The document provides instructions for configuring switch blocks in a network topology using Packet Tracer. It includes steps to configure VTP with two switches as servers, create VLANs on the primary server switch, establish a management VLAN, configure default gateways, trunking between switches allowing only specified VLANs, EtherChannel between distribution and access layer switches including the native VLAN, access ports for PCs in correct VLANs and a garbage VLAN for unused ports, and configure STP with primary distribution switches as root bridges for different VLANs.

1. Switch Block Configuration
Instructions
 Using the PT-Topology-SwitchBlock-VLANs.pkt topology configure the following.
 Type your commands into Notepad and copy/paste them into packet tracer. This
will help you save your work should Packet Tracer crash.
VTP
-----
 All switches will be in the same VTP domain and will use a VTP password.
 Configure DLS1 and DLS2 as VTP servers.
 Configure all other switches as VTP clients.
Creating VLANs
---------------------
 DLS1: Create and name the user VLANs: 10, 11, 20 and 21.
 DLS1: Create and name a Management VLAN (used to telnet into switches)
 DLS1: Create and name a NATIVE VLAN other than VLAN 1 (default)
 DLS1: Create and name a Garbage VLAN (assigned to all unused ports.)
o All ports that are not used (trunks and access) will be assigned as an
access port to this VLAN.
Management VLAN
--------------------------
 For each device in the network configure it to be a member of the management
VLAN.
 Configure privileged and vty (telnet) passwords for each switch.
 You should be able to ping/telnet between switches
Default Gateway
----------------------
 Configure DLS1 to be the default gateway for VLANs 10 and 11.
 Configure DLS2 to be the default gateway for VLANs 20 and 21.

2. Trunking
------------
 Configure trunking between all switches.
 Allow only configured VLANs to be transported across the trunks. NOTE: Packet
Tracer does not allow spaces in the range of vlans Example: 1,10-11,20-21,99
 Configure the trunk link for the NATIVE VLAN using the VLAN number you
created on DLS1 using VTP.
EtherChannel
------------------
 Configure PAgP between DL and AL switches where there are multiple links.
 Configure port-channel load balancing to use source and destination IP
addresses.
 You will need to include the NATIVE VLAN to the port channel interface on each
switch:
interface portchannel 1 (or whatever number you used in PAgP)
switchport trunk native vlan 2 (or whatever VLAN number you created)
Access Ports
----------------
 Configure the appropriate ports on ALS10, ALS11, ALS 20, and ALS21 to be access
ports for the proper VLAN where a PC is connected.
 All ports not connected to a PC or used for trunking should be an access port in
your Garbage VLAN.
STP
----
 Configure DLS1 to be the root bridge for VLANs 1, 10 and 11
 Configure DLS2 to be the root bridge for all other VLANs
