Started IPExpert Volume 1 Workbook

I have completed the first three labs in the IPexpert Volume 1 Workbook which have been focused on Switching.  While a good number of the tasks are relatively straight forward, some of the tasks introduced some things that I wasn't aware of until looking at the Detailed Solution Guide to track how I went.

One of the commands, that I found interesting which I don't think was specifically mentioned in any of the material I've examined so far (but is there for the looking in the config guide) introduced in one of the tasks is the "switchport protected" command.  It is basically a cut-down version of private-vlans.  The scope of function is switch wide and it basically enables "isolated ports" on the same VLAN - any port or SVI that is not specifically "switchport protected" is basically a promiscuous port.

With the lab exercises, usually initial configurations for LAN switches and Routers are provided which are designed to work on the Proctor Labs equipment and I don't have the same setup which means I need to modify the configs a little.

Below is a pretty simple bash script that uses sed to modify the configs to suit my equipment.


#!/bin/bash

# This script modifies the IPexpert initial configs to match my hardware
# Cat1 + Cat2 = 3750
# Cat3 + Cat4 = 3550
# R1 - R9 = 7200
# BB1 - BB3 = 2611

# Comment out the media-type line

then
    sed -e 's/GigabitEthernet0/FastEthernet0/g' \
        -e 's/media-type/! media-type/g' \
