Hello Learned Friends. Some help required here!! :-)

1. Whats Layer 3 Precedence mean/do &

what does Layer 2 COS mean(I know

what it does)?

2. When configuring Voice VLAN:-

Whats the trusted mode/ untrusted

mode by CDP request from the switch

access port & how is it achieved?

Does it have any link to the cmd "mls

qos trust cos"? What actually happens

at these steps?

3. Has anyone any clearer steps on this

whole configuration process than what

Mr. Lammle(SYBEX) shows? Maybe with

schematics,flowcharts & diagrams? I'm
