The report

From Dana Whitfield, Engineering team lead

Engineering cannot reach the file server

Since the weekend network change nobody in Engineering can open the file server. Ben started on Monday and his PC does not even get an address. Sales is working fine.

Impact: Four engineers cannot get at project files, and Ben has not been able to work since Monday.

What you will do

5 tasks
  1. 1.See where everyone is plugged in

    You are on the floor 2 switch, SW-FLOOR2.

  2. 2.Look at the link to the rest of the network

    The file server is not on this switch.

  3. 3.Put things right at the desk

    Make the change that gets Ben onto his department's network.

  4. 4.Put things right on the link

    Make the change that lets Engineering's traffic reach the file server, without cutting off Sales and Voice.

  5. 5.Check your work and keep it

    Look at show vlan brief and show interfaces trunk again to confirm both changes, then save the configuration so it survives a restart.
