEP4: Configure a password for Telnet and Console access The password above will be used to enter into Privileged EXEC mode as described in Step 1 above. STEP3: Configure an administration password (enable secret password)ДЄccess-switch1(config)# enable secret somestrongpass STEP2: Set up a hostname for the particular switch to distinguish it in the network See Step 3 below about setting up a password for the Privileged EXEC mode.

Note: The switch will not ask you for a password when entering into Privileged EXEC mode (i.e after typing вЂњenableвЂќ) if it has the default factory configuration. You will get into privileged EXEC mode (вЂњ Switch#вЂќ) You will get the initial command prompt вЂњ Switch>вЂќ

Use a terminal emulation software such as PuTTY and connect to the console of the switch. I donвЂ™t like graphical GUI or web management at all, so I will show you command line configuration (CLI) which is much more powerful and actually forces the administrators to learn what they are doing on the device. In this article I will describe the basic steps needed to configure and setup a Cisco switch from scratch. Unlike other lower class switch vendors (which are plug-and-play), the Cisco switch needs some initial basic configuration in order to enable management, security and some other important features.

Versatile, reliable, flexible and powerful, the Cisco switch product line (such as the 2960, 3560, 3650, 3850, 4500, 6500, 9400 series etc) offer unparalleled performance and features.ДЄlthough a Cisco switch is a much simpler network device compared with other devices (such as routers and firewalls for example), many people have difficulties to configure a Cisco Catalyst Switch. In my opinion, the Cisco switches are the best in the market.
