Comments and observations from CCIE Security Lab Workbook Volume I Version 5.0
ASA Firewall 1.1 VLANS and IP addressing
This section was pretty straight forward; however I did get some inconsistencies from my lab equipment compared to the solution guide. These verification inconsistencies did not take away from the overall objectives of this section.
My verification result (from Switch1):
Rack1SW1#show interface trunk
Port Vlans in spanning tree forwarding state and not pruned
Fa0/21 1,100,120-121,124
Fa0/22 none
Fa0/23 none
****The solution guide says ports Fa0/22 - 23 should display the same results as Fa0/21. Why would Fa0/22 and Fa0/23 show "none"? I haven't figured this out.
My verification result (from Switch2):
Rack1SW2#show interfaces trunk
Port Mode Encapsulation Status Native vlan
Fa0/13 on 802.1q trunking 1
Fa0/21 on 802.1q trunking 1
Fa0/22 on 802.1q trunking 1
Fa0/23 on 802.1q trunking 1
***The solution guide says ports Fa0/21 - 23 should be "auto". I can make my results look like the solution guide by changing the provided intial config for SW2 ports Fa0/21, Fa0/22, Fa0/23
from: switchport mode trunk
to: switchport mode dynamic auto
