Setting up an access switch involves connecting to the device, configuring basic parameters, securing access, creating VLANs, and assigning ports.

Step 1: Connect to the Switch

Use a console cable to connect your computer to the switch. Launch a terminal emulator like PuTTY, select the Serial connection type, specify the COM port, and set the baud rate (commonly 115200 for Cisco 300/500 series) to access the CLI .

Step 2: Enter Privileged EXEC Mode

At the prompt, type enable to enter Privileged EXEC mode (Switch#). This mode allows you to execute configuration commands .

Step 3: Set Hostname

Assign a unique hostname to identify the switch in the network:

Switch(config)# hostname AccessSwitch1

This helps in managing multiple switches .

Step 4: Configure Passwords

Set a strong enable secret password for Privileged EXEC mode:

AccessSwitch1(config)# enable secret YourStrongPassword

Also, secure console and VTY (Telnet/SSH) access:

AccessSwitch1(config)# line console 0AccessSwitch1(config-line)# password ConsolePassAccessSwitch1(config-line)# loginAccessSwitch1(config)# line vty 0 4AccessSwitch1(config-line)# password VTYPassAccessSwitch1(config-line)# login

For enhanced security, consider using an external AAA server .

Step 5: Configure VLANs

Create VLANs to segment network traffic:

AccessSwitch1(config)# vlan 10AccessSwitch1(config-vlan)# name SalesAccessSwitch1(config)# vlan 20AccessSwitch1(config-vlan)# name Marketing

Verify VLANs with show vlan brief .

Step 6: Assign Ports to VLANs

Configure access ports to belong to specific VLANs:

AccessSwitch1(config)# interface gigabitEthernet 0/1AccessSwitch1(config-if)# switchport mode accessAccessSwitch1(config-if)# switchport access vlan 10AccessSwitch1(config-if)# exit

Repeat for other ports as needed .

Step 7: Configure Trunk Ports (Optional)

If connecting to another switch or router, configure trunk ports to carry multiple VLANs:

AccessSwitch1(config)# interface gigabitEthernet 0/24AccessSwitch1(config-if)# switchport mode trunkAccessSwitch1(config-if)# switchport trunk allowed vlan 10,20

Step 8: Enable Spanning Tree Protocol (STP)

STP prevents loops in the network:

AccessSwitch1(config)# spanning-tree mode rapid-pvst

This is recommended for multi-switch environments .

Step 9: Save Configuration

Save your configuration to prevent loss after a reboot:

AccessSwitch1# write memory

or

AccessSwitch1# copy running-config startup-config

Step 10: Verify Configuration

Check VLANs, port assignments, and connectivity:

AccessSwitch1# show vlan briefAccessSwitch1# show running-configAccessSwitch1# ping <device-ip>

This ensures the switch is properly configured and operational . Following these steps will provide a secure, functional access switch setup ready for deployment in your network.
