Lab 4.1 - Small Enterprise Class Lab

Reflection

Useful Commands:

show vlan

  • This command will show you interfaces (both VLANs and physical ports). Use this to determine the naming schemes of physical ports on a per-switch basis, as it varies from switch to switch.

show run

  • This outputs the entire configuration of your switch into a copy-able format.

To console into a switch:

  • Open up Putty, and navigate to the 'Serial' option on the left column.
  • Open up Device Manager, and open the drop-down for COM ports. Make note of the USB COM port number.
  • In Putty, set the serial port settings to the following:
    • BPS: 9600
    • Data bits: 8
    • Parity: none
    • Stop bits: 1
    • Flow control: none
  • Navigate to the Session tab on the left column, select Serial, make sure the name matches the port, and open the connection.

Troubleshooting

During this lab, we ran into a lot of problems as working with the actual hardware is new territory. One of the first problems we ran into was disregarding Vlan 1. This Vlan needed to be assigned a default gateway address like the rest of the Vlans, and once we had this configured our switches were able to talk to eachother ok.

We also had some trouble getting the serial connections to work properly off the bat. We discovered that the Serial tab on the left column of Putty needs to be filled out before going to the Session tab and opening the connection from there.
