the below configuration is what i would normally add on my cisco switch:
switchport mode access
switchport access vlan 10
switchport voice vlan 20
mls qos trust cos
mls qos trust device cisco-phone
switchport priority extend cos <0-7>
question 1. it would be appreciated if i could receive some advice on the below:
note: i have the cisco book explaining the below but i fail to understand it in practical terms although i do have cisco knowledge!!
- switchport voice vlan vvid - i think the above matches this method
- switchport voice vlan dot1p - when do i use this method ?
- switchport voice vlan untagged - what does this relate to ?
- switchport voice vlan vlan none - I think used when nothing is attached
