hello all...
another hypothetical ccie lab configuration for you guys:
suppose this type of question:
Configure fas0/17 a 7960 ip phone on voice VLAN 50.. Data VLAN is 10
OK... when out in the field, the "old way" was to do do this:
interface FastEthernert0/17
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk native vlan 10
switchport voice vlan 50
auto qos voip cisco-phone
the "new" way (required on 3560, for example) is like this:
interface FastEthernert0/17
switchport mode access
switchport access vlan 10
switchport voice vlan 50
auto qos voip cisco-phone
in the old way, the port was hard coded to be a trunk and the "untagged" data
packets are sent to the native vlan, also hard coded
for the new way, the port is hard coded as an access port and cdp "figures
out" that the cisco 7960 is plugged in, makes the trunk, sends the data and
voice to the hard coded access and voice vlans, respectively..
for both old and new, qos is macro configured with "auto qos voip
cisco-phone"
having said all of the that.. what do you guys suppose is the correct solution
to that hypothetical ccie lab question?
1. old way? new way?
2. auto qos ok, or fat finger the commands mls qos, mls qos trust cos, etc.. ?
(does not say auto qos is not allowed)
i read so much advice posted in this group saying "do only what the question
asks".. both ways satisfy this criteria.. any thoughts?
