Hi,
I'm not an expert, but I try to answer your question :
1. Q:- Ensure that all Per VLAN Spanning Tree parameters for active VLANs
seen on SW1 are dictated by SW1. In addition, configure VLANS for which SW1
is root, with the following:
-> My solution: I think you need configure SW1 is root for specific Vlan
only (as required in question)
2. Root priority of zero (0).
-> My solution: Yes, you can change Priority for vlans to build Root. For
example, you want to SW1 will be root for VLAN2 & VLAN3, you can use: "span
vlan 2-3 priority 0"
3. Q:- An access port start-up delay, due to Spanning Tree, of 32 seconds
-> My solution : Because Question does not mention to specific vlans, so I
think they ask for VLAN1-> you can use " span vlan 1 forward-time 16"
4. Q:- How to Disable Spanning Tree for VLAN 13 on SW2.
-> My solution: "no span vlan 12"
5. Assume SW2 Fa0/13 will never connect to a switch or bridge.Configure SW2
interface Fa0/13 using a spanning-tree command such that Bridge Protocol
Data Units (BPDUs) are not sent on.
-> My solution: "spanning-tree bpduguard enable". I don't think
"spanning-tree bpdufilter enable" will work because bpdufilter on Portfast
only.
6. CLIENT AUTHENTICATION (Dot1x)
-> My solution: I think you must have " aaa authentication dot1x default
group ....". I have never seen command like "Aaa authentication dot1x login
none ".
HTH,
Chidd
