question on packet tracer

[realm wrecker]

Hi,
I'm new to packet tracer. Would appreciate answer to the question below:
Is there any way to sniff through any specific ports of the devices?
For example,
I've created a simple network to experiment with DHCP allocation and it would be great if there's any way i can look into all the PDUs going out the PC's Ethernet INTERFACE , so i can better understand how DHCP works.

On a side note, it would be great if anyone can direct me to a specific location where all hands on lab files are stored (is there a thread like this at all?)

BTW, I'm really glad i found this forum, and packet tracer too!:)

thanks in advance guys

Try the simulation mode of packet tracer. You can specify which protocols are shown by using the filters in the lower right corner.

In page 746,
you said that the new padded MAC address 0260.d6FF.FE73.1987 is a globally unique address, instead the address started with 0 please explain how it became possible,

It's down to how the address is calculated to pad it from 48-bits to 64-bits. The MAC address is split in half, FFFE is added in the middle, and the global/unique bit is set (b2).
